Methane Emissions Naturally

Wetlands emit methane by a natural process. The microbes in the water saturated soil produce the methane. Recently a scientist from GNS Te Pû Ao announced “What we have found is an extremely tough methane-consuming organism,“ that could be used to reduce methane emissions from landfills and geothermal power stations. [14] I thought ‘there lies the solution’, but is it that simple?

Wetland emissions are the greatest contributor to the total airborne methane. About 1/3 of all methane from natural and human activities (anthropogenic) come out of the world’s wetlands. Unfortunately those emissions are getting bigger and can be attributed to higher temperatures and the melting of frozen tundra. It is referred to as ‘climate feedback’. [6]

Methane Matters

A significant number of anthropogenic processes like landfill, agriculture, and fossil fuel, apart from natural systems like wetlands emit methane. It is the second most important greenhouse gas we produce, contributing approximately 167 million of metric tons of methane to the atmosphere each year. [5]

Methane has an impact 25 times greater than carbon dioxide on global warming. From the industrial age methane supplied 25% of the climate-warming effect of greenhouse gases.

Fortunately methane has a much shorter lifetime in the atmosphere than CO2. If we can dramatically reduce our emissions methane will decline relatively quickly. [1]

Wetland Regions

A river reclaims a flood plain some species thrive others don’t.

A wetland is an ecosystem that manages water with a complex variety of plants, soil and aquatic life forms that serves to capture and cleanse water. Human settlement continues to expand into wetlands, draining them to construct a built environment and agriculture.

Cutting drains through wetlands disconnects the natural flow and retention of water. Towns historically built on the banks of rivers. They are now cities with a civil engineering issue with storm water run-off. A solution to wetland draining is to rebuild these wetlands in another area more convenient to humans. These ‘constructed wetlands’ are often built along original creek beds. They could be located on storm water lines or rebuild an area no longer used for agriculture. They regulate water run-off and mitigate flood damage.[2]

Swamp, Bog or Marsh?

Wetlands are often classified by landscape position, vegetation, and hydrologic regime. Wetland classes include marshes, swamps, bogs, fens, peatlands, muskegs, pocosins and prairie pothole.  [22] Characteristics of wetland classes can assist to inform on magnitude of methane emissions. However, wetland classes have displayed high variability in methane emissions spatially and temporally.

How Wetlands emit methane.

Wetlands have a poor oxygen environment and emit methane. In that wet and relatively warm environment the microbes consume oxygen more rapidly than it can absorb in from the atmosphere. The microbes in the soil are forced to metabolize under anaerobic conditions, wetlands are the ideal conditions for fermentation as well as methane production.

The root systems are designed to trap silt – obtain essential nutrients and oxygen – the more silt builds up, the more mangroves can grow,

During anaerobic respiration, other terminal electron acceptors are used instead of oxygen. Nitrate may be converted to NH4, sulfate or molecular sulfur to H2S, CO2 to CH4 methane, ferric ion to ferrous ion, and fumarate to succinate.[3]

Wetland methane production dynamics and fractionations

Fermentation is a process used by certain kinds of microorganisms to break down essential nutrients. In a process called acetoclastic methanogenesis, microorganisms from the classification domain archaea produce methane by fermenting acetate and H2-CO2 into methane and carbon dioxide.[4]

H3C-COOH → CH4 + CO2

Depending on the wetland and type of archaea, hydrogenotrophic methanogenesis, another process that yields methane, can also occur. This process occurs as a result of archaea oxidizing hydrogen with carbon dioxide to yield methane and water.[10]

4H2 + CO2 → CH4 + 2H2O


The diffusion through the profile refers to the movement of methane up through soil and bodies of water to reach the atmosphere. The importance of diffusion as a pathway varies per wetland based on the type of soil and vegetation [12]. For example, in peatlands, the mass amount of dead, but not decaying, organic matter results in relatively slow diffusion of methane through the soil [11]. Additionally, because methane can travel more quickly through soil than water, diffusion plays a much bigger role in wetlands with drier, more loosely compacted soil.

The methane is diffused into the atmosphere through the tissue of plants seen as a release of gas bubbles. The hydrologic stability of wetland soils, as well as the transport efficiency through plants, can affect how much and how often methane is released from the soil. A hydrodynamic study aims to find out if a given flow is stable or unstable, and if so, how these instabilities will cause turbulence [8].

Karla Jarecke and researchers from several universities have been studying wetlands’ impact on methane gas.

Understanding the conditions under which methane is produced and released in wetlands could lead to solutions to reduce methane emissions,” says Jarecke. Wetlands are difficult places to work, so Jarecke and her colleagues made “mesocosms” of wetlands, outdoor chambers where methane emissions could more easily be measured. At their wetland mesocosm sites in Lincoln, Nebraska looked at two common plants; swamp milkweed and northern water plantain.

Comparisons of the methane emissions of the two plant species showed little difference in the field. Soil saturation proved a greater variable in methane emissions.


Ebullition refers to the spasmodic release of bubbles of methane into the air. These bubbles occur as a result of methane building up over time in the soil, forming pockets of gas. As these pockets of trapped methane grow in size, the level of the soil will slowly rise up as well. This phenomenon continues until so much pressure builds up that the bubble bursts, pushing the methane up through the soil so quickly that it does not have time to be consumed by the methanotrophic organisms (discussed below) in the soil. With this release of gas, the level of soil then falls once more. [13]

Environmental factors


It’s a lot warmer in the tropics, so you get a lot of biological activity and more production of methane than from the high latitudes where it’s really cold. We’ve estimated annual emissions totaling over 110 million tons from tropical wetlands versus about 10 million tons from the high latitudes. [1] Those emissions are natural, so they will continue, as long as we don’t drain the wetlands, which do happen.

Further research is needed to understand how varying soil saturation affects methane emissions. This information could be valuable for designing wetland topography that creates hydrologic conditions for increased carbon storage and reduced methane emissions.[9]


Researchers studied the effects of hydrology — or the saturation of the soil. “While the controls of hydrology and plant species on methane emissions are individually well-studied, the two are rarely studied together,” says Jarecke

Heron wades for a meal

Finding plant species that reduce microbial methane production could be a key to better wetland management. For example, plants that deliver oxygen to the rooting zone can suppress microbial methane production. . “Methane emissions likely change as restored wetlands mature. Organic matter from root systems, decaying plants and other materials will build up. This helps restore hydrologic stability,” said Jarecke. Other research indicates that it can take just a few years to restore hydrologic aspects of a restored wetland. However, biogeochemical and biodiversity aspects can take decades or longer to recover.” [9]

Human development of wetlands

Studying large areas like wetlands can prove impossible. So, Karla Jarecke and her colleagues made “mesocosms” of wetlands — manageable, outdoor chambers where methane emissions could more easily be measured. Mesocosms are structural research areas that bridge the gap between lab studies and large field studies. [9 ]

Human activities such as marsh draining for agriculture are increasingly eating away at saltwater and freshwater wetlands that cover only 1% of Earth’s surface but store more than 20% of all carbon. [19]

Stained by tannin from native plants but what else drains into it?

New studies provided by Flinders University show valuable insights into removing toxins from polluted waterways and improving filtration at urban wetlands. One study found a wetland plant capable of reducing Per- and Polyfluoroalkyl Substances (PFAS) in soil and water, and another looked for better urban wetland water flow management during summer. [20]


Methanotrophs (sometimes called methanophiles,not to be confused with Methanogen, ) are prokaryotes (a single-celled organism that lacks a nucleus) that metabolize methane as their source of carbon and chemical energy.

Prokaryote_cell, illustration by Ali Zifan

They are Bacteria (formerly Eubacteria) or Archaea (formerly Archaebacteria), can grow aerobically or anaerobically (with or without oxygen), and require single-carbon compounds (like methane) to survive. Methanotrophs are common around environments where methane is produced, and use the gas as their only source of energy. Their habitats include wetlands, soils, marshes, rice paddies, landfills, aquatic systems (lakes, oceans, streams) and alike. They are of special interest to researchers studying global warming, as they play a significant role in the global methane budget [6], by reducing the amount of methane emitted to the atmosphere. [16][17]

Wai-O-Tapu geothermal pools, Rotorua

In 2007 a methane-consuming microorganism that lives in geothermal areas in Rotorua has attracted international attention for its ability to live in extremely acidic conditions. Discovered by researchers at GNS Science, the bacterium could one day be used to reduce methane gas emissions from landfills. It could also help to cut methane emissions from geothermal power stations. The hardy bacterium is part of the methanotrophs group, but this one is able to live in hotter and much more acidic conditions than its relatives. [14]

Microbiologist at GNS Science, Matthew Stott, identified its international significance.

We knew methane was being produced geothermally at Hell’s Gate and we were puzzled as to why it wasn’t reaching the surface … What we have found is an extremely tough methane-consuming organism that is new to science. It grows happily under extremely acidic conditions in the lab,” said  Dr Stott.

Scientists have always suspected that a proportion of this methane was being consumed by bacteria living in these environments and without them, the amount of methane entering the atmosphere would be much greater.

Ultimately, it may be possible to implant this organism, or a similar one, in landfills and cut methane emissions into the atmosphere.”

Methylococcus capsulatus str. Bath

Fellow microbiologist at GNS Science, Peter Dunfield, who isolated the bacterium, has tentatively named it Methylokorus infernorum, which describes its food source, and the ‘hellish’ location of its discovery, and also a description of a structure within its cell that resembles a Koru. [14]

GNS Science worked with colleagues at the University of Hawaii to sequence the genome of the bacterium. They found its genetic makeup was different to all known methanotrophic organisms.

Later renamed Methylococcus capsulatus it can be used to produce animal feed from natural gas. [14] “Methylococcus capsulatus can be used to make edible vaccines, so-called oral vaccines*>Incomestible bacteria The bacterium Methylococcus capsulatus (M. capsulatus) differs from many other bacteria in that it has little of the substances that can be toxic to humans, among others. That makes it a suitable vaccine candidate. [23]

Geo Thermal Energy

Salton Seismic Trough, part of the San Andreas Fault between the North American Plate and the Pacific Plate

In California’s Imperial Valley near the Salton Sea there is a lot of heat accessible through the tough in the mantle due to gravitational pressure.

Our world’s dependence on fossil fuels has made some resources holders politically and militarily aggressive, at the expense of subservient, resource dependent peoples. Naturally occurring ‘lead pots’ hot mud pools are caused by hot water and carbon dioxide CO2 creating mini volcanoes at the Davis Shrimp mud piles.

Mud pots by the Salton Sea

Permanent Energy Source

They are active, then become dormant, and come up somewhere else.  They sit on one of the largest geothermal generation fields in the world.  They are sustainable and carbon free so it is paying to tap into this hot field resource. Production scientist for Berkshire Hathaway’s Caltech Energy project is Billy Thomas.  ‘25 wells and 10 power plants together delivered 345 megawatts, enough power for 3500 homes.  And they are only scratching the subsurface.’ This field has huge potential, they have the 5000 gallons (Brine) per minute flowing through the plant.

B.H. Cal Tech plant in Imperial Valley giving off steam

‘Geothermal heat comes from our core at 1000° F said to be as hot as the surface of the sun.’ Here wells are drilled between 2000 feet and 2 miles deep were it is only 600° F. They release hot brine [generally applied to highly salted liquid] and steam that spins turbines to produce electricity.  The brine is injected back into the earth where it replenishes the subterranean reservoir.

Geothermal is a prime candidate for a place in a carbon neutral electrical grid.  Geologist Amanda Kolker is programming geothermal energy at the National Renewable Energy Laboratories at Golden Colorado.

Drilling Technology Innovation

Optimization improvements and innovative ideas applied to the geothermal sector in the last decade.  Geothermal wells can also be a great source of minerals.  At the site of geological fracturing, the Controlled Thermal Resources Company is building a 50 Megawatt plant in the Imperial valley.  The salt water rising from the wells is providing almost the entire Periodic Table of Elements.  The demand for electric vehicle cars and the battery’s has made it profitable to extract lithium.  We will produce approximately 20,000 tons of lithium per year.  Four times what the U.S. produces today. 

In the past it had not been enough value to build a plant and operate it.  Lithium compounds are now in high demand.  The rock beneath is naturally fractured and permeated lying at the end of the San Andreas Fault.

Drillable depth resources are not available everywhere at this time to produce steam. But that could be temporary. At the Forge Project in Utah they are the piloting a drilling project for Enhanced Thermal Systems.

Drilling for Heated Rock

The plan is to drill two wells into low permeable rock, fracture it, (by pressure or seismic blasts I assume).  Pump water into the cracks with one well then collect and pipe the steam up the other well to the surface where it could be directed to power turbines.

Oil drilling veterans are now drilling for hot rock not oil

Cindy Taft of Huston based Sage Geo Systems Engineering, has a plan to drill one well vertically, then horizontally into sedimentary rock at two levels and fractured of rock in between.  Water is fed down, heats to stay in the knees taken up through a concentric pipe within this very same well.  With the experience of seismic fracturing for oil and gas extraction, they can control the seismic distribution in fractured rocker to local conditions.

Seismic monitoring is in place about the drilling project site.  Because fracturing explosions have set of earthquakes in specific locations from South Korea to Indonesia where a gas project released mud, threatening to become an environmental, public health  disaster. (Further reading below for more.) ‘We don’t need stimulation from most Geothermal drilling plants. When we do need stimulation (explosion), avoiding zones of seismic risk is a necessity for controlling devastating consequences.’ Cindy Taft said.  ‘Fracking’ experience mitigates seismicity consequences, the intermingling of fuel deposits with aquifers are extreme incidents.

Drilling Innovation Business

The geothermal boom has driven a lot of innovation in the drilling business.  In Huston ‘Particle Drilling’ is partnering with a big player in N.O.V. to push Drilling Technology into a whole new era.  The bit they are developing fires 12 million steel balls out through four nozzles. ‘It will obliterate the rock material,’ said Jim Schilling of Particle Drilling.

‘It costs about $100,000 a day to operate a drilling rig.  We are at the tipping point where we can go from 60 to 80 feet per hour to 100 feet, then we move that economic efficiency to be able to drill geothermal wells anywhere,’ said Tony Pink of NOV.

In 2020 renewable energy made up to 12% of U.S. Energy consumption with geothermal providing only 2% of that share.

Carbon Sequestration

Carbon sequestration puts carbon into soils. Australia has the most number of soil carbon projects, the most innovative approach to issuing /measuring carbon credits for carbon sequestration. The projects aim at taking as much as possible greenhouse gas or carbon dioxide from the atmosphere. Methane from cattle burping production is the number one source of greenhouse gas emitted worldwide. It stays in the atmosphere for about 12 years. Listen that emitted by both fossil fuels but potent. Agriculture will pull carbon dioxide out of the atmosphere part of Australian government pledge to be carbon neutral by 2050.

How is it done, and what is in it for farmers?

It is what they are growing in that is the focus – soil health

Their properties have olive tree orchards; also table grapes, stone fruit and two dryland cropping operations in canola, wheat, barley, legume crops – chickpea and sorghum.

“It is what they are growing in that is the focus – soil health, differing crop rotations, less turning of the soil and replacing fertilizers with home-grown fertility inputs,” says Harry.

Auditable process must have excellent farm records, for 10 years minimum; Items, livestock counts, fuel imports, fertility inputs. The project registered with the Australian government Clean Energy Regulator. Having set a base level carbon in its soil at 2019 its first audit is done in 2024.

Soil life

“Looking at the trees growing above ground which is slow, to expect the carbon levels to grow in the ground any quicker is wishful thinking. Slow, long, steady process that very cumulative process, anticipating they’re going to shift the percentage more than 1% over 10 years.”

If Harry can prove but they have increased the carbon level above what was already in the soil well his farming methods he will be able to claim tradable carbon credits. One credit for every net tonne of carbon dioxide equivalent that is abated. At about AU$49 in December 2021, up from $16 per ton at the start of the year.

“Farmers absolutely can make money from soil carbon. He develops solar projects for farmers to register and trade in the Australian carbon market. Farmers are emerging as price makers not price takers.”

Nils Olsen – the first farmer to earn carbon credits through the Emissions Reduction Fund (ERF) for boosting soul carbon.

The first soil carbon project was registered in 2015, it took five years for the first 50 so carbon projects to get onto the ERF but in the last 18 months that has grown fourfold.

The methodology for making carbon credits from soil is arguably the most administratively dense, most technically complex and the most costly method for getting carbon credits issued in Australia.

“Australia has 9 million hectares of agricultural land,” says Angus Taylor, federal Emissions Reduction Minister, “a very significant carbon sink.”

“The amazing thing about absorbing more carbon,” Shayleen Thompson, Clean Energy Regulator, “it is a way of reducing carbon emissions. It actually sequesters the carbon from the atmosphere into the soil. Which is why you can get carbon credits.”

and inspected
Soil samples are drilled

To get more farmers involved in the carbon market, the government is relying on soil testing becoming a lot cheaper, and a new methodology. A set of rules to help farmers get built-up carbon in their soil and get carbon credits. Methods include; changing stock rotations retaining crop stubble rather than burning off, making irrigation systems more efficient, and using forested land to sequester more carbon. Land owners are encouraged to build soil carbon, diversifying their farm, improving the productivity and operations, and making the property more resilient to droughts.

Also an opportunity for consultants as last heard they’ll charge farmers thousands to sign up to the scheme. “Complexity agents, help farmers participate in the scheme and deal with the paperwork and administration if the farmer decide they cannot manage it period,” said Ms. Thompson

PM Scott Morrison says, “Australian farms could offset as much as 17 million tonnes of CO2 equivalent by 2050, generating $400 million for farmers in the process.” The ERF is not the only way they’re turning carbon into a commodity.

Stuart Austin, runs the McLeod family owned Wilmot Cattle Company. “It has been measuring carbon content across its farms for years. 2013 to 14 management changed from set stopped operation to a much more intensive rotation, longer rest periods. That is when we saw a real shift in the organic carbon levels and other component nutrients. It has always been part of the mix,

we see that carbon drives the whole system.

Wilmot base lined its carbon across two properties with the ERF in 2016. The ERF is the gold standard, but most expensive and most rigorous to participate in. It would not recognize the gains in carbon made prior to signing up to base-lining. We wondered if we had seen the big shift and had missed that opportunity, had not been able to capitalize.”

          With Toby Grogan, Stewart investigated other carbon market options.

“Guys from the Regeneration Network in the U S said they could do something with the data. Using satellite imagery and Wilmot soil data it said it could prove the soil carbon had increased. Quite a debate about the rigor of it, the integrity of it, and did we think it would stack up to the court of public opinion.” Wilmot took the deal to the market and software giant Microsoft announced it paid $500,000 to the company for the carbon it had sequestered in the period 2017 to 2020.

By the time they took the methane emissions which equated to 10 or 12,000 tons of NH 4 over three years on the two farms. That brought them back to 43,000 tons of CO2. Because the carbon was purchased by a U.S. company, the amount will not be counted in the Australian target.

Before the end of the decade the National Farmers Federation (NFF) wants $5 billion of the farm gate income to be generated by ecosystems services. Tony Mahar NFF, stated “The soil carbon is not the silver bullet that will reduce emissions or become a total income stream for farmers. But what it can do is to be part of the solution. What we need is more methodologies and more practices for farmers to engage in that process.”

“Arguably producing the most nutrient dense grass fed beef.” Stuart Austin went on to say, “If we can improve souls by even 1% across land our farmers manage, that will give a profound productivity benefit and an abundant revenue stream, producing just as much food as in the past, and it will make a significant contribution national account offsetting global emissions.”

Indigenous Australian aboriginals have an ancient method

Traditional burning practices prevent raging fires that fill the atmosphere with tones of carbon. Carbon abatement programs have been running in northern Australia for many years. Kristy O’Brien journalist on Tiwi Islands were the Arafura and Timor Seas converge lie the Tiwi isles (Ratuati Irara – two islands).

Satellite image of the Tiwi Islands, Bathurst, Melville and Australian mainland Northern Territory (left to right)

Willie Rioli Ranger Supervisor with duties including controlling weeds, feral and bushfire controls.  Northern Australia’s tropical savannas are amongst the most fire prone ecosystems on earth with up to half of them including the Tiwi islands prone to bush fires.  Uncontrolled fires can destroy sacred sites, biodiversity, infrastructure and cause major environmental damage. Willy supervises from the air at the ranger burning program.

They plan to cover large tracts of land to drop fire and making sure burning is dispersed and effective. Ancestral knowledge is applied to reduce the severity of hot uncontrollable fire in the Goonapendri – the dry season steps in September.  Spot fires help maintain the open vegetation structures that Savannah plants and animals evolved in.  Being aware when cover plants and grasses are ready to burn these cool burns are expensive practices in remote areas like these. 

The Tiwi rangers have found ways to monetize the burning. Looking at carbon, most emissions are generated from uncontrolled fires that sweep through remote parts of the islands from late August that produce greenhouse gases that threaten biodiversity.  Reducing the extent of fires represents an opportunity to earn carbon credits.

“It is not only about earning money it is about looking after your country, looking after the animals and birds and bush tucker,” said Willy.

 The deal was struck with Epex Gas Company four years ago.  A relationship can be made between indigenous interests and the mining sector.  The Tiwi Group produced 42,150 carbon credit units in their first year.

“It enables them to gets out to country and buy equipment, having that supports is really hopeful,” explained Willy.  The Indigenous Land and Sea Council has overseen the Tiwi management diversity program.  It wants to see more groups signed up and operating at a level recognized by the Clean Energy Regulator and the relevant land council to be eligible to earn carbon credits.

There are some areas where there is abatement of carbon soils and indigenous capacity is not reached or realized. There are some areas where new methodologies can be developed with desert ecosystems of lower rainfall where offsets could be generated. Perhaps that’s not as much as in with the wetter parts of the country.  Since 2012 there are 32 owned and operated Savannah fire projects in Australia.  Combined they abate one million tonnes of carbon.  This year and they have offset 1.6 million tons of emissions generating $95,000,000 worth of credits that encompasses 3.6 million hectares of country.

Charles Darwin University native animal monitoring

There is significant interest from some other countries of similar terrain like Africa, South and North America.  Rangers from Arnhem Land travelled to Botswana, California as well as the Kimberly to talk with the people who are interested and share knowledge.

Unseasonal rain in May and June made for the worst conditions for fire season that the Tiwi Islands have had for the last 12 years.  Rangers did their best to protect assets and minimize the impact on carbon emissions.  But the environmental impact and comes in different forms.  Riders have been part of a program that monitors how fires have affected nationally endangered species in uncontrolled fires.

They have been blamed for the decrease in small mammal species in the Northern Territory in the past three decades.  The Charles Darwin University is monitoring the program to see if the Tiwi control burning program improves the outlook for the threatened species.  The rangers are impressed to hear their work looks to improve the country. 300 traps are set to catch animals that year for ear-tagging.  Results are proving that the cool fire controls are improving the small animal numbers, including the northern brown and common coloured possum.

“In general it is about keeping the country healthy. I want to see the possums and bandicoots for years to come,” said Willy. 

“The indigenous program here produced some 7% of Australia’s carbon credits; the system added some $25,000,000 per year. There is room to generate more credits and demand a higher price.” Joi Morrison, of the Indigenous Land and Sea Council points out. “Harness that connectivity of knowledge, indigenous people are very well placed to put a premium price on credits. This is not just about carbon, this is about knowledge, 5000 years of connectivity and importantly this is about ancient knowledge to instil in future generations.”

Willy Rioli, “Wants to see a woman’s ranger group and would support it.”

The A.W.U. wants a minimum wage for seasonal agricultural workers. Farmers prefer the piece-rates as an incentive to work quickly and productively. The evidence arises of exploitation of unskilled foreign workers without any legal representation.

Australia has refused the part of the pledge to reduce methane emissions at the Glasgow’s UNCCC summit.

It is considered to be one of the most potent greenhouse gases and the biggest contributor to global warming behind CO2.  But methane accounts for about half of Australia’s emissions from livestock.

Rachel Kyte, UN climate adviser states, “If we can cut the methane emissions by 2030 we take off the acceleration of global warming away.  Why Australia is not part of that beats me.” More than 100 countries signed up while Australia sided with Russia, China, India and Iran some of the biggest global emitters. 40 countries signed up to phase out coal for electricity including the major coal issuing countries like Indonesia.  Some of the world’s biggest coal producing economies like the U.S., India, China and Australia were missing in the deal.

Tasmanian couple producing Red Wagyu beef go up and beyond carbon positive.

“We need ruminants in grazing to store carbon”

Aiming to sequester more carbon then their beef cattle operation emits. They are using soil and hungry cattle to take CO2 out of the air.  Sam and Steph Trethewey bought these 175 hectares farm near Deloraine in northern Tasmania two years ago.  Good soils and reliable rain meant they could easily continue rearing cattle conventionally.  Climate change concerns of the Sedge to regenerative farming practices.  With a three year old and a 12 month baby “What is it going to look like to them?” Steph asked.

Some vetch and clover

They use mass fodder plantings for the climate friendly formula to remove CO2 from the air and sequester it into the soil.  That carbon improves the soil to grow more plants.

“I think regenerative practices of a massive opportunity and they are key enabler to store more carbon back in your soils.  It is the future and that is something we absolutely have to do, …  the agriculture sector can make a difference,” says Sam.  They did that to their own greenhouse friendly grass fed beef brand.  The bulls are relatively unknown Red Wagyu.

“They marble on long grass, and looking at the data from the Wagyu Association they have up to 20% higher growth rate than the backs [Wagyus].”  They are countering the industries’ bad press by assuring customers that, ‘eating red meat is not bad for the planet.’  Their story is that cows are part of the solution.  “Cattle have been portrayed as climate villains because of the methane emitting burps. On a beef only enterprise it can be 70% of the greenhouse gas total load.  Beef production in the U.S. is the new oil.  The industry is finding its feet and talking back as to what it is to those allegations.  I believe regeneration practices are agriculture’s answer to the climate crisis.  That is because this practice needs short bursts of high intensity grazing.  We need ruminants to store carbon and that flips the whole argument on its head.  We need the cows to eat the top of the plants to regenerate that growth and turbo-charge the soil with the plants.” Sam explained.

Australia’s red meat industry has set a target to be carbon neutral by 2030.  Sam and Steph plan to exceed that, “When you look at the enormous challenge to curb the climate of the planet.  Carbon neutral is not good enough, we’ve got to be a net positive, the extra mile.”  Can you get there?  And how quickly?  “We’re hoping in the next 12 months to be honest.”

The Tretheweys in 2019 were the first Tasmanian farmers to register a soil carbon project with Net Emissions Reduction Fund(ERF). To establish base line numbers, core samples were taken across the property down to a metre.  It is the most accurate method and the most expensive.  It is the only acceptable measuring technique under the protocol of the U.N. Paris agreement.  “We decide to go with it because it is the most accepted and the most rigorous method.  We can build our brand with it.  When we stand up talking about how we tested for carbon we wanted a system we can back it up with, no one can question, its at the top of its game,” said Steph.  As carbon credits mature, carbon credits that are worth around $20.00 a tonne now, need to rise.  Sam believes theirs will be sort after.  The cheaper third party not so verified credits, not audited they will be on the voluntary markets and will not attract a premium.  Theirs will be more robust and will be in high demand.

Assoc. Professor Matthew Harrison of the Tasmanian Institute of Agriculture says, “The main way the Tasmanian farmer can gain income from carbon farming is simply through good practice.  Carbon farming results in improved sustainability which results generally in improved productivity.  Matt is known internationally for his work in climate change adaptation and greenhouse mitigation in agriculture.  He warns that some carbon emission reductions schemes in Australia are flaky.  You’re getting observations of stored carbon figures from virtual satellite measurements.  When they are grounded with traditional agronomic advice from agricultural science you can see through those estimates of the potential carbon sequestration seen through that satellite is unrealistic.”

Botanist Robyn Tait was hired to speed up carbon building’s simple formula, grow as many plants as possible.  Plants suck up CO2 and make sugar which feed the fungi and bacteria who make humus and organic matter in the soil and that stores the carbon down there.  The seed varieties that they use look like muesli.  A summer mix with 23 seed varieties Sam and Robyn sat the soil has already improved with soil moisture and fertility.

Plant tap root penetration of 40cms.  Planted in February that through the hard compaction layer.

Brian Morice worked on the property for 40 years regularly spreading fertilizer. “ I thought they would be here for short time,  and they will be gone,  because it was totally against what I was taught,   now it is going to work. Before I was giving them six months. Seeding multi varieties six months ago and you dig down now and you find roots at1/2  metre deep.  You think well something is doing it.”

They launched ‘Tas Agco Beef’ this year.  It started with a dream to produce carbon positive beef.  In the post Climate conference in Glasgow world beef producers fear being penalized by the export customers of being unable to prove they are de-carbonizing the industry. 

This is why key industry figures have visited Deloraine.  It might be a shaky start-up producing just three carcasses of a week, but it valley can easily scale up.  They are buying properties and building the herd to 2000 head.  The key customer is ethical, humane and sustainable and now asking about concerns that are voiced to city butchers about climate impacts. The commercial butchers are proud to be stocking climate mitigating friendly products and understand what they are trying to do.

Beef and Livestock Australia a set up a spreadsheet to track farm emissions.

While Sam and Steph say soil carbon will get them to their net positive target, they also want to decrease emissions from their cattle.  They are participating in the methane inhibiting red seaweed feeding trial. Matthew Harrison’s team will trial half of the Trethewey’s herd on bio-char and the other on methane inhibiting sea weed.  In the meantime there’s a debate as to how much carbon can be stored in the soil, some say ‘huge amounts,’ others ‘wildly overstated.’ Traditionally thought to be a very slow progress but actually it is a quick process and we can add an inch to soil in a couple of years,” said Robyn Tait. “We need to do this in scale and we need to get bigger producers doing this in a big way,” says Steph Trethewey.

Australian carbon prices are traditionally low compared to those internationally. Like the value of most commodities that has gone up.  E. U. Futures are going beyond $100 per tonne.  Only $20 a tonne purchased through the Federal government’s ERF. New Zealand and the EU have driven up prices by the government policy.  The higher the target the government sets itself the higher the price the market will attract.  Dr. Tim Moore of Regenco, natural capital specialists says demand will come from companies who have high carbon futures obligation or higher emission’s targeting policy.  Bi-lateral arrangements offer possibilities for markets with Australia and Indonesia or New Zealand or Papua New Guinea: volume is the key, big market demand.  Grain is being rationed in overseas countries, bad weather is hitting production areas and Russia has put quota on fertilizer exports.

Victorian winery on track to be carbon neutral without offsets by 2025 

ABC news Reporter: Billy Draper

Tahbilk is situated on the traditional lands of the Taungurung people and was established as a winery in 1860. On the banks of the of the Goulburn River in north-east Victoria, is one of the few vineyards in Australia to be certified as fully carbon neutral.

The operation near Nagambie, where Hayley Purbrick’s family has been making wine for five generations, offsets all the carbon dioxide it creates. 

The winery’s journey to becoming carbon neutral began in 1998, when trees were planted to revegetate the property, and in 2008 it undertook its first carbon audit to start looking at ways to lower its carbon footprint.

“It’s just the right thing to do,” Ms Purbrick said.

“I think if you’re a business and you’re not doing these types of things then you’re missing out on the future of the next generation.”

Over the past decade, the business has reduced carbon emissions by 45 per cent by using solar power, revegetating areas and using heat-reflective paint on its restaurant roof.

“They use it on rocket ships,” Ms Purbrick said.   

Key points

  • 120 hectares of land has been revegetated
  • The winery offsets 97 per cent of its emissions without buying carbon credits
  • Since 2008 it has reduced emissions by 45 per cent through carbon auditing

Air capture machines suck carbon dioxide from the atmosphere.

Are they part of the solution?  

ABC Science   By technology reporter James Purtill

On a barren lava plateau in Iceland stands an entirely new kind of industrial facility that sucks carbon dioxide from the air and traps it in stone.

The world’s first commercial direct air capture (DAC) plant is designed to remove thousands of tonnes of greenhouse gas every year and then inject it deep underground.

These first plants are coming online, with the Intergovernmental Panel on Climate Change (IPCC) recognizing that, even if the world reduces its ongoing emissions as quickly as possible, there will still be too much CO2 in the atmosphere to avoid catastrophic levels of global warming. The world needs to both reduce future emissions and remove historical ones to reach a safe climate.

Why not just plant more trees?

When Deanna D’Alessandro, a professor of chemistry at the University of Sydney, encountered the idea of mechanical carbon removal, she wondered if there wasn’t a simpler solution.

A tree, of course, is a pre-existing and relatively cheap technology that sequesters CO2 in wood and other biomass.

When scaled up, it’s called a forest.

When Deanna D’Alessandro, a professor of chemistry at the University of Sydney, encountered the idea of mechanical carbon removal, she wondered if there wasn’t a simpler solution.

A tree, of course, is a pre-existing and relatively cheap technology that sequesters CO2 in wood and other biomass.

When scaled up, it’s called a forest.

“My first thought was why not plant more trees,” Professor D’Alessandro said.

“And then I did the numbers and stood in awe of them.”

By her own calculations, using reforesting to capture Australia’s CO2 emissions for two years (about 1 billion tonnes), would require an area of land equivalent to the size of New South Wales.

DAC could do the same with 99.7 per cent less space, she said.

“Not only do we not have the land, we don’t have the water to achieve natural sequestration.”

Mark Howden, director of the Climate Change Institute at the Australian National University, agrees.

“The science is very clear that to keep temperatures down to [an increase of] 1.5C, we not only need to reduce greenhouse gas emissions, we also have to absorb CO2 from the atmosphere,” he said.

“It’s increasingly clear that doing that just from planting trees and relying on farmers and soil carbon is not enough.”

How does direct air capture work?

DAC is just one of several proposed technologies designed to remove emissions from the atmosphere, which also include repurposing offshore oil and gas platforms to grow seaweed and turn it into fire-resilient bricks.

So, DAC works a little bit like a household dehumidifier, but instead of stripping water out of the air, it removes carbon dioxide.

The greatest challenge, says Professor D’Alessandro, is processing enough air to capture a significant amount of CO2, given the gas makes up just 0.04 per cent of the air we breathe.

“To be frank, it’s been one of the most interesting scientific problems in chemistry in the past 10 years,” Professor D’Alessandro said.

There are generally two approaches.

In the first, a fan pulls air into a structure lined with thin plastic surfaces that have potassium hydroxide solution flowing over them.

The solution chemically binds with the CO2 molecules, removing them from the air and trapping them in the liquid solution as a carbonate salt.

In the second method, a sponge-like filter absorbs CO2 and is then reheated to release the gas into storage.

In the case of the plant in Iceland, the captured CO2 is injected about a kilometre underground into volcanic rock.

Over two years, it reacts with the basalt to form a solid carbonate material.

But underground storage isn’t the only option, Professor Howden said.

“Probably the dumbest thing we can do with captured CO2 is put it in the ground,” he said.

“To my mind, if we’ve gone to the bother of capturing CO2, why not treat it as a resource?”

Another DAC company, Canada’s Carbon Engineering, plans to use captured CO2 as an input to make carbon-neutral synthetic fuels that can substitute for diesel, petrol or jet fuel.

Other proposals include using CO2 in cement production and plastics manufacturing, which could make buildings and water bottles carbon negative.

Is this any different to carbon capture and storage?

CCS involves capturing CO2 at the site of production, such as a gas liquefaction plant or coal-fired power station, and then pumping it deep underground.

Instead of filtering the air, it filters emissions from a smokestack.

Although the Australian government has singled CCS out as a priority technology for emissions reduction, critics have said it’s a failure.

One of the major problems is CO2 leaking from underground reservoirs.

With DAC, there’s a much lower risk of leakage, Professor Howden said.

“With standard CCS you’re restricted in the geology to somewhere close to the point of combustion, whereas you can put a DAC system anywhere, so you find geology that’s suitable and locate it there.”

How much CO2 needs to be captured?

DAC would need to be enormously scaled up to be useful.

Even if the world reaches net zero by 2050, it will still be necessary to remove 5 to 14 billion tonnes of CO2 per year from the atmosphere from 2030 onwards to keep global warming below the 1.5C limit set by the Paris Agreement, according to a University of Melbourne report.

The DAC plant in Iceland, which is the world’s biggest, can capture and remove 4,000 metric tonnes of CO2 a year.

That’s about 10 million times less than annual global emissions.

At our current level of emissions, humanity is cancelling out the plant’s yearly efforts every three seconds.

Water: Why it Matters

Without water there is no life. If it does not flow out of the tap from the municipal dam or high mounted tank we have to catch the rain or pull it out of the nearby stream. In arid areas that nearby stream may be many meters underground. Water from these aquifers takes years to filter down the subterranean system. Once it is pumped onto the surface and used for irrigation or domestic consumption most of it finds its way into the sea[1]    

Underground water is replaced by seepage from mountainous snow and ice melt and rain. Ancient civilizations engineered sophisticated collection systems for catching and holding rainwater in arid zones. The Nabataeans controlled the water supply by use of dams, cisterns and carved channels in the rock faces surrounding the city of Petra. Although it did experience flash flooding which the Siq (shaft naturally funneled into the Wadi Musa[2]

Apparently an earthquake in 363 AD destroyed much of the infrastructure and the city and its trade declined.

The driest regions of Earth give clues to water capture and retention. The infamous Atacama Desert of Chile has extremely low humidity. There rocks support endolithic microbes on their surface which are the source of water. David Kisailus from the University of California, Irvine, located bacteria on gypsum in the Atacama. The rock predominately hydrated calcium sulfate was etched by the cyanobacteria and dehydrated it to anhydrate. Spectroscopy revealed that the bacteria secreted an acidic extracellular deposit that may have altered the chemistry to release the water from the rock.[3]

Another approach observed in the high sand dunes of the Atacama is the water catching technique of the people of Falda Verde. Mostly the only moisture to fall on the western slopes of the Andes bordering the Atacama arrives as mist from warm ocean air condensing in the cool high altitude. Nets are erected to catch the water droplets which are channeled into tanks. Across the Atlantic the highly specialized beetle Stenocara gracilipes or Namib Desert beetle survives by collecting water particles on its lumpy textured back. To drink it faces up wind raising its body angle to 450, water gathers on its hard outer wings with Hydrophilc lumps.

When enough water combines into droplets big enough to overcoming the electrostatic attraction of the lumps and the 30 km/h sea breeze, the drop rolls down the waxy hydrophobic channels into the beetles’ mouth parts. Their performance is that efficient they can collect water from dew settling.[4] Some of the tenebrionidae have hairs around their necks to transfer the droplets around to their mouths.

Man controls the majority of Surface Freshwater

Most of the world’s fresh water is found in icecaps and glaciers, 30 percent is in artisian basins. Reservoirs and constructed dams account for only 0.38 percent of water storage on the Earth’s surface, but they manage 57 percent of the change of all fresh surface water availability. [5] Fresh water is threatened by over development of impermeable surfaces like concrete, bitumen, and buildings that increase run-off into storm water drainage. The Earth does not have the opportunity to soak it up in plants, soils, or seep into aquifers. The vast majority of Earth’s fresh water is unavailable to its living species.[6]

The scale of human intervention has dramatic effects on water shortage in natural ecosystems. Till recently the Menindee lake system had no water flow in it for five years.[7]

Fish kill adjacent to Menindee Lakes

“Of all the volume changes in freshwater bodies around the planet – all the floods, droughts and snowmelt that push lake levels up and down – humans have commandeered almost 60 percent of that variability,” Laurence Smith environmental scientist from Brown University.[8]

The Human interference with the world’s water cycle is on a par with the impact on our atmosphere and land habitat. As the world warms the water in lakes, rivers, streams and our dams will evaporate to a greater extent. The water vapor once airborne can move usually to a cooler air source to condense as snow or rain. Some will fall on mountains and return to water courses to be returned to the water cycle but the moisture that falls into the saline oceans is no longer of use to most of us. 

Almost all of the longest rivers have water controlling barriers; only 21 have a clear passage to a sea. Animals depend on fresh water habitat like; crayfish, mussels and fresh water spawning fish are disappearing at a faster rate than marine species and even faster than rainforest species. Over one billion of the human species want for clean drinking water and more than twice that many people rely on unsanitary waste disposal[9].

Repercussions for rivers

River flow from and through watersheds (catchment landscapes) picking up sediment, nutrients and pollution, carrying then depositing them down stream. Chemicals like nitrogen, phosphorous and potassium common in fertilizers, road sediment and household drainage accumulates at the low areas. These additions will influence the natural balance of plants and animals.

Dams interrupt free flow into standing pools, likely straightening and deepening a river bed. The impact can reduce water quality, block fish migration, and inhibit reproduction of freshwater species.

 Chemicals from agriculture, industrial sites, sewerage and urban run-off can pollute water courses. Detection can be subtle only apparent after years of toxic accumulation resulting in disease and deformities in amphibians, and cancer in people. The rivers of the Colorado, the Murray have numerous instances of water shortage disasters. After 15 years of diminishing snow falls on the Rockies Lake Powell serving 40 million people has been draught stricken since 2012. Interstate authorities argue over water distribution from the Tennessee River and the Chattahoochee  and the Flint  and the Apalachicola Rivers.[10],[11]

Lower reaches of the Murray River in drought

Pumping water out of underground aquifers, rivers and creeks, and wetlands for irrigation, urban consumption or industrial purposes can decimate water sources. Wildlife is can be wiped out and human communities reduced to arid or salt clogged conditions.  With the increase of climate affecting chemicals in the atmosphere rainfall is less predictable. And extreme weather events are most likely to occur; flooding will be more hazardous, and dry spells longer and more intense. Humans have choices and alternatives, wild animals depend on freshwater in their habitat.


Where does the responsibility for your freshwater lie?

The individual user could check the source, the supply infrastructure and individual receptacles are free of introduced or in-built contamination. The Romans never identified lead water pipes as a hazard.

The water supply company (or authority), the local municipal council, state governments are usually considered responsible. Some councils simply gave up and supply commercially package drinking water after ‘fracking’ practices were used to separate natural gas from the ground structure.

Freshwater – Biodiversity

Eco-systems in freshwater host populations for 12 percent of animal species and 40 percent of fish. These habitats have a large array of fish, amphibians, mollusks, crustaceans and insects which provides sustenance for large flocks of endemic and migratory birds. Plants are an essential contributors to the freshwater eco-systems giving food and shelter for animals.

However because they are vulnerable to run-off pollutants and drainage, they exhibit up to 15 times greater extinction rates than in marine habitats.[12]

After three years draught, floods from northern states brings water flow to Minindee lakes 2020

The diversity of freshwater habitats is affect by the local topography. Rainfall at a river’s headwaters [source] flows downhill through the area where all water from tributary streams drain into the same river system known as its water shed. This moving water flows through varying geography. The less steep the slope in the land the longer the water will seep into it. The slower moving water courses see a variety of wetlands; marshes, sloughs, soaks and bogs, or seasonal pools known as vernal pools.

Where no outlet is found water accumulates as a pond or lake. Some water will infiltrate the ground and contribute to the subterranean water system.

Ice and snow can contain water for centuries before melting to release water at high altitudes to add another diversity to water cycles.

Freshwater Habitats


High altitude rivers become aerated

The steepness of the gradient, preferred by hydro engineers, controls the composition of the water course. At speed water forces all but large rocks to roll and move down stream. The size of particles like pebbles grit and silt settle into the river bed as the water slows.

Locations below cascades have excellent aeration and waste is moved on. Such a site suits salmon egg lodging between pebbles. Shallow pools with slow currents suit small fish, crustaceans, amphibians and mollusks. Consequently wetlands attract birds and small mammals. Riparian vegetation affects microhabitats providing shade and cooling and protection within the root structures. Plants attract insects which encourages microorganisms in the decaying leaf litter. Each stream has dissolved minerals eroded from the geology it flowed through which influences the types of wildlife it supports.

Often thought of as closed systems like a pool with little outflow. Where a water outflow does not exist, fish, mollusks, crustaceans and all but large amphibians stay in them. When there is little flushing action toxins are accumulate, as can invasive species of plants or animals which frequently out compete with local natives.

Nature’s drainage areas provide habitat for fish, mollusk, crustacean and amphibian nurseries. We usually identify the wading birds foraging amongst the tussocks. These flood areas are extremely effective filter systems.

Man Made Water Systems


A soviet scientist, Vladimir Vernadskiy in 1926  wrote about his concept for a biosphere. It was a closed ecological system in order to support life separated from Earth’s conditions. The sort of infrastructure you would need to colonize another planet. I recall the water cycle in a 1980’s biosphere becoming that rich in nutrients that the only way to purify the water to an acceptable clarity was to run the water over plain glass panes where algae formed and filtered out the unwanted nutrients in the algae’s slimy layers.

The atmospheric containment was that good that oxygen levels reduced to high altitude levels and carbon dioxide concentration was 45 percent higher than normal, largely due to soil bacteria reacting to their confined habitat exhaling huge amounts of carbon dioxide.

Concrete used in the biosphere construction contained calcium hydroxide, the excess CO2 instead of being processed by the plants and photosynthesized into oxygen, reacted with the calcium hydroxide in the concrete walls to produce calcium carbonate with water.

Ca(OH)2 + CO2 à CaCO3 + H2O

Quite unpredictable as was the mass death rate of most of the plants animals and insects selected to inhabit the biosphere, some species thrived, like cockroaches. The large introduced ant found its way in and dominated all other ants. Vine species like the morning glory chocked the life out of all other plants. The 8 scientists were unable to sustain an adequate production of food despite having all prescribed agricultural requirements. Additional seeds stocks and food was imported at critical times. The natural systems it appears are not that simple or obvious.[13]


Dams are seen as a necessary structure to provide reliable clean water and produce ‘clean’ energy from the water fall driving turbines. Let us look at the infamous Three Gorges Dam project in the upper reaches of the Yangtze River, Central China.

People relocated: 1,000,000

Factories submerged: 1,600

 Dams interrupt the continuous flow of rivers but at times of flooding they may have to release more water through the spillways to ease the pressure on the dam wall structure.

That structure halts anadromous fish like salmon trying to swim upstream to spawn. Wealthy counties can build fish ladders like a series of locks or rapids.

The seasonal pool depends on underlying impermeable soils, often derived from volcanic flows. Spring is usually when these bodies of water are full. They provide a growth season for plants and animals. Peculiar plants have air containing stems that are buoyant, others have leaves that have adapted to float. As the water evaporates plants set seed which form concentric rings of flower shows. During the dry months amphibians dig deep into the mud to time their dormant phase.

Migrating birds will look to the vernal pools for nourishment and resting places alone their routes. These types of wetlands are threatened by drainage for agriculture or urban development, bush clearing for fire prevention, off-road vehicle use and most human activities. Legal protection for endangered species may give some leverage for protecting these aquatic eco-systems.

Water Cycle

The process and forms water takes on its journey around the Earth, from our oceans where heat from the sun evaporates the water as vapor into the air. At the molecular scale the water molecule that leaves the surface of the liquid draws another molecule to the surface where it heats and is also evaporated.

The minerals or salts the water molecules were carrying are left behind, increasing concentrations in the water body. The air above becomes progressively more humid.

The airborne water vapor travels upward and perhaps inland carried by air currents. Going higher the vapor molecules becomes colder, condense, cluster around suspended particles and form into clouds. Water vapor is clear so invisible in normal conditions, water droplets in clouds can be seen. When the mass of water is great enough precipitation occurs, as rain, or snow, or ice depending on the surrounding air temperature. The water descends and gravity acts to make it flow through the topographical landscape. Individual droplets combine to form creeks then rivers toward the lowest topographical locale.

Hydrological Cycle

Water taken from the cycle

Percolation occurs when water passes into another layer of medium like soil layers or caverns. As water infiltrates through soil and rock, pollution is filtered out. Consequently aquifers are valued water sources. [ I cannot understand why counties permit the intermingling of subterranean layers by fracking to dislodge natural gas.]

Sublimation tends to occur in snow covered mountains in spring when temperatures warm the ice and snow into water vapor.

Water that has infiltrated the root system of plants is taken up to assist photosynthesis and cellular respiration, then release water vapor from the underside of their leaves by a process of transpiration. Water is also taken up by animals for cellular respiration and released from the body through urination, exhalation and sweat.

Transfer of minerals

Freshwater descending through the water shed erodes and carries downstream materials from the edges and bottom of the stream. Those natural materials can be particles of soil, decaying plant or animal parts or unnatural chemicals or waste. Storms increase the accumulation of pollution into waterways.

The Special Properties of Water

Collectively they make water unique. One oxygen and two hydrogen atoms satisfy each other’s electronic potential to bond in the Y configuration. Some say it looks like a head with ears, but the diagram below shows the balance ionic charge (polarity) and the angles of attraction allow the molecule to behave like a magnet. The oxygen end (negative) attracts positively charged atom or molecules, and the Hydrogen end (positive) attracts negatively charged atoms and molecules. This bipolar attraction allows water to be an effective solvent.

Property Water Molecule Bonding from

Water will dissolve salts like NaCl, and glues like gelatin. The negative (oxygen) side of water molecule will lightly bond with the positive (hydrogen) side of other water molecule. These are called hydrogen bonds which cause water molecules to stick together and in the liquid state give water its surface tension.

Strider insect on water from Penn. State Uni.

This attraction referred to as cohesion allows water to flow through plant tissue and blood vessels by capillary action. At the surface of a vessel or drop water will appear to be curved or dome shaped.

Water can exist in three states at relatively normal conditions. A liquid at room temperature because of the hydrogen bonds previously mentioned. They continually break and form with other water molecules as the water moves.

Ice is formed, when water is cooled below 0o Celsius with average air pressure at sea level. Water as a gaseous vapor can turn directly into a solid. Frost forms from the water vapor in the air. Water molecules arrange with hexagonal crystals in solid ice, which takes up more space than very cold water where the molecules are tightly packed. Ice partially floats because it is slightly less dense than the cold water surrounding it. Consequently water expands on freezing and tends to freeze from the top down.

Water vapor is the gaseous form also known as aqueous vapor. It is lighter (less dense) than air, so it rests above the atmosphere with the other ‘greenhouse’ gases like methane and carbon dioxide, and provides an insulating effect on the atmosphere. Tropical areas with high humidity will experience warm nights as aqueous vapor prevents the heat of the day to escape. In cold air aqueous vapor is quickly condensed into fog or mist or can form dew or frost on the ground. If all the Earth’s water vapor were condensed the surface of the planet would be covered by one inch of water.

Movement of Water

Condensation is the change from gaseous vapor to liquid droplets. Rain drops or snowflakes can be airborne we see in clouds.

Pressure can also activate condensation. Contact with cold surfaces an initiate condensation to liquid.

Precipitation in the atmosphere occurs when it is saturated with water vapor which then condenses and into drops heavy enough to gravitate to Earth’s surface. Saturation can be from the addition of more vapor or cooling in the air.

Fresh water annually on Earth’s surface amounts to 500,000 cubic kilometers (km3), unfortunately 395,000 km3 falls onto our oceans. Note that rain evaporated from the already existing water sources.

Although the rain may have been pure initially but if its fall path goes through other substances in the atmosphere like, ammonium, nitrogen and sulphur it may form ‘acidic rain’.

Evaporation is the transformation of liquid water to aqueous vapor. The transfer requires an amount of energy (heat) which is used, called evaporative cooling. When water evaporates from open bodies of water like a dam, the depletion rate, measured annually can be as high as 120 inches depth. Evaporation leaves behind substances which have entered the water sources like polluting chemicals, and may render them in toxic concentrations in those open reservoirs.  Transpiration is how plants release water vapor from their leaves mainly and also stems, flowers and roots. A mature large tree may lose hundreds of gallons of water in a day which is up to 90 percent of the water absorbed through its roots. The under surface of leaves which are dotted with pores called stoma, which give off water vapor are bounded by guard cells that open and close the openings.[14]

Botanists have measured how much water a plant requires to grow, as an example cropping plants transpire from 200 to 1,000 litres of water (up to 1,000 kilograms) for every kilogram of dry material they produce, useful knowledge in arid regions.

Useful for us to know is that fresh water cannot just appear from the skies. The same water that occupied the surface and atmosphere of our planet millions of years ago is the water we see covering Earth today.

Underground Water Resources

This map of the United States shows the different types and locations of aquifers which provide half of U.S. drinking water and also water to agriculture, industry and the environment. Over 75 years drilling and pumping has dramatically reduced the quantity held within underground aquifers.

Aquifers in mainland United States

Libyas Aquifers

An aquifer is an underground geologic unit that is saturated with water that has sufficient permeability to yield that water to wells. A misconception exists that an aquifer is simply a large underground lake sandwiched between rock at both its top and bottom. This only exists in limestone caverns. The diagram below represents two different types of geologic materials, with different aquifer properties. As you can imagine, the well-sorted material allows water to move quickly through it (larger pore space), while the poorly sorted material requires a bit more energy and time for water to travel through it (see diagram below).[15]

Geology of Libya – Source Colorado Geological Survey

This study is to examine the physico-chemical quality of the Libyan Murzuq groundwater, to find the extent of its pollution and compare the quality standards for drinking water. Samples from 13 boreholes and the water wells of Sabha, in the Libyian localities. The criteria studied were  temperature, conductivity, salinity, acidity – alkalinity and hardness. The total dissolved solids (TDS) including presence of; Aluminum, Fluorine, Potassium, Sodium, Calcium, Magnesium, Iron, Copper, Manganese, Chloride, Sulfate, Silica, Nitrates, Nitrites, Ammonium, Ammonia, Nitrogen, Bicarbonate, Phosphate, Calcium Carbonate. Analysis showed that the groundwater of Murzuq was within the limits of Libyan Standards. However, some elements’ analysis showed high conductivity and concentrations of; TDS, Potassium, Sodium, Iron, Copper, Chloride, and Manganese. Questions persist to decide whether to limit the use of those waters for drinking.

Salt Water

Fresh water only accounts for 2.5 percent of the Earth’s total water, which leaves 97.5 percent of our water occupying 71 percent of the Earth’s surface. Even now some underground water reserves are highly brackish. Most of New Mexico’s underground water requires treatment for its saline concentrations.[17]

Earth’s Surfaces

Desalination of water

Two common methods of removing salt and impurities from water are forced distillation and reverse osmosis.

Forced distillation is the heating of the water until it evaporates then collected and condensed to liquid. The contaminant elements need to be physically separated from the water vapor by a filtration or trapping.

Reverse osmosis pumps water through a membrane that selectively filters away the salt ions. A cheaper method than paying for the energy required to heat water to boiling point.

Forward osmosis is more effective than reverse osmosis, it uses the movement of water molecules through a membrane into a ‘draw solution’. The draw solution is more concentrated in a special salt which is then evaporated using a low-grade heat.

Carbon nanotubes positioned in an impervious membrane restricts water flow through the tubes where an electric charge is applied that repels the positively charged salt molecules in sea water. The neutrally charged water molecules can pass through the tubes without the salt. This process requires relatively low pressure pumping. (I don’t know what happens to the negatively charged chloride ions, hopefully they are attracted to the electric charge and hold to the tube charged surface?) Biomimetics as the name suggests mimics the live cell membrane called aquaporin, a protein that conducts water in and out of other cells. The aquaporin like nano devise applies a positive charge at the protein’s aperture which repels the salt molecules.

Design elements and water flow in the synthetic mangrove

Capillary-driven desalination in a synthetic mangrove, Yunkun Wang, Jongho Lee, Jay R. Werber, Menachem Elimelech, Science Advances  21 Feb 2020: Vol. 6, no. 8, eaax5253 DOI: 10.1126/sciadv.aax5253 LINK

The schematic diagrams show the mangrove tree (left), the synthetic mangrove device (right), and their water transport mechanisms (center insets). In natural mangroves, capillary pressure created by evaporation into substomatal cavities (top left inset) brings about upward water transport through xylem channels (middle left inset) and desalination by aquaporin water channels in root cell membranes, which exclude salt from saline water in the soil (bottom left inset). The highly negative pressure in the root, Proot, overcomes the osmotic pressure of the saline water (πo), which enables water uptake through the root filtration system (i.e., Proot − πroot < Po − πo). The synthetic mangrove as shown comprises a nanoporous AAO membrane, a silica frit, and an RO membrane, mimicking the leaf, stem, and root of natural mangrove trees, respectively. Negative capillary pressure in the nanopores of the AAO membrane (top right inset) is the driving force for water transport through the silica frit (middle right inset) and desalination of saline water by a semipermeable RO membrane (bottom right inset). Hydrogel membranes are also used as leaves. Membranes were sealed using rubber O-rings, shown in black. Magnetic stirring is used to enhance mixing of the saline feed water and minimize concentration polarization at the membrane surface. Pleaf and Proot, xylem sap pressure at the leaf and root, respectively; Po, pressure in the soil or feed water; πroot, osmotic pressure of xylem sap at the root; πo, osmotic pressure of soil or feed water (~25 bar for seawater); γ, water surface tension; θ, water contact angle on nanopore wall; dp, nanopore diameter.

Water purification

Yellow Iris located in ‘treatment pond’.

The yellow iris (I. pseudacorus) is often used in water purification. The roots are usually planted in a substrate (e.g. lava-stone) in a reedbed-setup. The roots then improve water quality by consuming nutrient pollutants, such as from agricultural runoff. This highly aggressive grower is now considered a noxious weed and banned in some states of the US where it is found clogging natural waterways.

Groundwater of Egypt

Groundwater of Egypt: “an environmental overview” pub 12 Sept 2007

M. R. El Tahlawi, A. A. Farrag & S. S. Ahmed 

Although Egypt has the great Nile River, which is the main supply of water, Egypt’s water is limited to 55.5 billion m3 per annum. Owing to the rapid growth of the population and the increasing consumption of water in agriculture, industry, domestic use, etc., it is expected that Egypt will rely to some extent on groundwater to develop the new projects such as Tushka in Upper Egypt and East Oweinat. Issues related to groundwater in Egypt are identified with the common geological features associated with formation of the aquifers and demonstrating the location of the main resources of groundwater, followed by the main objective of this paper, which is addressing the environmental issues related to groundwater in Egypt. Several studies have been reviewed and personal communication made with the authorities to introduce this work and provide an overview of the groundwater quality problems in Egypt with examples from different parts of the country.

High Naturally Occurring Radioactivity from Fossil Groundwater in the Middle East

High levels of naturally occurring and carcinogenic radium isotopes have been measured in low-saline and oxic groundwater from the Rum Group of the Disi sandstone aquifer in Jordan. The combined 228Ra and 226Ra activities are up to 2000% higher than international drinking water standards. Analyses of the host sandstone aquifer rocks show 228Ra and 226Ra activities and ratios that are consistent with previous reports of sandstone rocks from different parts of the world.

Recognizing the vast uses of water in human life, the presence of α and β particles emitting radionuclides in groundwater of northern Saudi Arabia has been evaluated as a means of water quality assessment of the region. A liquid scintillation counting technique was used to determine the gross α/β, and 228Ra radioactivities in water samples, while the radioactivity concentrations of 234,238U and 226Ra were determined using alpha spectrometry after the separation process. Present results show that all water samples contain a higher level of gross α and β radioactivity than the WHO recommended limits; the average gross α activity is about 7 times greater than the limit value of 0.5 Bq L-1, while the average gross β activity value is about 3.5 times greater than the limit value of 1 Bq L-1. Correlations of TDS and pH with gross α and β radioactivity in the studied samples were investigated

Groundwater availability and water demand sustainability over the upper mega aquifers of Arabian Peninsula and west region of Iraq.  pub 8 Jan 2020. Salih Muhammad Awadh, Heba Al-Mimar & Zaher Mundher Yaseen

The current research is devoted to highlight the past, present and future status of groundwater characteristics over the Arabian Peninsula (AP) and west region of Iraq. The Umm er Radhuma, Rus Dammam and Neogene deposits are the major hydrostratigraphic units supplying the main groundwater resources in the AP. Water shortage is still a major problem for many countries in the world, including oil-producing countries such as Iraq, Saudi Arabia (SA), the United Arab Emirates (UAE), Qatar, Oman and Bahrain. The withdrawal of groundwater has been reflected in salinization of agricultural soils, leading to an increase in high-cost technologies such as desalination of seawater to provide suitable water for diverse sectors. Hence, the use of seawater desalination as a major source of water is unavoidable, and country development requires the use of renewable energy as protection of the environment. The need to conserve and use groundwater resources efficiently is highly essential owing to the fact that it is the only natural source of water in such developing countries of global importance. The review comprises various essential components related to groundwater variability including the hydrogeological aspects, climate change, drawdown and abstraction, rainwater harvesting, desertification and population increment.

Transboundary Water and Transboundary Aquifers in the Middle East: Opportunities for Sharing a Precious Resource Published 2010

R. Klingbeil, M. Alhamdi

Surface and groundwater resources in the Middle East are to a large extent transboundary. While much attention is given to the surface water and river courses crossing national boundaries in the region little has been achieved in understanding the sometimes hydrogeological complex transboundary aquifer systems. Much political attention is given to the rivers Euphrates, Tigris, Jordan and Nile as they connect Arab and non Arab countries. However, also between the Arab countries surface and groundwater crosses political boundaries and only few regional organizations address the need for improved internal Arab cooperation on shared water resources. An overview of confirmed and potential transboundary shared surface water and aquifers between ESCWA member countries and between ESCWA member countries and non member countries will be presented. Often detailed hydrogeological knowledge is still limited at national or trans-national level on the individual transboundary shared aquifer, some bilateral or multilateral cooperation between riparians (water course and aquifer states) have been taken place and are taking place in the region. In most cases the principles underlying the UN 1997 Convention on the Law of the Non-navigational Uses of International Watercourses and the UN General Assembly 2008 Resolution on the Law of Transboundary Aquifers as well as basic principles of IWRM applied in a transboundary context are already considered to some extend as guidance for individual cooperation mechanisms that may eventually develop into bilateral, multilateral or regional agreements and/or conventions. ESCWA supports its member countries towards bilateral as well as regional cooperation mechanisms through a number of tools such as the cooperation through the Committee of Water Resources and activities of the ESCWA work plan, shared water resources assessments and guidance, development of negotiation skills, dispute resolution and regional advisory services responding to specific requests from member countries.

Raising the Dead Sea

Dead Sea Level evolution since 1800.

The project to channel water from the Red Sea to the Dead Sea has fascinated people for the past one hundred and fifty years. It was brought back to the fore in 2005 by the three neighboring countries: Jordan, Israel and the Palestinian Authority. The stated goals are to halt the decline of the Dead Sea (fig. above) and to save it from environmental damage (fig. below), to desalinate water and produce affordable energy for all three countries, creating a symbol of peace through a tripartite cooperation (World Bank, 2005). However, the project, at a cost of over $11 billion over twenty years, requires regional stability that is far from being achieved.


Our great luminary, the Sun powers its emissions by the fusion of hydrogen where the two hydrogen atoms combine, or fuse to become a helium atom. The fusion of the two hydrogen atoms into a helium atom releases energy. The hydrogen nucleus components of neutrons and protons combine to form the helium nucleus. The energy required to bind the two hydrogen atoms is more than the strong nuclear force needed to hold the helium atom together. Einstein applied the term ‘missing mass’ also called mass defect to describe the energy released when the new nucleus was formed.

When hydrogen is burnt for power, i.e. combined with oxygen the product is water (unless it is burnt in air then nitrogen oxides are also produced). But coal and petrol produces carbon dioxide CO2, carbon monoxide CO, and a host of ‘nasties ‘  like; oxides of sulphur and nitrogen which dissolve in rain water and become acidic.

Carbon based fuels have been compressed in the Earth’s crust for millions of years, now in a hundred years we are releasing their burn by-products into our own air we breathe.

Photo synthesis the process plants use to power their conversion of water H2O and carbon dioxide CO2 into oxygen O2 and sugar CH2O is explained in detail in part3 Energy.

Ah but oil companies make a lot of money selling carbon based fuels to us. And the sun does not shine at night.

Hydrogen is the most common fuel source in our universe. Our sun uses 500 million metric tons each second. [1]

What are the products from burning hydrogen? Is it just water?

Do we have to change our engine technologies to burn hydrogen? Yes our atmosphere is 79% nitrogen.

Who processes hydrogen for sale? These are questions that come to my mind.

scheme of a fuel cell by Sergey Merkulov

The fuel cell

Hydrogen consumed in a fuel cell, produces electric energy the by driving a turbine just like a power station. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like hydro turbine, solar and wind. Hydrogen can be stored so it can transfer the energy produced from other sources. The fuel cell has become a favored option for all transportation and electricity generation applications.[2]

The hydrogen clean fuel can be produced by a number of diverse methods. The most economical are natural gas reforming (a thermal process), and electrolysis. Other methods are solar-driven and biological processes.

Making Hydrogen


A high temperature processes to produce hydrogen involves a process of steam reacts with a hydrocarbon fuel to produce hydrogen. Many hydrocarbon fuels can be reformed to produce hydrogen, including natural gas, diesel, renewable liquid fuels, gasified coal, or gasified biomass. Today, about 95% of all hydrogen is produced from steam reforming of relatively low-cost natural gas.

Natural gas contains methane (CH4) that can be used to produce hydrogen with thermal processes, such as steam-methane reformation and partial oxidation.

Steam-methane reforming

 Methane reacts with steam (7000 to 10000C) under pressure (3–25 bar) in the presence of a catalyst to produce hydrogen, carbon monoxide, and a relatively small amount of carbon dioxide. Heat and pressure must be supplied to the process for the reaction to proceed. A further process of water-gas shift is carried out.

Steam-methane reforming reaction
CH4 + H2O (+ heat) → CO + 3H2

Water-gas shift reaction

The produced carbon monoxide is mixed with more steam and a catalyst to produce carbon dioxide and more hydrogen. Then a final process step called “pressure-swing adsorption,” carbon dioxide and other impurities are removed from the gas stream, leaving essentially pure hydrogen.

Water-gas shift reaction
CO + H2O → CO2 + H2 (+ small amount of heat)

Partial Oxidation

Where natural gas is reacted with air, there is insufficient oxygen to convert the methane and other hydrocarbons completely to carbon dioxide and water. The resultant produces primarily hydrogen and carbon monoxide, nitrogen and a relatively small amount of carbon dioxide and other compounds.

Then in the water-gas shift reaction, the carbon monoxide reacts with water to form carbon dioxide and more hydrogen.

In partial oxidation heat is given off. This method is faster than steam reforming and requires a smaller reactor vessel. However this process initially produces less hydrogen per unit of the input fuel than is obtained by steam reforming of the same fuel.

Partial oxidation of methane reaction
CH4 + ½O2 → CO + 2H2 (+ heat)

Water-gas shift reaction
CO + H2O → CO2 + H2 (+ small amount of heat)

Fuel Cell Electric Vehicle FCEV

Petroleum consumption and emissions from FCEVs are lower than for gasoline-powered internal combustion engine vehicles. Water vapor is said to be the only exhaust product. If you include the production of hydrogen from natural gas, delivery and storage logistics, then atmospheric emissions are halved and petroleum consumption is only 10 percent of petrol driven vehicles.

Water can be separated into oxygen and hydrogen through a process called electrolysis. Electrolytic processes take place in an ‘electrolyzer’, which functions much like a fuel cell in reverse—instead of using the energy of a hydrogen molecule, like a fuel cell does, an electrolyzer creates hydrogen and oxygen from water molecules.[3]

Hydrogen Production: Electrolysis Electrolysis is a promising option for hydrogen production from renewable resources. Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This reaction takes place in a unit called an electrolyzer which is well-suited for small-scale distributed hydrogen production to large-scale, central production facilities that could be link into a system of other non-greenhouse-gas-emitting forms of electricity production.[4]

Learn more about electrolytic hydrogen production.

How Does it Work?

Like fuel cells, electrolyzers consist of an anode and a cathode separated by an electrolyte. Different electrolyzers function in slightly different ways, mainly due to the different type of electrolyte material involved.

This Process is being considered because hydrogen produced via electrolysis can result in zero greenhouse gas emissions, depending on the source of the electricity used. The source of the required electricity—including its cost and efficiency, as well as emissions resulting from electricity generation—must be considered when evaluating the benefits and economic viability of hydrogen production via electrolysis.

Amalgamation with renewable electricity generation
Hydrogen production via electrolysis could be working when excess electricity is produced from wind farms or solar installations. Instead of curtailing the electricity as is commonly done, it is possible to use this excess electricity to produce hydrogen through electrolysis. The hydrogen in storage is available to produce electricity when wind or sun is not available.

SOLAR-POWERED Hydrogen Production

Sunlight as the driver for hydrogen production has a few processes, including photo-biological, photo-electro-chemical, and solar-thermo-chemical.

Photo-biological processes use the natural photosynthetic activity of bacteria and green algae to produce hydrogen.

Photo-electro-chemical processes use specialized semiconductors to separate water into hydrogen and oxygen.

 Solar-thermo-chemical hydrogen production uses concentrated solar power to drive water splitting reactions often along with other species such as metal oxides.


Biological processes use microbes such as bacteria and microalgae and can produce hydrogen through biological reactions. In microbial biomass conversion, the microbes break down organic matter like biomass or wastewater to produce hydrogen, while in photo-biological processes the microbes use sunlight as the energy source.

Microbial hydrogen production

Microorganisms have the ability to consume and digest biomass and release hydrogen referred to as microbial biomass conversion processes. Research in biomass conversion could result in commercial-scale systems becoming suitable for local distribution, semi-central, or central hydrogen production scales, depending on the organisms (feedstock) used.[5]

Microorganisms, such as bacteria, break down organic matter to produce hydrogen. The organic matter can be raw biomass sources like refined sugars, corn stover*, and even wastewater. Because no light is required, these methods are sometimes called “dark fermentation” methods.

(*Stover consists of the leaves, stalks, and cobs of maize plants left in a field after harvest. Such stover makes up about half of the yield of a corn crop and is similar to straw from other cereal grasses.)

Photobiological hydrogen production

Microorganisms —such as green microalgae or cyanobacteria—together with sunlight split water into oxygen and hydrogen ions. Challenges for this pathway include low rates of hydrogen production and the fact that splitting water also produces oxygen, which quickly inhibits the hydrogen production reaction and can be a safety issue when mixed with hydrogen in certain concentrations.

Some photosynthetic microbes use sunlight as the driver to break down organic matter, releasing hydrogen, this is known as photofermentation. The algae and bacteria could be grown in water that cannot be used for drinking or for agriculture, and could potentially even use wastewater. Its challenges include a very low hydrogen production rate and low solar-to-hydrogen efficiency, making it a commercially unviable for hydrogen production. In time photobiological production may provide economical hydrogen production from sunlight with low- to net-zero carbon emissions. [6]

Photobiological hydrogen production from cyanobacteria Anaebena variabilis

The objective of the Samueli Engineering UCLA project is to perform a comprehensive study to simultaneously mitigate carbon dioxide and produce hydrogen. It offers a cheap, efficient, scalable, autonomous, and reliable system for producing hydrogen from microbial consumption of carbon dioxide and absorption of solar light.[7]

  • Approximately 5 mm in diameter and 100 mm long.
  • Their genome has been sequenced.

Photobioreactor Description and Operation

The UCLA Engineering project has designed, built, and now are operating a fully instrumented photobioreactor. The following measurements are systematically performed:[8]

Incident light intensity gas in-flow rate-Temperature – pH, dissolved O2 – nitrates-, ammonia- out-flow rate, pressure, -gas composition (O2, H2, CO2, and N2 )

The photobioreactor is operated using two stages. Switching from Stage 1 to Stage 2 takes place when the nitrate concentrations in the liquid phase vanishes.

Stage 1: Carbon Dioxide Consumption and Bacterial Growth

  • presence of nitrates and nitrogen.
  • sparging with 95% air and 5% CO2 at 170 mL/min.
  • irradiance: 65-75 umol/m2/s.

Stage 2: Hydrogen Production

  • absence of nitrates and nitrogen.
  • sparging with pure Argon at 45 mL/min.
  • irradiance: 150 umol/m2/.


  • The growth phase lasted 110 hours.
  • The H2 production phase lasted more than a week.
  • The light to hydrogen energy conversion efficiency reached 0.5%.
  • The light to biomass energy conversion efficiency was 4.7%.

Solar Thermochemical Processes

Thermochemical water splitting uses high energy chemical reactions to produce hydrogen and oxygen from water. This is a long-term technology pathway, with potentially low or no greenhouse gas emissions.

The temperatures needed to split water molecules into their atomic constituents are 500° to 2,000°C. The heat could applied from either solar installations or the waste heat of nuclear power the reactions.

The chemicals used in the process are retained within each cycle, a closed loop that consumes only water and produces hydrogen and oxygen.[9]

At the heart of these water splitting reactors is a thermo- chemical cycle of oxidation and reduction of cerium oxide particles

Reduction: 2Ce(IV)O2  –> Ce(III)2O3 + ½ O2

Oxidation: Ce(III) 2O3 + H2O ® 2Ce(IV)O2 + H2

Hydrolysis: 2CuCl2 + H2O –> 2 Cu2OCl2 + 2HCl

Electrolysis: 2CuCl + 2HCl + (electric input) –> 2CuCl2 + H2

Net Reaction: H2O –>  O2 + H2

Thermochemical and Hybrid Water Splitting Technologies

Sulphur is a redox active element in the two step cycle.

Photo-Electro-Chemical Water Splitting: Hydrogen Production

Using photo-electro-chemical (PEC) materials in specialized semiconductors the energy in light causes the molecules in water to break their covalent bonds and separate into hydrogen and oxygen.

This is a long-term approach with the aim of eliminating greenhouse gas emissions.

The semiconductor materials used in the PEC process are similar to those used in photovoltaic solar electricity generation, but for PEC applications the semiconductor is immersed in a water-based electrolyte, where sunlight energizes the water-splitting process.  The National Renewable Energy Laboratory provides a demonstration.

Hydrogen Fuel Cell

Hydrogen and Oxygen Fuel cell by Fouad A. Saad. Shutterstock

Inside a fuel cell

A fuel cell works much like an electric battery, converting chemical energy into electrical energy using the movement of charged hydrogen ions across an electrolyte membrane to generate current. There they recombine with oxygen to produce water – a fuel cell’s only emission, alongside hot air.

Although less efficient than electric batteries, today’s fuel cells compare favourably with internal combustion engine technology, which converts fuel into kinetic energy at roughly 25 per cent efficiency. A fuel cell, by contrast, can mix hydrogen with air to produce electricity at up to 60 per cent efficiency.

FCEVs also present relatively low barriers to entry in terms of societal changes, as they operate and perform similarly to conventional vehicles, refuelling at stations in minutes and driving for 500 to 600 kilometres on a single tank, all with no harmful emissions.

Making hydrogen

The hydrogen fuel itself can be produced with ever-increasing cost-effectiveness through electrolysis, by splitting water into its constituent hydrogen and oxygen atoms. This generates two useful gases and, when powered by green energy, makes hydrogen production a carbon-neutral enterprise.

At present, however, just 2 per cent of the 600 billion cubic meters of hydrogen manufactured each year around the world is produced by water electrolysis, while 98 per cent is produced from natural gas, with carbon dioxide as a by-product.

More than 90 per cent of this hydrogen is used as a building block for fertilisers or is consumed within the oil, refining and wider petrochemicals industry.[15]

The development of the hydrogen economy, therefore, relies on government investment in the initial phases. Investment in both hydrogen production and distribution infrastructure is needed, alongside the renewable power projects required to supply carbon-neutral energy.

The Toyota Mirai, the world’s most popular FCEV (pictured earlier), was launched in the UAE back in October 2017, when the country’s first hydrogen station was opened by a partnership of local Toyota distributor Al-Futtaim Motors, Abu Dhabi’s Masdar City and France’s Air Liquide.

The hydrogen economy is taking off in Japan, where 100 refuelling stations have already been established, and the government aims to have 800,000 FCEVs on the road by 2030, alongside a 90 per cent reduction in the cost of hydrogen by 2050.

Electric competition

Recent funding into the research and development of electric vehicle (EV) technology has vastly outstripped that of water electrolysis and fuel cell technology.

This situation has been driven by the rapid development of more efficient and cost-effective electric battery technology, lowering the potential costs of electrified transport systems.

EV and hybrid vehicles have an additional edge in terms of overall energy efficiency. Batteries now lose only about 17 per cent of the initial input of electrical energy through inefficiencies when charging and discharging, while the cycle of using electrical energy to split water into its constituent atoms and recombining hydrogen with air inside a fuel cell wastes more than 50 per cent.

Installing EV charging points at key locations, such as at facility car parks, is also simpler and promises governments more immediate and obvious returns than the more complex task of establishing hydrogen distribution infrastructure.

The upshot of this is that, to date, while EV and plug-in hybrid vehicle sales number in the millions, the most popular model of FCEV, the Toyota Mirai, has sold just 5,000 units.

Transport niche

FCEV technology could be especially useful for commercial applications where bulkier vehicles need to travel long distances, carry heavy loads and refuel with minimal downtime.

Trials in hydrogen have been conducted on everything from public buses and forklifts to trains, planes and boats. For such applications, especially with the larger craft, electric batteries would need to be problematically large. Hydrogen could also be used to replace some of the compressed natural gas used in domestic applications, with minimal changes to existing infrastructure.

A study by Swansea University in the UK found that up to 30 per cent of domestic gas could be safely replaced with hydrogen, thereby reducing carbon emissions by 18 per cent, with no changes to existing infrastructure.

In Europe, the ‘EUTurbines’ group of manufacturers has pledged to make their gas turbines run on up to 20 per cent hydrogen gas by 2020, and develop turbine technology to allow all manufactured units to run, or be retrofitted to run, on 100 per cent hydrogen gas, and be carbon-neutral, by 2030.

Rising efficiencies

Globally, the cost of hydrogen is already coming down, partly in line with the fall in the cost of renewable energy, but also due to improvements in water electrolysis and hydrogen fuel cell technology.

The Paris-based International Energy Agency expects the cost of producing hydrogen to fall by a further 30 per cent by 2030, but the rapid reduction in the cost of recent photovoltaic solar energy projects in the Middle East could mean the local cost of commercially producing hydrogen will fall even faster. As investment in hydrogen infrastructure grows and net costs continue to fall, the hydrogen economy could prove to be an indispensable tool in the transition away from hydrocarbons.

Mauritus Oil Spill

Oil spill Mauritus, NBC New

The volunteers have ignored a government order to leave the clean-up operation to local officials, potentially risking a fine or other punishment. NGOs asked volunteers on Tuesday not to risk their health cleaning up the oil on the coast but to concentrate on boom-making instead.

High winds and waves are pounding the Japanese bulk carrier, which is showing signs of breaking up and dumping its remaining cargo into the waters surrounding the postcard-perfect island off the east coast of Africa.

Oil spill cleanup Mauritius, Ben Pillay, NBC News

Nearly 2,000 metric tons of oil, diesel and petroleum lubricants could inundate the lagoon if the Wakashio breaks apart, and experts believe it’s a matter of hours.

“The situation is very critical. Cracks have expanded over the course of the day,” said Dr. Vassen Kauppaymuthoo, the island’s premier oceanographer.

“The situation’s about to get 10 times worse. It’ll be a major catastrophe,” he said.

The oil is traveling up the coast, Kauppaymuthoo told NBC News, which could lead to huge stretches of lagoon being affected.

“It’ll take decades to rehabilitate the lagoon, and it’ll never be as it was before the spill. We have thousand-year-old coral here, protected species in our waters,” he added.1

Stored hydrogen


Stored hydrogen can also be used to run heavy duty mobility and everyday fuel cell vehicles. By recombining hydrogen and oxygen, a flow of electrons is created that result in electricity that can be used to run electric engines.

Hydrogen + Oxygen = Electricity + Water Vapor

Pic: pictures>science energy>hydrogen> Hydrogen and oxygen fuel cell , by Fouad A. Saad
reactions:  Cathode: O2 + 4H+ + 4e → 2H2O    Anode: 2H2 → 4H+ + 4e    Overall: 2H2 + O2 → 2H2O

A fuel cell is a device that converts chemical potential energy (energy stored in molecular bonds) into electrical energy. A PEM (Proton Exchange Membrane) cell uses hydrogen gas (H2) and oxygen gas (O2) as fuel. The products of the reaction in the cell are water, electricity, and heat. This is a big improvement over internal combustion engines, coal burning power plants, and nuclear power plants, all of which produce harmful by-products.

Since O2 is readily available in the atmosphere, we only need to supply the fuel cell with H2 which can come from an electrolysis process (see Alkaline electrolysis or PEM electrolysis).

The four basic elements of a PEM Fuel Cell:

The anode, the negative post of the fuel cell, has several jobs. It conducts the electrons that are freed from the hydrogen molecules so that they can be used in an external circuit. It has channels etched into it that disperse the hydrogen gas equally over the surface of the catalyst.

The cathode, the positive post of the fuel cell, has channels etched into it that distribute the oxygen to the surface of the catalyst. It also conducts the electrons back from the external circuit to the catalyst, where they can recombine with the hydrogen ions and oxygen to form water.

The electrolyte is the proton exchange membrane. This specially treated material, which looks something like ordinary kitchen plastic wrap, only conducts positively charged ions. The membrane blocks electrons. For a PEMFC, the membrane must be hydrated in order to function and remain stable.

The catalyst is a special material that facilitates the reaction of oxygen and hydrogen. It is usually made of platinum nanoparticles very thinly coated onto carbon paper or cloth. The catalyst is rough and porous so that the maximum surface area of the platinum can be exposed to the hydrogen or oxygen. The platinum-coated side of the catalyst faces the PEM.

Advantages of the technology:

  • By converting chemical potential energy directly into electrical energy, fuel cells avoid the “thermal bottleneck” (a consequence of the 2nd law of thermodynamics) and are thus inherently more efficient than combustion engines, which must first convert chemical potential energy into heat, and then mechanical work.
  • Direct emissions from a fuel cell vehicle are just water and a little heat. This is a huge improvement over the internal combustion engine’s litany of greenhouse gases.
  • Fuel cells have no moving parts. They are thus much more reliable than traditional engines.

Search for the Protein Sequence

The Office of Naval Research awarded a three year grant to the team at Washington University to investigate ‘layered nano-structures’  like the abalone shell infamous for its strength and resilience. Clement Furlong supervisor to Rich Humbert and leader of Medical Genetics stated ‘Once we sequence the protein we’ll have to find a way to produce lots of it’1.

Abalone mollusks raw with shell

Collecting it is hard on the abalone population and scraping the muscle out of its shell then processing it truncates the protein molecules or worse. Alternatively the familiar E. coli bacteria could be employed to manufacture the protein. We have it in our own gut. It has been used by bacteria, yeast, mold for making wine, brewing beer, leavening bread and culturing cheese. Bacteria is grown in vats to produce food additives, antibiotics, industrial chemicals, vitamins and more.

Insulin manufacture for example we take a human gene and splice it into E.coli. Then the E.coli-modified actually produces the insulin. In times gone tons of pork was processed to refine purified insulin2. Both hormone and protein, insulin is a sequence of 51 amino acids, differing from pork’s insulin in only one. By the 1970’s scientists were stringing together nucleic acids in arrangements to synthesize human genes including the insulin gene. A gene is a section of DNA with instructions to make a particular protein. Scientists inserted a synthesized gene into a small loop of a carrier DNA to guide the production of a protein.

The DNA ring needs to be inserted into an organism with the biological capabilities needed to assemble a protein. Researchers at Genetech announced in 1978 that they had a strain of E.coli bacteria produce the insulin protein by giving it a human gene2.

Escherichia coli also known as Ecoli bacteria health science concept by Ezume Images

Once the protein is sequenced, the dip-and-coat procedure for making nacre (abalone). From the protein template they will insert that DNA into E.coli. Then hope the E,coli follows the coded instructions in the template DNA to produce proteins to order in a bio-reactor supplied with water, food and air.

Fishing for templates

A key discovery in molecular biology is the procedure to find the gene or portion of the gene that is responsible for producing the required protein. The code for the protein that templates crystalline production is in the abalone’s cell, in a DNA segment. Finding it is the key.

The OLIGIO machine

To get the protein with the code we need; a seeker code that keys into the desired code can be made using a machine that links together a sequence of nucleotide molecules which are the elements of a DNA code. The oligio machine drips the adenine [A], the thymine [T], the guanine [G] or the cytosine [C] onto the carbon based chain to produce the coded seeker protein which will attach to the protein chain needed, referred to as the complimentary DNA [cDNA]. Nucleotide A will compliment T, and nucleotide C will compliment G. So the seeker protein will attach to a cDNA on a much longer protein chain. Then hopefully the whole protein is intact and more hopefully a compliant strain of E.coli will take the cDNA and produce the protein needed for the form work for the crystal.

Biolytic Dr. Oligo 192 : DNA – RNA Oligonucleotide Synthesizer

To determine whether the E,coli is producing the desired protein scientists use another biological probe – an antibody just like those produced by our immune system. Rather than inject ourselves with mollusk protein they use a rabbit to produce an antibody to attach and interfere with the mollusk protein. Instruments will identify where the antibodies are conglomerating. Then that cluster of E.coli can be distributed onto more dishes to grow their colonies of the desired protein.

The question arises will crystals grow as well on differing protein structures? Trial and testing will only answer that.

Using the natural method of growing crystals

Galen Stuckey of the department of Chemistry and Daniel Morse of the department of Molecular and Cellular Developmental Biology at the University of California found as the Washington team found that insoluble proteins congregated at the bottom of the beaker instead of going into solution and were not giving up their amino acid sequence. Stuckey and Morse determined they would make a protein analogue to stand in for the real abalone protein3.

First job was to get the analogue protein to stick to a surface that could support crystal growth. They chose Langmuir – Blodgett film4.

diagram: L – B film

With the aid of chemical, ‘hooks’ the protein sheet embeds into the fatty layer of B-L film. While negatively charged ‘pleats’ of the protein molecules hang down into the water creating landing sites for the ions of the crystal medium5.

Being able to arrange the placement of the nucleation sites Morse can basically direct what kind of crystal will grow crystals. Peter C. Rieke material scientist is trying to grow crystals on a thin film. Made in a laboratory, film called ‘self assemble monolayers (SAMS)6. Instead of being suspended on water they are coated onto glass slides. And the chemical charged groups are part of the film itself. The charge groups are positioned where they are functionally needed. The films are a mosaic of positive or negatively charged shapes that serve as landing sites for the ions from solution to attach and grow crystals.

Potentially different types of crystals could grow on the same film. The process is still two dimensional where as the mollusk’s build crystalline structures between the abalone’s body and its outer shell.

Rieke uses a polystyrene substrate, common plastic used for bottles and caps, it is a polymer analogous to the biopolymer the mollusks employ for nucleation. (More on nucleation see further reading) He has tried the old calcium carbonate, lead iodide, calcium iodate and iron oxide6. Application for crystalline structures are being considered for high specification components in vehicles, windows in lightweight electric cars, and coating for gearing where abrasion and corrosion resistant surface treatments are required. A two bath dipping process, first coat with the template protein the second the mineralized ionic crystal would revolutionize the coating technology from information storage to drive trains.

3D Crystal Containers

Single celled magneototactic bacteria produce perfect crystals wrapped in organic membrane. An example of a magnetic presence in a chemical reactor without the magnets clumping together, neutralizing themselves7. Ferritin is the protein that sequesters iron oxide in the human body, which prevents rust being in our cells.

He has made organic balloons of various shapes and has used jelly like polymer that can be inserted with minerals giving the hardness quality with the flexibility of the polymer7.

Resiliant materials are created constantly in living organisms, skin, tendons, blood, cellulose, a variety of adhesives. Organic compounds are based on carbon chain molecules. Life forms make them to order and the form definitely follows their function. There is no by product or residual waste, native life cannot afford extraneous consumption or energy.

Herbert Waite’s research while affiliated with University of California, Santa Barbara worked with mussels (Mytilus edulis ). The only response available to the sessile mussel Mytilus edulis in order to avoid predators or desiccation during aerial exposure is valve closure. The posterior adductor muscle is able to remain contracted for several days at low energy cost9. If you had tried to take one you would notice how hard they are to remove from their chosen location. M. edulis’ attachment is made up of tethers called byssus with discs on their ends called plaques they use to locate themselves in the tidal zone8.

Engineers have determined that if you want something to stay put in a wave battered coast by itself it needs to be of the order of 40 tonne. The M.edulis sends out a flesh tongue like extremity and creates a thread and plaque with adhesive tether called ‘byssus complex’. Glands secrete collagen protein (as in tendons) into a groove in the tongue that acts as a mold. The thread and plaque self assemble and harden in the groove and then a gland near the tip of the tongue squirts adhesive protein between the plaque and the surface of its residential site8. A few minutes is all it needs. The bi-valve can repeat the tethering to oppose the wave pressure. Then it can open its shell to allow filtering of the turbulent sea water to extract nutrients13. M.edulis produces an adhesive that can be applied in brine and bonds extremely well to any surface. Pushing its tongue onto the surface squeezing out water it then deposits a mucus seal around the edges of contact. Next the muscles in the tongue pull off the contact zone to form a cavity with partial vacuum (like a bell shaped suction cup). The thread and disc are cast then adhere to the surface10.

Mussel attached to surface by its Byssus components. from Silverman and Roberto 2007 Ref 28

We would make separate parts as we perceived the functions required and us an applicable glue (polymer sealant probably) to stick them on. The bi-valve now manufactures the solid foam disc (plaque) that is formed in the grooved mold from different proteins that squirt out of the cavity. It thickens to foam (like Styrofoam) which suits the characteristics a mussel would want in its foot (byssus), flexible and fracture resistant8.

The thread of M.edulis’ byssus is similar to our manufactured polymer entwined cord. Single fibres twisted or woven together to share a load on the whole cord, rope or cable. Herbert Waite when studying the byssus found not one collagen based protein but hundreds all slightly different in composition. Along the collagen chain each molecule has a section that is springy (like a tendon) and another section more rigid (like skin). The proportion of rigidity to spring depends on where the molecule is situated along the byssus thread. The molecular selection arrangement of M.edulis makes its byssus have more capacity in its properties than mono-molecular collagen10.

Modern manufacturing is riddled with fasteners, screws, bolts, rivets, anchors, ties and adhesives. Nature ‘blends gradients so that the fiber has no single vulnerable point’ Paul Calvert would say14.

The byssus of the mussel is like grissle but still food (protein) for any organism with voracious appetite. Fully aware of this M.edulis applies a clear sealant of yet another protein this time impervious to microbes. But not permanently so, the mussel will move on at will leaving its byssus. The protein sealant will breakdown in two to three years allowing the microbes to devour the protein morsel11,12. Again nature’s mussel waste is used. Our present petrochemical plastics are relatively indestructible. Yet they break into small chips and particles in sun light, yet they remain indigestible by organisms.

Plastic containers will remain in landfill and contaminate most habitats long after we have decayed. Consumer products that only need a short life cycle could be made from naturally grown materials like cellulose, silk, collagen, rubber or chitin (as in crab shells) and seal them with a resilient coating that does breakdown to digestible condition for microbes in land fill to consume and return the material to the food cycle.

The adhesive exuded by M.edulis has protein chains with molecular hooks that Velcro-like link onto similar molecules. The integrity of the molecular cross linking is fully achieved with the aid of a catalyst specific for that purpose. Just to recap the lowly mussel M.edulis forms its own fibre, plaque, adhesive and sealant.

Common mussel attached to shore by Jacob Campbell -unsplash

Companies are chopping up mussels, purifying the protein and using the mollusk’s protein to coat glass slides as a cell and tissue adhesive. I am reminded of the pearl diving industry of the Red Sea. Five hundred clams were collected and prized open for every natural (grit irritant) pearl collected. The mussel is a filter feeder so has little control about what it ingests. The same protein that forms the adhesive that glues its byssus to metal or rock or painted surfaces also adheres to the heavy metal particles M.edulis takes in. So when it leaves a site it leaves the byssus with its metal toxins behind.

We have the silk worm, cotton, wool for textiles, thread and yarn. And then there is spider web filament (silk) once used for drawing open flesh wounds to gather the skin lesions. Silk is collected by boiling the cocoon with the silk worm grub (pupae) inside to unravel the filament strands. Do we have factories of spiders fed on insects to issue extrusions of their super thread? They could deliver 30 meters at one shift.

Golden Orb Web Weaver Spider – by Stacey Ann Alberts.
“Ambushing its prey whilst dangling from its complex web of super strength and invisible death”

The golden orb weaver (Nephila clavipes) produces six fibers (silks) each each concocted in its own gland extruded through an individual spinneret15. Spiders perform various functions with their silk18; radiating webs with fine silks coated with glue, dense sticky sheets, invisible snares, a single strand with adhesive ball slung at its prey. Males impregnate pheromones onto their silks; some wrap the silk with sperm to be fertilized by the female, notorious for attacking their suitor and wrapping him into a silk sarcophagus. Some males impregnate their silk with an immobilizing agent16.

In some conditions inorganic materials will orderly combine with organic materials to form a rigid crystalline structure. In liquid state molecules will align in orientation but be fre to move location that can be called liquid crystal. An indication of crystal form in a material is its refractive index (R.I.). The RI of silk 17 is known but for spider silk it is much higher. The spider has the ability to combine different material types into one composite.

Spider silk has properties far exceeding those of steel, weight for weight five times the tensile strength. And five times the impact resistance of Kevlar as well as being more elastic than nylon (more on the unintended effects of Kevlar in Further reading). It also resist freezing becoming rigid so being less likely to break. Spider silk starts out at as liquid protein in a gland sack, water soluble before it is extruded through one of its 6 groups of nozzles (spinnerets) at the back of its abdomen15.

Spinnerets of a Wasp Spider by Kurt Hohenbichler

Christopher Vinney of Seattle postulates the proteins are grouped in balls with the water resistant amino acids on the molecular chain congregating at the center, with the water attracting amino acids on the circumference. Then when the protein balls are squeezed through the spiders’ nozzles the balls burst spreading the molecules out, giving them opportunity to realign. In this instance the water attracting molecules hooking on to each other in the linear form, and the water resistant amino molecules on the outside of the elongated clusters, giving the spider silk its water proof quality and linear strength19.

Randolph V. Lewis does not agree and strongly suggests the silk is a combination of at least two protein strains20.

Golden Orb web Spider on its web by Albie Venter

David L. Kaplan works on biomolecular materials at the Development and Engineering Center of Army Research at Natick, Massachusetts and has investigated the spider’s glandular proteins. The 9000 DNA sub units are repetitive and highly likely to be deleted and recombine when reproduced by good old E.coli.

His team synthesizes small proteins of the DNA with the oligio machine, duplicate them and stuck them together with an enzyme – ligases to make longer protein chains. After extensive cajoling E.coli accepted the synthesized DNA and the bacteria did produce the protein.

Note: MaSp1 or MaSp2: major ampullate spidroin 1 or 2; MiSp1 and 2: minor ampullate spidroin1 and 2; Flag: flagelliform protein21.

To design the fibre they need decipher which amino acid combinations deliver which physical characteristics. Randolph Lewis worked with the wild gene, the team from the University of Wyomng (UW) use genetic engineered probe to catch portions of the two proteins and then inset those gene fragments into E.coli for replication and dutifully proteins were expressed and even woven at a fibre20. But as yet they could not compete with spider silk thread.

In a collaborative project with the University of Notre Dame and Zhejiang University in China, UW researchers have genetically engineered silkworms to spin silk containing spider silk proteins. Those fibers are stronger than fibers normally spun by silkworms and almost as tough as spider silk22. It is only the golden orb (Nephila clavipes) they make reference of; there is most likely other spiders producing silks of different and possibly better properties yet to be identified, their habitat being slashed and burnt.

Nucleation: Crystallography

Written by The Editors of Encyclopaedia Britannica

Nucleation, the initial process that occurs in the formation of a crystal from a solution, a liquid, or a vapour, in which a small number of ions, atoms, or molecules become arranged in a pattern characteristic of a crystalline solid, forming a site upon which additional particles are deposited as the crystal grows.

Ice in lakes and rivers, a sheet or stretch of ice forming on the surface of lakes and rivers when the temperature drops below freezing (0° C [32° F]). The nature of the ice formations may be as simple as a floating layer that gradually thickens, or it may be extremely complex, particularly when the water is fast-flowing. 

Kevlar manufacture is not environmentally friendly is to understate its effects. Polyaramid kevlar is derived from petroleum based chemicals thrown into concentrated sulphuric acid and subjected to considerable temperature and pressure to convert it into liquid state crystal. More pressure is applied to order their line up as they are extruded. The expenditure of energy is exorbitant and the by-products and waste are unmentionably poisonous.

Why design from nature? Part 4: CREATING

Making the Built Environment

Manufacture of paper, plastics, chemicals and metals produce 71% of toxic emissions in the U.S.1 Materials were produced by nature; timber, rock, clay, reeds for thatch, hide, wool, silk, and bone. Then man began to make things and it labeled the times; the Stone age, the Bronze age, the Iron age, fantastic plastic age, and now the age of silicon.

Nature has four laws for manufacture.

  1. Life friendly process
  2. Ordered hierarchy in structure.
  3. The elements self assemble
  4. Template crystalline forms with proteins.

For millennia we made things out of natural materials and once they out lived their useful life it mattered little if they were discarded to decay and absorb into another life. The modern synthetic materials have a hard act to follow. The iniquitous prizing open of an abalone shell reveals a mother of pearl lining on a substance twice as tough as any high tech ceramic. A spider’s web weight for weight is four times stronger than steel. The adhesion a mussel exudes to fasten itself to rock or reef in salt water needs no preparation and sticks to anything. Rhinoceros horn is capable of repairing itself yet contains no living cells. Add to that list bone, wood, skin, wool, tusk, antler, tendon and heart muscle. I have to ask; why compete?

Modern material extraction, processing and production of consumer goods have a commercial expense but add to that the rehabilitation of habitat from terra-forming and the toxicity of their waste accumulate an immense cost.

Ordered hierarchical structure

Biomimetics is either emulating or duplicating biosystems using mostly synthetic compounds and following traditional molecular chemical procedures2-4. With development in molecular5,8 and nanoscale6  engineering biomimetics has entered the molecular realm. Using natural molecular processes with nanoscale constructs molecular biomimetics is using hybrid methodology.7

Characteristic properties to be considered are; mechanical in nano-structured composites, magnetic properties of single domained particles, electro-conductivity of low dimensional semi-conductors, and properties in solution of colloidal suspensions10,11.

The control of nanostructures and ordered assemblies of materials in two and three dimensions still remains elusive 8 -11. Natural biomaterials are highly organized and often hierarchical in structure, with intricate nano-architecture that make a variety of functional soft and hard tissues. Rich Humbert and Mehmet Sarikaya of Uni. Of Washington have studied abalone nacre as a structural crystalline material.

Illustrations follow of biologically synthesized complex materials with details as you would see with a scanning electron microscope.

Humbert and Sarikaya also compared tendons for their elasticity and rat’s tooth for toughness.

Mouse enamel is hard, wear-resistant material with highly ordered micro/nano architecture consisting of hydroxyapatite crystallites that assemble into woven rod structure (inset: schematic cross-section of a human tooth)

In aquatic environments tissues are synthesized where physical conditions are moderate. The animal producing the tissue provides genetic input through its DNA and more likely physiological direction. The natural choice of molecule evolved by selection as a protein. Their molecules have a large carbon based chain where other molecular groups attach in various arrangements to the chain. Other carbohydrates and lipids can do the structural building. Proteins are versatile they collect and transport raw materials and they assemble molecular units, for example amino acid groups. Into ordered nuclei and substrates3,4,12. This is probably achieved through the excitation of electron revolving around nuclei attaining higher energy state and changing position to align with other compatible nuclei.

Engineered materials are made using a combination of processes like melting, solidification, thermo-mechanical working. Fire and temperature treatments are both energy demanding procedures. Or place materials in solution and apply vacuum deposition and growth processes16,17.

In total contrast biological systems have lengthy evolutionary selection processes which has given appropriate molecular recognition to an ordered process to build as required by the organism18,19.

Using biomimetic processes, hybrid materials could potentially be assembled from molecules using recognition abilities of proteins. As it is we know proteins assemble molecular units that fit by way of attraction of opposite charged sites and repulsion of like charged sites along the protein chain. An inorganic surface-specific polypeptide could serve as a binding agent to control the organization and acquire the desired functions of material parts.

The building of combined functional structures is possible with biomimetics. Genetic DNA coding dictates the molecular pattern in the protein that then becomes the template for building. Proteins can be used as adhesives to link synthetic units like nano-particles, polymer or other molecular structures into molecular templates. Given suitable physical and chemical opportunity biological molecules assemble themselves into an ordered structure as seen in natural structures, then possibly a hierarchical structure as seen in the shells of mollusks.

Rich Humbert and Mehmet Sarikaya of Washington University have studied the nacre(mother –of-pearl) of the abalone shell an incredibly tough structure, tendons are extremely pliable and strong and the impact resilient rat’s tooth as examples of high caliber protein based materials.

Present understanding of repetitious folding of protein molecules and surface adhesion chemistry is sufficient to deliver design of proteins20. To work around the choice of complex proteins data bases of generated peptides can be perused for binding properties to inorganic surfaces by using phage (eating and combining) and cell-surface display techniques21. ( see Further Reading below ) In the future it is plausible to facilitate a molecular erector manufacturing kit to make proteins designed to link to a specified inorganic surface that could self assemble into intricate structures composed of inorganics and proteins22.

Scientist like Paul Calvert of Arivona University, Materials laboratory in Tuscan “ … want to grow lattices with perfection in crystal size, shape, orientation and location especially in the ceramic world of insulation, bearings, wear and temperature resistant coatings and where specific optical, electrical and chemical requirements are needed. In the nano-world brittleness is the main issue.”23

Bones are crystals of calcium phosphate deposited in a polymer matrix. Diatoms – micro sea creatures – look like snowflakes, have skeletons made of silica glass shaped by the organic membrane of their bodies. Teeth in general, the spines of sea urchins, the shells of sea snails are very hard24, and are all formed of inorganic crystalline structures. The lamprey’s teeth are extra hard crystals to gnaw through rock. A bacterium Magnetotactic has managed to grow crystals of iron-oxide – magnetite in micro vesicles(balloons) inside its body.25 The magnetite vesicles line up in a chain assisting the bacteria to orientate itself toward the magnetic center of the planet, the anaerobic zone where they find their food source in bottom sediment26.

Magnetite nanoparticles (20 nanometers across) formed by magnetotactic bacterium (Aquaspirillum magnetotacticum) are single-crystalline, single-domained and crystallographically aligned.

The abalone emits a thin smear of polymer in its shell this matrix mortar is made of polysaccharides(sugars). Then the outer layer cells of the mollusk secret an organic mix in which the shell matrix proteins determine the mineralogical and crystallographic make up of the shell. This enables the formation of the hexagonal units within the shell structure27.

Growth edge of abalone (Haliotis rufescens) displaying aragonite platelets (blue, under a nanometer diam.) separated by organic film (orange) that eventually becomes nacre (mother-of-pearl). This is a layered, tough, and high-strength biocomposite .

Counter intuitive ordering of Structure

The Haliotidae family abalone’s cells secrete proteins and polysaccharides (other species may use lipids) into the fluid medium surrounding them. These polymers self assemble into three dimensional compartments that define the space to be mineralized. In the abalone’s case compartment after compartment is formed, layer upon layer is applied each off-set from the lower to achieve overlapping and interlocking structure.

Inside each compartment seawater – saturated with calcium ions and carbonate ions – eventually making a calcium carbonate crystal. The ions being charged are attracted to oppositely charged chemical groups protruding from the walls of the compartments. When the first layer of ions settle the pattern is established for the whole crystal.

The mollusk releases template proteins into the compartments. The protein polymers self assembly to line the walls in an array of negatively charged landing sites awaiting the positively charged ions in the sea water.

Protein molecules are very long chains with hundreds of amino groups. Each amino acid has a differing charge arrangement and those various charge arrangements pull the prtein to fold in a preferred shape when floating in the cell’s fluid.

The folded arrangement of the protein influences the amino acid behavior in water. Neutral, water repelling amino acids burrow into the center of a protein complex. Charged, water attracting amino acids go to the periphery. The amino acid groups interact similarly with one another, some repelling, some attracting to bond, What eventually develops is a form uniquely suited to its function.

A protein may have a structural role like assembling tissue or bone others may have a function like hemoglobin, insulin, neuron receptors, antibodies, enzymes(orchestrate and speed up chemical reactions), having shapes ideally suited to their task.

For the abalone’s shell the protein chain folds into regular zigzag shape which bonds with another ‘saw-tooth’ protein to form a piano accordion like pleated sheet. One face of the sheet sticks out into the room, the other bonds with the floors, walls and ceiling surfaces of the compartments. Daniel Morse, director of Marine Biology Center at the University of California, Santa Barbara has determined that the groups that bond to the walls are neutral (glycine and alanine) and those projected into the space are negatively charged (aspartate). The bond points (landing sites) on the pleats are defined by the folded points of the protein molecules which is regulated by the position of the amino acids every few nanometers. The Sea solution makes the charged ions float onto the oppositely charged bonding points of the pleats.

The arrangement of the first layer of ions determines the pattern of the crystal growth – rhomohedral in the case of the nacre(inner shell surface) – prismatic crystals form the outer shell. The crystal shape and its orientation gives the material qualities of light reflection and absorption or conductivity or hardness. Fourteen different crystal shapes have been found in natural materials.

Self Assembly

If you could apply a selection of protein into a cavity, allow the protein molecules to fold and layer the walls of the space. You could pump a solution of the desired ions into the cavity and the crystals would self-assemble to form the desired coating of the fourteen known kinds. This assembly is enabled by like charges repelling and opposite charges attracting. The electrostatic attraction holds the molecules together until more permanent bonds are locked into the key arrangements by catalysts like enzymes. All this assembly can only take place if molecules are available usually in a free moving fluid like air or water.


Template is a term for the appropriate sequenced protein that will orchestrate positioning and alignment of constituent molecular parts. The prime candidate for making them is E. coli bacteria. Humans have used bacteria, yeast, moulds for making beer, wine, bread, and matured cheese. Today it is used industrially  for food additives, antibiotics, chemicals and vitamins.

This topic continues in Designing from Nature’s Template {hyperlink here} the next Living Design Article.

Further Reading

Phage display is a laboratory technique for the study of protein–protein, protein–peptide, and protein–DNA interactions that uses bacteriophages (viruses that infect bacteria) to connect proteins with the genetic information that encodes them. In order to determine a peptide with affinity to a molecule of interest an iterative process of affinity binding and washing, called panning, is needed to yield an end result with a high concentration of high affinity peptides28.

Why design from nature? Part 3: ENERGY

Sturt’s Desert Pea

Our Sun Radiates Energy

The algae we see as green pond scum converts sunlight energy for its entire requirements at up to 95 percent efficiency, which is four times greater than solar photo-voltaic panels can manage.

Weed covered Melaleuca swamp

Duckweed also known as water lentils or water lenses come from four species (Spirodela, Landoltia, Lemna, Wolffiella and Wolffia) are small floating aquatic plants. They are monocotyledons meaning a flowering plant that bears a single cotyledon (embryo seed leaf)1. The small round thin leafed plants seen on slow moving waters is very fast growing which tends to obscure its microbial and phytoplankton reduction, and high nutrient and metal accumulation characteristics.

When the water is frozen it lies on the bottom consuming its own starch. In mid spring it surfaces and there reproduces copies of itself. It can cover acres of water in a few months all powered by sunlight.

Joseph Priestly is known for his descriptions of the isolation and identification of oxygen and other gases such as ammonia, sulphur dioxide, nitrous oxide and nitrogen dioxide2. But in 1771 he performed a demonstration in a jar bell, placing in it a mint plant with a burning candle. The candle flame used up the oxygen and went out. After 27 days, Priestley was able to re-light the candle. He was not aware that sun light was the unknown ingredient. It was later that In 1779 Jan Ingenhousz found out that in the presence of light, plants give off bubbles from their green areas, while in the shade these bubbles stop. He determined this gas to be oxygen.

Our sun broadcasts vast amounts of energy in an array of wavelengths. Green plants, some algae and bacteria can use a small portion of that light to energize the process of separating the hydrogen from water (thus releasing oxygen). The hydrogen is then in a form to combine with carbon dioxide to produce a simple energy rich sugar.  Animals (including us) use oxygen and the sugars to utilize the energy and emit carbon dioxide and water. These two processes occur every day, all day.

Leaf Structure. – Chloroplasts are distributed around the walls of all mesophyll cells of photosynthetic tissue.
Chloroplasts house thylakoids that absorb energy, releasing oxygen from water and transferring energy to a chemical system that uses carbon dioxide to form sugars

Our sun’s fusion of hydrogen delivers enough light energy to power all our needs without burning any fuel. Coal, petroleum oil, and natural gas are all created by compressing the remains of 600 million years of growth of plants and animals. The plants do the real work of converting solar radiation and storing it in greenery, grass, foliage and timber. To access that energy we burn the plant products; internally inside our cells or externally in fire. By burning the fossilized carbon fuels we release in one day what took one hundred thousand (100,000) years to form3.

The Mystery of Photosynthesis

IN 1912 Italian chemistry professor Giacomo Ciamican wrote in Science Magazine, he wrote of smoke stacks making way for ‘forests of clean glass tubes’ which would copy the ‘guarded secrets of plants’ using their natural processes to fuel our world.

Man has not fully understood the process known as photo synthesis it remains tucked away in the molecular arrangement of atoms in cells referred to as chloroplasts It is all to do with being green. Pigments in chlorophylls and carotenoids are light sensitive. Molecules in the structure of the membrane of chloroplasts act like antennae and collect photons of energy.

Light to energy > How nature does it

Chloroplast membranes envelop photosynthesis organs in an aqueous liquid that hosts other organs for sustenance and self-replication.

Inside a plant’s chloroplast inside its skin refered to as membrane are organs called a thylakoid. These thylakoids line up in a stack called a granum. Inside a thylakoid are thousands of chlorophyll molecules standing like a forest of tennis rackets awaiting a serve of photons. The various types of chlorophyll (a,b,c,d,e) absorb different wavelengths of light energy.

The broad end of the chlorophyll molecule is exposed to the photons and gets its electrons energized. This occurs in two photosynthesis systems simultaneously, we start with photosynthesis 2 (PS II).

PS II. A photon  with the 680 nanometer wavelength (nm.λ ) contacts the chlorophyll antenna, an electron orbiting the chlorophyll molecule is energized into a higher orbit. When the electron is whisked away it is replaced by an electron from a ‘Z’ donator molecule. The energized electron jumps from acceptor molecule to acceptor molecule. Then it is promoted to the PS I where it meets at central chlorophyll.

PS I. The charged electron goes to a chlorophyll that has received a photon with the 700 nm.λ. The electron transfer keeps hopping to acceptor molecule to acceptor molecule eventually a charged electron is found outside the thylakoid membrane.

Electrons excited by photon energy are powering enzymes to function through cycles.

This is the difference between a sack of chemicals and a living leaf. The concentration of molecules and charge is different to the concentration and charge outside the membrane and can be referred to as a potential difference. The membrane provides the tension between unequal concentrations and charge.

The membrane potential accomplishes a lot in plants feeding and refueling the entire plant. Splitting water, giving off O2+ and leaving H+ inside the membrane to form NADPH,

H+ + e + NADP+ –> NADPH   So then outside the membrane,

Electron after electron are passed onto nicotinamide adenine dinucleotide phosphate (NADP+) transforming it into NADPH which has the ability to donate electrons to other molecular compounds.

So NADPH donates an electron to carbon dioxide (CO2). However it needs energy to entice the H+ ions to form CH2O, sugar. [Now the potential difference either side of the membrane goes to work.]

Molecular interchange of ATP and ADP

2NADPH + CO2 –> CH2O (sugar) + 2NADH with the enzyme channeling the coupling factor

The hydrogen ion H+ gets through the thylakoid skin with an enzyme ‘channel’ referred to at a coupling factor. The positive charges escape through this coupling by turning Adenosine diphosphate, (ADP) to adenosine triphosphate (ATP) by adding the third phosphate to the other two with a high energy bond, which is the storage site of the energy gained from the sun’s photons.

Biochemist Thomas A. Moore has suggested applications of such an organic battery.

  • Hooking a chain of dipolar molecules to create a current.
  • Splitting water into hydrogen [a clean fuel] and oxygen.
  • Use it as a power pack to power solar based manufacturing.
  • Use it as a near light speed switch for computing.

Sustaining us today

Both animals and plants respire 4, I point this out to emphasis the cyclic nature of the whole ecological system.5 This diagram simplifies the process of cellular respiration.

Photosynthesis produces 300 billion tonnes of sugar a year6,7. Within the thylakoid stacks called a granum is the reaction center which is composed of a number of molecular groups called ‘cofactors’ within a tangle of protein referred to as the ‘protein pocket’. The cofactor localities outline a wishbone shape with a chlorophyll pair at the center with cofactor limbs facing each other symmetrically. An electron uses the cofactor limbs to transfer through the membrane incredibly fast.

Purple bacterium Rhodopseudomonas viridis a sun harvesting microbe is structurally far simpler than green plants believed to be kin to the first photo synthesizers 3 billion years ago. It has fewer unknown black boxes in its photo synthesis system.8 The purple bacterium can switch its reaction center from photo synthesis to respiration, oxidizing its food as animals do.

Converting the sun’s energy is all about storing the energy like we do charging a battery [NiCd, lead-acid] with an electric current. The battery’s potential difference, its charge needs to be stable if it is to be able to do work for us like making a light glow or running a drill. The same applies to photosynthesis, that potential difference either side of the membrane needs to be stable long enough to do chemical work in forming sugar and starch which are chemical energy store houses.

Neal Woodbury a chemist works with x-ray crystallography studies the light reaction center of R. viridis. He works on modeling the reaction mechanism in the photo synthesis of light photons energizing the relocation of electrons.  If you are not going to replicate the energy reaction center in thylakoids what molecules are you to use. Carotenoids are the pigment in the thylakoid’s antennae; porphyrins are similar to chlorophyll and also found in antennae. Some success was recorded when porphyrin was paired with an acceptor molecule quinone. The excited electron from porphyrin did move to orbit the quinine, but it extremely quickly returned to the porphyrin. Putting some distance between the charge differences seemed a strategy to employ.

So a third molecule, a catalyst was added to the donor and acceptor molecules to have a triad like shown below. The photosensitizer-(P) accepts a photon charge to energize an electron which transfers to the acceptor a proton reducing catalyst-(A), and an electron is taken from the donor-(D) which gets it by splitting water into oxygen molecule and hydrogen ions. 

The state of the triad with one catalyst oxidized on one end and the second one reduced on the other end of the triad is referred to as a charge separation, and is a driving force for further electron transfer, and consequently catalysis, to occur. The different components may be assembled in diverse ways, such as complexes with weak inter-molecular forces, compartmentalized cells, or linearly, covenant bonded molecules.9

general Triad scheme by PatriciaR

The pental is a five part donor – donor – donor – acceptor – acceptor molecular line up. The chemical signature is C – PZn – P – Q – Q  where C = carotene, PZn = Porphyrin with zinc, P = porphyrin, Q = naphthoquinone, Q= benzoquinone. It works when

  1. PZn receives photon energy.
  2. PZn loses its excitation to P.
  3. P transfers an electron to Q.
  4. PZn transfers an electron to P
  5. C transfers an electron to PZn , at the same time, Q transfers an electron to Q.

If the charge separation is spaced far enough, the natural tendency to return to its original location will be overcome.

For energy to be gained from the sun we need excitation to power electron transfer and hold the positive – negative charge (potential difference) in a stable location. The human species needs a means of storing high energy potential. Hydrogen is the choice in portable fuel cell development.

Getting hydrogen from water does not look difficult. Nature does it by photon excitation of electrons passed off to NADP+ then transforming into the electron donor NADPH. Provided we have H+ ions and a constant supply of electrons we have a clean fuel to collect.

 Water does offer up its hydrogen in the presence of a hydrogenase (biocatalyst). However after a few hours the hydrogenase is exhausted by the availability of oxygen and the reaction ceases.

Computers store and transmit electronic bits (I or O) one signal at a time. In the generations to come there will be 3D networks of switches, the signal will be encoded in light wave lengths. They will need light sensitive switched, perhaps a devise like a pentad which changes its charge distribution (the electron – vacancy positions) in response to light frequency.

Membrane polarization – is common in all biological functions. Photozymes – James Guillet of the University of Toronto works on ways to get light to the reaction center. In plants it is done with pigment antennae. Sunlight is diffuse – like drizzle instead of hard rain. The energy units – photons are hard to collect. Plant leaves, algae, photosynthesizing bacteria all use antennae to attract photons to their reaction center. About 200 pigment ‘tennis racket’  shaped molecules turn their porphyrin ring to face the light rays.

When a photon hits anywhere in the array, it excites an electron in porphyrin to a higher orbit, the energy (not the electron) moves to an adjacent porphyrin ring poised to receive the energy. Like energy from sound waves vibrating nearby materials.

The second photon infusion – having so many antennae there is more chance of receiving that second energy hit in close succession, so that will power a change. A good reaction center is powerless without the photons arriving as needed, i.e. almost simultaneously.

Guillet has managed to get naphthalene chains to conduct photon energy with the aim of using the chains as energy conduits to a reservoir to hold enough energy to split molecules like breaking the bonds in H2O –> 2H + O2-. Guillet found anthracene to be an effective receptacle to put at the end of a naphthalene chain. It proved to be as good at converting photons to potential energy as natural photosynthesis antennae.

Natural life systems have some common tactics whether it exists in plants absorbing nutrients, flowers growing into fruit, or the working of a brain. They use chemicals in an aquatic solution acting as the best solvent. Industrialized man uses solvents although called organic only because they contain carbon, have proved hazardously toxic.

The problem with naphthalene molecules is they does not stay suspended in water very long. A solution is to attach some hydrophilic molecules to the chain of naphthalene forming a hydrophobic package. Soap exhibits contrary characteristics. Its molecule has one end that is attracted to water while the other end is not water accepting and groups with other water non-accepting ends of molecules forming a molecular spiky ball. These soap molecular spheres are called micelle. The water hating cores attract other water resistant molecules nearby like greasy stain molecules which gather with the water resistant centers of the micelles and are washed away from fabric fibers.

Guillets new polymers form pseudo-micelle with energy gathering at their core. These pseudo-micelle act like catalysts or enzymes – photozymes. PSSS-VN made of two Sodium styrenesulfonate and two vinylnaphthalene. Tested on pyrene and polychlorinated biphenyls (PCBs are resistant to breaking down in sunlight). The photozymes can attract the PCBs in low concentrations and break off the chlorine from the PCB rendering them a less toxic state for further biodegradation. Doing chemistry in water using sunlight is most effective at the upper layer and diminished with depth. Nature shows us a solution on most quiet waterways, the surface clouding algae. It was the infamous duckweed that inspired James Gillet to develop little dish shaped discs that float on water. The discs hold the biochemical ingredients to be excited by sunlight and react in water. The product is scooped up from the water when required.

Nature’s credibility for success –                           

Cooperation is sustainable

Whales were not saved by an understanding of population thresholds. Once their blubber was discovered to distill into an efficient fuel oil they were hunted to near extinction in a single generation. Whale blubber for oil was replaced by the petroleum industry and vegetable oil substitutes. Forests are not preserved for their diversity. They are saved when the cost of extraction outweighs the immediate financial gain. When the red cedar or the huon pines are gone from the forests, distance and remoteness are their best ally. Similarly fish stocks are not being managed for future availability; we are caging them in floating farms on the oceans or inland ponds.

Forest devastated, glade stumps remains.

The notion of limits is a dare to humans. It comes down to ideology. Is the earth our mine site? Or, is it our home? Will we discover nature’s secrets and exploit them at the expense of other species and their habitat? On seeing vultures gliding in flight, the Wright brothers were inspired to invent the mechanical wing. Flying machines were soon adapted to another devastating war machine. Will we see the natural environment as our mentor? A self sustaining system to be protected, to learn from and emulate.

Do we have the intelligence, humility and compassion to work with nature? A ten year old Swedish girl, Greta Thunberg has taken a leading stand to publicize the need for action to reduce climate change. A pity the repeal in October 2017 of the Clean Power Plan in the US, or in September 2018, the Climate Risk Disclosure Act, or in July 29, 2019, the introduction of the Climate Equity Act, a bill that proposed to protect the health and economic well-being of all Americans for generations to come, attracted so little publicity.

The Earth is its own food resource

Nature runs on sunlight and uses all its waste. So if we and this planet are to continue to flourish, questions arise.

  • How do we grow our food?
  • What do we grow?
  • How should we make our materials?
  • How should we power our lives?
  • How should we heal ourselves?
  • How should we conduct business?

The industrialization of agriculture has seen an end to diversity. Vast monocultures of sugarcane, rice, macadamias consume the landscape. Crop growers sow broad acreages with single variety species, all at the same stage of growth. When a crop fails the loses are disabling. The eternal optimists, farmers are at risk from pests, parasitic species and disease, winds, erosion, drought, fire, rain, hail and flood.

Farmer plows his tractor through a degraded pasture and Carcará hawks seek food in the rural lands of Arco-Iris, in Sao Paulo State.

A number of farmers in the prairie lands are maintaining the native vegetation. They are finding the native grasslands are resistant to erosion because the perennial grasses are deep rooted. Pest infestation damage is short lived because the numerous plant species are able to contend with the pests’ preferences. And the grasses do not require artificial chemicals for protection or nutrition; they do need sun and some rain. But they are less reliant than annual crops for water in their growth cycle.

No need for cultivation, seeding or fertilization on the prairies. In fact they mulch their own waste discarded dead fiber. The grasslands’ own genetic modification occurs on site from year to year. If agriculture co-existed with the native habitat then it would depend on where you are.

Here in north eastern New South Wales just nestled below the Border Ranges that sees the warm air of Queensland meet the cool wet south easterlies of coastal Australia an average rainfall of sixty inches a year, sub-tropical rain-forest would soon (in one generation) re-establish itself after the historic falling of the red cedar, followed by clearing for cattle. Now replaced by a mono-culture of macadamia plantations. Managers clear all vegetable matter from their manicured plantation rows to allow the nuts to be mechanically gathered from the ground. Considerable energy is then expended removing the dehiscent husk to reveal the nut shell, the hardest seed coating known to dietary science. This and a combination of processing drives to cost the consumer eight times that of its harvested value.

Others would consider grassed plains as their native habitat or dry woodland. Not to forget vast areas of shrub dotted desert.

Lazar leveled fields to assist the mechanical tilling, watering and harvesting by massive diesel powered vehicles may well see the ‘Dust Bowl’ of the Mid West of the 1930’s drought revisit. Then cows used the soil dunes to walk over fences. And what the wind took never came back like a tidal sand might deposit. In the Southern hemisphere New Zealand’s Alps sometimes wear a pink coating of Australian top soil blown across the Tasman Sea. It takes three hours to fly the colloquial ‘ditch’.

Sustaining us today

Planting crops commenced 10,000 years ago, break open the top soil, rake over the bed for seed, nurture to green shoots and think life is wonderful when you got the fruit. Some certainty developed in human life. Crops grew every year. Our children had a regular food supply and did not rely on the chance and gamble of the hunt and forage. Then we had more babies and we needed more grain. More of everything we came to expect, food variety, clothing, shelter, beasts to do our labor and transport. We needed surplus to sell and pay for imported luxuries.

Crops became vital, we gave them every advantage, removed competing plants, lavished fertilizers, killed any threatening pest, and selected the best producing crop variety. In doing so we removed their resilience and genetic diversity to enable the species to adapt to changes in their environment. Top soil is extremely difficult to replace once it is lost. I have heard it said that top one inch of your soil took one hundred years to establish in a forest. Tilling the top soil radically disturbs the soil structure inhabited by micro flora and micro fauna that glues it into colloidal communities. A structure that is the circulatory system for the earth, delivering nitrogen with rain. An arrangement of soil particles that clump and create passage for water and air to come and go. Providing spaces and passage ways for water, gases, nutrients, roots and the vast populations of organisms that convert matter into solution.

Soil cut-sandstone, stones, clay, sand structure and slice of sand with sedimentary layers.

Dry air blowing across the ground pulls moisture out of it. Powder dry soil becomes air borne dust, blown away. If rain does fall the drainage filigree is not there to direct the water to roots. It sheets and floats in rivulets carrying soil to the flood plains, rivers and the sea. The soil is neither moist nor capable of fertility. Fungi cannot assist roots, organisms cannot break down decayed material into nutrients, bacteria cannot deliver nitrogen to the roots of plants.

The ‘dust bowl’ of the Mid West plains of the 1930’s was a tradegy. Washington D.C. responded by setting up the Soil Conservation Service which oversaw the planting of perennial deep rooted grasses, but have we learned? Soil loss from industrialization of cropping is only one in a great list of faux pars committed on the colonial landscape by a European vision of what agriculture should be. The introduction of inappropriate seed crops; rice with its over reliance on water, and sugar cane heavily in need of artificial fertilizers. And into the second decade of the 21st century cane farmers still think it is acceptable to set light to the landscape to burn the trash, unwanted outer leaves because it interferes with production process to create refined sugar. No wonder at the high incidence of diabetes in Western society.

Introduced species, rats, rabbits, hoofed beasts including deer damage the soil surface and destroy ripperian zones on creek banks. One property owner wiped out a local platypus (Ornithorhynchus anatinus) population just in case one of his cows broke a leg in one of the semi-aquatic monotreme’s burrows on the creek banks in his property. Worthy of placing on our coinage but not in our back yard. The Sydney Museum has a full length fur coat made from the pelts of platypus to remind us. Discarded dogs and cats create havoc among native species endangering further their survival. Camels, the jury is still out conferring on their legacy. Central Australian entrepreneurs export them to Arabia.

We have had the industrial revolution, now we have what a clever marketing executive has named the ‘green revolution’, bringing hybrid strains of plants that will ‘dramatically improve yield’. Save a portion of last year’s seed for sowing? Why? The new highly productive seed is much better. Except it is infertile and you will need to buy it every season. Thousands of varieties that naturally adapt season by season to local climatic conditions were discarded for one ‘super yield’ hybrid.

Chemical protection

Pests and weeds in a field of a single variety will need pesticides and herbicides. Unfortunately they do not kill all pests nor all weeds. Some survive to infiltrate next year’s crop. Stronger doses of poison are applied on our crops and landscape. One supplier is offering pesticide pre-treated seed at a cost. Dozens of seed supply businesses have been bought out by petro-chemical companies.

Machines have replaced labor but farms have incurred considerable debt to fund them. The constant pressure of repayments on loans forced farmers into broad acre agri-business; lazar leveled fields for the super cultivators, one species for efficiency, and continuous cropping with high fertilizing additives adding more expenditure. No switching to replenish soils with legumes. Chemical fertilizer is the quick fix to treat the symptom, instead of treating the disease of soil degradation.

The petro-chemical companies provide a protective ring to ensure a high yield. The spraying of herbicide and pesticide escalates. Now glyphosate1 can be detected in every commercial food2. Farmers were lead to believe hybrid seeds immune to herbicide; no more concern over residual herbicide in the soil.  They can use as much as they want. Health implications arise, carcinogenic probably.

The net result of all this specialization is fewer and fewer people on the land; less vision, less observation, less intellect, less creativity directed at farming. As well as biological monoculture the rural landscape has little diversity in thought.

Wes Jackson director of the Land Institute works at ‘devising agriculture that is more resilient to human folly’. Modern agriculture is totally independent of the natural systems and habitat. The domesticated animals in feed lots were once wild. Their eco-systems were fuelled by sun light. They promoted their own fertility when seasonal conditions were favorable. Pests they learned to cope with strategic behavior or grew resilient.

Ben Smith geneticist at Nth. Carolina State voiced, ‘We need wilderness as a standard against which to judge our agricultural practices.’ A single native patch of Kansas prairie had 231 species4; grasses, sunflower, legumes, fern like forms, nitrogen fixers, deep rooted, shallow rooted, quick growers in spring, pest resistant, beneficial insect attractors, butterflies, and bees to pollinate. Below ground level thousands of species; ants, centipedes, soil bugs, worms, bacteria and molds burrowing, eating, excreting, depositing nutrients in the humus matrix available for root absorption. 

Below ground level is entwined with plants and above ground with animals. Plant a new species or introduce a new animal the earth community responds to that change. It will adapt, but catastrophic change, living systems will stop functioning.

When you plow, spray pesticides and harvest you change a great deal. Beneficial micro-organisms that help deter insects or assist in pollination or root development are all gone. ‘Our goal at the land Institute is to design a domestic plant community that behaves like a prairie, but that is predictable enough in terms of seed yield to be feasible for agriculture,’ says ecologist Jon Piper. Almost all plant species are perennial; their roots remain to hold the soil together in wind and rain. The diversity of natural pastures has many species, some as summer grasses, some as nitrogen fixing legumes. Different species flourish in differing conditions.

Yucca elephantides utilized as a hedge.

Yucca elephantipes closely related to Yucca aloifolia and gloriosa.6 Similar to the Joshua Tree (Yucca brevifolia) the largest of the species.

The Mid West prairie has yucca3 which does well in the dry and the big Bluestem goes skyward in the wet. Pests will target a preferred species, but when confronted with many species they will have more difficulty multiplying their populations. The prairie has four classic plant types; warm season grass, cool season grass, legumes and composites. Cool season is generally early spring flowering with seed setting and blowing off by spring’s end. The warm season grasses flourish through mid summer. The legumes like; oats, claw, sensitive brier and lead plant fix nitrogen which benefits all of the plants. Composites like golden rod, compass and asters can flower any time throughout the season.

Studies of assembled plant communities suggest that in order to sustain themselves persistently they need no fewer than eight species. Land Institute scientists under the direction of Wes Jackson are looking for perennials that may be encouraged to yield food crops.

Method one chooses a wild perennial and enhance its seed production. Method two, take a crop bearing annual and cross it with a perennial that copes with winter conditions in nature. Look for good rhizome development – the underground runner that allows plants to store starch for the dark season.

Likely candidates like

  •        Illinois bundleflower (Desmanthus illinoensis) a perennial that has produced seed consistently at 800lbs per acre, its tall seed pods are attractive to deer and quail.
  •        Eastern gamagrass (Tripsacum dactyloides) a warm season grass, related to corn.
  •        Mammoth wildrye (Leymus racemosus) a cool season relative of wheat.
  •        Maximilan sunflower (Helienthus maximilianii) a composite with oily seed.
  •        Johnsongrass (Sorghum halepense), is a perennial in the grass (Poaceae ) family, native to the Mediterranean region.
  •        Grain sorghum (Sorghum bicolor), also known as great millet, durrajowari, or milo, is a grass species cultivated for its grain, used human consumption, animal feed, and ethanol production. Sorghum originated in Africa, and is now cultivated widely. S. bicolor is typically an annual, but some cultivars are perennial. It grows in clumps that may reach over 4 m high. The grain is small, ranging from 2 to 4 mm in diameter. 
  •         Wild senna (Cassia hebecarpa) a lugume that forms seed pods which will attract turkeys.

Most cropping is conducted with exotic species or their hybrids from Europe or Mexico. American native species cultivated are sunflowers, cranberries, blueberries, pecans, concord grapes and Jerusalem artichokes.

James Drake and Stuart Pimm of the Uni. Of Tennessee have studied plant communities and analyze what is necessary for these assembled plants to live in equilibrium. They have come to a hypothesis that it is all about history. The community needs to have evolved, some arrivals grow, some die out. Animal involvement needs time to reach a state where change can be survived by some suffering but others flourishing.

Plants in these communities are not competing for the same things as an identical plant would have to. And they are better situated to resist insect and disease attack. Insects are presented with a diverse array of foliage and chemical strategies to fend them off in a poly-culture. Where as in a monoculture, once the insect discovers its attractive sweet parts it spends all its opportunities consuming. Diseases are more complex and finding a host is not as easy.5 Where legumes are present in the assembly the tiny nodes on the roots convert airborne nitrogen into plant food for themselves and others nearby.

Locations differ in their ecosystems so the natural native habitat will differ due to factors like; sunlight cycle, ground conditions, weather patterns, animals and bird life, plant diversity. Permaculture advocate Bill Mollison said, ‘ask not what you can wring from the land, but what the land has to offer.’ Bioneers John and Nancy Todd founded the Alchemy Institute in 1969 using ‘living spaces and food production systems using nature as a model. The forest-in-succession concept for a self sustaining farm.’ The succession in a forest optimizes the use of;

  •        space [pioneer plants take root in exposed places],
  • biotic elements [microbes, fungi, earth bound insects and worms breakdown humus, leaf litter, animal remains into compounds the plants consider nutritious.]
White thread like fungus generated from wet and humid soil.

The jungles of Cost Rica are a bountiful paradise of luxuriant vegetation and sun ripened edible foods. But colonialist cleared them to plant European crops. They did well at first but subsequent tropical deluges leached the nutrients from the soil. From then crops diminished in yield. Botany professor Jack Ewel of the Uni. Of Florida with a colleague Corey Berish cleared two plots in the tropical jungle then let then reseed and naturally regenerate to native jungle. One they left to nature the other they dug up the regrowth and replaced it with a human food variety that had the same physical characteristics as the native. Taking natures’ sprouting as their guide they replaced annual for annual, herbaceous perennial for perennial, tree for tree, vine for vine.  The domesticate jungle plot appeared and behaved like its native neighbor. They both displayed fine root systems and identical fertility measurements.  The natural habitat of Heliconia paradise plants, annual gourd vines, sweet potato and other Convolvulaceae family plants, legume vines, shrubs, grasses were replaced by plantain, squash varieties, and yams. Subsequent years fast growing fruit and nut trees like Brazil, peach and palms were planted. Two control plots both cleared one planted with rotating crops, both soon lost their fertility because the nutrients were not replaced by leaf and humus decay.

Robert Hart, permaculturalist published guidelines for harvesting systems that would mimic rainforest ecosystems. He included ‘cassava, banana, cacao, rubber, and timber trees like cordial and swietenia. Ultimately his system would have three tiers to function as a rainforest where plenty of leaves and roots shielded the soil from torrents, nutrients were stored in biomass, vegetable matter was recycled into the soil. Use plants that had symbiotic relationships with other inhabitants like fungi. Deep rooted plants used nutrients from different parts of the soil.

In his book Gary Nabhan looks to the Papago and Cocopa peoples of the American South West where rainfall is erratic and seasonal. The patchy vegetation congregates in fanning clusters. By planting in the flooding alluvial fans they avoided the need to irrigate. As well as annuals the Papego also planted succulents, grasses and woody plants for food and fiber. They also left mesquite trees about their sites for their leguminous properties.

Ecological accounting

By isolating the agricultural system and counting all the inputs and outputs you can determine if they will sustain themselves. Firstly the must be able to support farmers and their communities. Secondly you need to measure more than financial units, someone has suggested using kilocalories; you need to tally energy and land resource consumption, and their sustainable replacement. That should account for issues involved with fertilizers, fuel, transportation, health, as well as the obvious chemical contamination, atmospheric contamination and their costs to the wider community.

Nature’s credibility for success –                           

The Earth is its own resource

Stromatolites, tidal coast Western Australia

Stromatolites – Greek for ‘layered rock’ – are microbial reefs created by cyanobacteria (formerly known as blue-green algae are a division of microorganisms that are related to the bacteria but are capable of photosynthesis. They are prokaryotic and represent the earliest known form of life on the earth. From Oxford). 

Oxygenic photosynthetic bacteria perform photosynthesis in a similar manner to plants. They contain light-harvesting pigments (as chlorophyll does for plants), absorb carbon dioxide, and release oxygen.1  Stromatolite deposits are formed by sediment trapping and binding, and/or by precipitation activities of the microbial communities (Awramik 1976). The microbes are active on the surface layer of the Stromatolites, while the underlying build-up is a lithified [hardened into stone] remnant of former microbial surface communities, that could be interpreted as a trace-fossil.

These deposits built up very slowly: a single one metre structure may be 2,000 to 3,000 years old. But the tiny microbes that make up modern Stromatolites are similar to organism that existed 3.5 billion years ago. Stromatolites have thrived for almost 85% of the earths history, they play a crucial role in regulating sedimentation and global biogeochemical cycles.

Proterozoic Stromatolite

Microbial lithfication represents the major evolutionary advance that enabled stromatolites to thrive for so long. Stromatolites are essentially a buildup of microbial mats that grew on top of each other with the upper most layer being occupied by bacterial colonies however not all lithifying mats form stromatolites, just those that form layer upon layer. Microbial mats form extensive platforms for trapping and cementing sediment. They are vertically laminated, sedimentary biofilms. Found in ares such as lagoons, marine subtidal zones, lakes, fresh water rivers and hypersaline ponds

Sustaining us today

Agricultural practices evolved gradually to replace hunting and gathering cultures with a few remote exceptions like the San and the Inuit whose habitat provides all the need to sustain them.  

World over indigenous peoples and their native habitat is being displaced by super sized technologically advanced machines to rip out what ever efficiently fashionable resource they crave; gold, silver, metallic ores, oil and coal. One million years after the first humans formed tribal culture we are still scrapping away vegetation, humus and nutrient rich top soils to mine coal.             That soil from its first terrestrial inputs has taken 4 billion years to evolve. Life in all its wondrous forms has spread to cover the planet. Plants converted sun’s energy to simple sugars providing nutrients for insects that flew to cross pollinate. Fish thrived on animals that eat the tidal sediment, and birds navigated over the waters and caught the fish. Their waste was all recycled as nutrients for plant life.

The failures fossilized, survivors are the winners that live with what nature provides without burning the fuel that was fossilized millions of years ago.

Scientific revolution

Global expedition for trade sustained an interest in natural science. Botanist Joseph Banks2 brought extensive collections of rock samples and wildlife back from eastern North America. He also returned to England with experience of transport across oceans. The British benefitted from James Cook’s pacific surveys, substantially funded by Banks the philanthropist who took a staff of eight; naturalists, artists, tenant servants, and his own library of natural history. They gathered large collections of specimens recorded detailed observations at; Rio de Janeiro, Tierra del Fuego, Tahiti, New Zealand and the eastern coast of Australia, New Guinea coast, the island of Savu, Jakarta, the Cape of Good Hope and St Helena. The findings of his collections and journals eventually became available to; the Navy Board; the Royal Society, the Society of Arts, the Dilettante Society, the Society of Antiquaries, the Royal Institution, the Engineers’ Society, the Literary Club, the Horticultural Society, the Institut de France, the Linnean Society, the British Museum, the Board of Longitude, the Coin Committee and Committee of Trade of the Privy Council.

Banksias thrive in this parched land

He paid collectors to acquire specimens from the Cape, West Africa, the East Indies, South America, India, Australia. Further from the voyages of Cook’s , Bligh’s voyage to the South Seas, and George Vancouver’s voyage more collections were gathered included in the 7000 new exotic plants for collections of King George III now exhibited at Kew Gardens. I applaud the extent of his collections of drawings, seeds, live plants as a genetic resource for the enrichment of botanical knowledge.

Industrial revolution

Smoke belching chimneys over factories black from soot was the sight of the workplace for most city workers of the late 18th century. Machines we know from their iconic names;

  • Spinning Jenny wound thread on multiple spindles,
  • Water Frame powered spinning machines,
  • Industrial Power Loom displaced the flying shuttle and mechanized fabric weaving,
  • Bessemer process for smelting manganese steel. The converter blasted the charge of pig iron with heated air liquefying the steel to pour it off separate from the residue.
Bessemer smelter and process
  • Newcomen’s atmospheric engine converted steam to pumping action, modified by,
  • James Watt’s Steam Engine employed to pump water out of mines.
  • Dynamite made of nitroglycerin, sorbents and stabilizers one of which was “diatomaceous earth”, which is a soft rock mostly made of fossilized algae.. Invented by chemist and engineer Alfred Nobel 1860’s it rapidly gained wide-scale use as a more powerful alternative to black powder. 
  • Seed drill is a horse drawn devise that sows the seeds for crops by delivering them into the soil at the proper seeding rate and burying them to a specific depth. This ensures that seeds will be distributed evenly to maximize crop growth.
  • Puddling was an important step in processes of making appreciable volumes of high-grade bar iron during the Industrial Revolution. In the early puddling method, molten iron in a reverberatory furnace was stirred with rods, which were consumed in the process.
Stephenson’s Rocket locomotive fueled by coke

Mechanisation to increase productivity was in full swing making more quickly drove industry to new highs. Flour milling had used the water wheel for centuries, but then the steam engine arrived then materials and products could be transported in bulk.

            Now we have the petro-chemical and genetic engineering revolutions. ‘Predetermine DNA to do our bidding, then we feed it into the juggernaut of technology’ monopolizing vast areas to produce crops where nothing is allowed to compete for resources

            An ecological tenant that even humans must abide; ‘a species cannot occupy a niche that appropriates all resources.’3 Our habitats the cities and their surrounding agricultural plains are not self sustaining, they require great volumes of inputs from other zones, hence they are unstable. And chaos theory tells us a system which is unstable is likely to change.

            Natural evolution leapt in breakouts of climatic crisis after long plateaus of constancy. Particulate clouds in a sunless winter after an asteroid exploded in the Mexican Gulf off the Yucatán Peninsular ended a 100 million year reign of the mega fauna. The understanding of natural science is doubling every 5 years, the impetus is coming from technology like satellite sensing, drone photography, neutron microscopic vision and we see more clearly the patterns of systems. Innovations have already been achieved in some form from observation of nature.
