It's not electric, but this micro-turbine powered truck is VERY efficient and it uses ZERO oil for lubrication! Methane harvested natural gas from animal poop or soil decomposition could power it Renewably!   ;D

Colorado town is first in the US to switch to renewable   natural gas

By Ethan Weston

transcript provided by Newsy.com

The city of Grand Junction, Colorado, is turning its raw human waste into a type of renewable natural gas called biomethane,  according to The Guardian.

It's the first city in the United States to do this, according to NPR.


The gas is produced as organic matter and breaks down into raw biogas. It's then refined and can be used in any system compatible with natural gas.

The city plans to use the gas to run about 40 vehicles in its fleet.

The thing about human waste is it's always going to be available, which makes converting it into a usable form a pretty smart move. And the gas produced is better for the environment.

Renewable natural gas that's burned as fuel becomes 21 times less potent than if the methane had been released directly into the air    , according to the American Gas Association, a consortium of 200 energy companies.

A utility engineer for Grand Junction told The Guardian that the city
Quote
"may be reducing greenhouse gases by as much as 60 to 80 percent."

And biomethane doesn't just come from human waste, according to the Department of Energy. It can be captured from landfills, according to the Environmental and Energy Study Institute.  Also, livestock waste, according to The Wall Street Journal. These are two of the top producers of methane in the United States.

As for the cost, a manager at the treatment plant told NPR the savings could be in the "hundreds of thousands of dollars."   And the city expects the project to pay for itself in about seven to nine years.

The National Association of Clean Water Agencies found that energy produced by wastewater treatment plants could meet up to 12 percent of the national electricity needs alone:o  ;D  So maybe Grand Junction is just ahead of the curve. (Video via Doug Von Gausig)

I do think biomass will be a big part of our energy future, if there is an energy future.

CH4, otherwise known as methane, can be obtained from animal feces Methane Harvesters without ANY flaring or ANY aquifer polluting side effects that are sine qua non to Fracking. Fracked CH4 gas is NOT "natural" gas. Methane harvester CH4 IS RENEWABLE ENERGY, POLLUTION FREE, NATURAL GAS. The ERoEI (Energy Return on Energy Invested) of CH4 from Methane Harvesters is FAR MORE than that of CH4 from Fracking.

Agelbert NOTE: Nature provides an economic Blessing. Homo saps think its a curse.   

Holy Bats, Batman!

Batsh*t crazy! Swarm of 100,000 bats invades Australian town (VIDEO)
Published time: 25 May, 2016 18:00


© Tim Wimborne / Reuters

An Australian coastal town is nearing a state of emergency, but the cause isn't an earthquake or flooding. Instead, it's a natural disaster of another kind – 100,000 bats have embarked on the community, drastically outnumbering its human residents.

The bats arrived in Batemans Bay, located to the south of Sydney, with a bang – or, rather, with an odor and a terrible screeching noise that's driving the town's 11,000 residents insane.
 

"I can't open the windows, I can't use the clotheslines… I can't study because the noise just goes constantly. I can't concentrate. It's not fun. The bats came and they are just out of control. We just can't do anything because of them," local resident Danielle Smith told Sky News Australia.

But it's not just ordinary locals expressing concern about the town's most unwanted inhabitants. New South Wales Environment Minister Mark Speakman said the circumstances “really almost amount to a state of emergency,” the Australian Broadcasting Corporation (ABC) reported.

"We've had many residents complain, they feel they're prisoners in their own homes, they can't go out, they have to have air conditioning on the whole time, windows closed,” he added.

Speakman went on to note that the government believes the number of bats from this particular species – known as grey-headed flying foxes – represents about one-quarter to one-fifth of the entire national population.

But despite being a huge nuisance, local authorities are completely banned from using lethal methods on the bat species because they have been declared vulnerable. Animal rights activists are also keeping a close eye on the situation, calling for patience among locals.

In an effort to deal with the problem morally and ethically, the New South Wales government has now committed AUS$2.5 million (US$1.8 million) towards a remedy.

"The current method that seems to be the one that's working the most...is extremely loud industrial noise combined with smoke and combined with bright lights in an effort to make the area where the flying foxes roost to be as uncomfortable as possible," said Lindsay Brown, the mayor of Eurobodalla Shire Council, which administers Batemans Bay.

For now, residents of the tiny Australian town hope Brown's optimism isn't misplaced, and await their fate in a community where flying foes seem undeterred by any efforts to rid them of their adopted home.

This reflects the typical Homo sap WRONG reaction to a potential guano goldmine.

Since the 19th century guano has been the gold standard of fertilizers.

You can make a LOT of money from gathering and selling a ready source of Guano.

I took a tour of one of our three poo-poo treatment plants a couple of years ago.  Settled out product was conveyed to one of five methane digesters which are huge concrete tanks several stories tall.  Methane is produced for a few weeks and then the residue is trucked to eastern Washington for use as fertilizer.  It makes wheat grow very well.

On any given day the methane is sold to the gas company or it is burned to generate electricity and sold to the electric company to offset the plant electric bill.  The methane extracted is only enough to provide one fifth of the power the plant actually uses.

This plant receives its raw material from a mixed flow of storm drain and sewage waters.  The area served does not have a separate storm drain system though there are some street drains with fish painted next to them that claim to drain directly into Lake Washington.  The relevant fact is that product to produce methane arrives quite dilute.  This may explain some of the poor efficiency.

I am going to look into how much methane is produced by a single pig's poop on an annual basis but don't let that stop anyone from posting what they know about the process first.

I do know an elephant produces enough methane to keep a range burner on because they process their fodder very inefficiently.  They are not ruminants.  Elephant poop is apparently important to distribute nutrients in their local environment and because they don't get all the energy they could from their feed elephants are consequently always full of ****.  The Republican mascot is well chosen.

My point is that, like the blood of patriots, the waste product of methane digestion is useful as fertilizer.

But how many therms can a pig toot?

The problem here is the generally accepted notion of "carrying capacity" that is riddled with false assumptions on the nature of energy transfer mechanisms in autotrophs (photosynthetic sunlight eaters).

From the simplistic application of Hess's Law to the cherry picking of the fossil fuel funded Charles Halls of this world, we get an amazing array of studious peer reviewed bullshit about "carrying capacity", caloric intake requirements and required nutrients.

The fact is, K-Dog, that nitrogen fixation and other plant health and growth (NOT the same thing!) processes are complex. The thermodynamics of soil microbes is not well understood because off their enzyme mediated energy transfer systems.

The reductionist and moronic 20th century Big Ag assumptions that all you needed to grow a healthy crop are phosphates, potassium and nitrogen are based on FALSE assumptions about autotroph energy (AND HEALTH) requirements.

NOBODY has quantified ERoEI in soil microbes, of which there are several MILLION per cubic INCH (including thousands of DIFFERENT SPECIES). When they do, we can begin to understand carrying capacity. Until then, assumptions about energy from fertilizer are not based on the important, and sine qua non, thermodynamic mechanisms of the soil microbes.

A Methane Harvester  in Germany

150 new biogas plants with a joint capacity of 23 megawatt were installed in 2015, the
German Biogas Association (Fachverband Biogas) reports.

Some 130 of them were small facilities running on liquid manure, others included biomethan and waste fermentation installations. 2015 marked the least addition to the German biomass-power capacity since 2000  :(, the association said.

Twenty plants were retired in 2015, leaving a total installed capacity of 4,018 megawatt that can supply eight million households. With the 2016/2017 reform of the Renewable Energy Act, the sector was regarding the future more promising , a press release said.

The German Biogas Association represents primarily operators and manufacturers of biogas plants in Germany. It has 4700 members. It lobbies for the increased use of biogas technologies as the only renewable energy that can be switched on and off when needed and thus provides system stability

More to biofuels than CO2 reduction   

 Thursday, May 4, 2017

Failure to account for non-fuel related benefits from biofuel production leads to an underestimation of the greenhouse gas (GHG) emission reduction potential for biofuels when replacing fossil fuels due to the many valuable by-products and/or co-produced utilities with high fossil replacement potential. With the current Swedish biofuel production portfolio, consideration of non-fuel related benefits could lead to 50 percent greater GHG emission savings, a recently concluded project finds.

In 2014, the Swedish Energy Agency reported a greenhouse gas (GHG) emissions reduction of 1.95 million tonnes of carbon dioxide equivalent (CO2-eq) due to the replacement of fossil fuels with biofuels. However, a narrow focus on CO2 fails to capture the additional benefits biofuel production may have according to a recently concluded Swedish research project.

Over 16 percent of all fuel used on Swedish roads during the first half of 2016 were renewable.  


GHG reduction benefits of biofuel production underestimated according to a new study.

Studies often indicate that agricultural and biomass production systems have the potential to provide considerable socio-economic benefits, but that the level of detail and clarity regarding benefits provided by expanded biomass production and biofuel process industries are insufficient.

Furthermore, the significant focus directed toward investigating the life cycle impacts and negative socio-economic effects of biofuel production tend to exclude, miss, or ignore additional benefits from the biofuel industry accrued in both environmental and socio-economic spheres.

This was the starting point for a recently completed project within the Swedish Knowledge Centre for Renewable Transportation Fuels (f3) and Swedish Energy Agency collaborative research programme Renewable transportation fuels and systems (Förnybara drivmedel och system).

Factoring non-fuel GHG emission benefits

Project leader Michael Martin from IVL Swedish Environmental Research Institute has worked together with participants from f3 partners Bio4Energy/Luleå University of Technology and Lund University to study the additional socio-economic benefits that also come from replacing fossil fuels with biofuels.

The project Environmental and socio-economic benefits from Swedish biofuel production, has quantified and analyzed environmental benefits, and reviewed and documented socio-economic benefits of biofuel production in Sweden.

The results from the environmental analysis provide evidence that failure to account for non-fuel related benefits from biofuel production leads to an underestimation of the potential for biofuels to contribute to GHG emission reductions when replacing fossil fuels due to the many valuable by-products and/or co-produced utilities with high fossil replacement potential.

Prime examples of such being by-products from grain-based ethanol production, digestate from biogas production, and utility integration of lignocellulosic fuel production such as fuels derived from biomass gasification.

Göteborg Energi’s Gothenburg Biomass Gasification Project (GoBiGas) is the world’s largest woody biomass gasification demonstration project.

With the current Swedish biofuel production portfolio, consideration of non-fuel related benefits could lead to 50 percent greater GHG emission savings, compared to when only considering the replaced fossil fuels. In the considered future fuel production mix scenarios the corresponding number could almost reach 90 percent, due to significantly increasing shares of biogas and lignocellulosic biofuels.

The results from the project have been submitted in two scientific articles that are to be published. An additional supporting report that elaborates on the socio-economic benefits through a screening and review of job creation and assessment methods for other benefits is also under way. In the meanwhile, an extended summary report is available.
