41Cleaner than cow farts, Elio 84-mpg trike hits 15,000 reservations

If you think the fact that Elio Motors has taken 15,000 reservations for its high-MPG three-wheeler is something to scoff at, well, consider the fact that Honda sold less than 21,000 of its hybrids, plug-in hybrids and electric vehicles combined last year. But, if you think that the company's claim that the trike is cleaner than a year's worth of farts from a cow? Well, go ahead and scoff.

2Toyota turning landfill gas into hybrid vehicles, indirectly

Chamillionaire certainly wasn't referring to the Toyota Avalon or Camry when he rapped about "ridin' dirty" but maybe he'll change his tune soon. That's because some of the future energy sources for the Kentucky factory that makes those two models will come from gas created from the breakdown of solid waste. So the power behind some of the production at Toyota's largest North American factory will indeed be funky.

AddHigher ethanol blends create health, safety risks, says Big Oil-funded study

In the simplest terms, when higher-ethanol blend fuels spill, they can make buildings go boom. And the study that says this was funded, in part, by Chevron and Shell as well as the American Petroleum Institute, while the report was generated by Rice University in Houston. All clear on the players? Good. Let's proceed.

43In producing natural gas, excessive methane leaks offset environmental benefits

Utah, we have a problem. That's the conclusion of a report from the publication Nature saying that methane leaks from US natural gas fields may be anywhere from two to three times as large as previously estimated.

41Audi building e-gas plant to make climate-friendly vehicle fuel

On December 13, Audi celebrated its synthetic methane (e-gas) vehicle fuel plant, which is under construction in Werlte, Germany. Audi says that it is the world's first industrial plant for generating e-gas from CO2 and renewable electricity. Its end product will be hydrogen and synthetic Audi e-gas, which will be used as climate-friendly fuel for vehicles such as the new Audi A3 Sportback TCNG. E-gas production will begin in the spring of 2013.

AddTranslogic drives a poo-powered car

Translogic has driven a lot of interesting vehicles over the past two years. Our sister site filmed some of the first seat time in a Chevrolet Volt, drove Local Motors' Rally Fighter, got behind the wheel of an electric DeLorean, turned in the first test drive of the Lightning GT supercar, tried out the YikeBike, and even found a wacky wood-powered car called the "Beaver." You'd think there wouldn't be anything more outrageous for those guys to find seat time in. Yet they've managed to find yet

AddIn Detail: Bio-Bug

There are some crazy ideas out there on how to power a car. Everything from DIY steam and wood power to OEM-built hydrogen and CNG have tried to knock gasoline from its throne. But could you imagine running your car on the waste that comes from...well, you?

AddVolvo Trucks start field tests of methane-diesel engines

Volvo trucks has announced new field tests of bi-fuel methane-diesel engines in partnership with seven different Swedish companies, adding a new technology to the brand's at-fuel tests with DME and hybrid engines. The new engines, which are based on the Euro-V compliant 7-liter model, reduce fuel consumption by 25 percent compared to standard diesels thanks to methane's lean combustion. The system still uses a small amount of diesel fuel which is injected and ignited by the compression, which in

AddCattle industry has a beef with EPA over greenhouse gases

To the surprise of many, the vast majority of the automakers that sell their wares here in the United States welcomed the EPA's decision earlier in the year that carbon dioxide and other greenhouse gases are damaging to the environment and should therefore be regulated. That has plenty to do with the desire for a single national fuel mileage standard. But transportation certainly isn't the only way we generate greenhouse gases as a society.

AddFiat likes compressed natural gas, now offering 6 different models

Will compressed natural gas soon be a widely used automotive fuel in the U.S.? Probably not, but it could become more common if Fiat's European moves are any indication. CNG is a popular alternative in some parts of Europe and several automakers, including Fiat, offer factory-equipped cars that run on methane. Fiat already offers CNG versions of the Grande Punto, Panda, Punto, as well as the Multipla and Doblò. The Punto and Panda are both expected to form the basis of new small cars for

AddIt's Friday: a peek at the truck stop of the future

What's the price of gas going to be in 2021? Specifically, what will the gamut of transportation fuels cost on March 16, 2021? WIRED recently published one of its artifacts from the future: a truck stop 12 years from now. As you can see in the imaginary scene, a full tank of hydrogen will cost a hundred bucks. Plugging in your EV will cost you $75 a kWh (but the first five minutes are courtesy of GM). Also on tap: methane from Oscar Meyer and Uncle Willie's Kind Green biodiesel. In fact, this re

AddSemi trucks converted to run on biomethane from cow manure

Looking for a sustainable fuel to power your fleet of semi trucks? If you are a dairy farm, we'd bet that the one thing you've got too much of is cow manure. Hilarides Dairy happens to have this exact problem, and it's turning it into a solution. Over 10,000 cows will happily provide enough dung to generate 226,000 cubic feet of biomethane gas each and every day. That amount of gas (literally) is enough to cut 650 gallons of diesel fuel fuel per day from the farm's fleet of vehicles.

AddFordonsGas Sverige creates Svanen, a fuel good enough to be ecolabeled

The world now has its first ecolabelled fuel. Great... what's it mean? First of all, the certification itself comes from the Nordic Ecolabel, "the official Nordic environmental award [that] is given to products and services that fulfill stringent environmental criteria." All right. What's the award signify? "Reduction of emissions that negatively affect global warming and climate change, an absolute threshold value to the amount of CO2 that may be released to the atmosphere during the entire lif

AddMethane from landfills provides fuel for garbage trucks

Talk about going full circle. A garbage truck running on methane picks up the trash out in front of your home and deposits it in a landfill. Over the next few years, that garbage begins to deteriorate, releasing methane gas in the process. That methane waste gas is captured and re-used by the same garbage trucks to pick up your trash. While we aren't necessarily proponents for landfills, at least some good can come out of their creation. Methane gas is a pretty horrible greenhouse gas, so it's m

AddThe possibilities of hydrous methane

Hydrous methane is sometimes called "white gold." But what is it, exactly? It's the result of the decomposition of live matter which is usually stored in non-deep layers of our soil. Currently, the common source is under permafrost. Now, because of an increase in overall temperatures, hydrous methane is being released into the atmosphere, and contributing to the greenhouse effect. There's also a good amount of hydrous methane under the sea inside the upper layers under water. This, some say, is

AddMaking energy from all kinds of crap

Creating methane gas from waste products in anything but a new concept, with the gas being pumped and burned off from landfills the world over. What is a newer idea, though, is taking care of the problem right from the point of its creation... your own toilet or garbage pile. In emerging countries like India, and even in rural areas in the U.S., there are many households which are not directly connected to a sewage system, and there is no big garbage truck on its way to pick up your trash.
