Biofuels are increasingly lumped into a single category of environmentally apocalyptic dead-end solutions. As the food vs. fuel debate rages on, it’s no wonder that the general public believes this.
But not all biofuels are created equal, as the chart above illustrates (click the image to see full size). It’s one of the best depictions I’ve seen of how each biofuel feedstock has completely different impacts on overall greenhouse gas emissions, water and pesticide use, and the energy required to produce the fuel.
Homemade ethanol guru Floyd S. Butterfield and Silicon Valley entrepreneur and innovator Thomas J. Quinn want to see you making ethanol in your backyard. Their creation, called the E-Fuel 100 MicroFueler, is a stacked washer-dryer sized reactor that can convert sugar into ethanol for (they claim) $1.00 per gallon.
Before you get too excited, please note that the unit is probably too expensive for your next block party, unless you’ve got an extra $9,995 lying around somewhere. Fortunately, state and Federal tax credits can halve this, but that still keeps it out of the price range of the average American.

Last week’s topic was why corn ethanol is an environmental loser.
But are all biofuels losers? No. Some can be winners. One of those is called cellulosic ethanol.
What Is Cellulosic Ethanol?
All ethanol — whether it is corn or cellulosic — is the same chemical compound: C2H5OH. You might recall from elementary chemistry courses that the “OH” group at the end of the formula indicates that the compound is an “alcohol.” Alcohols can have varying numbers of carbon atoms. Alcohol with two carbon atoms is called “ethanol.” The other alcohols are generally too toxic to be ingested, and thus ethanol has been the libation of choice down through the ages. (Ethanol used as fuel is rendered nonpotable.)
So corn ethanol and cellulosic ethanol don’t signify different types of ethanol, but rather the different material (or feedstocks) used to produce them.
300 garbage collection trucks in California will soon be fueled by the same trash that they haul. Landfill gas will be purified and liquefied, producing up to 13,000 gallons of liquefied natural gas (LNG) daily.
This facility at Waste Management’s Altamont Landfill in Livermore, California will begin operation in 2009. It comes with a price tag of $15.5 million, with grants providing $1.4 million.
Cleaner Fuel
Waste Management is the largest waste management company in North America and operates the largest US fleet of heavy-duty collection trucks. The company has a goal to reduce fleet emissions by 15% by 2020.
AutoblogGreen reported today that the cellulosic ethanol company Mascoma has received another $10 million for research and development from Marathon Oil. This comes after GM’s undisclosed equity share in the same company was announced last week, and puts the grand total raised in this round of financing at $100 million.

May 6 was World Asthma Day. Since car exhaust can lead to asthma as well as global warming, we thought it would be a good day to highlight the importance of not idling your car or truck engine.
What makes idling especially bad for health is that drivers tend to idle in gathering places - by sidewalks, schools, playgrounds, homes, and offices. Breathing in pollution close to the source is more dangerous than farther away.
Take a look at the evidence.
Clean Burning Natural Gas Vehicles (NGVs) are hot commodities in some parts of the country, where fuel can sell for as low as $0.63 per gallon.
Unlike the world’s most fuel efficient car (VW’s 285 MPG bullet), the Honda Civic GX looks like a standard passenger vehicle. What makes it special is what you don’t see: tailpipe emissions that are often cleaner than ambient air.
The Civic GX is powered by compressed natural gas—methane—the simplest and cleanest-burning hydrocarbon available. With an economical 113-hp, 1.8-Liter engine, the EPA has called the Civic the “world’s cleanest internal-combustion vehicle” with 90% cleaner emissions than the average gasoline-powered car on the road in 2004.
And get this: in Utah, natural gas can be purchased for $0.63 per gallon.
…or so the media has us all believe.
About two weeks ago, the Government of Delhi, India unveiled the much hyped Bus Rapid Transit (BRT), previously popular here as the High Capacity Bus Corridor (HCBS) and the construction for which had been on for the last few months. The little under 6 Km BRT stretch that is now completed and is being trial run came at the cost of some lives (accidental deaths) and at the reported cost of about 3,000 heritage trees of Delhi. The dedicated bus lanes invited mixed reaction from the public; with the car users complaining about having to spend more time on the road now than before and the bus riders being annoyed with the bus-stands being displaced to the middle of the road. Poor design and lack of coordination between different stake holders further worsened the situation. And as if all of that wasn’t enough, the media has taken on itself to narrate the “failure of BRT story” with much fervour.
Yabba dabba doo! Thanks, as always, to Brad and Peter for allowing us to republish “Shades of Green.” You can find more of their work at The Green House. And, of course, there’s always more on alternative transportation at Gas 2.0.
Electric and hybrid electric car manufacturer Aptera has been turning heads since the first announced their space-age looking Typ1 prototype. The sub $30,000 electric version of the Typ1 has a range of 120 miles and is expected to be ready for limited release later this year.
Take a look at the latest video from Aptera, a guided tour of their factory:

General Motors announced today it would be entering into a strategic relationship with Mascoma Corp., a second-generation biofuel company with the technology to produce cellulosic ethanol from non-food sources via a single-step biochemical conversion.
The undisclosed equity share aims to contribute to joint research and development along with technology exchange, plant siting, and rapid commercialization of cellulosic ethanol technology and infrastructure. This is GM’s second investment in a cellulosic ethanol company, after announcing partnership with Coskata back in January.
