Most people would agree that the United States needs a new source of fuel: something renewable and nonpolluting with which to replace gasoline … something that could be produced right here at home. Deep in America’s heartland, a lot of people think they know the answer: ethanol, a fuel made from fermented corn.

It was one of those things that you can’t quite believe is real. I was flipping through a magazine and saw an ad for a stove that burns corn kernels. For heat. Corn is food, not fuel, I thought, but the ad assured me that “Corn is replenished annually. It is a never-ending energy source, and thus is the new alternative fuel of choice.”
Discovering an affordable and cleaner burning alternative energy source has long been the dream of industrial chemical engineer Robert Manurung.
Strongly reasoned case put for biofuels as the solution to decline of fossil oil supply. Dr Chia (cardiologist) calmly lays out the Hubbert/depletionists case, dismisses any central role for nuclear energy, and goes on to advocate bioengineered phyto-fuels (for biodiesel etc) and the development of artificial photosynthesis.
Penn State environmental engineers and a scientist at Ion Power Inc. have developed an electrically assisted process that enables bacteria to coax four times as much hydrogen directly out of biomass than can be generated typically by fermentation alone.
A shift from burning wood to burning charcoal in African households could save millions of lives and substantially reduce emissions of greenhouse gases, say US researchers.
Andres Oppenheimer argues that the US should follow Brazil’s example in starting a massive biodiesel and fuel ethanol industry.
New plants for production of bioethanol fuel entering service in Germany will start consuming significant volumes of grain this year — but only at very low prices, market players fear.
High crude oil prices may have galvanized bio-diesel production, but some questions are now being asked in industry circles about the ethics of using a limited edible resource to meet the world’s energy needs, said an influential edible oils industry analyst.
