Fill ‘er Up, With Microbes

[Hydrogen] The car you drive in the future may well be powered by the breath of tiny living organisms. That’s the promise, at least, of a new field of science known as biological energy production. Researchers in the field seek to find a cure for the world’s dependence on fossil fuels by taking advantage of nature’s ability to transform sunlight and simple sugars into usable fuels. And as their early successes with microorganisms indicate, they’re on the right track.
