"Grass Gas" Shows Promise as Superefficient, Clean Fuel

Sometimes I wish I'd never taken up this biofuel topic. Once you start, it seems you can't stop.

Anyway, this sounds like a much better idea than making biofuel out of edible crops which is already adding to food costs and shortages.

You don't eat grass do you? Just asking.

Ethanol made from a prairie grass shows promise as a viable fuel that could be much more environmentally friendly and energy-efficient than corn ethanol, a new study says. Ethanol is often touted as a cleaner-burning gasoline alternative that lessens dependence on oil.
