On the Moove

Professor Eric Leonhardt and his students at Western Washington University's Vehicle Research Institute have built a hybrid car that gets the equivalent of 94 miles a gallon while using a fuel made from a plentiful local waste product: cow manure. The most revolutionary aspect of this research isn't the source of the fuel or the mpg, however. It's the biofuel's projected equivalent cost per gallon: about $2.50.
