It's this kind of story that gives me faith in America -- again. An innovative mechanic in Kansas named Jonathan Goodwin is inventing new ways to get double, triple, or quadruple the mileage that big cars (such as Hummers) can get out of fuels, using innovative methods but basic parts, usually made by GM.
He is a virtuoso of fuel economy. He takes the hugest American cars on the road and rejiggers them to get up to quadruple their normal mileage and burn low-emission renewable fuels grown on U.S. soil--all while doubling their horsepower. The result thrills eco-evangelists and red-meat Americans alike: a vehicle that's simultaneously green and mean. And word's getting out. In the corner of his office sits Arnold Schwarzenegger's 1987 Jeep Wagoneer, which Goodwin is converting to biodiesel; soon, Neil Young will be shipping him a 1960 Lincoln Continental to transform into a biodiesel--electric hybrid.
His target for Young's car? One hundred miles per gallon.
