ABSTRACT
Those words, which perfectly capture the sense of excitement and potential surrounding biofuels today, were actually spoken in 1925 by Henry Ford. Some of the earliest motor vehicles developed by Ford and others ran on biofuels-on mixtures of ethanol and gasoline for the early spark ignition engines and on peanut and hemp oils in Rudolph Diesel’s earliest compression engines. Today, following an eight-decade detour in the petroleum age, biofuels are back-fueled by a powerful combination of advancing technologies, rising environmental concerns, farmer support, and soaring oil prices.2
