Scientists and engineers at the University of Arizona are on a mission to develop sustainable agricultural biofuel field crops for Arizona and the desert Southwest – crops that will fuel a new industry as well as America's engines.  Biofuels – fuels developed from biomass such as sugar or grain crops or algae – have as many and diverse uses as traditional energy sources and could be used more widely in the future to power many technologies including automobiles, homes, industrial manufacturing facilities and airplane engines.
