Just get rid of the lobbyists promoting corn for ethanol and allow sugar cane or switchgrass for biomass to distill. Energy out of corn against energy in is 1.3 to 1, sugar cane is 8 to 1, switchgrass is even better than sugar cane but I don't know exactly how much the ratio. Brazil has been doing ethanol since the 1970's for etiher 100% ethanol fuel, or 100% gasoline, or ethanol/gasoline blends. They think America is crazy for using corn to distill into ethanol for fuel. They have mostly subsidized ethanol. But, they now let gasoilinge and ethanol compete and most all their vehicles are flex fuel types now than can burn either 100% ethanol, or 100% gasoline, or a blend of both. The last few years their even offering diesel with ethanol in it.
