Well the silliest part is that corn is about the least efficient way of making alky. Takes about 4X the weight of corn compared to Sugar Beets or Sweet Sorghum.


Brazil has been running without gasoline for many years but the climate is suited for the high yield crops.


Final thought: alcohol does not cause rust, that takes water usually in the form of condensate. What alcohol can do is to remove some coatings and expose steel to water and air. If the tank is kept full, condensate will not form (or will be reabsorbed into the gas).


So not all bad, just very inefficient. And since my Jeep is flex fuel, if gas gets scarce, I'll just build a still and reprogram the Reattae to be about 30% richer. (heat of combustion is a lot less).
