Uhnnn... Unless USA have a secrete technology to much higher & easier corn production compared to Brazil, sugar cane it's more effective, otherwise Brazil would use corn, since Brazil also have a very high cattle and vegetable oil production for exportation.
USA, few years ago, was interested on Brazil's sugar cane ethanol production.
I wonder how many cars could they move if was possible to collect methane from cows.
One key points of genetic engeneering, for Global energy and fuel, it's about the possibility of develope a genetic modify yeast, able to fast breakdown cellulose. If they managed it, everything from corn, even the cob and atraw, could be turned into ethanol. Even old wood and dry grass removed lawn mover.
By the way, just for brazilians : Joćo Doria would try to feed the poor using corn destilation leftover, if Brazil had a corn ethanol program.
I wonder how a process like liofilization, that in most cases make the food a lot more expansive, since the process it's more expensive than the food itself, could be used to make free food (close to expire and donated) economically worth to help the poors.

Weight gain on beef cattle fed with distillation grain is higher than for cattle fed with raw corn, and also leads to lower methane emissions originated by the cattle' burps and farts (it sounds quite dumb, but that's one of the subjects of complaint of the veganazis regarding the environmental impact of the meat industry).
