<<What I've read is that it takes a gallon of gas ( counting all the farming, fertilizing, processing, transporting, etc. ) to get a gallon of ethanol from corn. Sugar cane is MUCH more productive, which is why it works in Brazil.>> They use the whole sugar cane plant. Corn is processed to remove proteins, nutrients and corn oil before the remaining starch is converted into ethanol.

Even if corn is producing 70 gallons of fuel per acre, how many times is that acreage available a year? Once? I still see us requiring every single acre of the US of A planted in corn and that still doesn't address the problem of ethanol being less efficient than fuel (so you need more to do the same amount of work) and the problem of the fuel required to make the corn in the first place. This is turkey induced calculation so take it for what it's worth...burp. US requires 500-700 million gallons/day Using the lowest number that still requires over 7 million acres of corn at 70 gallons/acre and that's every day. That's 2.5 billion acres per year and that's larger than the US of A.
