according to the site:
www.freerepublic.com/forum/a3b74982d5c0d.htm
with this quote:
"acre of U.S. corn yields about 7,110 pounds of corn for processing into 328 gallons of ... energy costs of corn production and its conversion to ethanol, 131,000 BTUs ..."
I calculate about 22 lbs/corn per gallon of ethanol
Sounds about right when you think how much corn you would have to eat to sustain you while you pushed a car for 25 miles.
Thats a joke of course but it does remind us that a gallon of ethanol or gasoline has a huge combustion energy. I have not cross-checked this with other sources but I believe it is close.
