1. They don't value the high portion feed left over, it appears they think it's thrown away.
2. At leas one of the tests put a value on sunlight used to grow the corn. Well, the sun shines at no out of pocket expense, so that is pointless.
3. The studies use 20 year old data. Ethanol production has risen from 2.5 gallons per bu to 2.8-3 bu per gallon. Plus they have lowered water use in the plants, plus energy use, plus most now extract oil from the corn for another energy-rich product.
4. If you trace it back, the anti-ethanol studies come from the Big Oil states. This is all politics, pure and simple.
5. Ethanol no longer has a subsidy, ended over a year ago. ethanol uses far less of your tax dollars that petrolium does, so if your tax dollars worry you - as they should - be mad at Big Oil, not ethanol.
6. Real studies of actual inputs and outputs of ethanol production from Midwest corn shows you gain a net energy gain of 25 to 30%. That is not awesomely great, but it certainly is a net positive gain in energy, and means less petrolium is used with ethanol.
There really is no argument here. Some folks prefer supporting Big Oil, some prefer supporting a tad cleaner air and a tad more USA created fuels.

I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
