David Pemintal doesn't seem to be providing a very balanced picture if you ask me.

I found this simple description of how the processing works. Ish tells me that ethanol is produced from the waste products of corn production. If so, that deflates much of Pimental's argument about the costs of growing the corn. In addition Pimental argues that costs for other corn uses (feed for chickens etc) are affected. A while back I heard we are subsidizing grain farmers not to grow so much because we end up with a huge excess. Is that still true?

"6. Dehydration: The alcohol from the top of the column will then pass through a dehydration system where the remaining water will be removed. Most ethanol plants use a molecular sieve to capture the last bit of water in the ethanol. The alcohol product at this stage is called anhydrous (pure, without water) ethanol and is approximately 200 proof."

It is a fairly new and developing industry. There is a lot of controversy over the cost/benefits of the whole thing. But keep in mind, if cars had been required to be as efficient as horses when we rolled the first automobiles out, we'd probably still be saddling up to go to work pardner.

Yeehaw,
