Yes, the article also referenced other researchers that disagreed
with them. Opinions vary I guess, but it's a good question to
ask before charging off down the bio-fuel path. Not sure what
motive they would have to intentionally falsify their work,
though. Maybe they were scared by a tractor when they were
young?

Seems to me that there is the possibility of a positive energy
balance because of the solar energy input, but there are a lot of
energy costs as well. I was susprised at the amount of natural
gas that is used to make fertilizer.

One of the other items in that article that caught my eye though
was the claim that if all of the US corn crop was converted to
ethanol, it would only replace 12% of the gasoline that is used.
I'll have to look up an estimate of how many bushels are
harvested to check that.
