That's an odd passage; who fills their SUV with pure ethanol?
To my knowledge, nobody. So why use that as a statistic?
I'd like to make clear, however, that I'm not really a supporter of corn-based, non-cellulose ethanol production. It's about the dumbest way to make ethanol that anyone could think of.
edit: I forgot to add, the rise of worldwide food prices across the world has MUCH more to do with the currently liquidity crisis in international banking, then it does with the increase in Ethanol production. The rising price of Oil also has a lot to do with it; it's simply more expensive to run farm equipment then it used to be, regardless of whether or not Ethanol production is affecting the prices.
