I get the impression that the author is painting things with a very, very broad brush. For starters, not all ethanol comes from corn, and thus ethanol does not necessarily drive the price of food up. What about miscanthus? There are MANY ways of producing ethanol, and though producing ethanol from corn is alarmingly inneficient, that does not mean ethanol per se is a bad idea. Either the author did poor research, or he is willingly distorting the facts... Moreover, if ethanol is destroying engines, then that only shows how incompetent some people in positions of power are. I am quite surprised that the author failed to mention Brazil, where ethanol has been used as fuel since the 1970s: http://current.com/items/89112645_the-worlds-sugar-daddy.htm http://current.com/items/89112645_the-worlds-sugar-daddy.htm What the Americans should have done was to consult the Brazilians and ask for advice on how to transition to E85, something Brazil has over 30 years of experience in. If engines need to be modified in order to allow E85, why hasn't the public been informed?
