Hi Jim, I've heard about that study, but have not looked at it in detail. But I can tell you this: If you want to know about the legitimacy of a study, look at who produced it and who is quoting it. My bets are that the study in question was done by the petrochemical industry, and being quoted by one of their lobby groups. Any study submitted to the press is designed to support an agenda. That's what they're for. Personally, I would expect that if ethanol actually cost more energy to produce than it contains, the price would reflect that. And I know that even *if* current ethanol production techniques are inefficient, that doesn't necessarily mean that they are going to stay that way as the demand for ethanol increases. Biodiesel is definitely worth looking at, but the cost of re-fitting my aircooled buses to a diesel powerplant is NOT insignificant. And as the cost of gasoline continues to increase I can only expect the cost of suitable donor diesel powerplants to increase. Sigh. I'm only just now getting somewhat proficient wrenching on my gasoline engines. Carbon added to the atmosphere due to transportation technology doesn't care if it's from corn, sugar beets or dead dinosaurs, the end result is no different.
