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.
Happy trails,
