It is well known that corn is a terrible way to get ethanol and further generation production will use bulk cellulose and plants like switch grass.

Corn was never a good source for ethanol, this makes it look even worse.

Corn ethanol is stupid, but - you know - in some parts of the world water falls from the sky. Water use doesn't /have/ to be bad.

Lack of access to fresh water is probably going to be one of the largest challenges of the 21st century. I don't think this is something to dismiss lightly.

Nuance won't kill you.

And in other parts of the world, ground water depletion is a looming blight that will destroy the local economy in a decade or so. Water use can be bad.

For those interested in the subject: Ernst Weizsäcker, former Dean of the Donald Bren School for Environmental Science and Management at the University of California, has some interesting articles on resource productivity on his website: http://ernst.weizsaecker.de/

Buffet wins again - he said this Ethanol thing wouldn't work.

Just a pile of politically correct crap. Lotsa good booze wasted, in my opinion.
