I found this quote... interesting: "I'm absolutely convinced that without putting any more land under agriculture and without changing our food production, we can introduce enough ethanol in the U.S. to replace the majority of our petroleum use in cars and light trucks."

My first question is 'where will the water come from?'

I'm all for these kinds of things if they can be done properly, but the article seems a bit overly bright and optimistic. Maybe I'm overly pessimistic.
I seem to recall a thread on this a few months ago- what needs to be done to a WBX to burn ethanol properly? Higher compression...? 
This brought to mind the Zetec conversion, among others- what are the current conversion options that will handle ethanol readily?
