So, make ethanol from sugar, not corn. And use an osmotic process to
distill it instead of a thermal process.

Whoops, sorry. I forgot about the sugar lobby. Our domestic stuff is far
too expansive to use for motor fuel. Using world sugar prices, the
estimate is about $1.00 per gallon.


Certainly sugar beets are a better approach, but please... a citation
that accurately shows cost-to-produce/energy-consumed-to-produce a
quantity with the same energy equivalence as a gallon of gasoline...
data that would possibly impress me more.

Here's some articles about a home ethanol production system:

http://www.ethanolproducer.com/article.jsp?article_id=4169

An NPR reporter dug into the economics of this process. It turns out
that $1.00 per gallon ethanol is possible, but only based on world sugar
prices (not available here in the USA). If you buy sugar in bulk (by the
truckload) US prices, it'll run you about $6.00 to $8.00 per gallon
IIRC.

If I can find a summary of the analysis on-line, I'll post it.
