11/19 A good summary of ethanol:
http://www.ce.berkeley.edu/Courses/E11/PatzekEthanolPaper.pdf
\_ This has nothing to say about air cleanliness.
\_ and... as it is right now, it takes *MORE* energy to produce
Et-OH from corn than the energy contained in Et-OH.
\_ Not according to that article. That article plays some
weird sleight of hand by claiming that solar energy is
not free.
\_ He's not discounting solar energy. Let C be the amount
of corn required to produce the equivalent of 1 gallon
of gas in ethanol. He's saying that through fertilizers,
tractors, irrigation, harvesting, drying, and conversion,
1 gallon of real gasoline is used to grow and convert C.
It's zero sum, you could have burned that same gallon of
gas directly.
\_ If you have even one scientific article claiming the EtOH
\_ If you have even one scientific artile claiming the EtOH
does not decrease emissions, I would like to see it. It might
not be worth the cost, but it certainly cleans the air in CA.
\_ Here is a good cost/benifit analysis saying the whole thing
is not really worth it:
\_ ok, here's the deal: gasoline is bad for the environment. the stuff
we add to it doesnt change that much. nothing much will happen
until we get a non-oil based economy going. don't hold your
breath for that one, folks.
