I stumbled across this video today of a lab test of emissions
for gasoline (with 10% ethanol- like is common these days) vs.
E85 which is a fuel only designed to run in some cars, but
apparently burns much cleaner.  I'll admit I didn't particularly
care for E85 before, but now that I see the difference between
it and conventional gasoline... I can't talk E85 down as much.
Even if it contains 20-25% less energy, it still appears to be a
very clean fuel. Ideally, they should have tested based on the
amount of energy present, but I have a feeling gasoline would
still be dirty. The video almost reminds me of the old days of
diesel when it was so dirty... and look how far diesel has come.
From Wikipedia:  E85 has an octane rating higher than that of
regular gasoline's typical rating of 87, or premium gasoline's
91-93. This allows it to be used in higher compression engines
which tend to produce more power per unit of displacement than
their gasoline counterparts. The Renewable Fuels Foundation
