-> I remember reading in older hot rod magazines that alcohol
-> runs much cooler than gasoline...
Well, starting out with the right mixture is a big help.  You've got to
provide some flash evaporation inside the combustion chamber to help
keep the hotspots down, or you can get into some pretty serious
preignition problems.  "Lean burn" aint where it's at with alky as I
understand it.
Besides, I don't understand all this conversion of potential energy that
everyone seems to want to get into.  Lessee, we take sunlight and apply
it to dirt to produce foodstuff, then apply distillation to that, then
internal combust it into rotation, then apply the rotation to generation
to make electricity to do.....?
Every process has some efficiency losses, makes our electricity awfully
expensive in raw material terms, don't it?
