Alcohol does run cooler, and cleaner.
However, It requires just about twice as much to do the same amount of
work as gasoline.
So the pilot, and main jetting would basicly have to be almost twice as
large to allow for the correct volume of fluid to run through them to
get the job done.
We're almost talking 4,5 mpg with the alcohol.
I don't think the Digijet,or Digifant would be able to handle the
correct volume of fluid required to make the engine run right.
We'd be all back to carbs with big jetting.
