ethanol? pretty much the only economical way. economic alcohol from
cellulose would be a major breakthrough.
the brazilians use bagasse (cane sugar waste) to make alcohol, but you
run into the same economics.

methanol from coal is doable, but its also an energy intensive
process.


Save the corn for the cows.

yeah, but you need garbage in the first place. you will always get
out less energy than the energy put in to make the product in the
first place.

If you're using enzymes/microbes to break down waste cellulose, that
otherwise would have been burned because of excess, then you're getting a
net gain of usable energy that you otherwise would not have had. And as far
as the OceanEthanol process, you could use wind and solar energy to separate
the hydrogen and oxygen from the water, then use carbon dioxide from exhaust
or the air to create the alcohol. It's easier to store than hydrogen or
electricity. The byproduct is oxygen. Can't beat that!
