Roger, an unsolved issue with alcohol is that smog is produced... I
have not done the reading to see what the solution to that is likely
some form of catalytic convertor so I'm not going to claim it is a
deal breaker, but it is significant...

For the ethanol lovers, I am not against ethanol just against muddy
thinking...
TO get ethanol for vehicles you:
*haul seed and supplies
*plow
*spray pesticides and herbicides
*fertilize
*plant
grow awhile
*knife in nitrogen
grow a bit more
*herbicides / pesticides again
grow awhile more
*harvest
*haul
ferment
*distill
*haul it again
mix with gasoline, or whatever hybrid fuel you make
*haul it again
and finally pump it onto your vehicle

Every step that has an asterisk uses fuel or chemicals or fertilizer
dependent upon petroleum...
The fuel of your grandchildren will be a hydrocarbon product made from
coal, not corn...
