Believe it or not - I've been looking into Ethanol quite seriously.
If you've got a backyard - forget about buying it, you can make your own legally:
How To Make Your Own Alcohol Fuel
or
Great Fuel Making Site With More Info on Ethanol
That's to make 160 to 200 proof alcohol (which will run in a converted engine).
I can also let ya know how to convert your car:
Converting a Carberator Car to Alcohol
If you have a fuel injected car - here's how the University of Texas converted their truck:
Converting a Fuel Injected Vehicle
I'm personally gonna try to convert my GTO to Ethanol - it's got MORE power than gas (it has a higher octane rating), burns cooler, cleans your engine. The only draw back is slightly higher fuel consumption.
Then again, if you're making it in your backyard - who cares!
If you're looking to buy new almost every Ford has a flexible fuel option for E85 - but I still think pure alcohol is the way to go.
