Alternative Fuels in a Model A

[KGBnut]

I got into an interesting conversation with Pop this afternoon. With the trend toward electric vehicles, the day may come in the future where gasoline is no longer on every street corner. I know that this is completely hypothetical, but as there are fewer consumers of gas and the economies of scale change...the price will go way up, and gas stations may become harder to find than a pay-phone. So, how will we keep our Model As running?

With that in mind I have to ask, has anyone ever successfully converted their Model A's engine to run on alcohol, propane/natural gas, or any other readily available alternative fuel?

I'm curious what's involved. I know that alcohol would require re-jetting the carbs (I seem to remember that alcohol needs to run much richer than gas)? As for propane, can you use a gaseous fuel with a carburetor, or does it have to be fuel injection?

I know it may seem silly, but I'm just curious.
