Ethanol Powered Aircraft

We use propane in the balloon. So that's an example of "propane in an
aircraft". The balloon I used to fly has three 15-gal tanks. So each
tank has 75 lb of LP in it. The stainless tanks are quite heavy,
requiring 4 of us to set it up. It's easier when we have to put it
away. Also, in the dead cold winter, a heater must be attached to it
over night before the flight so the LP will vaporize. Just like
preheating an airplane.

I really don't want a Natural Gas powered lawn mower.

Probably wouldn't be any more inconvenient than one of the electrical
ones that require a cord (i.e. not the rechargable battery types)...
I've used air hoses like you use for shop air tools for routing
natural gas to grills for temporary use... CNG (compressed natural
gas) would work, but is not as convenient as LPG...

LPG (aka propane) would probably work since you see LPG powered fork
lifts and such...

Hmmm... A quick search via google shows that it's already been done...
