So maybe part of this is already being ready to accept alcohol and then using the acetone/water mix.

I've gotta see if this works. Very interesting. Will have to scout out a donor car.

In the meantime will have to get some acetone and mix with water to see how it reacts/burns/ etc and experiment.

Under normal conditions of many of us keeping a can of gas in the shed for the mower we know how quickly the gas gets stale. The following spring it's less potent than it was during the late summer early fall. I looked up acetone and one site said a shelf life of 36 months. That makes it fairly stable for 3 years? If so that means a vehicle could have a potential 3 years supply of fuel off a quantity bought and set aside provided it was used right after it was obtained.

Ok,,,,off to fiddle with this. i think i might have something I can use for this to try it out
