I sort of like the renewable fuels concept. Something on the order of methane. That way when you're getting low on fuel you can stop at one of the many roadside dining emporiums, get an Xtra large pizza, a bowl of Texas style chili (with extra beans) a six pack of beer and both you and the car can be refueled in 15 - 20 minutes.

I you can't finish the entire pizza just think of it as the equivalent of a reserve tank of fuel. Save a bottle or two of beer and maybe a small order of beans to go for a couple extra octane points.
