>When fossil fuel crude gets really scarce you would need an impossible amount of surface space required to grow all the corn necessary to >accommodate the US fuel demand much less the rest of the world. >Even if you had the surface space on the planet, planting that much of a single crop creates a biodiversity nightmare. Take a step back,,, you're thinking that Alky (ethanol) is only made from Corn. It can be made from MANY sources. Check out this site,, http://running_on_alcohol.tripod.com/ or just google "make ethanol". It came back with 957,000 hits! And who sez it has to power ALL the vehicles?? There's room for some gasoline AND biodiesel in there. There are too many things we NEED petro for. We shouldn't be burning it. Just keep thinking "100+ octane,,13-1 compression!!" It's MADE for us hot rodders!! But hey,,, that's just ME! Bruce Hevner
