[QUOTE] I guess it comes down to miles per gallon-of-what. We postponed breeding new dinosaurs, so eventually we'll be stuck with energy from non-petro sources. I bet you're right about lower mpg's; but if it comes down to a choice between 30 mpg on a fuel we've exhausted or 10 mpg on distilled dandelions, we'll have to go with the dandelions... ... in which case Scott's will come out with a lawn product that gets rid of all that ugly grass among the dandelions. :-) Brent[/QUOTE] Well, the other thing is that burning ethanol is a bit cleaner than the petro fuels, so you'd think the Earthy Crunchies would be rallying for it! Instead we go for Hydrogen, which is just as difficult to produce, is a LOT more dangerous and right now requires MAJOR engine redesigns! I'll take the dandelions...they make good wine, too!
