Re: F... gas prices
well, nuclear is the cheapest and greenest energy out there, but it won't fuel cars (besides electrics and those batteries aren't any greener than a hummer, BUT at least it could weaken oil prices some).
bio-diesel is nice and all (and way more efficient than ethanol), but once you make it a mass commodity, it's price structure just isn't going to work well compared to right now where you can get it for almost nothing (if you know a mcdonald's manager).
sugar cane based fuel is also much more efficient than corn based fuel where applicable, so ending corn subsidies and expanding sugar cane production can even help a little (and sugar is healthier than corn syrup anyways, and could be cheaper if corn wasn't subsidized like it is now)
