No arguement on the nuclear- I'm an engineer, I like thier safety record, it is as good or better than commercial avaition's. It is just a matter of when they break, people have a knee jerk reaction. That makes them politically... complicated.

As for ethanol, I agree. But a (m)ethanol-based mix with other, higher octane hydrocarbons will extend what we have.

Oh, and commercial deisel is something like 15% biodeisel by regualtion, at least around here. And you can use it to cut home heating #2, of course, which is a lot of the usage of that general weight of distillate.
