Oly - i like your idea for a diesel hybrid.. a small diesel motor normally gets 40-60 mpg depending on the engine and driving habits.. a hybrid gas engine gets 40-60 depending on the same factors.. combine the two, and i could forsee over 100mpg being easily achievable, with a very drivable car. I would love to have a 500 mile range with a 5 gallon diesel tank.. your lookin at less than $20 to fill up!

Tanto - Europeans have other stuff over us as well, like good reliable public transportation systems, that normal everyday people use for their commutes rather than their Escalades ( mobile)

as for radioactive waste, yes its a problem, but the amount created is so small.. For the same amount of energy, a nuclear plant creates a basketball size waste, a coal-fire plant could fill a large football stadium with the coal byproduct. And placing the waste below the crust sounds like a viable option to me if they can figure it out..
