Personally, I think all of the stimulus money should have been used to build new nuclear power plants. Nice construction jobs, permanent jobs running them, and lots of surplus energy to stimulate a true economic recovery. Could have built 100 or more of them - would have cut CO2 emissions by doubling nuclear capacity to 40% or better of total electrical capacity in one pop. Certainly a better investment than pretty much everything else I've read about, Polywell being the exception.
