The development of civilization is demonstrably tied to the ability of a people to tap, distribute and maximize ever growing amounts of energy; this energy powers the production and transportation of goods, frees people to pursue greater scientific and artistic achievement and secures the military and civil security of the people.
Diffuse, environmental energy sources are insufficient to replace the energy supplied by fossil fuels, requiring a renaissance in the US civil nuclear program. Because light-water reactors are inefficient, less-stable and generate a no-longer acceptable amount of radioactive waste, Liquid-Fluoride Thorium Reactor technology is in our national interest to pursue. It is roughly 90 times more efficient in energy yield, vastly safer, and has about 1% the waste.
