We live in challenging times with enormous environmental challenges. It takes a lot of energy to clean up the mess we have generated over the ages. It would be a shame to use up our remaining coal, oil and gas to produce the electricity needed to clean up. Oil coal and gas will eventually be depleted and we need to save some for our great grandchildren so they can enjoy flying like we have become accustomed to. Like the famous conservationist Sarah Palin once said: “for when it’s gone, it’s gone.”
The need to develop a Thorium based molten salt fast breeder nuclear reactor to develop our energy needs for the future can not be overstated. Lest anyone should be threatened by the words fast breeder, it simply means it uses fast neutrons instead of thermal neutrons, and breeder means it produces more fissible material than it consumes, in the case of Thorium the ratio is about 1.05.
There is enough Thorium around to last for a million years at today’s worldwide electricity generation levels. Uranium is in short supply. The consumption exceeds production, and the worldwide major importer of Uranium is the U.S. (The fact that we sold 20% of our uranium ore to the Russians did not help)
There are of course the sustainable energy sources such as wind, solar, hydroelectric, biomass, geothermal, tidal and wave energy, and they should be pursued where economically and environmentally appropriate. These are a separate but important subjects.
