A well funded government initiative that knows that when they are finished and present their final report they will join the ranks of the unemployed = good for 100 years or more. In truth they have all the data they need to build, small highly efficienct thorium unit reactors in 3-4 sizes combinations of the sizes, with duplicates, would enable Ford style production line assembly of a large proportion of the innards. Cement and steel on site will still be needed. The inherent safety aspects makes it a true winner, and the USA has enough on it's own land for centuries. Fusion is a true infinite boondoggle that will never defeat Thorium or solar/wind. Perovskite-silicon-gallium cells will hit 40% or more within 3-4 years = final death for coal. The whole uranium/plutonium venture was driven by the need for bombs.
