Better yet, we need to transition from uranium fuel cycle to the thorium cycle. The BIG reason for this is that we can add small amounts of all that waste uranium to the thorium salt reactor to increase the energy output while degrading most of the nasty isotopes. The only reason we ever started with uranium was to make bombs. Thorium was always a better solution for power production not least because it actually degrades to truly safe isotopes. with long term stable heat engines, it should be possible to then supply heat to the urban environment. That is obviously good. We all want cheap reliable heat. Now throw in having atmospheric power generators in all large citrties as well and t
