Are you familiar with LFTR and if so can you indicate why fusion is practically superior to it? Cost, fuel availability, safety, vessel lifetime, etc. LFTR scales down, has working examples (fit in a closet in ORNL) fuel availability: lots of thorium, ignition fuel is a problem though vessel lifetime: lots of caustic stuff in LFTR, but fusion is high temperature and will suffer vessel degradation from neutrons, won't it? Safety: LFTR is meltdown proof due to liquid fuel and plugs, and seems to consume all its nuclear fuel (compared to solid rod). Fusion is "clean" but makes the reactor eventually radioactive? Cost: Fusion is a ???, LFTR is undeveloped, and both will be a decade+ down the road during which solar/wind/battery will get substantially cheaper, moving the goalposts for cost/investment.
