  Nuclear energy as a concept is trivial. There are a lot of details between "concept is trivial" and "it's practical at scale"

  > Besides, the concept is trivial and applicable and replicable by almost anyone. Has anyone made one operating at major scale? And comparable to say serious pumped storage? At their page I see only "demonstration unit". I suspect that either it is not solved, expensive or not trivial. And not replicable or there is nothing to replicate or not worth replicating. For comparison https://pl.wikipedia.org/wiki/Elektrownia_Por%C4%85bka-%C5%BBar https://pl.wikipedia.org/wiki/Elektrownia_Por%C4%85bka-%C5%B... can operate at 500MW for 4 hours, was build in 1979 and is a normal pumped storage battery (large enough to be classified, operated and treated as a power plant).
