Nice art, but now imagine a large number of very modern nuclear reactors, hidden away in industrial areas like other industry, generating massive amounts of power, consistently. And of course, capturing all its toxic outputs and barreling them up, to be re-enriched at least once. At that point it's a trash handling problem, which pretty much every single other form of energy completely ignores. What happens to old solar panels, old wind turbines, what happens to the exhaust gases and particles from burning coal, etc? What happens to old batteries?
