Fusion is attractive in principle. It does not generate the same amount of nasty, long-lived radioactive waste that its cousin nuclear fission does. Its principal fuel is deuterium, an isotope of hydrogen that is found in water and is thus in limitless supply. And a fusion reactor would be incapable of having a meltdown. But it is hard in practice. Reactors like ITER, known as tokamaks, are huge and temperamental undertakings. Even when they work as prototypes, they do not look the stuff of commercial power generation.
