ITER is a showcase ... for the drawbacks of fusion energy | Bulletin of the Atomic Scientists
One may wonder how that expended energy could ever be paid back—and of course it won’t. But the very visible embodiment of the tremendous energy investment represents only the first component of the ironic “Unlimited Energy.”
(…) ITER’s anticipated 500 MW of thermal fusion power is not electric power. But what fusion proponents are loathe to tell you is that this fusion power is not some benign solar-like radiation but consists primarily (80 percent) of streams of energetic neutrons whose only apparent function in ITER is to produce huge volumes of radioactive waste as they bombard the walls of the reactor vessel and its associated components.
