Exciting stuff. Kudos to this team. Citation needed... If the fusion reactors end up needing tape of room temperature superconductors to keep their confinement going, and they degrade rapidly due to neutron radiation, I could easily see solar being cheaper in the long run. I'm not saying this is exactly what will happen, but I have never seen compelling proof that fusion will really be so cheap in terms of capex or opex per Watt.
