This interesting news about a collaboration between MIT and Commonwealth Fusion Inc (at Nature and potentially behind a firewall for some readers). In any case, the key idea here is that a new generation of superconductors will be used to create a magnetic confinement for the hot fusion plasma.
Many years ago, before I went to graduate school, during an internship on the Hill, I got very interested in fusion. But that was several energy crises ago. These days I would be interested in fusion power as a potential play for mitigating climate change….or possibly Bitcoin mining (not).
