This is why I am so excited about Commonwealth Fusion Systems[1] and their SPARC reactor. By using newer high temperature superconducting magnets they can make a fusion reactor with the same Q gain as ITER that is 1/10th the size. Using a tokamak means well understood physics and engineering challenges. They recently proved their magnets work and got 1.8 billion dollars in funding. They believe they can demonstrate the SPARC reactor with net energy gain by 2025 and build the larger ARC reactor by 2030. Maybe it will take a little longer but I’m optimistic it will not fail. My big issues with nuclear fission are the powerful nuclear-capable government required to manage the reactors, the risk of catastrophic meltdown and the national security target reactors become. Fusion just needs duterium from seawater and can’t melt down. [1] https://cfs.energy/technology https://cfs.energy/technology
