Not an expert at all but this contradicts everything else I've seen on the subject, could you support your claims? I thought there recently were advances in superconductors that would enable way smaller reactor designs?[0]

- pfdietz 6y agoBetter superconductors allow reactors to be made smaller, up to a point. But they still would have lousy power density. ARC's power density (total reactor volume, not just plasma volume) is 40x worse than a commercial PWR. Fusion reactor power is ultimately limited by the need to radiate energy through the wall of the reactor, and the limit from that would apply even if plasma confinement were a nonissue.
