      Maybe (or at least an albecuire drive)

      Maybe

      Probably not

      Also some more “basic” things like cheap MRI without requiring helium (which we are running out of), cheap and easy magnetic levitation (more available high-speed trains)

        Last I checked, alcubierre drive still requires negative mass, which is not a thing. Time travel and artificial gravity are still theoretically impossible.

          Yeah artificial gravity I was thinking more along the lines of faking it via magnetism.

          Albecuire drive I was just wrong about, you’re right it’s not a maybe it’s a nearly 100% no lol.

          Sorry just excited.

      no

      no

      no

      this thing would enable very strong superconducting magnets to work without cryogenic cooling. so, portable MRIs, better maglev, maybe perhaps easier fusion.

      another interesting property is that resistance is zero. that means that you can transfer energy losslessly, saving some 10% of it this way. or you can make coils of this thing and charge/discharge them as needed, but this time without cooling: https://en.wikipedia.org/wiki/Superconducting_magnetic_energy_storage
