This video addresses ReBCO superconductors as applied to controlled hydrogen fusion, and this test magnet achieved twice the field strength of traditional superconductors (20 tesla verses 10 for older super conductors) but since this experiment, twice that, 40 tesla has been achieved. The significance of this is that fusion plasma confinement scales with the cube of the magnetic field strength, so a 4x improvement in field strength results in a 64x (4x4x4) improvement in confinement. This allows very small and cheap reactors to be built which in turn substantially reduces both the time and expense of design iterations.
