I don't know why this isn't the top comment. I came in a skeptic but that video really put to rest my doubts that these new REBCo superconductors are truly a breakthrough. The new designs they enable make ITER look like a massive obsolete waste of time. Sounds like the only hurdle now is 5 billion in funding needed for a prototype. Its no longer "50 years away", its now "5 billion away".
