You've got me wondering how much cheaper ITER actually gets if you don't need the magnets to be cryogenic.

What I wonder if the cooling requirement drops how much easier it is to get to break-even.

What about colliders too?

Imagine large hadron collider without cooling!

We could have the unimaginably huge hadron collider!

I'm already rooting for CFS' Sparc over ITER anyway. ITER is too big & expensive, if Sparc works it's an indication that we can build fusion "on a budget", too.

Idt CFS will care because they've already sourced much of the HTS tape that they need and their schedule doesn't permit waiting for LK-99 to be proven/disproven and all the years it will take to produce LK-99 in bulk anyway.

It's so insanely cheaper, because not only do you not need the cryogenic cooling (and all the support and maintenance systems and consumables like helium or nitrogen or whatever), but LK-99 is made from relatively common elements versus rare earth elements.

I really, really hope this stuff works.
