Your opinions on Tokamak Fusion reactors?

Commonwealth Fusion and SPARC have a good shot. Very little progress this year though.

I wish ITER hadn't been intentionally kneecapped by unite-the-world-through-science bullshit.
We've been on the verge of fusion power plants since the 90s and we've just wasted so much time and money because ITER is set-up so retardedly.
At least they're back on their lumbering schedule now.
Also there's a bunch of good looking startups offering some alternatives.

Iter is already outdated

3 major fusion hurdles
>keeping the reactor from burning up from neutron radiation
>exhausting elements heavier than helium while running.
>adding more hydrogen while running

despite all roadblocks they STILL show the best results and thus humanity best chance to get fusion

Sparc has a good concept with using a lithium blanket that can be easily removed.

Just how far off of having useful fusion power plants are we?
I feel like this is pretty much the only way to overcome a lot of the long term resource and environmental issues that we're facing.

they're quantitatively the best approach to fusion out there right now. There's no other fusion approach that produces neutrons like they do.

Assuming a single country will build it and not the ITER way, I say we are around 30-40B in construction costs away from a prototype, unless some new problems arise, which they always do. For example just now EU is preparing to build a whole new tokamak in Italy just to test new divertor schemes, since if i understand presentation correctly there is non,
0 chance that scientists fucked up previous calculations a bit, and heat won't be spread out enough.
$30B per plant makes fusion completely uncompetitive.
