"Scientists developing a compact version of a nuclear fusion reactor have shown in a series of research papers that it should work" So they've got a flux capacitor diagrammed on some TP and they're raising a Series B. But we need more of this! https://www.nytimes.com/2020/09/29/climate/nuclear-fusion-reactor.html?action=click&module=News&pgtype=Homepage …

I attended a talk by this Prof, Dennis Whyte, it's a legit project, it's basically a high magnetic field Tokamak.

I'd love to see it, don't get me wrong. But unless I'm mistaken, we have seven research papers saying "theoretically this should work, given our assumptions." Which is a credible pitch, given where it's coming from, but still there is a looooong way to go

100% you're right about that, scaling in fusion is very non linear and instabilities can crop up in many places. And ignited plasma is also very different from any regime in which we have yet operated *but* this is about as mainstream as alt fusion projects get.

it's a heavily studied, most successful geometry (tokamak) combined with high B field from superconducting magnets, which they spent most of the past decade getting experience with

If there is one key to unlock the end of the great stagnation, it's this. The government should be pouring hundreds of billions into plasma physics research. Alas.

I like fusion for propulsion, wherein you can get order of magnitude enhancement in mission profile due to the rocket equation, rather than fusion for energy production, wherein you are competing with fuel to produce heat. https://twitter.com/DanielleFong/status/1223365832631189504?s=20 …pic.twitter.com/7HzWFpKaLz
