For anyone interested in small fusion reactors there is another startup called Tokamak Energy with great Youtube channel: https://youtube.com/channel/UCuSlFJbBUIj1zfJLRnGXSow
I'm hoping to try for a density record with my prototype. It may not happen, but I think I can get higher densities than NIF.

Also the fusion subreddit is reasonably active :

For anyone after an up to date book on fusion The Future of Fusion Energy is good:
https://www.goodreads.com/book/show/43700662-the-future-of-f...
The subreddit is godawful and no one should waste their time.
The book is top notch and everyone interested should give it a read (assuming you care enough and have enough disposable income to afford it, it is not cheap).
There is news on that subreddit of all the fusion startups, even the lesser known ones like HB11.
The Kindle version of The Future of Fusion Energy is $US 12.
Anything funded by DoE (which is a lot) necessarily has to keep all publications public. Just because you don’t have a subscription to Nuclear Fusion or IEEE Transactions on Plasma doesn’t mean you can’t learn about what’s going on for free. It’s unfortunately just a pain to find. Look for papers hosted on websites of projects at PPPL, ORNL, UWisc, IPP, etc.
