Overall this is presenting a smaller university-class tokamak with advanced superconductors to try to reach Q>2 (scientific breakeven). One of the big advantages of higher fields is that the fusion power goes like B^4. I think this is an interesting idea, but it's hard to imagine the US funding something like this at the same time as ITER. Last year's talk [1] suggests "alternative funding," pointing to other private fusion research, which I am dubious of. There is a mindset that "if these bad ideas get funded, our good idea should get funded more," which we know is not how funding works.
As a former researcher of alternative magnetic confinement schemes, I'm disappointed the latest research in FRCs and mirrors didn't make it into this talk. Viewers should take into account that this, like most talks, is pushing an agenda, in this case a new device called SPARC. It appears to also be a way of using the incredibly talented tokamak researchers at MIT now that Alcator C-Mod is not operating.

Exactly, and it annoyed me a bit the somewhat dismissive tone he applies to the competing ideas. He starts by trying to show an impartial overview while being anything but.
The most interesting thing for these is liquid lithium metal--especially a great solution on diverter. For the wall neutron flux this is unfortunately seen as a "materials issue" (someone else's problem). It is a bit stalled out until we can build something with high enough neutron flux for testing.
Or not necessarily that there isn't any noble intention in him, of course there is some. But, the pressure of keeping funding will always color their presentations, for example, to make them leave out other competing groups and ideas.
