The guys over at Lockheed weren't in charge of one of the leading academic fusion programs in the US. ARC in 2014 was just a design created by students in one of Whyte's classes. At this point, as a woefully ignorant layman, I'm forced to weigh two contrary claims. One is by the head of MIT's fusion program. The other is by a commenter on HN, helpfully linking an impressive-looking paper I don't understand, which does not appear to say with layman-friendly clarity that higher magnetic fields make fusion plasmas less stable.

Hey, I'm not trying to convince you of anything. In fact I couldn't care less what people think of this specific project. It's not my money that these VC funds are spraying. I'm just trying to convey a modicum of common sense when it comes to evaluating sources for particularly extraordinary claims. I see Elon Musk get torn to shreds regulalry around here whenever he says something slightly optimistic about electric cars or rocket science, so I frankly find it astounding how easily people eat stuff that comes from guys behind private fusion companies. I guess plasma physics and continuum mechaniccs are less impugnable than rockets and cars for most people.

  Well I was hoping you were trying to convince me, and would have an easier-to-digest source handy, or a simple explanation of the relevant part of the paper. You certainly don't owe me that, and I don't mean to doubt you, and for all I know you're a professional fusion researcher. Plenty of people like that are on HN. But I don't know, so I'm just muddling through as best I can, trying to get things right. Personally, the claim that stronger fields make plasma more stable doesn't seem all that extraordinary to me, and certainly not one that's contrary to simple common sense. And when it comes to evaluating sources, Dennis Whyte seems like a fairly reputable one.
