TLDR: tokamak type reactor, produced a lot of energy (69 megajujes - nice!) but still net negative.
How much is a megajuje to a megajoule? /s
1.21, I think. You'd have to ask Doc Brown.
69 megajoules is about half a gallon of gasoline
That's awesome, do you have any take on helion's approach to cracking fusion?
Not like I’m an expert on the topic lol. But I happened to watch a Nebula video series on Helion’s approach from Real Engineering and I really hope they manage to crack the efficiency barrier. The idea of truck container sized reactor that makes it’s own fuel and produces energy directly from electromagnetic impulses (not from heat via turbines) is almost too good to be true.
Of course! Was just nerding out. It does seem like they have a lot of barriers to a net positive reactor but it definitely seems like one possible way we could do it!
