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

[–] [email protected] 1 points 8 months ago

69 megajoules is about half a gallon of gasoline

1.21, I think. You'd have to ask Doc Brown.

That's awesome, do you have any take on helion's approach to cracking fusion?

[–] [email protected] 5 points 8 months ago (1 children)

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!
