While you’re probably right about GP’s cynical tone, this announcement does seem fairly meaningless. Does Helion have a working prototype that can be reasonably moved into production? Or is that still years away?
> Their sixth reactor achieved 100M degree temps, ran for 16 months under vacuum, did thousands of fusion shots, and demonstrated D-He3 fusion.
I don't have anything near the expertise to evaluate Helions approach, but I know enough about fusion to say that just because you have a design that can achieve fusion conditions does not mean the approach could even theoretically lead to a power plant. e.g. electrostatic fusors
Lasers are really inefficient (poor at transforming electrical energy into light energy). They got more energy out than they put into the pellet, but nowhere near as much energy as they put into the lasers. Which means that turning that experiment into commercial fusion is... "not straightforward".
NIF's lasers are only 1% efficient but they date back to the 1990s. Equivalent modern lasers are over 20% efficient. If they had modern lasers they'd have produced fusion power of about 20% of the input power.
They seem to scale well, too. In their big shot they increased the laser power by 8% and output went up 230%.
That said, compared to Helion it'd still be a lot harder to make a practical reactor with NIF's approach.
In a world drowning in self-interested promotional 'puffing," calling this cynicism is in itself cynical.
I prefer to see what your referring to as HN's community hype-filter.
