Helios is building real facilities. Maybe it won't work, but it's not just drafting CAD templates — they are deploying capital into physical reactors. That's not bullshit.
Not only that but the reactor they're building now is their seventh. They kept their previous reactor under vacuum for 16 months, did thousands of fusion pulses, and achieved 100 million degree plasma temperatures.
