Bear in mind that Helion's reactor is 50MW, about the size of three large wind turbines. If it works they'll be mass-producing them in factories and shipping them by rail, and they'll have a declining cost curve just like anything else.

I am cautiously optimistic about Helion. IMO, they're the fusion team that has the best chance of reaching the economic finish line.
