So helium is a limited resource. Okay gotcha. So why not take two hydrogen atoms. Take their protons and neutrons. And just fucking start squeezing them together until you get helium?
And I don’t mean in the same way you get H2. Those are still separate from each other.
Not really, but another massive international project, ITER, is trying to do this. Its timeline is measured in decades if not the better part of a century.
