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.
You iust described nuclear fusion. We haven’t managed to figure out how to do it in a cost effective way yet.
Controlled and cost effective way. Fusion bombs have been a thing for half a century.
