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.
Technically, we only kinda just did. We’re experimenting with it currently on a very small scale, and will be scaling it up over the next 10 to 20 years. It’s very exciting time for nuclear fusion!
