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.
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!
