I'm curious as to how much deuterium might be used up. Hydrogen itself is too stable. According to theory, one cannot get two of those to fuse..but instead, a heavy hydrogen (deuterium) fuses with a hydrogen atom. Or so I understand, what is said to take place inside a star.
Some other ancient alchemy-like text spoke of taking the lighter (in their eyes more noble) "air", and "casting it to the ground".
What the heck was all of that about? Are we seeing something like it, now?
...but I was hoping folks would go to his article...
