Re hydrogen as a diving diluent, I have read about hydrogen diffusing through
things. Long ago in a book about iron metallurgy I read that sometimes rolling
a steel bar creates a cavity inside it; in such cavities a little hydrogen is
sometimes found. That is likely because: Hydrogen is electrons chasing round
protons (and a few deuterons) and nothing else at all. There is likely a
reaction H + Fe <--> HFe, with most on the left but yet a bit on the right at
equilibrium. And of the combined hydrogen, the electrons and the protons are
far smaller than the iron atoms and can slip through solid matter, and meet
again and reform hydrogen molecules at the other side.
