[time-nuts] Re: hydrogen rich environment and oscillators

[Dr. Geophysics]

There has been a lot of work with respect to hydrogen sulfide interaction
with steel in the hydrocarbon area.

Hydrogen embrittlement might be a useful search term for your
investigation.   A believe that the American Gas Institute (AGI)  did a
couple of webinars about this topic.  You can probably find them online.
They were quite informative.

Be extremely extremely extremely cautious working around hydrogen.
