Sorry, I didn't read that far. I guess I just didn't expect you to first propose the platinum treatment as a solution to embrittlement only to then point out the flaw in the process. > >I would also note that adsorbed hydrogen is in an *ionic* state, not >an atomic state. ... nuclei leaving the lattice can grab a free electron on the way out. >The diffusing hydrogen nuclei are principally >ionically bound to conduction band electrons.

The Hydrogen molecule isn't a Mills catalyst AFAIK. However the Hydrogen atom itself may be/is (at least when there are two them acting together, i.e. three individual atoms in all [not two of them combined in a molecule]). >so >ionic hydrogen driven through such a layer could constitute a hydrino >factory. >Once formed, hydrinos should diffuse through the lattice >rapidly.

This I agree with. [snip] Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/Project.html
