David, thanks for the interesting update. I just looked at two papers, and the figures for A/cm^2 that I saw were in the range of 0.1 to 0.4, so I imagine you're applying sufficient power. Comments inline.

We also have reason to think that hydrogen by itself is not sufficient. We should not assume that the electrolyte does not participate. Some electrolytes and media that have been used in previous Ni experiments are H2SO4, ND4CL (note the deuterium), LiOD, K2CO3, Li2SO4, LiOH, Na2SO4, K2SO4, Rb2CO3 and D2O. > The happenings at the anode only concern me when I detect strange effects > due to the choice of materials.

You may be setting the clock back on your special nickel by cleaning the surface of the deposits. Eric
