Materials- yes that is an important part of it all.
I started with palladium fountain pen nibs (way back in 89) - Schaeffer “snorkel” – it is what I could get back then. You get higher power density with "3 or 4 nines " palladium (but the really pure stuff 5 nines doesn't work very well ??) but if it is replication (at lower densities) you seek- try the Pd 23% Ag material used in diffusion systems. If you have the ability to alloy your own, I would recommend Pd 10% Y or Pd 2% Ce to start with. The Y alloy has about 3 times the diffusion rate and is quicker to load. Be sure to load slow, cool and for a long time (see paper- DO NOT RUSH LOADING). There is some evidence that loading Pd at around 10C helps (it matches the vacancy sizes and the wavelength of the D) Then raise the current density and temp (best run over 65C). I wish you luck and patience. We need more serious experimenters. (if you use Pd sheet- look over the 17 step protocol Letts and I disclosed in 2003 at ICCF10- It is lengthy but it seems to give reasonable results) Best wishes,DennisDate: Tue, 14 May 2013 12:28:25 -0400 Subject: Re: [Vo]:If I want to see it for myself...

Also: http://www.lenr-canr.org/acrobat/StormsEhowtoprodu.pdf However, the key thing is to get good material, and that is not easy. The ENEA makes it, but they only share it with accredited university and national labs. I suppose you might try some Johnson Matthey hydrogen filter palladium. As I said, Martin recommended that. It was the old formula. Perhaps it had trace elements in it that enhanced the reaction. It had more impurities than the modern version. I do not know anyone who has tried the newer filter palladium. It might work just as well as the old stuff, or better. I would like to find out. Tanaka Precious Metals might be interested in a cooperative set of experiments. Bear in mind that the procedures described by Storms take considerable expertise, and a lot of time. About a year. He started with ~100 cathodes and winnowed out 4 that worked well. (I think it was 4 . . . I am not in my office so I cannot consult my notes.) These 4 worked consistently and repeatedly. I think it is fair to say as a result of these tests, reproducibility increases to 100%. You have to leave behind ~96% of the starting cathode material, but what you end up with always works. As you see in the paper, the winnowing process does not involve simple trial and error cold fusion electrochemistry. It is as if Storms runs 100 cells to find 4 that work. He does other diagnostic tests that tell him in advance whether cathode will or will not work. These tests are similar to the ones recommended by Cravens. - Jed
