Thanks for bringing this up. I think it is important. Table 10 from Miles is the most dramatic proof that so-called Type A Pd is particularly effective. It is easier to see this in my version (which has a link to the original), p. 6:

You can find it in Storms book. > Ed wants SMALL cracks. Microscopic cracks. The ones that form in bad palladium are macroscopic, or nearly macroscopic. When the cathode is deloading, you can see a line of large bubbles form at one of these cracks. Also, a Pd rod may visibly bend. Materials that distorts, pillows up, or bends probably will not work. See: http://lenr-canr.org/acrobat/StormsEhowtoprodu.pdf See also this paper I translated the other day, which is not about cold fusion *per se*: http://lenr-canr.org/Collections/JungDamagemechanism.pdf (I uploaded the text from the first Jung paper here.) > The ammonia atmosphere leaves a population of hydrogen in the palladium > which controls recrystallization.

It works as a filter just as well as the old material did. Martin did not know if it would work or not. McKubre told me they tried some and it worked well.

I doubt they could even make a batch of the original material now. The equipment must be scrapped by now, and the people Martin knew there are long gone. I heard that the new method wastes less Pd and it is safer. I suppose the purity is same or better. Martin told me the original material and method was developed back in the 1930s. - Jed
