I asked, but he has not had a chance to respond. When I asked him why he selected that heater, he said, "because it was the cheapest one." It has to be 500 W and heat resistant at high temperatures. I expect any heater that meets those specifications will do. I doubt it matters. That is probably the first time I have said, "I doubt it matters" with regard to materials in a cold fusion experiment. Usually we have no idea what matters but we have to be fanatically careful about sourcing all materials. > > Other thing, can Mizuno provide his supplier of SS316 tube ?

They have thin metal gaskets. I do not recall what metal it is. The reactor has to be airtight enough to hold a vacuum for weeks, and it must not contaminate the gas at high temperatures. That is about all I know about it. I expect any stainless steel reactor that meets these specifications will do. I recommend you test it for a week, baking it out at low pressure and looking for contamination in the gas, using a mass spectrometer. I do not know much about welding, but I do not think you should weld a reactor because I have heard the welds might leak, or contaminate the gas. I suggest you have a reactor fabricated by a specialized company. You might be able to find scientific supply houses that sell off-the-shelf reactors. I have a feeling this experiment is not fussy about the sources of the materials, or contamination. Mizuno is usually very careful about contamination, as are all electrochemists. He seems almost lackadaisical with this experiment. The method of making the reactant seems frightfully crude. I am amazed that it works at all. Yet it does seem to work. If it works, I'm happy, and I am not going to argue with Mother Nature about it. - Jed
