The other day Francesco Celani and his friend asked me if I know of any papers that discuss the role of H in the bulk Pd cold fusion. Can H enhance the reaction? Is there an H-D reaction? I said I don't recall any papers like that. It turns out they already found one, which I added to the library:
Schwinger, J., *Cold fusion: a hypothesis*. Z. Naturforsch. A, 1990. *45A*: p. 756. https://www.lenr-canr.org/acrobat/SchwingerJcoldfusion.pdf QUOTE: The hypothesis that I now advance has the following ingredients: (1) The claim of Pons and Fleischmann to have realized cold fusion is valid. (2) But, this cold fusion process is not powered by a DD reaction. Rather, it is an HD reaction which feeds on the small contamination of D2O by H2O. Ed Storms has often said there may be an H-D reaction, but I do not think he says this is optimum, or that it enhances the reaction. Here is what I wrote back to Francesco: Ed Storms and others have speculated that a mixture of hydrogen and deuterium might produce different products. You can read Ed's papers for details. I do not recall anyone testing this hypothesis. I do not recall reading a paper that suggested a combination would produce better results. Many people have said that allowing hydrogen contamination of deuterium prevents the reaction with the bulk-Pd - D system. Bockris and others said it was important to prevent exposing heavy water to air, because heavy water is hydrophilic. Bockris used to keep heavy water in a medical IV bag (with no air), and he added it to the cell with an IV tube, which is small. You put the valve at the end of the tube, and open it to add make-up heavy water to the cell. Bockris also said that CO2 contamination of heavy water poisons the reaction.
