Robin, > I fail to see why they would need pure Ni62 for LENR.
To be clear - there is no objective proof that LENR does require or even benefits from any specific isotope. This particular one just happens to be the isotope mentioned in the major claim of Rossi's patent - as being the active isotope for proton transmutation of nickel into copper. It is really the one and only detail which is protected by that granted patent. And there are other reasons to focus on it. Supposedly Focardi came up with the explanation for energy gain via proton plus Ni62 fusion. The particular isotope has almost dropped out of view, as of late, and you never hear of it. Curiously, in the Lugano fiasco five years ago, in spectrograph testing done after the event - it was claimed by the Swedish professors that Ni-62 constituted almost 99% of the recovered ash. That would be astounding if true. Yet, the level of purity the found is identical to the isotope sold by ORNL, leading to the suspicion that the Lugano reactor had been "salted" with the isotope. Rossi was the only one allowed to handle to samples on loading and unloading. I believe this exact detail was poised to be a major part of the legal evidence that IH was going to present - had the Lawsuit gone to trial. That could be one reason that a trial was avoided. We are still waiting for these Swedish professors to duplicate that test in order to prove they were not duped. They promised to do this years ago, but have been silent on the results if they did do it.
