Detecting the presence of these transmuted elements should be much easier to replicate than trying to characterize "excess" heat, right? And the next step would be to try and find out what isotope of the transmuted elements was? Anyone know how much deuterium costs? https://thenewfire.files.wordpress.com/2020/10/nasa_transmutations_palladium_silver_metals_with_deuterium_gas_2020.pdf https://thenewfire.files.wordpress.com/2020/10/nasa_transmut...

It depends. The transmuted elements could be viewed as contaminants while it'd be hard to explain away excess heat. There are so many sources of potential contamination. Random heat signatures not so much.

  It's the opposite. Heat is notoriously difficult to measure accurately, especially when small amounts are being produced or if the experiment runs over a long time. Heat can also have many sources, some of which aren't expected by even highly experienced experimenters. For example, hydrogen has spin isomers, and the conversion of orthohydrogen into parahydrogen releases energy. Metals like palladium can also release surprising amounts of energy due to lattice or adsorption effects. Graphite absorbs neutrons in reactors and can store sufficient energy in the lattice structure defects that it's a hazard if released too quickly. Electrical interference can produce currents that are absorbed in the metal. Residual magnetic fields release energy if the metal is demagnetised. Etc... Meanwhile, measuring the production of new elements is trivial, even in tiny amounts, and cannot possibly occur via only chemical processes. Crystal structure, phase transitions, external fields, etc... have no effect on this measurement. It is a simple, reliable, accurate measurement. If you see a scientist insisting that you pay attention to the unreliable metric and waves his hands to explain why you should ignore the reliable metric then it's a safe bet that he's either fooling you, or he fooled himself.

    Yeah but extraordinary claims require extraordinary evidence. Right now the easiest explanation is contamination, ordinary and easy to explain.

      No. Claims Require Evidence. Maybe it's contamination. Maybe it is something interesting. Ordinary evidence will reveal which. Demanding extraordinary evidence is just defending turf, and not science.

        The level of evidence required increases with the audacity of the claim. That's because outrageous new physics is almost never the case, for the same reason that miracles or aliens are almost never (or just never) the explanation for something.

        "Extraordinary evidence" is usually interpreted, nowadays, as unobtainable evidence, with the effect that any discovery incompatible with current consensus is reflexively discounted. This is less often harmful in cases where the current consensus is based more on actual evidence than on groupthink and conformity. So, in physics, there is actual evidence for most things observable. But there are plenty of fields where fashion prevails. Without citing current problem children, geology until quite recently forbade mention of catastrophic events like bolide strikes, and psychology filtered all hypotheses through behaviorism.

        It's evidence so incontrovertible and ironcland that the chance it is wrong (or faked) is less than the chance the outrageous claim is true. This could be close to unobtainable, for sufficiently outrageous claims. The argument I am making goes all the way back to Hume's "Of Miracles". In the specific case of Cold Fusion and the like, the evidence is further impeached by the lack of progress. What's happening looks just like a pseudoscientific study of nothing that spits out bad results that never goes anywhere.
