He says that failing to recreate Fleischmann and Pons&#x27; findings isn&#x27;t enough reason to doubt their claims because recreating results is tricky, and implies that therefore we have no actual reason to doubt that they achieved cold fusion. But we do.<p>Not only did their apparatus, according to their own measurements, not produce any of the radiation that would be an unavoidable byproduct of fusion, but the core also didn&#x27;t contain any fusion byproducts. As a result I think it&#x27;s perfectly reasonable to conclude that they could not possibly, in any if their experiments, have achieved Fusion. If their measurements of excess heat are true, whatever it&#x27;s source was, it wasn&#x27;t fusion.
