The D2 artifact issue is not addressed. it is stated as fact that this is not a problem without evidence or rationale.
Everyone knows that the mass spectrometer must have sufficient resolution to separate these two. Every researcher addresses this. If this particular paper does not, you can be sure others from these authors do. As Ed points out, you are saying that experts do not know the fundamentals, and they make mistakes that only an undergraduate would make.
You here are criticising me with a straw man argument. I never said this paper claimed that. rather, when i look at all of the LENR eviudence, I look for coherence, or lack of coherence. I am stating that the tritium results are muhc too low to explain excess heat - which matters because if they were comparable then these two apparently different (unless we have LENR) observations would be coherent.
Coherence is a matter of your opinion, based on your ideas about theory. Cold fusion cannot yet be explained by theory. It is an experimental claim. The tritium is real. That is an experimentally proven fact. You have found no reason to doubt the tritium, or for that matter the heat, or helium. A reason can only be an error in the experimental technique or the instruments. The fact that you find it incoherent is not a valid reason to dismiss experimentally proven facts. Your personal ideas about theory do not overrule instrument readings.
The tritium does not have to "explain" anything. It exists. That is an irrefutable fact. You can confirm it in this paper, or in dozens of other papers. Tritium can only be the product of a nuclear reaction. Therefore, cold fusion is a nuclear reaction.
What you, or I, or anyone says about theory or coherence can never be a reason to reject replicated, high sigma experimental results. That is fundamental to the scientific method.
