At one point the Nature paper is very positive, since it shows that there is no fusion reaction, i.e Cold fusion reaction producing heat is not detected.
So the research should go in the direction of fission (induced fission of stable elements), and this is good. I am still wondering why it is so difficult to except that there is no Cold fusion reaction producing heat ?
The opposite of fusion is fission, and nothing more, if you follow the logic - Law of excluded middle.
So, even heat excess in FP electrolysis had the possible explanation of Lithium fission as result of interaction of Lithium nuclei with hydrogen nuclei (protons).
The same fission reaction was even more clear considered as explanation of heat production in Rossi experiments.
Besides Lithium similar fission reaction can take place for Boron nuclei colliding with protons.
And it is also clear that you have to not only supply Lithium (Boron) and Hydrogen, but also stimulate the collision of them. And, the obvious way is to apply electric pulses.
