Alain, here are a few comments that might be useful.

I've got an answer with claim of artifact... probably an old story.
I imagine that to fool Ed you need more tha recombination ...
can you comment, and check I did not answer stupidly

@Alain Coetmeur The uncooperative Pons-Fleischmann exotherm requires
Li-based electrolyte, high current density, thick Pd rods. Li is
only slowly reactive in water. Pd dissolves Li. As with Hg
dissolving Na, Pd dissolving Li is a hugely exothermic Lewis acid-
base neutralization. Pd-Li alloys have deep melting point
depressions vs. Pd 1552°C mp: 145°C mp for 12 atom-% Pd, 950°C mp
for 75 atomic-% Pd, J. Less-Common Met. 55(1), 67 (1977).
This description is not accurate. Li is not required in the
electrolyte, the Pd can be any shape from wires to foils, and the Li
reacts only very slowly with the surface and diffuses over a distance
of a few tens of microns from the surface.
(0) Catalyst in the condenser recombines electrolytic D_2 and O_2 to
D_2O. It occasionally explodes when granules shift to expose fresh
surface. This does not count.
The recombination catalyst seldom explodes.
(1) Li metal electroplates onto the Pd cathode. Most reacts with
heavy water. Some dissolves in the rod's surface, creating a
lowering melting point Pd-Li alloy rind.
(2) Very high current densities have the rind eventually liquefy vs.
Li reaction with water and diffusion inward.
The surface does not liquify. A few local melted regions are
occasionally seen, but these are few and widely separated.
Sudden reaction with bulk rod is the Pons-Fleischmann exotherm
having no neutron, tritium (net 4.03 MeV), or He-3 (net 3.27 MeV)
production.
No neutrons are detected, tritium is occasionally made, and helium-4
production appears to be the source of energy.
(3) About 24 nanograms of D + D fusion is one gram of TNT
detonation. How big is the Pons-Fleischmann boom?
The total energy is being compared to the rate of energy production,
which is not correct. The rate of energy production from TNT is huge.
The rate from F-P is small even though the same amount of energy is
released. Consequently, the Pons-Fleischmann cell does not explode.

1 gram TNT detonated = 4184 J (one dietary Calorie)
D + D = 3.65 MeV average, 5.848×10^(-13) joules
0.5 mole D + D, 2.0141 g total = 1.76×10^11 Joules
1 gram TNT detonated = 23.8 nanograms D + D fusion

Interesting article on Science evolution...
It resonate with many things (out of LENR) I've noticed recently...
Mostly Science is dying of conformism... consensus...
It always have bee conformist, killing dissenters, but today this
conformism is getting industrialized, administered, funded, ,
globalized, mediatized, with method and rationality.

the comments are interesting...
the most funny is that answer:
"Phillip Helbig said...
"But if it wouldn't work, what all these publications are about?"
One can study theology at university, but I don't see this as a
proof of God's existence.
There is no confirmation of the Pons and Fleischmann result
published in a serious journal.
Even if your conspiracy theory is true and the establishment
boycotts cold fusion, why not just set up a power company and sell
the energy? Because it doesn't work.
