    From the R19 paper: ”As the reactant temperature rises, the amount of deuterium in the reactant decreases. This causes the exothermic reaction to decrease and the reactant temperature to fall. When the temperature decreases, more deuterium enters the…

    I don't like to pick on details but it is part of a scientific process, as this discussion is, or should be. I hope my main objections will prove unfounded and that Mizuno's efforts will become rewarded, but the more I have looked into the data, the…

    Yes, that what I was asking for.

    Where, more precisely, is the thermocouple mounted on the reactor (axial and angular position)?

    It would be good to have details of the in situ heater geometry. It is a key component in any replication experiments. The distance between the windings (or whatever it is) and the mesh and the length of the folded heater are of particular interest. I am…

    Good idea, but it requires that the reaction continues long enough after turning off the heater. The heat capacity in the steel tube could also make the results less convincing if we haven't a self-sustaining reaction, as in this…

    It seems you missed a digit.

    Are there any calorimetry runs made with R20 producing substantially more than 300 W?

    If so, I can't see any logical explanation for why a thin insulation around the reactor would not provide high enough reactor wall temperature, equal to or higher than for a free standing unit. If you have a layer with high heat…

    Is it correct, according to you, that there is another parameter than the reactor wall temperature that is important when water cooling hampers the reaction?

    No doubt there can be a number of replication trials being made, but there are a number of ways to mess up the experiments, even for a skilled experimenter. Making the reactor work is just part of it. The calorimetry is essential. The calorimetric data…

    You assume that what I suggest is to convince myself. That is a mistake. It is all about convincing others. Those 180 replications did not pave the way for LENR, did they?

    Now, what we have is a very (in comparision) simple…

    Extraordinary claims require extraordinary proofs. In this case, I would use what otherwise would be overkill: two independent cooling and measurement systems, the first cooling the reactor using air, the second cooling the air using water. Keeping…

    The results are indeed impressive. The relative simplicity of the as-it-seems robust experimental procedure is encouraging. Difficult to find any flaws explaining the high COP. Mizuno has been in the game for a long time, many hours and good thoughts…
