    100 is 96 more than you need, I think. 2 on inlet, and 2 on outlet is sufficient. Check them against alcohol thermometers.
  • A huge thank you to Alan Goldwater magicsound for SEM and EDX analysis of my prepared mesh samples. As suspected, very little Pd was deposited. Alan's conclusions were:

    An appropriate date.

    A British friend of mine was married on April 2 because she said she didn't want to married on April Fools Day. Decades later she said: "if I had known what I was in for, I would have said April 1 is entirely…

    Suppose the device does somehow extract heat from the environment. If it produces more than a few watts, it should be quite cold. As cold as a small propane tank becomes as it heats a barbecue, from Boyle's law. It should be covered with frost. If it…

    And so, perhaps lost in the up and downs (above) is that when the calorimeter inlet TC is working normally, the open resistor, at 450+ C, glowing dull red wires inside the box has the same delta T as the 20 x 50 cm SS cylinder with the resistor sealed…

    I believe the spreadsheets we uploaded will allow you to do this. In any case, you need only three numbers: the input power and the inlet and outlet temperatures. I did the calculation for two or three of the low power…

    No. Sorry, I have been out of the office except briefly, and I forgot.

    No, I am pretty sure he did not. I have never seen an experiment with a rod of this shape and size. It is way too big, and Mizuno has not done…

    No, the Patent Office does not deal in theories. It only accepts engineering proof that the invention works. Nor is it supposed to reject a claim because that claim violates theory except in the case of perpetual motion machines.

    Yes. You noticed the problem almost immediately, and so would anyone else who compares the inlet to ambient temperature. It is impossible to miss. You might say, "but suppose we don't compare the inlet to ambient?" I think that…

    The inlet TC must equal the ambient temperature. If it does not, something is wrong. You should always monitor both.

    This problem would never cause a mistake, because you would always see that the inlet…

    The heat capacity of air hardly changes at the extremes of humidity. The humidity in a closed room in Sapporo does not change measurably from day to day. This experiment is not being conducted in a jungle.

    Such things cannot…

    Nope. Because these are Bona Fide actual authorities. Fleischmann and Bockris wrote the book on 20th century electrochemistry. It would only be an appeal to authority if they were not authorities. Which is why the fallacy is…

    You cannot reverse calculations! You cannot go from a computed value to modifying the parameters used to compute it. Calorimeters measure heat. They do not measure changes in air flow or thermocouple malfunctions. We know they do…

    When two separate instruments based on different physical principles (heated wire and vane) both show the flow rate is 2.3 m/s, they both agree, and they are both rated and certified to something like 5% accuracy, then the flow…

    The "COP" (output to input ratio) of today's LENR experiments is meaningless. It can easily be changed. The ratio has no scientific meaning, and no technological significance. This is not a "gain" in the technical sense. That word…

    That is not how calorimetry works. You are doing it backward. You know that the air velocity is stable, because multiple instruments confirm that, in multiple ways. You know the Delta T is changing because that is confirmed with…

    I do not know what you mean by this. His data leads to no such thing. He measured the air flow rate carefully and repeatedly with two anemometers, a hot wire type and a vane type, and he found significant variations. He did…
