>From the video, I gather Deneum is are trying to measure heat with a single thermocouple on the outside of the reactor. This is a bad idea. As I said in the paper, you should use a calorimeter. If they were to get ~100 W of excess heat I suppose they could detect it with a single thermocouple, but it seems unlikely to me they will get that much heat in the first attempt. I suppose that at best they will see 5 or 10 W, the same as Mizuno saw last year. You cannot detect that with a single thermocouple.
Someone told me they would be disappointed of their replication produced only 5 or 10 W. That makes no sense to me. Any certain level of excess heat, even 1 W, is as good as 3 kW from a scientific point of view. It proves the effect is real, and that Mizuno's larger results are real. You can work from that to recapitulate Mizuno's efforts over the last few years to gradually ramp up to 100 W, and then 3 kW. It will take you a year or so, I suppose, because this is fundamental research into a phenomenon that no one understands. Someone suggested that a "valid replication" would have to be 100 W. I said that would be a miracle, not a replication. People should have realistic goals, and they should use every necessary tool to achieve them, from a mass spectrometer to an air-flow (or Seebeck) calorimeter. Taking shortcuts and leaving out essential steps and instruments makes it unlikely you will succeed. As I said, perhaps you will succeed if this experiment turns out to be much easier and more forgiving than Mizuno and I think it is.
