As far as I know, you cannot make a glow discharge appear with 10s or hundreds of watts. The calorimetry was challenging in the glow discharge experiments done by Ohmori and Mizuno, because both the input and the anomalous power fluctuate violently. The only method that worked was a variation of bomb calorimetry, that works for about 20 minutes. That is also about how long it took for the cathode to self-destruct, so the experiment had to stop anyway. > 2/ Also appears that they suggest only running the reaction for 90-240 > seconds and at temperatures of 93°C . . . > The temperature of the plasma (glow) is in the thousands of degrees. It erodes tungsten. That is, it makes dust out of it.

Everything in the cell is chemically inert; i.e., metal and water. Later there is free oxygen and hydrogen, but obviously the energy in that all comes from electrolysis and pyrolysis, so the net energy gain is zero. > 3/ Tungsten powder is active LENR matrix, about 2-5 grams (though not very > clear in the translation, it might be light bulb filaments). > Definitely powder.

It includes free hydrogen and oxygen from electrolysis and also from pyrolysis. A substantial fraction of the anomalous heat goes into pyrolysis. I recommend venting the gas or deliberately igniting it with a spark, rather than a recombiner. The limiting factor of duration in Mizuno's version of the experiment is the lifetime of the tungsten, which is about 20 minutes, as I said. > This is the sort of experiment that most chemistry labs could probably > replicate with very little cost in a few days, and I imagine many will try. > It took Mizuno months of practice to make this work. He went through hundreds of cathodes. Even after that it was difficult for him. Perhaps this new technique is easier. I hope so. As I noted, Mizuno's experiment exploded violently, producing far more energy than can be explained from the input power. All of the gas before the explosion was vented, so there was no chemical fuel available. The experiment came close to seriously injuring Mizuno, driving a large piece of glass into his neck next to the carotid artery. There was another person present. Both Mizuno and this person were deafened by the sound for several hours. The University ordered him to stop doing the experiment after that. He never did it again.
