What kind of loading ratio can be achieved by loading palladium with deuterium gas at high temp? Sounds odd that loading stops reaction.

Avoiding too high temperatures seems to be working... Did about two weeks run without explosions.
btw, according to Elon Musk "first principles" should be used, but how to apply that to cold fusion? Or what are the fundamental principles of cold fusion?
-
Maybe should add one more car part: knock sensor or some piezo that could estimate max pressure if/when explosion happens
-
The explosions i saw sounded like hydrogen-oxygen explosion, and were not very powerful, but managed to kick the glass jar lid open and break some weak 3d printed parts. At least one was logged for current and temp once per second, basically there was nothing unusual and then temp dropped due to opened jar.
I read a physics book "Fundamental University Physics: Quantum and Statistical Physics Volume III" and that gave me the idea about thermionic emission. Still have not tried to actually calculate if that is relevant.
There is also stuff about hydrogen, recommend reading that before starting to talk about condensed state of hydrogen.
About filtering water vapor with paper: what prevents the paper from getting wet and then vapor leaks to the other side? Was that measured to work?

I could try to measure oxygen. Not sure about plasma flashback etc., how to detect? I'm not interested in things that cannot be measured
-
Current setup: There is K2CO3 water below, and anode is separated from cathode so that anode bubbles oxygen out of the system, and cathode bubbles H2 into reaction jar. Then I have hot wire (for example nickel) and I heat the wire with current after the jar is filled with hydrogen. I start by filling jar with water to make sure there is no oxygen.
One possibility for oxygen is some overpotential in cathode, is that possible?
Another possibility is electrolysis of water vapor, but that would require high voltage I guess.
Also thought about using car oxygen sensor (lambda sensor) to directly measure.
-
Yes but where does the oxygen come from? I have been separating oxygen and hydrogen, so there should be no oxygen in the reaction jar, but still sometimes explodes, and i think with high temp, like 700 C. There is also some ignition temperature limit for the mix, once it has been created.
Switching off makes sense if switch or wire gap is in contact with the gas, since typically switch off creates short high voltage spike due to inductance.

I have seen some explosions while doing cold fusion tests, and now I think the reason could be thermionic electron emission from the hot metal combined with some water vapor, that is coming from hydrogen electrolysis. So water -> oxygen -> explosion. Is this possible, i.e. how much energy is in the electrons emitted vs. H2O molecule splitting energy? If possible, what is the critical temperature for this to happen?
-
One possible error source is the pressure inside the tube. If pressure changes, thermal resistance changes and the formula does not give correct answer. But if nothing moves and pressure is the same, just measuring one point should be ok?
-
In parkhomov translated paper, there is curve power vs. temperature, and it has been fitted to polynomial with terms for temp difference and also for absolute temp for T^4. Compared to Stefan-Bolzmann law, there is rather big difference in the coefficient for T^4, is that error or what should the curve look like theoretically? (or actually the area of the object must be used to scale, then t^4 coeff makes more sense).
Tried decomposing the curves:

Looks like it is impossible to go over 4000 C in temperature, everything melts?

This version a few days, not during the night. For example i just let the cell go dry, got somewhat higher temp near anode (54C at 17V and 300 mA), but then current started dropping, is now 30 mA.
Seems that higher current makes anode oxidize faster, could be useful if lead or lead oxide is the active part.
-
Have been running the lead/activated coal version now, no "events" seen, but the anode region seemed to get slightly hot, and the reason seemed to be resistive heating, or most of the voltage drop was near anode. This was most clear when there was only a little water inside the carbon. After changing polarity voltage drop has been more even. Maybe there is conductive lead buildup near cathode?
-
https://www.google.com/patents/US20050233216 this patent describes lead alkaline battery, maybe rather similar to the cell?

Has BrLP measured x-ray/gamma/neutrons in the reactor?
Has BrLP measured the silver fuel for transmutations?
Has BrLP measured residual radiation after test?
