There are hints of success in the mountain of data being collected. There are also plenty of valid criticisms of the experiment to date. I will try to summarize them here. First, we will look at the graphs from each cell. Then we'll look at the arguments about the interpretation. And finally, we'll talk about the plan to clarify it.
Graphs - 15 minute averages for the last two weeks (since the last power adjustment)
The T_Glassout sensor does not show an up trend. In fact, it shows a drop off.
If we zoom in after the adjustment we see the weekend rise.
And now the extra sensors for cell 1.1
T_F2 is on the top flange. T_G1, T_G2, and T_G3 are glass temperatures. Almost all of these sensors show an initial event between the 28th and 30th and then quite a bit of noise before an uptrend this weekend.
Serious criticisms against this being real excess heat:
Honestly, all the great input has been like drinking from a fire hose. Forgive me if I miss anybody's contribution. If I do miss your idea, please re-suggest it.
- Small (if any) change to T_Glass out - As is pretty obvious, the T_glass_out sensor is not showing the same rise in temperature that the internal temperatures are on cell 1.0. On cell 1.1, we had to troubleshoot the sensor a bit.
- Ascoli65's pressure compensation - Ascoli has made a pressure compensation formula that seems to level out the P_xs line nicely. Because of the lack of change in excess glass temperature to correspond to the interior temperature, this is a very plausible explanation and a nice piece of work. I would like to see somebody fit that pressure difference to a thermal conductivity value, but I'm not sure what to do about the convection part.
- David Roberson's heat up curve fit - While we have not had any power steps to fit his model to, lately, judging from the last one and the final temperature, he was not seeing excess power. Of course, he was using the exterior temperature and it is clear that it is not rising much.
Arguments for real excess heat:
Evidence of sustained temperature rises on almost all sensors on cell 1.1 - There was a bump of temperatures right after we upped the power between Jan 28th and Jan 30th. Then there was a gentle temperature rise this last weekend. Can anybody spot a reason those might not be excess energy?
Offsets of T_Glassout thermocouples - we have some doubts about the reliability of the thermal contact of those sensors. We had to trouble shoot it last week on cell 1.1. On cell 1.0 it just a piece of kapton tape holding it in place. On that cell, as soon as we put the active wire in and reattached the sensor, that sensor started reporting almost 10C cooler at full power. We decided to go ahead with the test, anyway, since we couldn't figure out why it had acquired that offset and we were using the interior sensors for the power calculation.
Thank you Alan G for sharing the graph of that data. They are extremely close and at this power level, the calibration was done at .91 bar, which we crossed not too long ago and definitely after the internal temperatures started to rise.
These calibration results are what lead us to decide to use the interior temperatures for the P_xs calculation. It looked to be a cleaner correlation and to not vary much at all over the desired working pressure range.
How does Ascoli's pressure compensation fit here? My personal hypothesis is that it may be fitting the change in gas composition over time, instead of the change in Hydrogen density.
I suspect that the gas composition changing. We suspect the H2 is leaking out. Are O2 and N2 leaking in and decreasing thermal conductivity? Would the air leak into the cell based on partial pressure even if the pressure of hydrogen was higher? Would that be a risk with any long term test, especially if the cell had a known leak?
- Cool down and restart - does it come back, or not? What pressure does it come back to? How does it fit David Roberson's curve predictor?
- Refresh the H2 - Cool down, vacuum clean, and reload to 0.5 bar clean Hydrogen.
-What other suggestions are there before we do it tomorrow?

And a bonus observation:
This graph shows some of the strange and dynamic things that this system does from time to time. This is fresh off the server. What do you make of it?
