This has been a day of interesting mini experiments.
First was trying to learn about the air currents around the cell. We used a neutral buoyancy smoke generator to examine how much air was moving past the cell and in what directions. There was no "AHA!" moment, but we generally have a better picture.
Next, right about noon, there was a decline in P_xs to the lowest levels we'd seen it, immediately followed by a permanent rise to higher level that it had been in days. The decline preceding it got to -6 watts. Paul joked that if it got any lower, maybe we could invent a new refrigerator, instead.
Then the power rose and we were excited instead of joking. We can not adequately explain why either event happened, but here are a few of the things that happened along with it. The Ambient started to rise when Malachi and I went in there to test the airflow around the cell. We were working around the cell and standing at the computer. It is possible we disturbed the cell air flow or the room temperature controls. Malachi and I left the lab at 12:30 and went to lunch. The rise after 13:00 can be attributed to a sunny warm day heating the main building that supplies warm air to the lab. The main building is designed for a certain amount of solar capture.
So the Ambient rose 0. 5 C. Why did all the cell temps rise significantly more than that?
The impedance did something funny, too. Any suggestions what that dip means?
And the pressure looked interesting, too, but I cannot exactly correlate it to anything.
And that kept us happily entertained for hours till the next interesting thing came along. We learned that our wire may be damaged. Acting on a tip from Celani, we just attempted a wire repair without removing it from the test cell. We vacuumed out the hydrogen, opened it to the atmosphere. Then we heated the wire to a red glow for 10 seconds and then killed the power and let it cool.
We will insert a video as soon as we can get it uploaded.
