After trying the wire repair, we loaded the wire overnight at a few different temperature steps. The cell was heated by the NiCr wire. That means that for this phase of the experiment, T_mica is a pretty close measure of the actual temperature of the Celani Wire.
The Impedance went down to a low of 16.37 @ 202C from a starting (from this loading) of 18.23 for R/Ro of 0.898
When the wire was later cooled, it went down to a low of 15.68, for an R/Ro of 0.86.
The Ambient was steady within +/- .01C
The Excess energy rose slowly from and average of -.5 to 0. This could be attributable to the drop in Hydrogen pressure, but it is interesting to note that we are now in the range of performance we saw in the very first runs with the Celani wire.
Next Steps:
Try a run at 3.5 Bar of 75%Hydrogen, 25% Argon using both wires at the same power level we were at yesterday.
Comments
In a papre (ICCF17) Celani siad that yes indirect heating works, but that heat is not all, and direct current seems to make "excitation" more efficient at same temperature...
We should also remind the claims of Brillouin and Defkalion who clearly state that heat count, but some non thermal energy can help to trigger...
about the light idea, like I said before one technique to detect if it have an effect is to make it periodic or pseudo periodic, to capture correlation from the noise. system is non linear, but one can catch correlation even from uncertain corelation.
anyway to the team: keep going! making it work first is the key... after than can detect what make it work... make it more precise, more efficient, more variable, more reliable... after...
The increase after the drop has been very marginal however, if you check it in context. It can probably be safely regarded as constant:
I personally get the very slightly increasing behavior as a sign that active the wire can't load any more hydrogen in those conditions and it's behaving like a normal wire. Now, it would be interesting to see what happens by repeating the vacuum-loading cycle again with the same power setting. It appears Impedance_red is quickly hitting an asymptote.
I wonder if it's just really "shock" that it needs, or if by loading, cooling and vacuuming in reality you're also taking out impurities on the wire (oxygen?) which prevent deeper loading. If the latter is true, then it might be an idea trying to heat the wire under vacuum (you'd need to be very careful).
- Is the 250-300 watts run mentioned yesterday (before an anomaly appeared) still planned if no apparent excess heat will show?
- Have you considered a short run at 7 bar to see if the wire can be loaded a bit more?
- Have you read my suggestion in this thread? > quantumheat.org/.../... It would have been interesting to see if that actually had any effect while temperatures were stable.
EDIT: R/Ro in this run appears to have improved. In the very first runs too it was noted that cycling cooling->vacuum >loading appeared to improve R/Ro.This might be something worth to check out more in detail (also at the 7 bar I suggested?). Maybe there's an optimal number of cycles to maximize loading without wasting too much gas and too much time.
[however input power is also different from the previous run, so maybe they are not really comparable?]
In my estimate, it most likely does not matter which wire carries the current as long as the active one reaches an adequate temperature. The gas will be at a relatively higher temperature when the heat is only from the inactive wire and this might be a major factor for heat production.
This is a fine experiment that you guys are conducting, keep up the good work.
