We started a run heated with both wire in 3.5 Bar of 75%H/25%Ar.
When we turned up the temp with both wires we saw the impedance drop first, then start to rise again. When we review Run 1 on Nov 12, we see that we were absorbing quite a bit at T_mica=156 and Current in the Celani wire = 1.7 Amps. So we decided to run both wires so that we were running 1.7 amps through the Celani wire, but heating with both wires. We will see what this does to the loading (if anything). Then we will turn off the NiCr wire and see if it continues to absorb at that current and a lower temperature. We also saw that the impedance during that run was way lower than we currently have. Maybe it has to continue to absorb more. Or maybe those parts of the wire that didn't turn black again are not changing impedance as much.
Anyway, when we stepped the power down, I noticed something in the shape of the impedance graph. It might lead us to be able to estimate the wire's operating temp. I propose that the wire drops in a second or two to the temperature inside the cell. The size of that drop might be used to calculate what temperature the wire was operating at.
The power drop:
The cell temperature drop:
So, I need help from all the wonderful commentators to figure out how to correlate this back. Any suggestions?

This however would show that if we are to measure excess heat in the order of a few watts (although as I mentioned previously, this isn't what was originally expected), then testing conditions must be kept as stable as possible, and the reactor has to be isolated as much as possible from external influences. The kind of calorimetry currently used is ok for large anomalies, but it's too fragile for small ones.
*By the way, I'm curious to know too if that camera flash thing has actually been attempted!
Could Celani's wire resistance mainly depend from chemical/morpho logical transformation?
The so called repairing treatment oxidizes the wire. The black color is typical of CuO (1), whose resistivity is much higher than metal. In Cu-Ni-Fe alloy, coppers can be found at higher concentration on the intergranular matrix and CuO formation has the lowest heat of formation among other oxides (2). Oxidation of the wire increases its resistivity.
During the so called loading phases, the H2 gas progressively reduces the CuO to metallic Cu and resistivity drops to the original value. The reaction rate increases with temperature, starting from about 200 °C (3).

Celani reported gamma bursts that lasted about an hour when the wire temp was about 100C. Have you had the chance to monitor it on this run?
Too early to call - but this might be an experiment to watch
Since your last voltage change, pressure dropped by 1 bar and T_Mica increased by 3`C. I know its not much to conclude anything, but the vessel can be filled up to 4.5 bars after say 24 hrs and if the T_Mica still keeps rising, we have something.
Anyway, I would say let it run till P_Xs touches +2W approx. Then you can play with pressure if needed at all.
P_in has actually gone down a bit due to rising impedance, still the temperature is rising, thats amazing.
What I think is happening currently is that both sensors are increasing in reading and trying to reach each other as internal gas pressure decreases and convection is decreasing. The rest (external glass very slightly heating as well) might be due to the system slowly trying to reach thermal equilibrium.
ATM there's nothing yet suggesting me that LENR is occurring; current cell behavior doesn't look that interesting either. Keep in mind that unambiguous signals were originally expected, so calling a potential couple of watts of apparent (calculated) excess heat a success it's too premature at this stage.
@Ryan Hunt: this might be the right time to try "stimulating" the cell with the camera flash suggestion I proposed last time. That increase in P_xs was quite anomalous. Have you already tried? I know it sounds like a dumb idea, but...
From the trendline of P_Xs, it should go above 0 in next 12 hours.
T_GlassOut is also clearly increasing.
I had a side-thought about an easy treatment for the wire - rub the wire down with ferric chloride? I've seen some papers about the synthesis of nickel nanoparticles using FeCl3 - so maybe this could cause nanofracturing of the wire?
T_Mica has risen by 1.5`C, while T_Amb and P_in are constant and for the first time P_xs is showing a continuous upward trend, not random.
Impedance is not dropping, so its not the usual loading phase. Note that in Celani's graph the impedance was also rising during excess energy phase.
Only thing that dropped is pressure, so the temperature increase can be due to pressure drop (less conduction). But I think you are near the sweet spot at this time. (hopefully)
Is there any calibration curve for T_Mica/pressure , so we can see how much pressure drop causes how much increase in T_Mica ? If the increase is greater than calibrated value, then you have excess heat.
Why not ask Celani for an already tested (i.e. excess heat in Celani lab) wire ?
In turn, you may send your probably damaged wire to Celani and he could verify if it works or not.
This should tell if the problem is in the wire or in the measurement set up (of your reactor or the one of Celani)
Is it feasible?
Thanks and keep on!!

Two questions:
- Does daylight have access to the room, I guess not?
- How quickly was vacuuming/press ure reduction done, in comparison to Celani? If pressure is reduced too fast, maybe hydrogen outgasses violently, perhaps it kills the wire.
Not that we are aware of - straight from manufacture
Did Celani tested the wire before send it to you?
Thanks
Ric
