Arnaud,
I was complaining about the lack of calibration, but realize it is too late for this particular wire set. It just seemed logical to me that they would have immediately completed a re calibration after seeing the bad data from the first pass. We agree that the wire temperature is likely the most important factor, but I hold the thought that the dissociation of the molecular hydrogen is possibly bound with the gas temperature. The energy required to break the bond must come from somewhere. Take a look at Celani's charts for deuterium loading and you see that the process was endothermic for a period of time before it became exothermic. This behavior makes sense if you consider that the energy comes from the gas to accomplish the requirement. Do you have a technique to calculate the gas temperature in the vicinity of the LENR wire surface? I suspect that the temperature difference must be adequate to allow convection and radiation to extract the joule heating. Celani touches upon the idea toward the end of his paper where he hints that the LENR wire may be 350 C- 400 C (page 36) while the gas is less than 200 C. This is a significant difference. I had another interesting thought about the material he chose for the LENR active wire. Perhaps the large catalytic power regarding hydrogen dissociation (page 11) is another coded word for better LENR candidate. We have seen that LENR activity is related to the rate of proton loading into the metals and releases energy for each reaction. And it takes significant energy to break the hydrogen bonds which must come from somewhere. So one might ask if the LENR released energy tends to make the original catalytic power appear larger. If true, then a path is revealed to locate the best candidate metals.

The Number #1 which has been destroyed (at least cut) ? Celani doesn't need a new calibration to go further in its investigations. Only for reporting the re calbration is useful. In my point of view, the temperature of the active wire is more important than the gas temperature. At the vicinaty of the wire, the gas will be close to the wire temperature. So it doesn't suprise me that Celani has better excess power while heating the active wire. The measurements of wire's temperature are very difficult to perform with simple thermocouples or thermistors. Celani should try to measure the wires with an IR camera. This will show how yhe temparture of the active wire is relevant regarding excess power generated. You are right about the decoding of Celani's report which contains a lot of underline informations.

But why did he not do another re calibration with the changed wire so that it made sense? All the remainder of the tests were conducted with the 48 watt drive power level so he could have given us a good reference. I also was wondering if the test just prior with normal air allowed oxygen to bind with the material and change the readings. It is not evident at this point that I will be able to reconstruct an accurate coupling value to use later. I was looking for the equivalent watts released within the LENR wire when a know value of watts was applied to the heating wire. This concept sounds strange but let me explain what I refer to. First of all, heating due to current within the LENR wire will cause its temperature to rise by a certain amount. The relatively good thermal conductivity of the wire will tend to keep the temperature within the wire uniform since all the heat lost from it exits into a much less thermally conductive active gas. Furthermore, there will be a significant temperature drop at the interface between the LENR wire and the gas which causes the heat to be removed. The other process, where the heating is due to current within the inactive wire, should result in the LENR wire being close in temperature to the gas within the mechanism since no heat flows between the gas and the LENR wire once equilibrium is established. Does it take 10 watts of joule heating inside the LENR wire to reach the same wire operating temperature as when 48 watts is supplied by the inactive one? Of course the gas temperature will be far less with the 10 watts applied to the LENR wire, but the question remains as to whether or not the temperature of the LENR wire is more important than the temperature of the hydrogen gas. My thoughts are that both are important but the wire temperature dominates. Another very important piece of the puzzle is the amount of excess power generated by the device which appears to be in the vicinity of 10 watts when heat is coming from the inactive wire. If the active wire only needs 10 watts of joule heating to reach the same operating temperature, then the suggestion is that we are very close to seeing a COP of 2 which can relatively easily be coaxed into a positive feedback condition. My first pass observation of the excess power plots within the report suggests positive feedback action. Notice the shape of the noise spikes and the fact that they are large. This is a characteristic of a system that has many small regions that undergo positive feedback until each is quenched by some process. I would like to prove this hypothesis. I suggest that we apply a significant amount of effort to decoding Celani's fine report since a great deal of knowledge appears to be coded within the data.

After cooling, the inactive wire resistance drop of approximately 0.03 from the before calibration situation. That's why Celani didn't try the 48W on its active wire.

Has anyone discovered an explanation for this discrepancy? Dave
