I see what you refer to Jeff. And if you look at the behavior for the 15 watt power level just prior to that point you notice that the R/R0 is slowly rising at about the same rate. It suggests that it wants a power level of the average of these two or 22.5 watts to be flat! If we consider this for a moment, it weakly suggests that two temperature related processes would balance out at the temperature associated with 22.5 watts of joule heating. Do any interesting ideas appear within your thoughts?
A quick calculation from this chart suggests that 48 watts of power applied to the inactive wire causes roughly the same R/R0 ratio in the active wire as 15 watts of power directly applied. The problem that is demonstrated during the early time period of this chart makes me hesitant to assume this conclusion, but at the moment I do not have an alternative.

Nothing was said about doing any special processing on this wire. There's something else weird about the slide. The last bullet at bottom says "the R/R0, of both wires, just slightly increased (as expected), increasing the temperatures." But look out to the right at the red line. See where it takes the second jump from 15W to 30W? This will obviously increase the temperature of the processed wire. But look at the purple line above it. The resistance actually *drops* slightly over time while the power is held at 30W, which contradicts the last bullet item. This is labeled as a pure Argon test run, remember. No H2.

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
