Hotter Platinum at the right Temperature and Pressures
Last week we finally saw a clear signal of the Platinum wrapped thermocouple exceeding the temperature of the Silver wrapped thermocouple. This is what we were looking for as evidence that the Celani wire, with its nano-structured surface, is splitting Hydrogen and generating free monatomic hydrogen.
The signal finally became clear as we swept the pressure from a high of 50 psi to 6 psi.
Power: 46 W
The range where the Platinum is hotter appears to be between 20 psi and 52 psi. (1.37 Bar to 3.65 bar) We see it as we increased the pressure and as we decreased the temperature.
Wire temps from roughly 242 C to 368 C.
There appears to be strong interplay where T_wire drops rapidly with more H2 pressure above 17.5 psi (1.2 Bar)
The Pt being hotter than the Ag effect was not apparent in 90%Ar gas, even though the active wire operated much hotter.
(NOTE: The T_Cu thermocouple is actually clad in Ag wire instead of Copper wire for these experimental runs)
The temperature drop at 23:40 is a notable event that is not correlated to anything else, as far as we can tell.
The wire temp increases as the pressure drops up to a maximum of 374C when the pressure is at 13.6 PSI.
90% Ar / 10%H
Next we tried to get a higher Wire temperature by running in 90% Ar, 10%H. The shape of the temperatures gave was similar in many ways, but the Pt temperature never exceeded the Ag temperature.
50% Ar/ 50% H
We see a choppy region at 20:00 UTC. Note that the thermocouples do not cross each other but get close at 20:20 UTC. The pressure drop was not as smooth a curve as the others, but the qualitative shape of the temperatures compared to the pressure is similar. Still, we do not see the Pt ever exceed the Ag temperature. We do not know what caused the bumpiness about 20:00.
Since we now had a pressure range where the effect happened, we started exploring the range of temperatures where this effect happens at various pressures. The results are not entirely clear, so far.
Is there Monatomic Hydrogen, or is this a different effect?
This experiment was conceived to test the hypothesis that Celani's wire was splitting Hydrogen at temperatures below where it would be expected. The idea is that the Platinum (with electroplated platinum on it's surface) would preferentially recombine any monatomic hydrogen compared to the silver. Our data seems to support that. We must ask ourselves what other effects may cause a difference in temperature between platinum and silver in this test cell configuration.
Some possibilities include:
- strange convective effects - can't be ruled out completely
- localized radiant heat sources if the wire is not heating perfectly evenly - with the same wire in the same cell, untouched between runs, with only gas composition changing, we see notable differences in wire behavior.
- Some other thermal path changes based on thermal conductivity of gas from reasons other than H2 splitting?
