So what are you saying? Is there a problem with a 0.1 mm gap, or is there
not? Are you asking me to waste my time doing a test that will not prove

I have never asked you to do this. It was your wish.
It is a simple problem for me. Tere are two heatt resisteances in series
and the heat resistance of a 0.1 mm air gap is much larger than the
resistance of a metal-metal connection. I know what happens when a
transistor is not firmly connected to the heatsink.
This all depends on the thermal flow. If there is no thermal flow, then
it has of course no effect.
If you have a good reason to believe there is a problem with measuring
temperature by putting a thermocouple on a pipe, please tell us what it is.
I have always said this is perfectly fine, if it is correctly done.
Do not make up reasons in the morning and then in the afternoon -- after I
offer to test your hypothesis -- suddenly withdraw your ideas.
I spent an hour and a half on this actually testing skeptical ideas. Okay,
that isn't much time, and the test was rudimentary, but that is still 1.5
hours more than all of the skeptics combined have spent. I showed that
trapped air is not a problem, and that cold metal next to hot metal cannot
produce a measurable effect, where the metal temperature difference is ~40
deg C.
If you want me to try something else that is fine, but please do not waste
my time with tests that you know will prove nothing.
You waste your time. You try to support Rossis crappy measurements.
Nobody asked you to do this.
If anybody needs a proof, then you need it, to support your businesses.
I have never asked you. Can you show a posting where I asked?
I know how to calculate multiple heat sources and multiple heat
resistances in combination.
Please see it: Rossi is unable to proof a COP of 6.
But he says he has a billion dollar invention.
Isnt this ridiculous?
