Some thoughts relative to the MFMP test.
I would be nice to know how the magnetic and optical properties, including
transmittance and absorption spectra, of the alumina with likely additives (for
example Li and Ni nano powders and hydrogen) change as a function of:
1. Temperature up
Jones, even though the accuracy of the temperature measurement is somewhat
questionable there are other indications that support the conclusion that
excess heat is being generated by a nuclear process.
You are forgetting about the fuel element changes that were measured. This is
a non trivial

That's awfully good of them! It is great to see such
I though that MFMP was buying that camera. Maybe its just good customer
service.

The original plan was to buy an Optris camera and sell it after MFMP's
experiments were completed. Bob Greenyer even tried to buy THE camera used
for the Lugano experiment. Turns out the Lugano camera was busy being used
in another experiment. Bob worked with the manufacturer to get a camera,
BTW – does anyone know the model # of the Optris camera used in Lugano ?

The reason for asking is that the model mentioned in the paper is the PI 160.
This camera’s standard version has a temperature range from -20°C up to 900°C.
It can be “optionally” expanded to 1500°C … for significantly higher cost.
… but do we know for sure that the Lugano camera was
I believe this is the same model the MFMP intends to get. The expansion
is the calibration at the factory for that high temperature range. That is
what MFMP is waiting for - there is a long queue for the calibration at the
factory. MFMP will be having the camera they borrow calibrated
There has been a lot of discussion about these photos published by the MFMP
on Facebook:

Look at the lower two photos. They look bright white. However, someone from
the MFPM commented at Facebook that they do not
The color of the MFMP dogbone and the Lugano hotCat are more complicated
than what you would expect from blackbody radiation. Both devices had
internal heaters at higher temperature than the surface of the ribbed
ceramic convection tube. At visible wavelengths alumina transmits a good

How about the color as perceived by the human eye? Is that of any value in

Because of the porosity of the alumina, the ceramic is a reddening (low

be reddened as it is transmitted. . . .

The eye does a good job at dealing with the infrared. Not everyone's eye
is the same, but someone that can see more infrared has been seeing it all
of his life and it is integrated into how he perceive color.
The real problem is that the color is itself not a good indicator of
temperature. Look
The far infrared behavior is expected to be much different than the visible
case. The Optris images at ~20 longer wavelength - 6 to 13 microns. In
this range, alumina is believed to be nearly completely opaque. The
emissivity will be different, but the fact that it is opaque is, by far,

surface.
Bob, wait a second … just today - in an earlier post you said (correctly)

From the experiments we have conducted, if a 1 micron wavelength Williamson
pyrometer had been used, I would say the whole measurement would be wrong.
However, at the 6-13 micron wavelength of the Optris, I am leaning toward
the average temperature having been measured correctly by the Optris. I

Well, yeah … the “unexpected sensitivity” is almost a given – at
