Its a complex situation isnt it? ... but fundamentally quite basicThanks for linking to the video again kiwi.
I really had to watch it again after a few years.
He does actually cover that in his papers, and points out the application via Plancks equation is actually valid but only so in the case of a PERFECT situation, which even in the case of Graphite shows its a theoretical "perfection" and in nature the situation does not exist to that degree of absolute perfection.There is also the matter of the "perfect black body radiation", which Robataille does not go into much.
All you need to ask anyone who claims this line of research is false is "do you own a cell-phone"? .... If all cavities contained Black Radiation as claimed by accepted Science then Cell Phones ( and UHFMRI scanners for that matter) would not work. Its a devestating "truth" that leaves no wriggle-room for weasel wording deniers
..... SNIP......This reality is well-known in microwave technology and
is the basis for the existence of resonant cavities. Conversely,
if Kirchhoff was correct, then any radiation incident into a microwave
cavity would become thermalized and immediately
change the temperature of the cavity. Signal would be lost as
the radiation became blackbody at the final temperature of the
cavity. However, the reality is that microwave cavities used in
electron spin resonance and much of telecommunications are
resonant devices. They are made of nearly perfect reflectors
over the frequency range of interest. The same situation is encountered
in Ultra High Field Magnetic Resonance Imaging
(UHFMRI) wherein resonant cavities are utilized to acquire
images [10, 11]. The use of such cavities clearly demonstrate
that Kirchhoff’s Law cannot be valid, as MRI depends on the
conversion of signal from the spins into voltage, without the
loss associated if the cavity was acting as a blackbody. MRI
uses the ability to build up standing waves in resonant cavities
during testing, transmission, and reception, in a manner
independent of cavity temperature [10, 11].
The arguments advanced relative to resonant cavities in
the microwave and at MRI frequencies is not solely geometrical.
Absorption of incident photons, transformation into thermal
vibrations, and re-emission into thermal photons does not
occur in perfectly reflecting cavities. Kirchhoff and Planck
cannot claim otherwise, when they assert that all cavities contain
black radiation [2, 3, 8].

Cheers Paul .... If you have not already seen these videos released by Dr Robataille I highly recommend you do... designed to educate the likes of us lesser educated peepsThank you Kiwi.
That helped.
