As illogical as it may sound on first blush,
can any electrically powered thermal device (looking pretty much like a tube
furnace) function in such a way so as to convert a hot blackbody surface
into a cooler (but still quite hot) coherent infrared interior ... with
superradiant resonance at 15 THz?
To make it a little clearer where this suggestion is going -
imagine a stainless steel tube sealed at both ends, so as to operate simply
as a cavity resonator for unfocused infrared radiation (instead of operating
as a laser emission tube). Imagine it is a version of a gas-phase optically
pumped non-focused IR laser -- in which the gas is a hydride, perhaps KH,
operating at partial vacuum. Here is a predecessor design.

The optical pumping mechanism is supplied by hotter IR
radiation from a superabsorbent re-emitter, such as a silicon-carbide
exterior tube, with the inner stainless tube centered with minimal contact.
That silicon-carbide superabsorbent re-emitter tube is itself heated by a
resistence heater at over 800 C. It remains hotter at its peak temperature
than the interior tube at 447 C because the interior tube is
absorbing/re-emitting predominantly at 15 THz or 20 micron radiation.
Thus the net effect is that the inner superradiant tube
emits extremely intense radiation but with a lower peak. This is similar to
Randell Mills "emission-line broadening" but in IR.
These dynamics would result in a skewed emission curve for
the external tube as well. Emission line broadening allows massively more
net energy to be emitted from a source at a lower effective peak temperature
- compared to blackbody assumptions. Thus the HotCat could be even more
energetic than imagined, based on the technique used to measure it - which
assumed no line broadening
Possible, or no?
