I see, yes. I was thinking more along the lines of radiating heat energy at a scale that's useable for cooling, not at the more extreme levels of over 500°C/1k fahrenheit

That's technically correct I guess, at some temperature threshold it becomes possible to bleed some fractions of energy while the material is exceedingly hot.

Yeah, my comment was intended to be mildly sarcastic in that the proposed heat transmission mechanism already happens on Earth and is yet so dramatically insignificant at usual temperatures that we struggle all the time with managing heat transfer through other means.
