True but to get the best of it you have to have high grade energy to
radiate. (High temperatures, short wavelengths). If you could
efficiently convert low grade warmth in large amounts, to a small source
of incandescent light, you'd improve it. I'm not sure if such a process
is easy or practical. To be worth doing, it would have to cost less
energy to convert than the difference in that emitted for the two
temperatures. It would probably have to use storage too, for long slow
inputs, short strong bursts of output, which complicates things.


Never mind what I wrote just now. Can't beat entropy.

No, but you *can* use a heat pump to move it somewhere else.
