I disagree with your "basic idea of entropy."  If one could make a space
heater that produced 100% of its energy in a small infrared band, the
production of entropy would still be large.  Entropy is an indicator of
the irreversibility of a process -- it says nothing about a "frequency
band" of energy output.

Does anyone disagree with me?
