Maxwells demon is alive! (Score 1)

This is a Light emitting diode operataing in the IR spectra, if it has properties that allows it to do sorting (=dioding) on thermal (IR) photones - we are on to something very intresting. Making the high energy photones go to one side and hence getting a cold side and a warm one? Airconditioning and heating without running up the electrical bill or burning fossile fuel... Next question is if this can run without the input of electricity? and if the ammounts of energy are intresting or just a novelty?
