Lets consider photovoltaic cells. Even at room temperature in complete
darkness (no solar) there are visible light photons striking the cell.
I calculate a 10 cm x 10 cm common solar cell would generate roughly
1E-30 volts. Not much voltage, lol, but still something nonetheless.
Well Paul, you might find that you can accentuate that small effect by
many orders of magnitude if you can get hold of a large parabolic
mirror. These can be specialty coated for IR.
Once again, it defies common sense, but such a mirror will focus and
amplify ambient IR photons. Even in darkness. Although this is very
inefficient, due to the long wavelength of this spectrum - it does
happen and in IR astronomy, for instance, they can get many orders of
magnitude amplification.
Get hold-of an IR spectrum photonic cell and also an IR (coated)
parabolic mirror and you can make you own demo of this - and make it a
little more meaningful than ^-30 ... geeze - you need to get it up to
where an affordable voltmeter will show something.
