    230% Efficient LEDs

    "The extra energy came instead from lattice vibrations."

    This is not a violation because the lamp is operating in an energy sink where the background temperature is well above absolute zero. To me this is exciting because it shows that a device can be built to extract energy from the background state of the sink and however you want to look you are ahead of the game. There is still a lot to learn about basic physics which we have just begun to experience.

    What if instead of an LED it was a laser diode with a similar semiconductor bandgap and this laser diode with x>100% efficiency was a diode pumping another similar optically pumped laser diode with x>100%? Total efficiency is the product of the efficiencies of all the components so adding an x>100% pump diode would make it slightly more efficient than a few picowatts. Or as I call it "Nano-Death Ray" :-)

    You see what is wrong here? Always trying to make weapons and not trying to improve man's lot in life, HA!

    Holovision: won't discuss if it's a possible design but what you propose would be too expensive to manufacture and sell. Ed
