LED's Efficiency Exceeds 100%

New submitter Paul Fernhout writes "Physicists from MIT claim to have demonstrated that an LED can emit more optical power than the electrical power it consumes. Researchers suggest this LED acts like a heat pump somehow (abstract). Is it true that 230% efficient LEDs seem to violate first law of thermodynamics?"

    They must have used the wrong cable, causing the light to go faster than C and mess with their readings.

      I thought you had to reverse the tachyon polarity.

      Nothing can go faster than C. Except Fortran, of course.

    as most people think Light Emitting Diode when they hear LED.

    But in this experiment they are referring to a Large Entropic Dilemma.

    So the results make perfect sense.

    Read the article? Heck, I didn't finish the headline. As soon as I realized it didn't mention iPads I went straight to the comments to argue we should instead discuss iPads.

    Why don't we have iPad 4 speculation yet?

    So, you're saying that future computers, if we don't want to spring for fans or liquid cooling, will have to be lit up like a modder's case?

    I guess that's great if you like your server rooms to also double as sweet rave parties.

    Will LED become next generation of cooling appliance?

    "That's a bright idea, he said coldly."

    Also, heat-activated lighting. Also, if you can suck heat from the environment to make light, and then pump the light to solar cells to make electricity, you have a heat-to-electric converter.
