Photonic Structure Increases Light Bulb Efficiency

An Anonymous Coward writes "A new experimental microscopic tungsten lattice can increase the efficiency of an incandescent electric bulb from 5 percent to greater than 60 percent. This is done by converting waste heat into visible light. "

    IR seems to be the first thing people get when they're working with things that produce light. I believe IR LEDs were the first LEDs, and IR lasers were the first light emitting lasers.

    Second, I love this. They don't even have a THEORY on why this works. It just does.

    Third, If they get it working in the visible light spectrum, they'll have a bulb that's SIXTEEN time more powerful than tungsten bulb.

    That's one hell of a flashlight. I'll call mine "Little Boy". I promise to only use it in self defense. And to start small fires.

    Q: How many programmers does it take to change a broken light bulb?
    A: None, it's a hardware problem.

    How else do you improve the efficiancy of something!

    Where I work the beatings usually continue until the morale and efficiency improve.

    It works by "converting waste heat into visible light?" This is going to ruin all of those Easy Bake Ovens.

    And what about when my daughter finds a birds nest that has fallen out of a tree and we need to fabricate a incubator out of a box and a 25 watt light bulb to keep it warm?

    This is horrible news. Think of the children. Call your congressman and ban this insanity.
