Physicists hellbent on destroying the universe have come up with a tiny LED that produces 69 picowatts of light while using just 30 picowatts of power. That's an efficiency of above 100%, which should be impossible, but isn't. And in other breaking news, up is down, black is white, and zebras look the same.
So, how does this not totally and completely invalidate the conservation of energy? We have to look at how energy flows through the entire system, not just at the electricity in and light out. When the LED gets more than 100% electrically efficient, it starts to cool itself down, which is another way of saying that it's stealing energy (in the form of heat) from its environment and converting that heat into those over-unity photons.
This cooling effect has some interesting implications for low-power electronics, but most importantly, we can all rest just a little bit easier knowing that the basic physical rules that frame our perception of the universe have survived for one more day.
