Over Unity LED Light a Reality

Posted on October 30, 2013 at 11:05am 0 Comments

MIT researchers have created an “over-unity” LED that absorbs ambient heat energy.

The LED produces 69 picowatts of light using 30 picowatts of power, giving it an efficiency of 230 percent. That means it operates above “unity efficiency” — putting it into a category normally occupied by perpetual motion machines.

However, while MIT’s diode puts out more than twice as much energy in photons as it’s fed in electrons, it doesn’t violate the…
