Physics-defying LEDs light the way to a brighter cleantech futureA light-emitting diode (LED) developed at MIT operates at 230-percent efficiency. That’s not a typo. LEDs will provide 70 percent of the world’s general lighting by 2020. That’s not a typo, either. The cleantech revolution has barely begun.
