Organic LED Could Replace Light Bulbs?
egrinake writes to mention a BBC article about a 'natural' replacement for lightbulbs. From the article: "The organic light-emitting diode (OLED) emits a brilliant white light when attached to an electricity supply. The material, described in the journal Nature, can be printed in wafer thin sheets that could transform walls, ceilings or even furniture into lights. The OLEDs do not heat up like today's light bulbs and so are far more energy efficient and should last longer."
Is there such a thing as 100% efficiency in any physical system in existence? Not that I know of. Sure they could get really close to 100% and that would be nice, but it wouldn't be 100%.
Yeah. And we will have change all light bulb jokes now. Damm.
