Making Strides Toward Low-Cost LED Lighting
Roland Piquepaille writes "You all know that incandescent bulbs are pretty inefficient, converting only 10% of electricity into light — and 90% into heat. Light-emitting diodes, or LEDs, could soon replace incandescent and compact fluorescent bulbs in our homes. They are more efficient and environmentally friendly. But LED lights are currently too expensive because they are using a sapphire-based technology. Now, Purdue University researchers have found a way to build low-cost and bright LEDs for home lighting. According to the researchers, the LED lights now on the market cost about $100 while LED lights based on their new technology could be commercially available within a couple of years for a cost of about $5. It would also help to cut our electricity bill by about 10%."
With the cost of solar cells and LEDs plummeting, a solar cell roof installation with closed-circuit LEDs might soon become cheaper than a ceiling window.
What do you know! Soon enough it'll all get so efficient that with closed-circuit LEDs shining on solar cells you'll be able to make your own infinite source of energy!!
Oh shit that's a hell of good idea! The first one to the patent office wins!!
You just got troll'd!
They really have a phobia about LEDs there- especially if there are wires attached like an AC cord.
