Ultra-Efficient Microwave Headlights Almost Here


Today’s cars get more technology jammed into them every day. With navigation systems, Bluetooth, DVD entertainment systems and other gadgets sucking juice out of cars, companies are looking at other ways to reduce electric consumption.

One such U.K. company, called Ceravision, has created a new type of headlight that it says is even more efficient than LEDs. The technology uses radio frequencies set at the same range as microwave ovens, and bulbs made out of quartz or ceramic materials instead of traditional electrode lamps.

If they really can be produced for less money than traditional lamps, and use less electricity, as the company claims, we have no doubt they will become widely adopted by automakers.
