'Nanorefrigerator' Cooled By Sunlight
Researchers in Belgium have drawn up plans for an electronic "nanorefrigerator" device that is driven by high-energy photons, and could, therefore, potentially be directly powered by the sun. The device consists of two electrodes, one of which is cooled by replacing hot electrons with cool ones via photon absorption. While this is not the first system that applies the "cooling … [Read more...]
Cooling LEDs with Air Instead of Heat Sinks
Zeta LED has developed an air-cooled LED light bulb. The Lifebulb consumes 10 watts of power and puts out as much light as a standard 60 watt incandescent, pretty much like existing LED bulbs.
