NuVo Technologies is sure proud of its new Essentia E6G whole home audio system, but rather than waxing rhapsodic about its lengthy list of features, it chose to boast about its newfound Energy Star rating. Aside from the being an apparent power sipper, the E6G also touts Philips Class D digital audio amplification (40-watts per zone), an RS-232 bidirectional control interface, 1U rack height, a newfangled control pad, OLED display and support for six sources and an equal number of zones. Of course, we sure hope you save a few dollars on that energy bill if you plan on picking this up, 'cause you'll be shelling out $2,299 up front before ever plugging it in.
Mark this down as a little out there, but a new Marvell chip claims to improve the efficiency of desktop and laptop power supplies by determining and then optimizing the amount of energy each particular application needs. Named a "power factor correction controller," the chip enables computers to comply with new Energy Star guidelines that require computers to use at least 80 percent of the energy supplied to power them. It's not the only chip out there that claims to improve efficiency using this method, although Marvell has already started producing the chips with the aim of hitting full volume production in Q1 2008, and seeing them in PCs thereafter.
