Power/Performance Bits: March 1


Low power Wi-Fi Computer scientists and electrical engineers from the University of Washington came up with a way to generate Wi-Fi transmissions using 10,000 times less power than conventional methods and which consumes 1,000 times less power than existing energy-efficient wireless communication platforms such as Bluetooth Low Energy and Zigbee. The system, Passive Wi-Fi, uses backscatte... » read more

Power/Performance Bits: Jan. 12


Incandescent bulbs might not be dead yet Can incandescent bulbs be as efficient – or even more so – than LEDs? More than 95 percent of the energy that goes into incandescents is wasted, most of it as heat, so researchers at MIT and Purdue University struck out to see if that could be changed. A conventional heated metal filament, with all its attendant losses, served as the basis. But... » read more
