Power/Performance Bits: Feb. 20

Wireless TENG Researchers at Clemson University developed a wireless triboelectric nanogenerator, or W-TENG, that can also act as a battery-free remote. The key to triboelectric nanogenerators is using materials that are opposite in their affinity for electrons so they generate a voltage when brought in contact with each other. For the W-TENG, one electrode was constructed of a multipart... » read more

Greener greenhouses Researchers at the University of California, Santa Cruz are testing greenhouses capable of generating some of their own energy, without hampering plant growth. Greenhouses use electricity to control temperature and power fans, lights, and other monitoring systems. Electricity-generating solar greenhouses utilize Wavelength-Selective Photovoltaic Systems (WSPVs), a novel ... » read more

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

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
