Solar storage Engineers at MIT, Georgia Institute of Technology, and the National Renewable Energy Laboratory designed a system to store renewable energy in vast amounts and deliver it back to the grid when power generation is low. The system stores excess electricity from solar or wind installations as heat using tanks of white-hot molten silicon, and then converts the light from the glowi... » read more

Cybersecurity Check Point Software Technologies reports that facsimile machines (yes, people still use them!) can be subject to hacking through vulnerabilities in their communication protocols. The HP Officejet Pro All-in-One fax printers and other fax machines can be compromised with a hacker only knowing a fax number, according to the company. Check Point Research says a design flaw in Andro... » read more

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

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
