Scientists spark new interest in the century-old Edison battery
Stanford University scientists have breathed new life into the nickel-iron battery, a rechargeable technology developed by Thomas Edison more than a century ago.
Superconductor 'flaws' could be key to its abilities
(Phys.org)—Many researchers studying superconductivity strive to create a clean, pure, perfect sample, but a team of physicists found that some flaws might hold the key to a material's unique abilities.
Floating wind turbines bring electricity where it's needed
It's a balloon that lifts a wind turbine. That's the easiest way to describe the technology being developed by Altaeros Energies, led by Ben Glass, inventor and CEO of the young company. Glass has reimagined ...
Engineers study the benefits of adding a second, smaller rotor to wind turbines
Hui Hu picked up a 3-D printed model of a typical wind turbine and began explaining two problems with the big, tall, three-bladed machines.
New study reveals unexpected disappearance of superconducting fluctuations at super-cold temperatures
(Phys.org)—The next generation of sustainable energy systems, from magnetic storage to offshore wind turbines, hinges in part on high-temperature superconductors (HTS), which can carry current with zero ...
Wind farms perform best when the sun is out
When set up in groups, wind turbines in the front rows cast a wind shadow on those behind them, lowering their performance. These effects dissipate fastest under convective conditions, say EPFL researchers ...
Engineer says 'smart grid' needed for shift to alternative energy
(Phys.org) —Electrical grids are balky beasts, and nobody knows that better than Stanford Assistant Professor of Civil and Environmental Engineering Ram Rajagopal. He grew up in Brazil, where no one took ...
UK wind power share shows record rise
The United Kingdom wind power production has been enjoying an upward trajectory, and on Tuesday wind power achieved a significant energy production milestone, reported Brooks Hays for UPI. High winds from Hurricane Gonzalo were the force behind wind turbines outproducing nuclear power ...
Denmark champions wind power, sets record
October was 'bumper' month for Scotland's renewables
Study suggests real-world generating capacity of wind farms at large scales has been overestimated
Research by Harvard professor David Keith suggests that the global capacity for energy generation from wind power has been overestimated, and that geophysical / climate effects of turbines will reduce the ...
France to build wind farm with stealth turbine blades
Just how green is wind power?
Wind power may have a positive image, but setting up offshore wind farms is complicated and energy-intensive. Because Siemens promises its customers and the authorities a high degree of transparency for the ...
Wearable tech for the battlefield and people at risk for heart attacks
Wearable devices can count the steps you take and the calories you burn. But can they help soldiers in the field? Or prevent someone from having a heart attack?
