China cuts 2012 rare earths export quota
(AP) -- China announced a cut Tuesday in its rare earths export quota as it tries to shore up sagging prices for the exotic metals used in mobile phones and other high-tech goods.
Wind turbines that learn like humans
Depending on the weather, wind turbines can face whispering breezes or gale-force gusts. Such variable conditions make extracting the maximum power from the turbines a tricky control problem, but a collaboration of Chinese ...
Japan finds rich rare earth deposits on seabed
Japanese researchers said Thursday they have found a rich deposit of rare earths on the Pacific seabed, with reports suggesting it could be up to 30 times more concentrated than Chinese reserves.
Oil drilling technology leaps, clean energy lags
Technology created an energy revolution over the past decade—just not the one we expected. By now, cars were supposed to be running on fuel made from plant waste or algae—or powered by hydrogen or cheap ...
When the wind blows: New wind energy research focuses on turbine arrangement, wind seasonality
(Phys.org) —Research into the best ways to arrange wind turbines has produced staggering results—quite literally.
Mars tech electrifies Earth
Some of the wind turbines generating electricity on Earth today grew out of technology developed in the 1990s for settlements on Mars.
Localized wind power blowing more near homes, farms and factories
Americans are increasingly installing wind turbines near their homes, farms and businesses to generate their own energy, concludes a new report released today.
Shifting winds in turbine arrays
Researchers modeling how changes in air flow patterns affect wind turbines' output power have found that the wind can supply energy from an unexpected direction: below.
Norwegian energy groups to build new British wind farm
Norwegian energy companies Statoil and Statkraft said Tuesday they will build an offshore wind farm in Britain with 67 turbines that will eventually power over 400,000 homes.
An autopilot for steering flying windmills
The idea of using kites to collect the energy produced by high altitude winds has been gaining ground amidst the scientific community. EPFL researchers have developed an autopilot device to control and optimize ...
Smart anti-icing system for rotor blades
In very cold climate zones, the wind can blow with tremendous force. But wind turbines have rarely been built in these regions up to now. The risk of ice formation on the rotor blades is just too high. But ...
Gold rush-era discards could fuel cellphones, TVs (Update)
(AP)—Across the U.S. West, early miners digging for gold, silver and copper had no idea that one day something else very valuable would be buried in the piles of dirt and rocks they tossed aside.
Turning plastic bags into high-tech materials
University of Adelaide researchers have developed a process for turning waste plastic bags into a high-tech nanomaterial.
Lifting mechanism for mounting huge rotor blades
Siemens has created a special mechanism for mounting its 75-meter-long rotor blades for offshore wind farms. The lifting system makes assembly work safer and lets construction take place at higher wind speeds ...
