Optimum use of wave energy using oscillating water column system

Engineers Modesto Amundarain and Mikel Alberdi have presented the first two PhD theses at the University of the Basque Country (UPV/EHU, Spain) on the use of oscillating water column (OWC) converters for extracting renewable ...

Upgrading the vanadium redox battery

Though considered a promising large-scale energy storage device, the vanadium redox battery's use has been limited by its inability to work well in a wide range of temperatures and its high cost. But new research indicates ...

Smart meters raise suspicions

Coast to coast, from Maine to Marin County, Calif., the number of homes being outfitted with smart meters that keep a close eye on homeowner electricity use is on the rise. And so is the number of folks who think smart meters ...

Higher energy yield with torque vectoring gears

Wind turbines have a problem: Depending on the wind's force, the rotational speed of the turbine and thus of the generator changes. However, alternating current must be fed into the grid with precisely 50 (or 60) hertz. Typically ...

Space weather could wreak havoc in gadget-driven world

A geomagnetic space storm sparked by a solar eruption like the one that flared toward Earth Tuesday is bound to strike again and could wreak havoc across the gadget-happy modern world, experts say.

Huge solar flare jams radio, satellite signals: NASA

A powerful solar eruption that triggered a huge geomagnetic storm has disturbed radio communications and could disrupt electrical power grids, radio and satellite communication in the next days, NASA said.

'Smart grid' would save energy, cut costs for US consumers

Momentum is building for a new energy "smart grid" that would overhaul the U.S.'s 100-year-old electrical power network. The impact would be huge –– from installation of a new web of electrical transmission lines ...

Study gathers comprehensive wind info to improve renewable energy

Meteorological equipment typically used to monitor storms could help power grid operators know when to expect winds that will send turbine blades spinning, as well as help them avoid the sudden stress that spinning turbines ...
