Underwater Kites Harvest Energy From Tidal Currents

read
Minesto's 'Deep Green' tech starts producing electricity

A kite-like tidal power device off the coast of Northern Ireland has begun producing electricity. The technology, called Deep Green, consists of a hydrodynamic wing and a turbine tethered to the ocean floor. The tether also contains the unit's power and communication cables. As water flows over the wing, the turbine rotates and generates electricity. In an offshore control room, located in the......read more

Invention Harvests Electricity from Background Radiation

read
Device could be used to beam power to remote locations or recharge phones wirelessly

Engineers at Duke University have designed a gadget that captures background radiation and converts it to useable electricity. Operating on the same principle as solar panels that capture light energy, the "metamaterial cells" can harvest microwaves with an efficiency of 36.8 percent -- the same efficiency as modern solar cells. The Daily Mail reports: The development raises exciting......read more

Monovolume Architects: Punibach Hydroelectricity Station

read
An alpine hydro plant embedded into the hills of northern Italy

Conceived as a fracture in the landscape, monovolume's Punibach hydroelectric power station is harmonically integrated into its alpine surroundings. A concrete slab separates the smooth hilly landscape and the raw building structure made out of natural, earth coloured materials. At night, the thin wood planks that form a lamellar wall allow warm light from the interior to glow in......read more

Offshore Wind Gains Momentum

read
More and more countries are tapping powerful ocean winds for electricity

Wind power may be the leading source of renewable electricity (apart from hydro), but we haven't even scratched the surface of its true potential. Of the 238,000 megawatts of wind capacity installed at the start of 2012, just 4,600 megawatts came from offshore wind farms. On a planet that's two-thirds water, that leaves plenty of room for improvement. But, according to a new Earth......read more

Central America's Geothermal Potential

read
Region beginning to tap seismic volatility for electricity needs.

The entire length of Central America is dotted with active volcanoes, a geographic fact that can have disastrous consequences for people in the region. But it also presents a positive opportunity, in the form of geothermal energy potential. And it's beginning to be realized. Geothermal power plants harness energy from water that is heated by molten rock beneath the volcanos. A reliable......read more

The Electric Car Dilemma

read
