Airborne Turbine for Remote Sites

Written by , on October 2, 2014

Winds 300 to 600 metres above the ground are, on average 5 to 8 times as strong as those at the surface.

Altaeros, a four-year-old company in Massachusetts, has developed its Buoyant Airborne Turbine (BAT) to take advantage of these stronger, more consistent winds.  Read more »

New Wind Turbine Design Based on Bird Wings

Written by , on April 15, 2014

The German industrial automation and control company, Festo, has developed a dual wing generator. In contrast to conventional small wind power stations, the system uses two pairs of opposing wings instead of rotor blades to generate power.  Read more »

Drones to Collect Solar and Wind Energy

Written by , on February 12, 2014

New Wave Energy, an English company, has plans to build a high altitude aerial power plant, consisting of networks of unmanned drones that can harvest solar and wind energy and transmit it wirelessly to receiving stations on the ground. As sunlight radiates down to the Earth's surface some of its energy is absorbed into the […]  Read more »

Ship Design Uses Hull as Sail

Written by , on September 12, 2013

The Norwegian speed sailor and inventor, Terje Lade, has developed a new concept for a ship in which the hull acts as a giant sail. He estimated that the “Vindskip” would have fuel savings of 60% and emissions reductions of 80% compared to current cargo ships. The Vindskip would have natural-gas fired engines and a […]  Read more »

Study: Nearby Wind Turbines Do Not Effect House Values

Written by , on September 7, 2013

The California Lawrence Berkeley National Laboratory has conducted an analysis of more than 50,000 home sales near 67 wind facilities in 27 counties across nine U.S. states. The study found no impact of nearby wind turbines on home property values. Ben Hoen, the lead author of the report, said that “This is the second of […]  Read more »

World’s First Wind/Current Generator

Written by , on August 2, 2013

Mitsui Ocean Development and Engineering Company has developed the world’s first hybrid wind and marine current generator. The device consists of a floating, vertical axis wind turbine with a “keel” made up of a current turbine. The omnidirectional Darrieus wind turbine.rotates regardless of the wind direction. The generator is located at the base of the […]  Read more »

Hybrid Solar-Wind Turbine

Written by , on July 12, 2013

SME McCamley Middle East Ltd, togeher with engineers at the University of Bath, have developed a new hybrid technology that integrates wind and solar power generation – the wind turbine blades are encased in an outer frame, which is topped with solar cells. The turbines are designed to be mounted on buildings and in built-up […]  Read more »

Storing Offshore Wind Energy

Written by , on April 30, 2013

Researchers at MIT have proposed a method of storing the energy generated by offshore wind farms using concrete tanks on the seafloor under the wind turbines Their concept is to place spherical concrete tanks, about 25 metres in diameter, on the seafloor under floating wind turbines. The concrete tanks would serve both as anchors to […]  Read more »
