Wind energy is becoming highly popular in the area of renewable energy, with wind energy being forecast to provide up to 8% of the world’s consumption of electricity by 2021. Advancements in wind ...

From huge kites to sea-bound flywheels and roof-top installations to tree-like art creations, we've seen many different approaches to capturing energy from the wind. One design, though, reigns supreme ...

Counter-rotating wind turbines (CRWTs) represent an innovative paradigm in wind energy conversion, employing a dual rotor mechanism in which two coaxial rotors spin in opposite directions. This ...

A wildly innovative turbine that could halve the cost of offshore wind is set to go into testing in Norway. The 19-m (62-ft), 30-kW, contra-rotating vertical-axis turbine is a prototype of a design ...

Wind turbine rotor blades are a high-technology product that must be produced at moderate cost for the resulting energy to be competitive in price. This means that the basic materials must provide a ...

Drag-based wind energy design. Aiming to translate its expertise in manufacturing monocoque, ribbed components with thermoplastic microspheres, Xenecore is working to develop a fan-shaped, drag-based ...

Wind power generation in the U.S. is enjoying favorable winds. First, the cost of wind turbine installations has dropped by over one-third since 2010 as the capacity of turbines increased. Next, ...

The Darwind5 Trekker series of portable wind turbines are billed as next-generation Darrieus "eggbeater" powered generators. The design is said to deliver 35% better annual power production than any ...
