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 ...

We interviewed the core team at Norway's World Wide Wind to learn more about its floating, tilting, contra-rotating, double turbine design, which it says can unlock unprecedented scale, power and ...

Windspire's VAWTs individually perform similarly to all vertical axis turbines, at levels of efficiency below that of horizontal-axis wind turbines. They have struggled in the relatively crowded small ...

Journal of Urban and Environmental Engineering, Vol. 5, No. 1 (January to June, 2011), pp. 15-23 (9 pages) Abstract: Wind energy is a very popular renewable energy resource. In order to increase the ...

The field of renewable energy depends on innovation to create effective, sustainable solutions. Semtive Energy created the Nemoi M, which represents a significant advancement in wind turbine ...

Wind turbines attached to floating buoys can harness stronger, more sustained winds in the open ocean. But the floats now used for such deep-water installations may prove prohibitively expensive ...

CEO at Freen OU, a small wind turbine manufacturer. We're delivering sustainable energy projects across EU, Middle East, Africa & Asia. I believe that the role of renewable energy has never been more ...

Today National Geographic News published a story by Victoria Markovitz on the size and relative greeness of wind turbines. In it, she summarizes a new study by the Swiss Federal Institute of ...

Those attending the recent Windpower 2013 exhibition could get a first-hand explanation of the Looped Airfoil Wind Turbine, a concept said to overcome shortcomings of horizontal wind turbines. Devised ...
