Opinion: Are "school of fish" turbine arrays a red herring? By Mike Barnard July 23, 2013 John Dabiri has hypothesized and tested counter-rotating arrays of vertical axis wind turbines based on fish ...

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 ...

EPFL researchers developed optimal pitch profiles for vertical-axis wind turbines using a genetic learning algorithm. The new pitch profiles resulted in a 200% increase in turbine efficiency and a 77% ...

Propeller wind turbines are the most common way of using one of the most abundant energy sources on Earth to generate electricity. The tall three-bladed fans are the ubiquitous symbol of wind energy, ...

The awareness of a greener future and its benefits is getting all the right attention in Europe. With the current climate conditions and with energy bills skyrocketing, every other person in the ...

Offshore wind turbines are trying to reproduce at sea what works on land, write Maurizio Collu & Michael Borg. But it's proving a costly and high maintenance exercise. It's time to switch to new ...

Norwegian startup company World Wide Wind (WWW) has unveiled designs for floating vertical axis wind turbines (VAWTs) for offshore wind farms to generate renewable energy. The turbines feature two ...

Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been ...
