Two MSc students, Nicolas Orellana and Yaseen Noorani,  at Lancaster University, have developed a rotating wind turbine which, unlike conventional wind turbines, can take advantage of both horizontal and vertical winds without requiring steering.

Conventional wind turbines only capture wind travelling in one direction, and are notoriously inefficient in cities where wind trapped between buildings becomes unpredictable.

The new O-Wind Turbine spins when wind hits it from any direction. The turbine is a 25cm sphere with geometric vents siting on a fixed axis. When wind energy turns the device, gears drive a generator which converts the power of the wind into electricity.
