Vertical axis wind turbine

Abstract

The present invention provides a shroud for a vertical axis wind turbine. The shroud is configured in use to externally surround a rotor of a vertical axis wind turbine. The shroud comprises: upper and lower axially spaced apart supports, configured in use to be respectively positioned above and below the rotor, and each support has a radially outer periphery defining a polygonal shape with a plurality of circumferentially distributed corners. The shroud comprises a plurality of circumferentially distributed stators each extend longitudinal between a corner of the upper support and a corner of the lower support such that adjacent pairs of stators and the interposed sections of the outer periphery of the upper and lower support define a plurality of quadrilateral frames configured in use to circumferentially surround the rotor.
