Abstract

A wind turbine blade comprising a curved frame supporting a tensioned membrane. Also claimed, is a vertical axis wind turbine comprising a mast and a rotor, wherein the rotor comprises a central hub and multiple arms 7 radiating from the central hub with a blade attached to each arm. Each blade comprises a curved frame supporting a tensioned membrane 8, wherein the outer ends of adjacent arms or adjacent blades are linked by stays and/or struts. Preferably each arm is attached to the frame of the blade on two opposite sides and the frame comprises arced ribs 10. There may be a vertical drive shaft coupled to a generator or pump at or near ground level and the mast may comprises a joint which allows the mast to be rotated between an erected position and a lowered position. A method of constructing a blade and erecting a mast are also claimed.
