Abstract

A vertical-axis wind turbine (1) comprising a rotor (2) which has a frame (3) which can rotate about a rotation axis (3a) which is substantially vertical and supports at least one vane array, which lies circumferentially around the rotation axis, the vane array (5) comprising a plurality of vanes (6) which are mutually angularly spaced and distributed along an annular region which is substantially concentric with respect to the axis of rotation (3a).
