A vertical axis wind turbine (1) comprising a turbine rotor having an axis of rotation and at least one blade (2) spaced from and mounted for rotation about the rotation axis of the turbine. The blade has at least one longitudinal surface substantially parallel to the rotation axis and for engagement, in use, with wind incident on the turbine rotor. The blade is a two part blade with a first leading blade portion (7) pivotably connected to a second trailing blade portion (8). The turbine includes pitch control means and camber control means for controlling the pitch and camber of the blade. The pitch control means is a pivot on the first leading blade portion, with the pitch pivot (24) being guidable along a pitch path defined by a first physical pathway component (10), and the camber control means is a camber pivot (27) on the second trailing blade portion, the camber pivot being guidable around a camber path defined by a second physical pathway component (11). |
