A wind or water turbine, eg a vertical-axis wind turbine (VAWT), comprises a first member which is rotatable about a first axis of rotation, and one or more vanes 601, 602 … each of which is (i) mounted on the first member; (ii) rotatable with respect to the first member; and wherein (iii) the mounting point of each vane is radially spaced away from the first axis of rotation. The axis of rotation of each vane may be parallel to that of the main member. The rotational position of each vane 601, 602… is defined by the rotational position of the first rotating member, eg using planetary gearing (figs. 7,8), such that such that as the first member rotates in a first direction each vane 601, 602… rotates in proportion to this movement in the opposite direction. Electricity may be generated, eg using magnets and coils. The turbine may be controlled by a weathercock or anemometer.
