摘要： A wind turbine blade (16) has a suction side surface (20) and a pressure side surface 922). A plurality of vortex elements (34) are formed on at least one of the suction side or the pressure side surfaces. The vortex elements (34) have a semi-hemispherical crescent shape with a concave wind face (40) and a convex slip face (44), with the wind face and slip face meeting at an arc-shaped ridge (42).

摘要： The invention relates to a rotatable energy generation unit for generating electric energy from a water flow, comprising: a water turbine (2); an electric generator (3), driven by the water turbine; a carrier body (5), wherein a first axis (11) is associated therewith; a nacelle body (4), with which a second axis (12), which is angled toward the first axis, is associated and which is moveable relative to the carrier body; a connecting cable (7), extending from the electric generator through the nacelle body to the carrier body; a joint connection (6) between the carrier body and the nacelle body with a device, which transmits a rotational movement of the nacelle body about the first axis (11), which is associated with the carrier body, into a rotational movement of the nacelle body about the second axis (12) assigned therewith, so that the twisting of the connecting cable (7) is limited.
