Foil elements capable of generating lift forces and converting such forces into rotational movement of a body are suspended and submerged in a flowing stream or fluid current. Control means are provided to cyclically regulate the angles of attack of the foil elements in relation to the fluid current and to maintain substantially constant lift forces throughout a rotational cycle. Power take-off and/or generating means is included in the system.
