ABSTRACT:
A plant, generator and rotating member for the production of power from currents in a body of water, comprising a fixedly mounted of floating structure, and a plurality of replaceable generator units (750) supported by the structure and which are driven by the water currents. The structure comprises arms (615, 720, 730). The rotating member (400) comprises a plurality of member sections (410) rotatably mounted on a shaft (405) between an end piece (407) and a tip (406). The generator comprises a contra-rotating rotor (550) and stator (800) connected to respective shafts (500, 820) and bearings, where the stator frame (800) is axially supported (810) on the first shaft (500) and the first shaft (500) at one end thereof is axially supported (810) on the stator frame. The generator according to the invention can be used for the production of electric power, and as an electromotor for the production of mechanical rotational energy.
