Abstract:
1. A power generating apparatus suitable for use in extracting energy from the movement of water, comprising an elongate, generally circular in cross section, buoyancy vessel ( 1 ), the buoyancy vessel ( 1 ) having depending from its underside on a mounting means, a rotor ( 2 ) comprising rotor blades ( 3 ), connected to a power generating means, the rotor ( 2 ) being connected to the vessel ( 1 ) through the mounting means ( 5 , 6 ) by a hinged joint ( 7 ) in a keel section ( 8 ) of the vessel ( 1 ), so as to be movable from a first, stowed position, adjacent to and immediately below the vessel ( 1 ), to a second deployed condition spaced from the vessel and facing the direction of tidal currents, whereby movement of water across the rotor blades ( 3 ) of the rotor ( 2 ), drives the rotor ( 2 ) so as to generate power in the power generating means.
