TidGen Power System
Device consists of a series of cross-flow turbine that uses a turbine design similar to the Darrieus design, but horizontal. It uses multiple rotating foils to power a gearless, central permanent magnet generator that converts the rotational energy into electricity. The device is built primarily with composite materials and corrosion resistant steel. The device is moored using either fixed bottom support frames, or buoyant tension mooring systems consisting of a buoyancy pod and tensioned mooring lines. The device is completely submerged and typically rests at or near the seafloor. The device is designed for lower current velocities. The minimum water depth is 15 m.
