This is a modified Subwave turbine (3) laid sideways and equipped with floating elements (light shade) around the hollow shaft running through the entire turbine, giving the turbine a strong, positive buoyancy (4). A winch on each of the two gravity anchors (6), pulls it down into and along the tidal current. The flexible turbine blades work just as well, and rotate the rotors the same way, whether the tidal current goes one way or the other. A very simple system that can be repeated sideways, and scaled freely. Will work at any depths. Top view below.
