A tidal generator apparatus and method of use is described. The apparatus comprises a pair of contra-rotating vane assemblies configured to be disposed in a tidal flow stream, and having with an axis of rotation arranged substantially perpendicularly to a flow direction of the tidal flow stream. A vertical axis is preferred. Each vane assembly comprises a plurality of vanes cyclically movable during rotation of the vane assembly. The vanes move between a first extended position, and a second retracted position. In preferred embodiments, first and second vane assemblies of the pair are located sufficiently close to one another in an axial direction of the apparatus such that the plurality of vanes of each vane assembly intersects a plane perpendicular to the axis of rotation of the apparatus when in their extended positions. |
