<p>A wave energy extraction device (Fig. 2b) for converting wave energy into mechanical motion is curved in the horizontal plane via a connection (16). A concave side (11) facing the incoming waves increases energy capture and a convex side (12) on the lee side to reduce energy dissipation. The concave surface is substantially parabolic or semi-elliptical and the convex side is optionally provided with a substantially Gaussian profile (4) to improve the hydrodynamics and additional strength. To simplify connection to flexible coupling (18) to a base platform (19) the paddle curvature tapers to a straight edge (1) at the mounting points and the base device can be located either above or below the water surface. One embodiment is also curved about a vertical as well as the horizontal plane to create a spoon- or cup-shaped paddle.</p> |
