<p>An improvement for a wave energy converter comprises a substantially rigid skirt (10) adapted to be suspended from a wave energy converter below the surface of the water. The skirt (10) comprises an elongate substantially cylindrical structure (12) extending vertically so as to form a flow path for water particles over a surface of the structure. The cylindrical structure (12) comprises a series of rings (14) of substantially equal diameter arranged concentrically at spaced vertical intervals. The curved surfaces formed by the circular cross-section of the rings (14), form an undulating flow path for water particles travelling in a vertical direction. In this way the vertical component of the wave energy extracted from the wave's circular water particle motion can be maximised.</p> |
