Abstract:
1. An apparatus for extracting power from waves, the apparatus comprising: at least one pair of buoyant body members coupled to one another by a coupling which permits relative rotation between the buoyant body members about first and second non-parallel axes of rotation; a power extraction system comprising first and second pairs of power extraction elements, each power extraction element having a first end directly attached to a first of the buoyant body members and a second end directly attached to a second of the buoyant body members such that the power extraction element resists and extracts power from the relative rotation between the buoyant body members; wherein the first and second pairs of power extraction elements are respectively located either side of the first axis of rotation and are symmetrical with respect to the second axis of rotation; and wherein a lateral distance between the first pair of power extraction elements is less than a lateral distance between the second pair of power extraction elements.
