ABSTRACT:
Apparatus for deriving power output from wave energy is disclosed. A rotatable member is provided which is capable of rotating in only one direction. A float is provided which rises and falls in response to wave action, and thereby moves relative to the rotatable member. The float is coupled to the rotatable member so that the movement of the float rotates the rotatable member in its available direction to provide power output.
In its preferred form, the present invention provides an elongate floating barge flanked by a pair of elongate floats. Transverse movement of the floats relative to the barge is limited. A rotatable power output shaft is mounted on the barge parallel to the elongate floats. A plurality of pulleys circumscribe the shaft and are spaced along its length. Tension members attached to the floats circumscribe the respective pulleys to rotate the pulleys and thereby the shaft as the floats move relative to the barge to achieve power output.
