Abstract

A method of extracting energy from waves in a body of water comprises (a) locating a flexible pipe such that it floats on a body of water in a substantially fixed position relative to the direction of wave travel and such tat at least an initial part of the pipe extends substantially in line with the direction of wave travel, wherein the pipe is arranged to flex up and down with the waves such that the pipe has a wave form corresponding to the surface of the body of water, (b) allowing water into the pipe such that it can be caused to advance along the pipe as the pipe flexes with an advancing wave front; (c) allowing said water to be advanced along the pipe by a wave front; and (d) employing water which has travelled along the pipe in an application which requires the use of water having kinetic energy. The invention provides a simple method for use in extracting energy from waves which overcomes at least one problem associated with known methods. The invention also provides an apparatus for carrying out the method.
