Patent ID: 7131269

Claim:
An apparatus ( 1 ) for utilising wave energy, comprising: a body ( 2 ) shiftable under the reciprocating movement of the water mass such a forward movement of the water mass shifts the body and a reverse movement of the water mass shifts the body, means for storing the kinetic energy of the body into an energy reserve ( 3 ), and means for transferring energy from the energy reserve ( 3 ) to the object of application, wherein, the body ( 2 ) is fastened to the bottom of the water basin, at an intermediate water depth where the movement of each point of the water mass ( 5 ) is substantially reciprocating around a given centre, the body is fastened to the bottom of the water basin so as to be completely immersed in water, and the apparatus ( 1 ) is immersed totally under the water except for the means for transferring energy from the energy reserve ( 3 ) so that at least the body and the means for storing the kinetic energy of the body are immersed totally under the water.
