The CETO is an Australian invention and it is a fully submerged system
that sits on the seabed. The wave crests cause a disc to move down, but it will rise again during the trough. The vertical motion of the disc is
used to drive two pumps in order to produce high pressure water (in
excess of 6 400 kPa). The water is pumped to shore through a 125mm
pipe where it is used to drive a generator in order to produce electricity
or it can be used to produce fresh water through reverse osmosis.
