Abstract
The submerged electricity generator includes a vertical cylinder (1) open at the top with a piston moving vertically. The upper surface of the piston is subject to the varying pressure of the waves, whilst the lower surface is subject to atmospheric pressure because of a vent pipe (3). Two counter-poise weights (4, 5) are attached by cables or chains (6, 7) and pulleys (8, 9) to the piston. As the piston moves up and down under the effect of the waves, the weights also move. They serve as the mobile parts of two linear electric generators with fixed coils (11, 12). The coils provide an output of electricity. A system of jacks (15, 16) is provided for raising or lowering the whole generator structure.
