A tidal power generator comprises a float 4 which is partly filled with water 2 and partly with air 1. The float is therefore ballasted and transmits force as it moves due to the tide during both rising and falling. The force may be used to generate electricity, compress air, or to drive a reverse osmosis desalination unit. The water and air may be held in separate containers, and the container, or part of the container which is filled with water may be further subdivided to provide baffles which limit undesired movement of the ballast water. The use of water as ballast avoids the need to transport and install heavy weights as the chamber(s) may be flooded on site. |
