The invention relates to a wave power device 1 for the extraction of energy from waves in a liquid 3. The device 1 comprises a container 2 intended to at least partially be located in the liquid 3 from which the wave energy shall be extracted. The container 2 is provided with one or several openings 6, for admitting said liquid 3 and gas 5 into the container and at least one outlet 8. The container 2 is at least partly designed as an oblong unity adapted to be influenced by and essentially follow the wave motions in the liquid 3 so that the container 2 assumes a wave shaped contour. The container 2 will assume positions having different potential energy relative each other in at least a first portion 9 and a second portion 10. By the wave motion will liquid 3 and gas 5 be transported through the tubular container while a pressure is built up within the container 2. The invention is in particular directed to the design of the container 2 which shall be designed so that it is along at least a portion of its length its width B is larger than its height a in order to reduce friction losses in the plant considering practical limitations in allowable height of the container in relation to wave height. |
