ABSTRACT:
A wave energy conversion system is disclosed and comprises a spine and a plurality of wave driven pump units each comprising a pillow shaped flexible bag arranged with its length direction horizontal and mounted on the spine so that the water in which the system is located flows to both sides of the bag so that in use the bag is kept out of abrading contact with the spine. The lower edges of the bags are attached to the spine and the upper edge of each bag has a common outlet/inlet passage through which air is pumped back and forth by the bag collapsing and expanding under the influence of the waves. The common passage is at one top corner of the bag and at the other top corner is a dummy passage which enables the bag to be fabricated in such a manner that the corners are not stressed significantly in use. Also, a common pipe can be used to define the common passage of one bag and the dummy passage of the adjacent bag. The pumped fluid from each bag is passed through a module which is located outside the spine and therefore can be easily removed for repair, the module including a uni-directional turbine for converting the fluid energy into shaft/electrical energy.
