(JP9506951-W)      The wave energy transformer includes containers (37,38) which are interconnected by a conduit (15) through which gas trapped in the open bottomed containers is transferred to drive a generator. The containers have vertical tubes (41) connected to their tops (40) and pierced with apertures (42). The containers can move vertically on guides (43) along upright pillars (44,45).    The apertures (42) are automatically closed to prevent water from entering the gas transport conduit. It is advantageous if the walls of the containers are at least partly formed from flexible material. Gas tight membranes can be employed to separate water from gas in the containers.    USE/ADVANTAGE -   Sea bed equipment gives high performance wave swell energy extension.
