ABSTRACT:
A rigid waterproof structure built on the ocean floor near a shore is completely enclosed. Guides are provided to direct the waves or swells from the ocean to an inlet opening which is completely covered, by a free-hanging heavy gate which latter is opened when the waves or swells move toward the shore thereby introducing water into the dome-like structure and displacing the air therein, thus compressing it. The air is forced out through check valves and thus compressed is conducted to a storage tank for the compressed air. Air intakes are provided which are closed when the air is compressed in the structure and are opened when the water escapes from the structure. As the waves are receding from the shore the free-hanging gate is drawn over the inlet opening and closes the same, and a device, in this form cables over pulleys connected to the free-hanging gate and to gates covering respective outlets, pulls the gates open thereby letting the water escape from the structure behind and outside the guide walls instead of the same way it entered and thereby not interfering with the next incoming swell or wave.
