ABSTRACT:
An improved method and system for generating power, more particularly, electrical power, from the wave motion of a large body of water. A central tower, closed at the top, which supports a substantial head of water above the mean water level of the large body of water, has at least one, and preferably a large number of, conduits connected between the top of the tower and a level between the high and mean liquid level of the body of water. Periodic wave motion washing over their lower ends builds up water pressure in the conduits, causing flow to the top of the tower, which causes a constant flow down through the tower. A turbine mounted in a Venturi constriction at an intermediate level in the tower is driven to rotate by the downward flow of water, causing a generator to produce electricity. In one embodiment, the primary tower is based on shore with an outlet to the sea. In another embodiment, the tower is supported on the sea floor, and is surrounded by a breakwater for minimizing wave action adjacent the tower.
