Abstract

The present invention includes novel apparatus and methods for recovering energy from water waves. An embodiment of the present invention includes a buoy, a shaft, and an electric power generating device. The shaft is coupled to the buoy such that when the buoy moves vertically in response to a passing wave, the shaft rotates. The shaft is coupled to the electric power generating device such that when the shaft rotates, the generating device produces electric power. Once electric power is generated, it is delivered to shore, where it is stored, used to power a device, or delivered to a power distribution grid.
