Apparatus for extracting energy from water waves

摘要

Apparatus for extracting energy from water waves includes an elongate water wheel mounted rotatably so that at least a portion of the wheel is above the level of the water, and a ramp extending substantially the length of the wheel to shield the wave side of the wheel from wave impact and to direct water of the wave upwardly over the top of the wheel so as to impact the water wheel on the side thereof removed from the wave and effect rotation thereof. A holding tank is preferably provided at the top of the ramp and above the wheel to hold water from the waves and to direct it onto the wheel. Energy may be extracted from the rotating wheel by a generator or other device.
