Unidirectional water turbine with guides to accept flow from any direction

摘要

A device for generating energy from water flow such as tides or waves has a vertical axis turbine, and flow guides shaped to ensure that the water always rotates the turbine in the same direction. The guides may be arranged in a square arrangement so that water flow from any direction drives the device. The flow guides may be funnel shaped and there may be gates E to allow the device to be closed. The device may have a concrete base and be built on the sea floor. A number of devices may be arranged in a dam to form a breakwater or barrage. The device may also be used in a river where it may only two openings to accept river flow (figures page 3).
