IMPROVEMENTS IN OCEAN WAVE ENERGY EXTRACTION

摘要

591329 Disclosed is an ocean wave energy extraction system. The system has at least one duct (203) for receiving an oscillating water column, the ducts (203) having a first segment, a second segment arranged transversely to the first segment and a flow control segment (207) intermediate the first and second segments. The flow control segment (207) has a sloped portion which inhibits turbulent flow of the oscillating water column flowing within the duct (203), the sloped portion having a planar surface extending between the first and second segments. An air-driven turbine (216) is in fluid communication with the second segment of the duct (203), the turbine (216) being driven to rotate unidirectionally by a bidirectional airflow generated by oscillations of the oscillating water column within the duct. An electric generator is configured for rotation by the turbine (216) to generate electrical energy.
