Abstract
An improved ocean wave energy extraction system is disclosed. The system includes at least one duct for receiving an oscillating water column. The duct has a first segment, a second segment arranged transversely to the first segment and a flow control segment intermediate the first and second segments. The flow control segment is configured to inhibit turbulent flow of the oscillating water column flowing within the duct. A turbine is in fluid communication with the second segment of the duct such that the turbine is driven by the fluid flow which is generated by the oscillations of the oscillating water column within the duct. The turbine rotates an electric generator to thereby generate electrical energy.
