Abstract: An oscillating water column (OWC) turbine and method of extracting energy therefrom is provided. The OWC turbine includes a shaft (101) rotatable about a central axis (103), and first and second ports (112, 114) disposed around the central axis. A flow passage (104) extends radially-inward from the ports and extends axially therebetween. Rotor blades (120) are coupled to the shaft, intersect the flow passage, and are offset from the central axis by a first distance. First guide vanes (116) intersect the flow passage and are disposed proximal the first port. The first guide vanes (116) include first and second stators (116a, b), the first stators (116a) being positioned between the first port (112) and the second stators (116b). Second guide vanes (118) intersect the flow passage and are disposed proximal the second port. The first and second guide vanes are offset from the central axis by a second distance that is greater than the first distance.
