More Information
Summary:A wave energy device comprises at least one open-ended tube 1,9,10,11 for insertion into a body of water and a power conversion and pressure control module 4, which may include a pneumatic turbine, blower, exhauster or latching valves for adjusting the pressure of a fluid in the tube, such as air (3, Fig 1) or a liquid less dense than water (18, Fig 8), and thus adjust the mean water level within the tube 1,9,10,11. Power from the flow of fluid 3 caused by waves passing the device may be harnessed by a power converter, such as a cross-flow radial turbine (25, Figs 5c-e). The tubes 1,9,10,11 may be of different lengths (Fig 5) or be telescopically adjustable (6, Fig 3) and may be straight or helical.
