Abstract
An open ended tube is mounted in fixed, vertical orientation within a body of water with the top and bottom ends of the tube at preselected depths relative to a mean water level when preselected waves with which the invention is designed for use are present. The tube top open end is disposed at a first depth approximately equal to but not less than the maximum preselected wave amplituded so that the top end is always submerged. The tube bottom open end is disposed at a depth where the energy level associated with preselected waves of maximum wavelength is small. In response to pressure variations caused by passing waves, water flows into and out of the tube, and energy capturing means, e.g., a piston or turbine, is disposed within the tube for converting the water flow to useful energy.
