摘要： A method of and apparatus for generating electricity from ocean waves (10) by utilizing a float (110) with excessive buoyancy; the basic arrangement and principle utilizes a float (110) with excess buoyancy which exerts a primarily upward buoyancy force on the float (110) along a direction perpendicular to the isobaric surfaces of the ocean waves (10) which changes as the ocean waves (10) propagating through the water body; a holding device (120) is used to hold the float under the ocean surface, which exerts a primarily downward holding force on the float (110) while allowing the float to move back and forth in a substantially horizontal direction as a result of a substantially horizontal force which is a combination of the holding force and the buoyant force; a turbine (142) is attached to the float (110) or the holding device (120) for generating electricity as the float (110) moves back and forth in the liquid body.
