ABSTRACT:
A wave-actuated power generating apparatus comprising an impulse-type water turbine mounted for rotation on an upright output shaft within a housing. The housing includes a back panel and opposing sides and upper and lower surfaces which form an inlet water nozzle. The water nozzle is oriented to face oncoming waves and to direct them into the housing. A wave splitter directs a portion of each oncoming wave directly against the facing surfaces of the water turbine blades, while another wave portion is directed first against the back panel of the housing and, thereafter, against the facing surfaces of the blades. Each wave portion is redirected arcuately forwardly through about 180 degrees inwardly toward the central portion of the housing causing the water turbine to rotate. Thereafter, the water within each wave entering the housing is discharged downwardly through a water outlet positioned in the housing lower surface behind the wave splitter. By this arrangement of wave splitting, a more uniform and extended wave pulse per wave for rotating the water turbine to produce power is effected.
