Abstract: This hydropneumatic wave power generator, converts the waves, vertical surface displacements into usable electrical or mechanical energy. A fixed cylinder with an open bottom is suspended above the ocean floor in a fixed position. The cylinder top is tightly enclosed except for a “T” shaped air tube opening into the cylinder chamber. This “T” tube houses an intake unidirectional valve on one arm and an exit valve on the other. An intake air tube open to the air and passing through a flywheel equipped air turbine connects to the intake arm of the “T” tube. An exit air tube connected to the exit arm of the “T” tube is likewise connected to the same turbine before it exits to the atmosphere. Air within the wave chamber, above the water, is pushed by a rising wave through the exit valve into the exit tube, which drives the turbine blades to which it is connected.

Abstract: A waterwheel made up of a number of parallel narrow circular bands, connected by spokes to a central metal axel, which is in turn mounted to a boat hull on bearings. The axel is oriented perpendicular to the long axis of the keel line. Alternative to the parallel circular bands, a narrow spiral band, supported by a central metal ring and two lateral rings is also presented. Making the supporting rings of similar size simulates a flat surface of support, while making the central ring larger than the lateral support ring simulates a “V” shaped surface of support. These narrow circular or spiral bands tend to slice through the waves resulting in a smoother ride, yet still providing enough lifting effect like a water ski. However, unlike water skis, the waterwheels rotate around an axel, which is mounted on bearings, thus considerably reducing drag and improving efficiency.
