Abstract

Abstract An electric power station producing fresh water as a by-product by a dehumidification process, utilizing the kinetic and potential energy of water wind waves common to large bodies of water, comprising a wave energy converter including a reception channel and an automatically adjustable standing wave basin, which augments the inherent potential energy of the waves by converting extant kinetic energy therein into potential energy, a wave energy extraction system comprising a plurality of vertical chambers having open bottom ends located approximately coincident with the theoretical wave nodal line and having upper ends, check valved to admit ambient air as the water level therein descends, and to allow to be discharged therefrom as the water level therein rises, an intake manifold admitting ambient air to the chambers, an exhaust manifold for collecting exhausted air under pressure, a refrigerant coil system for extracting water from the exhausted air, and a power conversion system for utilizing the exhausted air under pressure as the prime mover to create electrical energy. The process occurs at or near ambient temperature, thereby minimizing entropy increase loss in the entire system.
