Abstract:

The present disclosure includes apparatus, methods, and systems for power generation. One power generator embodiment includes a shaft; a buoyant assembly slidably coupled to the shaft upon which the buoyant assembly rises and falls, the buoyant assembly configured to be moved in at least a first direction by a fluid on which the assembly is buoyant; wherein a first generator is arranged to create electric energy from interaction of a conductor with a number of magnetic elements on the buoyant assembly, in a manner to produce electricity, as the buoyant assembly moves on the shaft when falling in a second direction due to a gravitational force; and a slowing mechanism arranged to slow the movement of the buoyant assembly in order to separate an outer surface of the buoyant assembly from the fluid along at least a portion of the first or second direction.
