TL;DR: In this article, a power generator is provided having one or more reservoirs, each reservoir has an inlet and an outlet, and a float is disposed in each reservoir and a shaft is connected to each float.
Abstract: A power generator is provided having one or more reservoirs. Each reservoir has an inlet and an outlet. A float is disposed in each reservoir. A shaft is connected to each float. Controls are provided for actuating each inlets and outlet to cause water to flow into and out of each reservoir via its corresponding inlet and outlet, respectively. As a result, the flowing water moves each float in a vertically oscillating manner to rotate the shaft at an output a rate suitable to generate usable power. Also provided are a method for generating electricity and an energy converter that converts vertical float movement into rotational energy.

TL;DR: In this paper, a power generating system and device using the gravity and the buoyancy is provided to enable the water to be repeatedly used to generate electric energy using gravity and buoyancy without the further adding of any energy source.
Abstract: PURPOSE: Power generating system and device using the gravity and the buoyancy is provided to enable the water to be repeatedly used to generate electric energy using gravity and buoyancy without the further adding of any energy source. CONSTITUTION: For power generating system and device using the gravity and the buoyancy, weights(3), which move up and down according to the water level change, are respectively installed in first and second water tanks(1,2). The water is supplied from the first water tank to the second water tank through a valve(7). If the two water tanks have the same water level, the valve is closed and the water is supplied to the second water tank to a desired water level using a pump(8). A stopper(6) keeps the weight, which raised by buoyancy, under control. If the valve is re-opened, the water is discharged to the first water tank and thus the two water tanks have the same water level, the valve is closed.
