Abstract:
1. A power generator, comprising: a) a harborage with a vessel hull therein; b) a supply reservoir larger than the harborage, the supply reservoir having a valved inlet subject to fluctuating water levels of a water body, the reservoir communicating with the harborage through a reservoir valve; c) a drainage area larger than the harborage, the drainage area having a valved outlet subject to fluctuating water levels of the water body, the drainage area communicating with the harborage through a drainage valve; d) the vessel hull capable of rising and falling in the harborage as a level of water in the harborage changes independently of the water level of the water body due to the reservoir supplying water to the harborage through the reservoir valve and the drainage area draining water from the harborage by way of the drainage valve; e) a linear-to-rotary converter, at least one part of which is coupled between the hull and a fixed object, the converter converting the vertical movement of the hull into rotational movement.
