ABSTRACT:
Electric power is generated from a non-uniformly operating energy source such as wind or water waves by driving hydraulic pump means by a wind wheel or a bobbing float. The pump feeds hydraulic medium into a cylinder to raise a piston loaded by a weight. When the weight rises above a predetermined level, the medium is fed under its constant pressure to drive an hydraulic motor connected to an induction generator. Because the generator is driven at constant power (though intermittently) it can be connected to the public mains supply, eliminating the need to store power, without sophisticated interface arrangements. A second generator connected to a resistive space or water heating load can be cut in at higher energy levels. The hydraulic pump can be arranged to extract power from the source in the most efficient way.
