BI-ROTOR GENERATOR FOR EFFICIENT PRODUCTION OF AC ELECTRICITY

摘要

An electrical generator (100) and method of use for producing alternating electrical current at a predetermined frequency, wherein a first rotational element (110) is driven by a force in a first direction at rotational speed determined by the magnitude of the force and a second rotational element (120) is rotated in the same or an opposite direction relative to the first rotational element and is maintained at a predetermined net differential speed relative to the first rotational element. A control unit (130) governs at least one of the direction and the rotational speed of the second rotational element to maintain it at a predetermined net differential speed relative to the first rotational element.
