Patent ID: 7436082

Claim:
A rocking motion charging device for generating electricity in a rocking device or apparatus, including a marine vessel, comprising: at least three rocking devices, each having a magnet and a coil for moving in relation to one another for generating electricity using Faraday's principle; and a gimbaled member coupled to the at least three rocking devices, the at least three rocking devices being spaced at different points in relation to one another on the gimbaled member, the gimbaled member being responsive to a rocking motion causing at least two different points on the gimbaled member to move in opposing directions along an axis, for moving at least one magnet or coil of at least one rocking device in relation to one another in one direction substantially along the axis, and for also moving at least another magnet or coil of at least another rocking device in relation to one another in an opposite direction substantially along the same axis so as to generate the electricity.
