Abstract
Abstract An energy-conversion system is disclosed for converting water surface movement, e.g. wave motion, to useful energy. Buoyant structures are provided defining pairs of opposed surfaces affixed together by pivotal structures with energy means, e.g. bellows, held spaced-apart from the pivot means. In the disclosed embodiment, the bellows are actuated with displacements between the buoyant structures, to develop positive fluid pressures to accomplish various operations. As disclosed, a turbine is driven to motivate an electrical generator for providing electrical power through a conductor to an electrical load.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
80 words
A conversion system for providing useful energy from water surface motion, comprising: a plurality of buoyant means defining pairs of opposed surfaces; a plurality of pivot means fastening said opposed surfaces together, for allowing said surfaces to swing about said pivot means in two dimensions; a plurality of bellows means affixed between said opposed surfaces at locations spaced apart from said pivot means; and energy accumulation means connected to said flexure means for providing useful energy from said flexure means.
Claim 2
Dependent Claim
80 words
A conversion system for providing useful energy from water surface motion, comprising: a plurality of buoyant means defining pairs of opposed surfaces; a plurality of pivot means fastening said opposed surfaces together, for allowing said surfaces to swing about said pivot means in two dimensions; a plurality of bellows means affixed between said opposed surfaces at locations spaced apart from said pivot means; and energy accumulation means connected to said flexure means for providing useful energy from said flexure means.
