Abstract:
1. A device for generating electricity, the device comprising: a buoyant structure; a heave plate having an asymmetric geometry to facilitate a first level of resistance to movement in an upward direction and a second level of resistance in a downward direction, wherein the heave plate comprises a concave geometry on an upward surface, wherein the first level of resistance is higher than the second level of resistance; at least one load carrying structure that is mechanically coupled to both the buoyant structure and the heave plate, wherein the at least one load carrying structure is configured to taut-moor the heave plate to the buoyant structure; at least one magnetostrictive element wherein the magnetostrictive element is configured to experience force changes applied by the load carrying structure caused by hydrodynamic forces acting on the device.
