Abstract: A method and device for generating electricity from ocean waves. The device includes at least one magnetostrictive element and one or more electrically conductive coils or circuits. When the magnetostrictive element is deployed in a body of water, the motion of the body of water, including wave motion, causes changes in the strain of the magnetostrictive element. The electrically conductive coil or circuit is within the vicinity of the magnetostrictive element. A corresponding change in magnetic field around the magnetostrictive element generates an electric voltage and/or electric current in the electrically conductive coil or circuit.

Abstract: A method and device for using radial relative displacement between a magnet and coil to generate electricity from fluid motion. The device includes a support structural component, a moveable magnetic structure, a rotating structural component, and bearings. The moveable magnetic structure is coupled to the support structural component. The rotating structural component rotates relative to the support structural component. The bearings are coupled to or disposed with the rotating structural component. The rotation of the rotating structural component results in forces applied by the bearings on the moveable magnetic structure and movement of the moveable magnetic structure.

Abstract: A method and device for using magnetostriction to generate electricity from fluid motion. The device includes a first structural component, an outer housing, and a strain structure. The outer housing substantially circumscribes the first structural component and at least partially defines an annular space between the first structural component and the outer housing. The strain structure is coupled within the annular space between the first structural component and the outer housing. The strain structure experiences a change in physical strain imposed by a bearing in response to a relative movement between the bearing and the strain structure. The strain structure includes a magnetostrictive material to generate a magnetic field in response to the change in the physical strain.

Abstract: A method and device for energy conversion from a moving fluid to electrical energy. The device includes at least one magnetic structure, at least one coil structure, a rotating component, and a rotary to linear motion conversion mechanism. The at least one coil structure includes electrically conductive material. The rotating component rotates relative to a corresponding axis of rotation in response to forces applied by the moving fluid on a structure coupled to the rotating component. The rotary to linear motion conversion mechanism is coupled to the rotating component. Rotation of the rotating component around the corresponding axis of rotation generates a relative linear displacement between the at least one magnetic structure and at least one coil in the at least one coil structure. The relative linear displacement between the at least one magnetic structure and the at least one coil generates electrical energy in the at least one coil structure.
