Abstract: A method facilitates storing and discharging renewable energy. The method includes applying an electrical potential across a membrane comprising an oxygen ion conducting material during an energy storage cycle, transporting oxygen through the membrane to move oxygen from ambient air to a storage chamber during the energy storage cycle, subsequent to the energy storage cycle, applying an oxygen partial pressure differential across the membrane during an energy discharge cycle, transporting oxygen ions in an opposite direction through the membrane during the energy discharge cycle; and generating an electric current in at least one electrical circuit electrically connected to the membrane during the energy discharge cycle.

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 movable magnetic structure, a rotating structural component, and bearings. The movable 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 movable magnetic structure and movement of the movable magnetic structure.

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 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.
