Abstract:
1. A device for generating electricity, the device comprising: at least one magnetostrictive element which, when deployed in a body of liquid, the motion of the body of liquid, including wave motion, causes changes in the strain of one or more magnetostrictive elements; and one or more electrically conductive coils or circuits within the vicinity of one or more of the magnetostrictive elements, wherein a surface of the one or more electrically conductive coils or circuits is disposed at a location away from the surface of the one or more magnetostrictive elements to define a gap between the surface of the one or more electrically conductive coils or circuits and the surface of the one or more magnetostrictive elements, wherein a corresponding change in magnetic flux density in the one or more magneto strictive elements generates an electric voltage and/or electric current in the one or more electrically conductive coils or circuits, wherein there is no substantial relative motion between the one or more magnetostrictive elements and the one or more electrically conductive coils or circuits.
