Patent ID: 8093869

Claim:
An apparatus for generating electrical power, comprising: at least one section of magnetically polarizable material, a source of mechanical vibration acoustically coupled to the magnetically polarizable material being capable of producing acoustic excitation within the magnetically polarizable material, at least one source of magneto-motive force coupled to the magnetically polarizable material being capable of producing magnetic polarization of the magnetically polarizable material, one or more electrical conductors encircling the magnetically polarizable material, each comprise a plurality of conductive elements inductively coupled to the magnetically polarizable material wherein each separate inductive element is separated from the next by a distance not less than ⅛ the acoustical wavelength of the lowest-order resonant mode of the acoustic oscillation in the apparatus, for purposes of extracting electrical energy and providing an electrical power output, a physical separation between the source of mechanical vibration and the nearest electrical conductor corresponding to a distance not less than ⅛ the acoustical wavelength of the lowest-order resonant mode of acoustic oscillation in the apparatus; and an electrical load, being in direct electrical communication with the electrical power output, having a nonlinear time-changing resistance, by including semiconductor switching elements for purposes of periodically modulating the current.
