Thermoacoustic thermomagnetic generator

Abstract

The present invention is a thermoacoustic thermomagnetic generator 100 . The generator includes a stator 5 that supports and channels magnetic fields. It further includes a magnetic field generator 2 that magnetically couples to the stator. In addition, the generator includes a magnetic circuit opening and closing member 1 that changes magnetic states in response to changes in temperature where the member couples to the stator to complete a magnetic circuit. Further, the generator includes a thermal insulator 4 that couples to the stator and the magnetic circuit opening and closing member. And, the generator includes a plurality of induction windings 3 that conduct electric current where the induction windings couple to the stator. The periodic opening and closing of the magnetic circuit creates a magnetic field in the stator that induces an alternating electric current in the induction windings which allows the generator to produce electric power.
