Device for the direct transformation of heat into electricity

The device is based on the fact that ferromagnetic materials always have a temperature range over which their magnetic permeability varies greatly with temperature. Consider, therefore, a ferromagnetic material 1 (e.g. a set of thin plates) immersed in an external magnetic field obtained by a suitable means such as a coil 5 carrying a direct current. Large variations in the magnetic field over the volume occupied by this material will be obtained if the material is alternately heated and cooled by a suitable thermal system. An example of such a system would send through the material alternate currents of hot gas and air at room temperature respectively entering through inlet valves 6 and 7 and emerging through outlet valves 8 and 9. It is then sufficient to place a circuit (e.g. a coil 3 wound round a cylindrical former 2) in such a position that the above field variations produce variations in the magnetic flux across the circuit. This induces an emf in the circuit, and hence a current if the circuit is complete.
