Thermo-Magneto-Electric Generator—An Approximate Theoretical Approach

Thermo-magneto-electric-generator can be a very efficient system of heat extraction and electricity production with the help of phase transition property of soft magnets and piezoelectric property of some elastic materials. It works due to oscillation of soft magnet between heat source and heat sink which cause vibration of piezoelectric cantilever. It is better than other heat recovery ventilations because it does not waste the heat but also uses that energy to produce electricity. The main source of potential for oscillation of soft magnet is linear magnetic field produced by hard magnet which in return causes magnetic potential energy in soft magnet. The hard magnet also acts as an unlimited fuel for the system until considerable amount of heat is extracted.
