Outline of Final Research Achievements

In this research, an innovative power generation system from a low temperature heat has been proposed. In the proposed system, magnetic phase transition is integrated with Faraday's law of induction, electric power is generated without any additional energy conversion, leading to achieving efficient power generation. Magnetic phase transition is a famous phenomenon that a paramagnetic material absorbs low temperature (< Curie temperature) heat and isothermally transforms to a ferromagnetic material at the Curie temperature. Furthermore, the power generation performance of the proposed system has been thermodynamically evaluated by experiments and simulations.
