MAGTHERM

Magnetothermal harvesting of low-grade waste heat.

A prototype magnetothermal energy harvester, complete with coils, magnets and fluid connectors

About the project

Low temperature waste heat is a tremendous source of potential energy, especially as low temperature waste heat (< 200 C) from industrial processes. In this project, we will research using a magnetothermal harvester to turn this waste heat into electricity. A thermomagnetic energy harvester utilizes that the magnetization of a material changes with temperature. This can be used to guide magnetic flux through different sets of coils, by changing the temperature of the magnetic material using waste heat. Using modeling, we will design a novel thermomagnetic harvester which we will subsequently test under industrially relevant temperatures in the lab.
