Working Principle

The Thermo-Magnetic Motor of Swiss Blue Energy AG converts low-temperature heat between 20°C to 80°C into usable electricity. A percentage of the thermal energy stored in the temperature difference (ΔT) of two water flows is utilized for electricity production. The minimum temperature difference should be 20K.

Curie Effect and Magneto-Caloric Material

The Curie point defines the temperature, where a reversible phase change of magnetic properties of magneto-caloric materials occurs. The magneto-caloric material behaves paramagnetic above its Curie point (i.e. behavior in a magnetic field comparable to plastics) and ferromagnetic below its Curie point (i.e. behavior in a magnetic field comparable to iron). This behavior is named Curie Effect.

Energy Conversion and Fast Thermal Switch

At a temperature below the Curie point the magneto-caloric material is attracted by the magnetic field of a permanent magnet (ferromagnetic properties). With a temperature above the Curie point, the magneto-caloric material passes the magnetic field of a permanent magnet unhindered (paramagnetic properties). By a fast change in temperature above and below the Curie point of the magneto-caloric material (Fast Thermal Switch) combined with an accurate placement of permanent magnets, a continuous rotation of the rotor is achieved. This mechanical energy is afterwards converted in electricity.

Energy Balance

The Thermo-Magnetic Motor (TMM) converts a percentage of the thermal energy stored in the temperature difference (ΔT) between two water streams into usable zero-emission electricity. This is achieved by a very fast and continuous heating and cooling of a magneto-caloric material around its Curie point and the application of permanent magnets.
