The principle of electricity generation based on the phenomenon of shape memory effect in functional alloys

Camital develops reactive forces of hundreds of MPa and is the simplest "transformer" of thermal energy into mechanical energy.

Functional alloys with the shape memory effect open up the possibility of creating power generation systems based on secondary, low-temperature heat. For example, water cooling channels at thermal and nuclear power plants, exhaust ventilation air, etc. On the demonstration bench, the motor is a functional alloy wire (0.4 mm in diameter). The lower part of the smaller pulley is immersed in a bath of warm water (40...50 C); in this part of the pulley, the wire restores the shape of a straight line under the influence of water heat and generates torque. The wire is in mechanical contact with the generator pulley, which generates electricity and powers the LEDs.
