Conversion of thermal energy into motion

Principle

This experiment shows that a thermo generator can produce mechanical energy with the help of coldness and heat. The thermal tension of a thermo generator depends on the temperature difference across the element.

Task

Can a motor be put into motion with heat or coldness?

In this experiment the thermocouple is connected to a motor. You will try to activate the motor  by placing a mug with hot water or ice cubes on the thermocouple.
