Carnot cycle with Peltier cooler

If a current of approximately 10 A is applied to a Peltier cooler, heat transfer occurs. One side cools and one side heats up, depending on the direction of the current. The Peltier cooler can also be operated as a thermocouple, in that it is cooled on one side and heated on the other side. A current of around 1-4 A is generated, which can be used to operate a motor.

Caution: Experiment with LN₂ (eye damage and cold injuries possible)!
Personal protective equipment necessary!
