Make a spinner with four blades out of foil and attach it to the end of a wooden stick. Carefully bring the spinner up to the spout of the boiling kettle. What are you seeing? Which heat engine is your turntable model? Describe the energy transformations that occur when the turntable rotates. Explain your experience by illustrating it with video or photographs.

The model is a steam turbine. The “fuel” energy supplied from the outside is converted into thermal energy of the working fluid and the energy of the supplied working fluid into mechanical energy of rotation of the blades.
