In this system, thermal energy from the flames of the fire transfer energy to the kettle causing the liquid to become steam. The energy of the steam spins the turbine (mechanical energy) which generates electrical energy that is used to operate the fan. The moving electric motor and the spinning fan blades are a form of kinetic energy. After running for a while, the fan becomes hot to the touch, and every so often releases thermal energy into the air.
