DIY Magic Fan Automatic Temperature Controlled - STEM Discovery Kit

DIY Power Fan: Thermal Energy Experiment – Physics Project Kit

This setup demonstrates a basic application of thermoelectric power generation using a Peltier module to power a DC fan.

Thermoelectric power generation, using devices known as thermoelectric coolers or Peltier modules, relies on the Seebeck Effect. This effect occurs when a temperature gradient is applied across a thermoelectric material, causing a voltage difference to develop between the hot and cold sides.

This voltage difference generates electrical power. Peltier modules contain semiconductor materials that exhibit the Seebeck Effect. They have two sides: a hot side and a cold side. When a temperature difference is maintained between these sides, it induces a flow of electrons, creating voltage across the module. Additionally, in this thermal energy experiment, a heat source is applied to the hot side while the cold side stays cooler. As a result, the module produces voltage that powers the DC fan, making this an excellent physics project for science exhibitions.

Materials

Note: Remember that this setup may not generate a large amount of power, but it serves as an educational and demonstrative science exhibition project to showcase the conversion of temperature difference into electrical energy. Always ensure safety precautions when working with electrical components and heat sources, especially when used by children.

Working Principle

Heat is applied to the metal container, creating a temperature difference across the thermoelectric generator (TEG). The TEG converts this temperature gradient into electricity using the Seebeck Effect. This electricity powers the fan, which begins to spin and demonstrate the transformation of thermal energy into electrical energy. Moreover, the heat sink on the cold side ensures efficient heat dissipation, maintaining the temperature difference for consistent operation.
