Any device capable of generating a given energy, in particular a given heat energy, may be included in the power source generator 100.

The power source generator 100 includes a thermoelectric element 150. The thermoelectric element 150 may produce electrical energy by using a thermoelectric effect, which is a phenomenon in which current flows when a temperature difference occurs. Electrons of a high temperature object have higher kinetic energy than electrons of a low temperature object, and when two objects are connected, electrons of a high temperature part spread to a low temperature part and generate electricity by using a phenomenon in which a potential difference occurs.
