A small electrical appliance, such as an electrical wet shaver or electrical toothbrush, is driven by the energy generated by the temperature differential in its environment of use. The heat of the hot water used when wet shaving with an electrical wet shaver, versus the relatively lower temperature of the handle, which is in an environment at room temperature, causes a thermoelectric generator operating as a Peltier cooler using the Seebeck mode, to generate enough electrical power to drive the motor of the appliance and/or to recharge a rechargeable electrical battery, which may also be present.
