Abstract
A power-generating system includes a heat source which is able to produce temporal temperature variation; a first device which is able to produce temporal temperature variation based on the temperature change of the heat source and in which polarization occurs; a second device for taking out a net generating power from the first device; a temperature sensor that detects the temperature of the first device; a voltage application device that applies a voltage to the first device; and a control unit for activating the voltage application device on detecting an increase in temperature of the first device and for stopping the voltage application device on detecting a decrease in temperature of the first device by the temperature sensor.
