A power generation system includes: a heat source having a temperature being changed over time; a flow passage through which a heat medium heated by the heat source passes; a power generation device including a power generation element and a first electrode, the power generation element being electrically polarized by temperature change thereof depending on temperature change of the heat medium, the first electrode extracting electric power from the power generation element; a temperature detection device being disposed on an upstream side relative to the power generation device in the flow passage and detecting the temperature of the heat medium; a voltage application device that applies voltage to the power generation element; and a control device that activates the voltage application device when the temperature increase of the heat medium has been detected and deactivates the voltage application unit when the temperature decrease of the heat medium has been detected.

Power generation system

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.

Pyroelectric power-generating system

A power-generating system includes a heat source which is able to produce temporal temperature variation, a first device in which polarization occurs based on the temperature change of the heat source, and a second device for taking out a net generating power from the first device, wherein 80% or higher of the total surface area of the first device is heated and/or cooled with the heat source.
