Title:

POWER GENERATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2015/076351

Kind Code:

A1

Abstract:

A disclosed power generation system has a heat source having a temperature that rises and falls with the passage of time, a flow path through which a heating medium that is heated by the heat source flows, a power generation device having a power generation element that undergoes dielectric polarization as a result of the rise and fall of the temperature thereof caused by the temperature variation of the heating medium and comprises a dielectric that has a Curie temperature and a first electrode for extracting power from the power generation element, a temperature detection device that is disposed upstream from the power generation device in the flow path and detects the temperature of the heating medium that flows through the flow path, a voltage application device for applying voltage to the power generation element, and a control means for operating the voltage application device when a rise in the temperature of the heating medium is detected by the temperature detection device and stopping the voltage application device when a drop in the temperature of the heating medium is detected by the temperature detection device. The temperature detection device has a temperature detection element that undergoes dielectric polarization as a result of the rise and fall with the passage of time of the temperature thereof caused by the temperature variation of the heating medium and comprises a dielectric that has a Curie temperature that is equal to or greater than a temperature that is 50°C lower than the Curie temperature of the power generation element and a second electrode for detecting electromotive force from the temperature detection element.
