1. A device, comprising:
a controller implemented in electronic circuitry and configured to cause a pilot light of an intermittent flame-powered pilot combustion system to be intermittently ignited and extinguished;
an igniter configured to create a spark to ignite the pilot light;
a thermal electric power source;
a second power source configured to:
supply power to the controller when the thermal electric power source is not being exposed to a flame of the pilot light; and
a third power source, separate from the second power source, and configured to:
store energy;
supply power from the stored energy to the igniter to create the spark; and
receive charge from the thermal electric power source in response to the thermal electric power source being exposed to the flame of the pilot light
wherein the thermal electric power source is structured to generate power via a thermal electric effect when the thermal electric power source is exposed to the flame of the pilot light, and to provide a source of power for powering the controller and for recharging the third power source when the thermal electric power source is exposed to the flame of the pilot light.
