Abstract
A system in accordance with the invention includes a thermo-electric device that is physically proximate with a thermal energy source, where, in operation, the thermo-electric device generates a voltage potential. The system further includes a power conversion circuit connected with the thermo-electric device, to modify the generated voltage potential. Also included in the system is a controller circuit connected with the power conversion circuit, where the thermo-electric device powers the controller circuit via the power conversion circuit. The system additionally includes a valve-control circuit connected with the controller circuit and the power conversion circuit, such that the thermo-electric device powers the valve control circuit, at least in part, via the power conversion circuit. The system also includes one or more sensing devices connected with the controller circuit.
