1. A thermoelectric power generation system comprising:

  • a thermoelectric generator having thermoelectrics with at least one cold side and at least one hot side, the TE generator configured to generate electrical power when a temperature gradient is present between the at least one cold side and the at least one hot side;

    a first working fluid in thermal communication with at least one heat source;

    a second working fluid flowing in an intermediate heat transfer loop and separate from the first working fluid, the second working fluid in thermal communication with the at least one hot side, and in thermal communication with the first working fluid such that heat is transferred from the first working fluid to the second working fluid and heat is positively transferred from the second working fluid to the at least one hot side; and

    a flow control system adapted to control the flow of the second working fluid in response to changes in heat originating from the at least one heat source.
