1. A method for supplying conditioned air to a compartment of a vehicle having an electric side comprising components relating to an electric motor for powering the vehicle and a fuel fed side comprising components relating to a fuel fed engine for powering the vehicle, the method comprising:

  • circulating a first fluid in a first circuit in thermal communication with the electric side of the vehicle;

    circulating a second fluid in a second circuit in thermal communication with the fuel fed side of the vehicle;

    transferring thermal energy between at least a first heat transfer surface of at least a first thermoelectric device and at least one of the first circuit and the second circuit;

    transferring thermal energy between at least a second heat transfer surface of the first thermoelectric device and an air stream;

    transferring thermal energy between at least a first heat exchanger disposed in the air stream and the second fluid circuit; and

    selecting between the first circuit and the second circuit to transfer thermal energy between the first heat transfer surface of the first thermoelectric device and the first circuit or the second circuit;

    wherein at least the first circuit, the second circuit, the first thermoelectric device, and the first heat exchanger cooperate to condition the air stream.
