1. A thermoelectric device, comprising:

  • a stack of thermoelectric modules, each thermoelectric module comprising;

    an inner thermally conductive ring, the inner thermally conductive ring providing a channel for hot gas to pass therethrough;

    an outer thermally conductive ring, an outer surface of the outer thermally conductive ring remaining cooler than the inner thermally conductive ring; and

    a radially-oriented thermopile in connection with the inner thermally conductive ring and the outer thermally conductive ring, wherein the radially-oriented thermopile has alternating regions of thermoelectric material.
