Abstract: In one embodiment, a system is disclosed that includes a thermoelectric generator (TEG) layer that comprises a thermoelectric nanostructure. The system also includes a thermal conductance layer coupling the TEG layer to a catalytic converter and provides heat from an exhaust gas passing through the catalytic converter to the TEG layer. The system additionally includes a cooling layer coupled to the TEG layer opposite the thermal conductance later that provides cooling to the TEG layer.

Abstract: In one embodiment, a system is disclosed that includes a clamp that defines a substantially cylindrical aperture. One or more thermoelectric generator (TEG) layers are coupled to the clamp and receive heat from the clamp. The TEG layers may be formed using thermoelectric nanostructures. One or more heat sinks are also coupled to the one or more TEG layers that provide cooling to the TEG layers.
