Summary:A power generating system comprising a heat exchanger comprising an inlet, an outlet and a conduit extending along a length of the heat exchanger between the inlet and the outlet, and a plurality of thermally conductive fins provided within the conduit, a packing fraction of the fins increasing from a first packing fraction proximate the inlet to a second packing fraction proximate the outlet; and a plurality of thermoelectric power generators positioned along the length of the heat exchanger, each thermoelectric power generator comprising a hot side, a cold side and a thermoelectric element extending there between, wherein the hot sides of the thermoelectric power generators are in thermal contact with the plurality of fins such that the temperature of each hot side is substantially equal along the length of the heat exchanger.
