Abstract: An airframe having an integrated thermoelectric generator and a method thereof for providing electricity in an aircraft. A plurality of thermocouple wires is disposed about an aircraft frame to form a thermopile circuit in which electrical current is generated as a result of a temperature difference observed at a cruising altitude. The temperature difference is created by a hot side, interior to the aircraft frame, and a cold side, exterior to the aircraft frame. The thermopile circuit is formed by a first thermoelectric material and a second thermoelectric material that are selected to produce a desired voltage when exposed to the temperature difference. The electric current is harnessed by a transfer cable and directed to an aircraft electrical system to provide power to the desired devices.
