Powering unmanned flight using thermoelectric power generation from gas fuel combustion

This project introduces the use of thermoelectric power generation via thermoelectric generators (TEGs) to enhance the fueling system of unmanned aerial vehicles (UAVs), improving flight range and stability. TEGs convert heat directly from fuel combustion into electricity, offering a simpler, more reliable alternative to traditional internal combustion or turbine engines. The prototype uses 12 small TEGs to generate electric power via a temperature gradient, with the heat from combustion and cool air maintaining the gradient. In testing, the TEGs produced the output power under a 46°C temperature gradient, demonstrating potential for UAV power systems.
