This study analyzes and examines the Earth-Air Thermoelectricity Generator (TTEJ), which works with earth temperature and is recommended to be used peculiarly in safety systems, both theoretically and experientially. To examine how TTEJ functions in natural conditions, temperatures at the soil depth and soil surface were equal to the length of the generator, and ΔT temperature differences were measured and modeled throughout four seasons in five different precincts in Ankara. To create the environment to measure and analyze how TTEJ functions in natural conditions, in addition to the standard TEJ theory, to design a thermoelectric earth-air generator or to calculate its parameters, a mathematical model of TTEJ is created by embodying both thermic processes and the thermoelectric generator that functions conveniently for these processes. The thermoelectric parameters such as power P(W) produced by the generator based on T, resistance U(V), and current I(A) are calculated using a custom experiment mechanism built specifically for this research, and the results are compared to theoretical results. The outcome of theoretical and experimental results is congruence. The custom earth-air generator that is created as a model implementation can provide a reliable safety system that is presented and detected. Thus, it is concluded that without any requirements for an electricity cable, it is possible to create a system that can work via TTEJ by generating electricity with the help of the earth's temperature in the event of a property violation or other security-related issue and notifying the security units. Also, it is predicted that, as an innovative and environment-friendly product, TTEJ will be used in various fields of work, especially in military applications.
