“…If the added complexity and cost of nuclear power is prohibitive, the power subsystem could be supplemented with rechargeable batteries and solar panels left at the surface with an aftbody. Geothermal power production from diurnal surface temperature changes is also possible [28].…”

“…Based on their observations they estimated a peak power of 0.4 mW. A similar study that combined a thermal guide reaching 20 cm into the ground amd a 17.64 cm 2 sink with a TEG reports a peak power of 50 µW [25]. A convection dominated tunnel wall scenario was modeled and evaluated in [26].…”

We introduce an energy harvesting system capable of converting bipolar thermal gradients to electrical energy. An active rectification circuit, electrical impedance matching and commodity thermoelectric generators (TEGs) are used to efficiently extract energy from very small temperature gradients found at the natural ground-to-air boundary. The full harvesting system is modeled in detail from thermal radiation to the electrical load. This end-toend model enables system dimensioning to meet specific application requirements. A multi-year deployment of the harvesting system supplying a wireless sensor network (WSN) for environment monitoring demonstrates the applicability of this system in a real application. The case study confirms self-sustainable operation of an application with a 550 µW power footprint. With a maximum harvested power of up to 27.2 mW during the day and 6.3 mW during the night, a significant improvement in both average and maximum harvested power is demonstrated compared to the state-of-the-art.

“…TEG is not the most efficient of generators, but it is usable in such conditions where other sources cannot be used. For example, it is used in generators for space applications [1][2][3] or as an autonomous power source in ocean depths [4]. The range of sources of thermal energy is very wide, such as radioisotopes [5], [3], and [6], fuel combustion systems [7], boilers [8] and [9], solar energy [10][11][12], etc.…”
