| Abstract | Recently, significant rise of demand for space missions is reported worldwide, especially for goals like resource development and extensive scientific research on the moon for manned environment. To found manned habitats on the moon, extreme temperature gap which ranges from 90 K to 390 K should be dealt successfully, leaving difficulties on building design. However, the extreme contrast of the temperature not only poses challenges but also offers an opportunity for energy generation, with the thermoelectric generators(TEG). TEG can be implemented on the case with the wide range of temperature and can use that contrast as a passive power source. Moreover, TEG have no moving parts, making them reliable in the harsh environment, including issues related to lunar dust. Therefore, this paper aims to assess the suitability of TEG in lunar environment, by measuring their characteristics under lunar environmental conditions. After simple concepts of TEG is introduced, the experiment is conducted with the chamber, which simulated extreme vacuum and low temperature. The results showed that TEG efficiency increases with greater temperature gradients, especially in cooling conditions. The result means the TEG have the potential for passive energy harvesting on the Moon. Future research should be conducted on system design and further experiments to advance passive energy harvesting on the Moon. |
