Sustainable Water Harvesting from the Atmosphere Using Solar-Powered Thermoelectric Modules

Abstract

The purpose of this study was to investigate the possibility of solar-powered thermoelectric elements (Peltier) to harvest water from the atmosphere. An Arduino-controlled model capable of harvesting water from air was designed and used in laboratory experiments. The developed prototype system was analyzed by using a package program using computational fluid dynamics. During the experiments, temperature and humidity data were recorded on a computer. We found that the Peltier used in the system developed temperature and relative humidity differences between the inlet air and outlet air from the system. These differences in temperature and humidity created an environment for harvesting water by condensing the humidity in air. © 2020, HARD Publishing Company. All rights reserved.
