Extracting atmospheric water using peltier effect powered by solar energy with contribution from piezo-materials

Abstract

The progressing world has innumerable problems and the needs of people are increasing rapidly. The shortage of electricity and clean water is one of the most alarming issues of the present times. This paper describes the design of an atmospheric water generator system powered by renewable energy sources. The atmospheric water generator (AWG) consists of a Peltier module associated with two heat sinks and a DC Fan. A solar panel is used to charge up a DC lead-acid battery and to power up the atmospheric water generator; a constant supply to the atmospheric water generator is ensured by the assistance of a charge controller. Alongside, piezoelectric elements that are mounted under a tile, light up a digital voltmeter-ammeter display that shows the load voltage and current. This paper includes a complete process of electricity generation from piezoelectric elements and solar PV panel distinctly. It also incorporates a comparative study of power contributions from the Piezo elements and Solar Panel. Both Hardware and Software design models are considered to optimize the performance of the renewable energy harvesting systems. Moreover, the efficiency of water generation with the Peltier effect is depicted through multiple field test results. Finally, a comparative study between the present work and other contemporary research is established based on the water accumulated from the AWG during the field experiments.
