Clean water is a vital building block for life, but what do you do if you live in an area where clean water is hard to come by? Promising efforts from all over the world have begun to create devices which produce water straight from the air around them in what are known as atmospheric water generators. These devices rely on the relative humidity in the atmosphere around a certain area to convert air into usable, drinkable water. This is discussed in further detail in the report. Several design considerations led to a thermoelectric module driven system which would utilise the Peltier effect and forced induction to force air across a cooled heat sink which induces condensation of the air, thus allowing water to be collected. Results concluded that environmental conditions such as humidity level and air flow, as well as power requirements, are important factors in water generation. Limitations arise based on the humidity in the air and access to an efficient power source. This thesis paper provides a design and prototype for a portable device capable of atmospheric water generation.
