<p>The earth consists mainly of water and water exists on the earth's surface, in aquifers in the soil as groundwater, and in the atmosphere as water vapour. However, of all the water on earth, only less than 3 percent is fresh water. Due to factors such as climate changes, environmental pollution, as well as population growth, the available amount of fresh water sources is dwindling rapidly. In addition, there are many problems associated with provision of potable water using existing techniques. One way to overcome the aforementioned problems is to extract water from the atmosphere. However, hardware costs of current commercial systems are relatively high and they are not efficient in terms of performance. An embodiment of the invention provides a system and a method for obtaining potable water by extracting atmospheric water.</p> |
