Portable Atmospheric Water Condenser

There are 844 million people in the world living without access to safe water, and 40% of the world’s population is affected by water scarcity. As the shortage of clean water is rising, it is crucial to start developing ways in which water can be more accessible. One possibility for obtaining water in developing countries is through the atmosphere which contains large amounts of water vapor. This water vapor can be converted back into liquid water by subcooling it to temperatures that are below the dew point. The goal of this project is to create a device which can efficiently condense the water found in our atmosphere. The design needs to be as light, portable, and as cost efficient as possible so it can be easily provided to countries in need. We created a design which incorporates thermoelectric cooling and has components strategically placed within a housing for the most efficient rate of water collection. It is powered using batteries which can be recharged, and the device can be used frequently. The design is fairly small and mold injectable, making it both portable and cost efficient. The housing includes a funnel that allows a water bottle to be placed below the device, and water can be easily collected. With various analyses using ANSYS and tests conducted using humidity chambers in the lab, our device has been tested for its capability to produce water under certain climate conditions that are found in developing countries. With few modifications, this design can help in making clean drinking water more accessible in high impact areas and can provide extensive research and data for future innovation.
