Abstract
Scarcity of easily attained clean drinking water is a threat to a growing global human population. New discoveries in materials science are yielding potential opportunities to harvest freshwater from our atmosphere in even arid climates of low relative humidity. The advent of these new materials provides an opportunity to partially address this global challenge. This project reviews the current crisis facing the world’s population and the state of technology related to atmospheric water harvesting (AWH) and the potential it embodies to democratize access to safe drinking water. This review concludes with a conceptual proposal to develop a device that leverages basic physical properties in a simple, portable form that could efficiently harvest drinking water from air using the power of the sun and gravity. The goal is to design a device that could be built at low cost with no electrical componentry which relies on simple and repairable gearing mechanisms that are easy to maintain. The device should provide continuous harvesting of water during daylight hours in temperate and arid climates sufficient to sustain at least one person or a household per day. Ideally the device could be produced locally with minimal components that rely on the global supply chain.
