The broader impact/commercial potential of this I-Corps project is the development of a universal atmospheric water harvesting technology for producing drinking water and water for other uses where water access is limited. Water scarcity has become increasingly severe due to population growth and climate change. According to the World Health Organization, an estimated 785 million people live without access to clean water, and it is recognized that a water shortage is a surging global crisis. There is increasing global interest in solutions that provide safe drinking water without the environmental consequences of increasing reliance on bottled water. The proposed atmospheric water harvesting technology may provide a solution to overcoming the water shortage of almost any water-deficient area lacking liquid water sources. It is envisioned that the proposed technology may be used to provide personal water production equipment as well as scaled to provide household-/facility-based or community-based water supply systems.This I-Corps project is based on the development of atmospheric water harvesting materials and systems that are used to collect and produce water from the air without consuming electricity. The proposed atmospheric harvesting system uses a biomass-based composite that is designed to serve as a sustainable carrier of hygroscopic salts that harvest water from the air under a wide range of humidity and temperature conditions. In addition, the proposed technology uses the heat converted from solar energy directly to facilitate water harvesting without requiring a complex operating system and absorbs water moisture when exposed to air, no matter whether the composite unit is stationary or mobile. The proposed technology provides the potential to expand water availability during shortages, contamination events, and other issues that can interrupt drinking water services.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该I-Corps项目的更广泛的影响/商业潜力是开发一种通用大气收集技术，用于生产饮用水和水，以用于水的其他用途。由于人口增长和气候变化，缺水变得越来越严重。 据世界卫生组织称，估计有7.85亿人无法使用清洁水，并且人们认识到水短缺是一场日益严重的全球危机。 全球对提供安全饮用水的解决方案的兴趣越来越大，而不会增加对瓶装水的依赖的环境后果。 提出的大气收集技术可以提供解决方案，以克服几乎所有缺乏液态水源的缺水区域的缺水。 可以预见的是，所提出的技术可用于提供个人水生产设备，并进行扩展以提供基于家庭/设施的供水系统。这项I-Corps项目基于大气收集材料和系统的开发，这些材料和系统用于从空气中收集和生产水，而无需消耗电力。提出的大气收获系统使用了基于生物质的复合材料，该复合材料旨在用作湿润盐的可持续载体，该盐在广泛的湿度和温度条件下从空气中收集水。 此外，提出的技术使用从太阳能直接转化的热量来促进水收集，而无需复杂的操作系统并在暴露于空气时吸收水分，无论复合单元是固定还是移动的。 拟议的技术提供了在短缺，污染事件以及其他可以中断饮用水服务的问题中扩大水的潜力。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，认为值得通过评估来提供支持。
