The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project is to provide a low-cost, low-energy, off-grid system to obtain freshwater. Water security has been considered the top global risk, as a 40% shortfall is expected between forecasted demand and the available supply of water by 2030. Energy-intensive processing and insufficient clean water productivity of current technologies have become bottlenecks for cost-effective desalination water supply. The renewable energy-driven water utility market is growing, with key stakeholders in developed nations including agriculture and municipal water utility providers. The solar-driven water desalination system in this project is particularly suited for individual installations, underserved populations, and disaster scenarios, all of which are underserved by current desalination techniques. This project advances a process to convert seawater and other brackish water sources into freshwater via a versatile, environmentally friendly, and economically viable desalination system to alleviate water scarcity.The proposed project identifies a reliable, robust, and cost-effective solution for a solar-driven water desalination and treatment system. The project will optimize the advanced thermal and mechanical properties of a scaled Cu/CuO foam-based all-in-one solar evaporator, investigate a cost-effective strategy for efficient water desalination, and integrate a solar energy system with water desalination system by supplying the preheated sea or brackish water through existing solar-related infrastructures. A novel design of a planar interconnected open-pore foam-based evaporator will be demonstrated. The spatial extension of a planar structure is featured with an addition of a third vertical dimension to improve the evaporation performance. When compared to a similar interfacial structure, no extra photothermal materials are required for this design, and the simple structure is favorable for large-scale applications. The goal of this project is to develop a highly-efficient (4.5 kg/m2 h), cost-effective ( $40/m2) desalination system for freshwater supply driven by direct solar irradiation, enabled by novel functional materials and structures.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.

这种创新合作伙伴关系的更广泛的影响/商业潜力 - 技术翻译（PFI-TT）项目是提供低成本，低能量，离网系统来获得淡水。水安全已被认为是全球最大的风险，因为预计需求和到2030年的水供应之间有40％的差距。能源密集型加工和当前技术的清洁水生产力不足已成为具有成本效益的淡化供水的瓶颈。可再生能源驱动的水电市场正在增长，在包括农业和市政水电提供商在内的发达国家的主要利益相关者。该项目中太阳能驱动的水脱盐系统特别适合单个装置，服务不足的人群和灾难场景，所有这些都因当前的脱盐技术而乏味。该项目通过一种多功能，环保且经济上可行的淡化系统将海水和其他咸水源转化为淡水的过程，以减轻水的稀缺性。拟议的项目可以确定可靠，稳健且具有成本效益的解决方案，以实现一种天气驱动的水脱水和处理系统。该项目将优化基于Cu/Cuo泡沫的缩放的高级和机械性能，基于基于的CU/CUO泡沫的多合一太阳能蒸发器，研究一种具有成本效益的有效水脱盐的策略，并通过现有的太阳能通过现有的基础架构来提供预先修饰的海洋或咸面水，将太阳能系统与水脱水系统相结合。将展示一种平面相互连接的开放式泡沫蒸发器的新型设计。平面结构的空间扩展具有添加第三个垂直维度以提高蒸发性能。与类似的界面结构相比，此设计不需要额外的光热材料，并且简单结构有利于大规模应用。 The goal of this project is to develop a highly-efficient (4.5 kg/m2 h), cost-effective ( $40/m2) desalination system for freshwater supply driven by direct solar irradiation, enabled by novel functional materials and structures.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.
