Abstract/Summary

Access to potable water is a global issue that has yet to be adequately solved. In regions with limited access to electricity and ground or surface water, it is not always possible to provide clean water requiring external power or extensive infrastructure to implement. This Final Design Report document will outline the background, design and manufacturing plan involved in the development of a passive atmospheric water harvester. This report builds on the earlier Preliminary Design Review and Critical Design Review documents to reflect further research, analysis, comments from reviewers, and detailed design documentation. While a final design was decided on and was in preparation to be built, the COVID-19 pandemic in California altered project progress. While most of this report is based on the originally planned design, it will also provide further detail for manufacturing later for the project sponsor, as well as results from a basic, modified prototype. The basic prototype used to perform proof of concept testing showed positive results, producing up to 0.203 pounds of water produced per 3 pounds of silica used for testing. We expect with the initially planned 30 pounds of silica, the device could produce approximately 2 pounds of water per day.
