Atmospheric Water Harvesting System

Abstract

A low-cost, passive atmospheric water harvesting system designed for agricultural and community use. It employs a modular pyramidal frame built from ½" PVC tubing and 3D-printed connectors that support interchangeable shade or HDPE meshes at a 67° inclination, condensing fog and dew and directing the water by gravity to a central funnel and food-grade hose compatible with multiple containers. The design is scalable through standardized PVC lengths and replaceable meshes, and has been validated in laboratory and field tests, reaching about 1.5 L per collection event under favorable conditions.
