Theoretical and Experimental Analysis of an Atmospheric Water Harvesting Solar Powered Device

Adeyanju Anthony Ademola

Two-thirds of the world’s population is experiencing water shortages. The water in the form of vapor and droplets in
the atmosphere, estimated to be about 13 thousand trillion liters (Schneider, 2011), is a natural resource that could
address the global water problem. Although there has been interest in dewing from moist air and fog capture, these
processes require either the frequent presence of 100% relative humidity or a large amount of energy and thus are
not viable solutions for the capture of water from air. Ideally a water harvesting system should operate with a material
that can capture and release water with minimum energy requirements and that is powered by low grade energy
sources.
This study designed, analyzed and tested a semi-open atmospheric water harvesting solar powered device using
atmospheric water vapor membrane technology
