There can be little doubt that supplying clean water to populations experiencing water shortages is a vital public health imperative. Imagine then, a household appliance that extracts all the water a family needs out of thin air, using only solar power.
This article describes the design and testing of a device utilizing a porous metal-organic framework (MOF) that captures water from the atmosphere using only heat from sunlight. The authors’ prototype device was able to extract over 2 liters of water from ambient air over a 12 hour period using one kilogram of a MOF. Additionally, the system operates under conditions as low as 20-30 percent relative humidity, a moisture level common in desert areas.
This is a truly remarkable innovation that could save innumerable lives, especially when droughts develop in remote or desert areas. Read more here and here.
