The solar-powered harvester, constructed in the Massachusetts Institute of Technology (MIT) can harvest liters of water from air everyday, even in desert conditions. All it needs is a minimum humidity of 20% in the air. Electric dehumidifier at homes produce very expensive water.
Currently, the prototype can pull 2.8 liters of water from the air over a 12-hour period, with humidity conditions to be around 20% – 30%.
The system consists of dust-sized MOF crystals compressed between a solar absorber and a condenser plate, placed inside a chamber open to the air. An ambient air diffuses through the porous MOF water molecules preferentially attach to the interior surfaces. Sunlight entering through a window heats up the MOF and drives the bound water toward the condenser. The vapor condenses as liquid water and drops into a collector. (*MOF = Metal organic framework, a special material produced at UC Berkeley)
This is pretty interesting. Just imagine how many villages in developing countries can be helped using this!
These have to implemented more and more
Ikr! Maybe in the coming years ☺️
