Chemistry Professor Omar Yaga (Omar Yaghi) from the University of California at Berkeley along with a team of engineers has developed a device for collecting fresh water in arid conditions.
The secret device – in the material that the Professor called ORGANOMETALLIC structure, or MOF. This porous ORGANOMETALLIC system based on zirconium. During cooling, ambient temperature in the night MOF absorbs drops of water, like a sponge. With the increase of temperature after sunrise, the water is released from the power of the crystals deposited on the walls of the box. Therefore, the apparatus collects one hundred grams of water per kg during the cycle.
The invention appeared last year, and all this time, the team tested it in different conditions. Now she’s published a report in the journal Science Advances. The article reports on the new generation of MOF-303, which is based on aluminum, which reduces the production mechanism. Allegedly Omar Yaga, the apparatus 150 times cheaper, but collects two times more moisture in laboratory tests.
He spoke about the invention: “nothing In the world is like. The device operates at ambient temperature using sunlight, and needs no additional energy. With it, you can collect water even in the desert. We have a desire to commercialize it and the launch of several start-UPS.”
