Water harvester makes it easy to quench your thirst in the desert

In 2017, chemists demonstrated that a new MOF design could rapidly adsorb water from even dry air, allowing it to be condensed and collected for drinking. A second-generation MOF can now cycle through adsorption and desorption in 20 minutes, allowing continuous collection of more than a liter per day per kilogram of MOF using solar power. The new MOF is the basis of a planned microwave-sized device that delivers 7-10 liters per day.
