MIT's water harvester works in extreme climate without power or filters
There are plenty of ways to suck water out of the air, whether you need a little or a lot. Massachusetts Institute of Technology (MIT) researchers may have just hit upon one of the best ways to do it, with a device that doesn't need power, or even a filter, to deliver drinking water.
Massachusetts Institute of Technology (MIT) researchers may have just hit upon one of the best ways to do it, with a device that doesn't need power, or even a filter, to deliver drinking water. The group tested its window-sized device in California's arid Death Valley, where it produced between 1.9 and 5.46 fl oz (57 and 161.5 ml) of drinking water per day across a range of humidities. Now, those quantities aren't going to go a long way towards quenching anyone's thirst – so the team believes an array of these vertically hydrogel panels could be deployed in water-scarce regions to deliver larger amounts that could support an entire household.
