MIT researchers designed a device that quickly recovers drinking water from an atmospheric water harvesting material. The system uses ultrasonic waves to shake the water out of the material, recovering water in minutes.
It’s not the condensing that takes energy, it’s the thermal release of the water from the desiccant that takes energy. Here’s the real paper with all the details. Avoiding thermal release in favor of mechanical release of water from the desiccant bypasses a good portion of the energy required.
Cool, but the fact remains that you can’t get a useful amount to water from dry air, and in a humid climate there are other sources of water that is cheaper and easier to exploit.
