Window-sized device taps the air for safe drinking water without electricity

MIT engineers developed an atmospheric water harvester that captures water vapor and produces safe drinking water across a range of relative humidities, including dry desert air.

The system runs entirely on its own, without a power source, unlike other designs that require batteries, solar panels, or electricity from the grid.

“This is just a proof-of-concept design, and there are a lot of things we can optimize,”
