Arizona-based startup, Zero Mass Water, has created something called a "hydropanel," which generates drinking water from ambient air, according to a news release by Curbed.

 

The company introduced the Source Rexi Hydropanel at CES. The device can be installed on residential roofs like a solar panel.

Sunlight powers fans inside the panel that pull in humidity from the air. Once inside the panel, air is purified and passed through a spongelike material that concentrates the water vapor and deposits it in a reservoir. The water is mineralized for drinking and ozonated to ensure it's kept clean. You only need to install a tap or connect it to an appliance, such as a refrigerator.

For U.S. customers, a Source array with two hydropanels is expected to cost between $5,500 and $6,500.
