Solar-Powered Well Achieves Water Harvesting In Deserts

By Brian Spaen

In places like the Sahara Desert, rainfall comes at a premium every year. That doesn’t mean water is not existent in the atmosphere. One Dutch company has been able to figure out how to extract the humidity in the air when it cools off and created a harvesting water well, creating a useable resource in a surprising area.

SunGlacier has created the Desert Twins, a solar-powered water making prototype. It consists of an energy unit that is controlled by solar panels and a collection of metal plates that cool down enough to attract moisture in the air. This water would trickle down the plates and be collected in a well.

Ap Verheggen, a founder of SunGlacier, explained how the machine can pick up water in dry climates in an article on Dezeen. “It's mostly because of the high temperatures that it doesn't rain. The relative humidity is low, but the absolute humidity can be very high."
