Eliodomestico Solar Still

Fresh water is taken from the still at the end of the day.

The still heats either salty or dirty water in the upper chamber, steam is created, and fresh water condenses and collects in the lower chamber.

The Eliodomestico Solar Still was designed by Gabriele Diamanti, who was inspired by his world travels to try to help with global water scarcity. His solution is an open source water still made primarily of pottery.

It functions by filling the black boiler with salty sea water in the morning, then tightening the cap. As the temperature and pressure grows, steam is forced downwards through a connection pipe and collects in the lid, which acts as a condenser, turning the steam into fresh water. Potentially, the still will convert five liters of water daily. Once Diamanti established the fundamentals were sound, he experimented with a series of concepts for the aesthetic of the object. “My goal was to design something friendly and recognizable for the users,” he explains. “The process developed quite naturally to determine the current shape; every detail is there for a reason, so the form, as well as production techniques, represent a compromise between technical and traditional.”

The project won a Core77 Design Award for Social Impact; already, Diamanti has received international feedback, and hopes to see locals adapt and modify the design to take advantage of their own readily available materials and native environments. “The idea is that instructions for the project can be delivered to craftsmen” with the help of NGOs, he says, then a micro-credit program could be established to finance small-scale start-ups specializing in production.
