Eliodomestico is an open-source eco-distiller, running on solar power, to provide safe drinking water for people in developing countries. It’s a very simple way to produce freshwater, starting from sea or brackish water. The device produces 5 liters daily, through a direct solar-powered distillation process. Eliodomestico works without filters nor electricity, and requires minimal maintenance.

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.

Eliodomestico is part of the series: Smart Designs for Social Good.
