Italian designer Gabriele Diamanti has developed a simple but very effective solution for the problem of scarcity of clean drinking water. Using the technique of solar still – whereby the power of the sun purifies polluted water – on a small scale, the eliodomestico makes it possible for people living in areas that lack enough drinking water, to make their own.
Simply pour salt water into the black top and let the warmth of the sun do its work. The steam that is produced condenses against the lid of the bottom part of the eliodomestico, resulting in clean drinking water dripping in the basin. The eliodomestico produces up to five litres of clean water per day.
The prototype is made of terracotta, but any other type of material will do so that local craftsmen can make us of materials locally available to them.
