The Eliodomestico is a terracotta water filter that uses solar energy to distill 5 liters of water a day without any electricity or fancy parts that need replacement. Developed by Italian designer Gabriele Diamanti, the water filter uses solar energy to boil the unfiltered water from which the steam is condenses on the terra cotta collector proving clean water for drinking and cooking.
Diamanti’s solar powered water filter is designed to provide drinking water for families in developing countries. Eliodomestico is a solar still that operates a bit like an upside-down coffee maker. At the beginning of the day, water is poured into the terracotta chamber.
