Eliodomestico is a solar-powered water filter that can be made from simple and readily available materials and is capable of purifying 5 liters of water each day. Developed by Italian designer Gabriele Diamanti, the water filter is essentially a solar still that boils water and separates it from other elements and delivers clean and pure drinking water. Made from terracotta, anodized zinc, and recycled plastic, Eliodomestico operates without filters or electricity, and requires minimal maintenance.
The solar-powered filter can function without fuel, electricity, filters, and it requires no maintenance. These devices can also be built anywhere from readily available materials – anyone who can throw a pot can handcraft the main elements necessary for the water filter. Diamanti estimates that a normal solar still costs around $100 dollars and only produces about 3 liters a day, while his Eliodomestico could be made for $50 and produce 5 liters.
