Desalinization with Solar Energy


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. The design is available as an open-source project for anyone who wants to make one and is licensed under a CC Attribution-NonCommercial-ShareAlike 2.0 Generic License.

About Heretic

I design video games for a living, write fiction, political theory and poetry for personal amusement, and train regularly in Western European 16th century swordwork. On frequent occasion I have been known to hunt for and explore abandoned graveyards, train tunnels and other interesting places wherever I may find them, but there is absolutely no truth to the rumor that I am preparing to set off a zombie apocalypse. Nothing that will stand up in court, at least. I use paranthesis with distressing frequency, have a deep passion for history, anthropology and sociological theory, and really, really, really hate mayonnaise. But I wash my hands after the writing. Promise.
