Solar-powered still turns salty ocean water fresh
Today at Earth Techling:
Without access to fresh, clean drinking water, millions of people around the world must endure compromised health conditions and a poor standard of living. Many, mostly women, are forced to walk long hours to find water supplies, which are often polluted, only to face the backbreaking task of carrying it home. By the year 2025, 2/3 of the world population will lack sufficient fresh water, so this problem is only going to get worse if we don’t find a practical solution
Designer Gabriele Diamanti has spent many years traveling the world, and seen this problem repeated over and over. He decided to use his knowledge of industrial design, renewable energy, and social issues to create a possible solution. What emerged is something Diamanti likes to call a solar still: a device that takes salt or brackish water and creates something drinkable.
“It can deliver very positive outcomes for the local economies, because it’s designed to be produced (and eventually repaired) by local craftsmen, thus generating a market,” writes Diamanti. “Craftsmen from many different places can produce the distiller, using the materials that they already can manage. The production techniques are very sustainable, already present in the developing countries, so there is no need to teach anything to the craftsmen.”
