2012/08/16: Eliodomestico, an open-source variation on a solar still.
It functions by filling the black boiler with salty sea water in the morning, then tightening the cap. As the temperature and pressure grows, steam is forced downwards through a connection pipe and collects in the lid, which acts as a condenser, turning the steam into fresh water. Once Diamanti established the fundamentals were sound, he experimented with a series of concepts for the aesthetic of the object. “My goal was to design something friendly and recognizable for the users,” he explains. “The process developed quite naturally to determine the current shape; every detail is there for a reason, so the form, as well as production techniques, represent a compromise between technical and traditional.” Primary field studies in sub-Saharan Africa revealed the habit of carrying goods on the head–also a common practice in other areas around the world–and this was integrated into Eliodomestico’s plan. And while solar stills aren’t a totally new concept, Diamanti says it’s rare to find them in a domestic context rather than in missions or hospitals
Following my fundraising campaign to buy a solar oven for the village of Ifaty in Madagascar it is my pleasure to announce that I was finally able to deliver not one but 14 solar ovens in two villages (Ifaty and their neighbor Tvinissou)!
