Instead, spurred on by his own extensive
travel and friends' involvement in NGOs, he developed a fascination
with global water scarcity as a graduate student at Milan
Polytechnic in 2005; he recently decided to pursue his interest
again and the result is
Eliodomestico, an open-source
variation on a solar still.
In theory, no more trees would be cut to be used for making charcoal, if everyone switched to using solar ovens. And, while the use of a solar oven is not always feasible, a better understanding of their use can open up many doors and new possibilities.
There are many solar oven designs, but each of them uses the same basic principles. They concentrate sunlight, using mirrors or other types of reflective metal, into their designated cooking areas.
The more concentrated the light, the more potent the concentration will be.
Diamanti's design 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 Gabriele Diamanti established the fundamentals were sound, he experimented with a series of concepts for the aesthetic of the object.
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, or as large plants overseen by qualified personnel that serve entire communities.
The project recently won a Core77 Design Award for Social Impact.
Already, Diamanti has received international feedback, and hopes to see locals adapt and modify the design to take advantage of their own readily available materials and native environments.
