Using Solar Energy To Turn Ocean Water into Drinking Water


“Projects ‘for the 90%’ mostly fall somewhere between two extremes: charity and business,” designer Gabriele Diamanti tells Co.Design. “Neither was my inspiration!” 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.
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, or as large plants overseen by qualified personnel that serve entire communities. “I tried to make something for a real household that could be operated directly by the families,” he says.
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. “The idea is that instructions for the project can be delivered to craftsmen” with the help of NGOs, he says, then a micro-credit program could be established to finance small-scale start-ups specializing in production. “So the NGO is the spark, micro-credit is the fuse, the local craftsmen are the bomb!”

How to Make a Water Distiller That Makes Dirty Water Drinkable With Supplies you Already Have


Image: YouTube screen shot
How cool is this, a very simple water distiller that will turn dirty or salty water into fresh, clean, drinkable water with supplies you most likely already have at home. In the video posted below is an example of a small scale system made only using a plastic bowl, a cup, plastic wrap, a rubber band and a rock or weight.

This simple technique can be expanded to be larger to clean much more water if needed. Take this info and keep it in mind, you may need it one day if the water grid goes down or becomes contaminated. This is also a good idea when camping or out in the wilderness to lighten your pack weight.

This mini-distiller is able to remove bacteria, pollutants, salt, fluoride and 99% of other contaminants in your water. The video below shows you how to make this simple yet effective distiller.
