Solar-Powered Device Turns Seawater Into Drinking Water

Some say that the next world war could happen because of water crisis. Ever thought about it?

An Italian designer, Gabriele Diamanti, has developed a solar powered water purification device that can convert sea water into safe drinking water. The device is named Eliodomestico.

How Does It Work?

It works on the process of distillation, similar to that of an upside-down coffee machine. It is essentially a solar still that boils the seawater or polluted water to produce steam. The steam forces the nozzle at the top to open and condenses at the lid to deliver clean water. It is then collected at the base of the device. Five litres of water can be purified each day in the sun. The device is made out of terracotta, anodized zinc and recycled plastic. It doesn’t require electricity and has no filters, hence maintenance is minimal. The design is open source and was named as one of 12 finalists in the Prix Émile Hermès 2011 competition.

This can be a boon for places where water is brackish and there is no electricity. Unlike other solar stills, this is a more efficient process and the overall cost would be around half of other such devices.
