This Device Turns Saltwater Into
Drinking Water Using The Direct Sunlight, Know About It
With water scarcity plaguing prime regions in India this summer,
there is an urgent need to find an affordable solution. One
possible alternative that can substitute water sources during the
scorching summers in India is Gabrielle Diamanti’s solar powered
saline water purifier.
The simple effective device is a personal desalination still that
can be designed with expenditure falling under fifty dollars. The
‘Eliodomestico’ work like an upside down coffee percolator and has
a simple design that can be achieved with widely available
The desalination takes place in two ceramic pieces that sit one
atop the other. In the top piece is a black container where the
saline water is poured. The sun heats the container, converting
water into steam. As the pressure of the steam builds in the top
container, it is forced down a tube into the lower ceramic piece
where it condenses and collects in the basin of the container.
The remarkable utility of this device is defined by its capacity
to collect and purify about five litres of water per day. The
container is designed to be transported on the head- a common
practice of water collection in many rural regions in India. This
device is half the price of a normal solar still and provides two
litres of more freshwater than the normal still.
No fuel, no electricity. and no maintenance make it ideal for
usage by people from all walks of life. The design is available as
an open-source project for anyone who wants to make one and is

This device can be built from readily available materials
The design was a finalist at Prix Emile Hermes competition 201 and
also received a special mention at the Well-Tech Award 2012. It
was also the pro winner of the Core 77 Design Awards 2012 in the
social impact category.
As the journalist Jay Syrmopoulos of The Free Thought Project puts
it, this revolutionary ceramic solar-powered still has the ability
to combat one of the greatest threats to human life in the
developing world, that is, water scarcity.
