A Simple, Elegant Invention That Draws Water From Air

When Italian designer Arturo Vittori and Swiss architect Andreas Vogler
first visited Ethiopia in 2012, they were shocked to see women and children
forced to walk miles for water.
Only <http://water.org/country/ethiopia> 34 percent of Ethiopians have
access to a reliable water supply. Some travel up to six hours a day to
fetch some or, worse, resorts to using stagnant ponds contaminated by human
waste, resulting in the spread of disease.
Worldwide, a whopping 768 million people - two and a half times the U.S.
population - don't have access to
<http://www.un.org/apps/news/story.asp?NewsID=47409#.U3-BrK1dXL0> safe
drinking water. So just imagine if we could just pull water out of thin air?
That's what Vittori and Vogler asked once they saw the magnitude of problem
and vowed to take action. Their firm,
<http://www.architectureandvision.com/> Architecture and Vision, has since
come up with WarkaWater, a majestic palm-like structure that may look like
something you'd see in a modern art museum but it's been designed to harvest
water from the air.
WarkaWater, which is named after an Ethiopian fig tree, is composed of a
30-foot bamboo frame containing a fog-harvesting nylon net that can be
easily lowered for repairs and to allow communities to measure the water
level.
Collecting water through condensation is hardly a new technique, but the
creators of WarkaWater say their tree-inspired design is more effective,
maximizing surface and optimizing every angle to produce up to 26 gallons of
drinkable water a day - enough for a

Many Failed Attempts By Aid Groups
Western organizations have been working to provide clean water access in
Africa for decades, so WarkaWater joins a very long list of earlier
attempts. So far, high-tech solutions, like the once-promising Playpump (a
hybrid merry-go-round water pump), have failed, mostly due to high costs and
maintenance issues.
This is where WarkaWater could stand apart - as a lower-tech solution that
is easy to repair and far more affordable than digging wells in the rocky
Ethiopian plateau.
Each water tower costs $550 - a Playpump is $14,000 - and its creators say
the price will drop significantly if they start mass-producing it. The
structure takes three days and six people to install and doesn't call for
any special machinery or scaffolding.
"Once locals have the necessary know-how, they will be able to teach other
villages and communities to build the WarkaWater towers," says Vittori, who
is already working on WarkaWater 2.0, an upgraded version that may include
solar panels and LED bulbs to provide light after dark.
The firm is in the process of raising funds to begin installing towers in
Ethiopia next year. And WarkaWater could also prove useful in other areas,
like deserts, which have the critical feature for collecting condensation: a
dramatic change in temperature between nightfall and daybreak.
This elegant invention may not solve all of the world's water woes, but it
could improve accessibility one drop at a time.
The WarkaWater gathers water from fog and condensation. Named after an
Ethiopian fig tree, it consists of a 30-foot bamboo frame and a nylon net.
It was invented by an Italian firm and three of them are shown here in an
Ethiopian village.
