TECHNOLOGY: Drawing water from the air (Wednesday, December 23,
2009)
Evan Lehmann, E&E reporter
LEEUWARDEN, Netherlands -- Answers to climate problems can rarely be pulled from thin air.
But researchers here think they've done just that. A wind turbine the height of a house can suck the
water out of air, they say, describing a process that could help quench the thirst for an increasingly
limited commodity.
"There's a lot of water in the air," said Hans van der Vliet, an engineer designing the turbine, called
the Dutch Rainmaker. "And nobody is using it."

A huge number of people live without enough water
to drink, grow food, refresh livestock and avoid
disputes. The World Bank estimates that 1.1 billion
people worldwide lack access to safe drinking water. Most of them are in poorer countries where
depleted reservoirs are refilled inadequately because of lagging infrastructure.
Warming temperatures, prolonged droughts and a host of other factors, like rapid population
growth, will likely sharpen the risks related to the shortage of clean water.
"By 2035, it is projected that 3 billion people will be living in conditions of severe water stress," the
bank warns. Waning health and rising hunger are likely effects. So are mass migration and war, the
bank adds, pointing to the rising "risk of conflict over these scarce resources."
It could even cause unstable countries to collapse, warns Steven Solomon, whose book, "Water:
The Epic Struggle for Wealth, Power and Civilization," will hit stores on Jan. 5.
"Water is the method by which climate change expresses itself. And the results are terrible," he
said, pointing to melting glaciers, changing river flows and deadly droughts. "Basically we need a
revolution in the way that existing water technologies are used."
Wind, a heat pump and a tank
The test turbine in the Netherlands, where windmills have sucked water out of the soaked soil for
centuries, could be used to hydrate thirsty people in Africa, irrigate fields in California and provide
drinking water for soldiers in remote outposts, "no matter how long they stay," the company's Web
site says.
Climate change might even make it useful here, in a nation often inundated by floods. As rising
seas seep deeper into land, the low water table will be poisoned with salt. The Dutch may have to
use the air to quench their thirst.
Here's how it works. The Rainmaker's turbine powers a heat pump that cools the air, creating
condensation. The water is stored in a tank near the base of the windmill. Results can vary,
depending on air temperature and humidity. The higher, the better.
Under ideal conditions -- warm temperatures and high humidity -- the turbine can produce 7,500
liters, or 1,980 gallons, every day, van der Vliet said. It's much lower in arid areas, like the Middle
East, Africa and Australia, where water is in greater demand. In Jordan, for example, the unit would
produce just under 400 gallons daily.
"We haven't tested the final windmill at all," he cautioned, noting that those results come from a
computer model based on the production of a prototype turbine.
First models won't be cheap
The company is currently producing a handful of turbines, which will be tested in Texas, Portugal
and Morocco. These first turbines will each cost about €250,000, or about $356,000, an amount
that might challenge widespread deployment in developing countries.
Van der Vliet said the cost would drop significantly once the company ratchets up production and
begins buying parts at wholesale prices. By then, each turbine is expected to cost about $215,000.
But van der Vliet urges potential buyers to focus on the unit cost of water over the lifetime of the
turbine. That could be as little as 3 cents per gallon, he said.
Jim Shuttleworth, a professor at the University of Arizona's Department of Hydrology and Water
Resources, said the turbine and its counterpart, which can remove salt from seawater, "should
work."
"The novel aspect seems to be that the energy that would inevitably be required to do this ... is
supplied from the windmill, and is therefore sustainable," he said. "I suspect the amount of water it
will provide will be limited in quantity and there will be a need to empty the saline buildup in the tank
from which evaporation occurs at regular intervals."
Production of the turbine is dovetailing with a massive infusion of money into developing countries
for climate adaptation. A global accord on climate change reached in Copenhagen last week calls
for a $30 billion "fast start" fund to last three years. About half of that would go toward adaptation
efforts.
Beginning in 2020, developed nations committed to providing $100 billion annually to prevent
greenhouse gas emissions and prepare poorer countries for inevitable impacts.
The price tag on any adaptation technology will be looked at closely, said Heather Coleman, senior
policy adviser for climate change with Oxfam America, an international nongovernmental
organization. She couldn't comment on the air-to-water turbines, but noted that one challenge on
the ground is training people in remote areas to maintain new technologies and expand on them.
