> The water could be obtained by dessicating it out of the atmosphere

"The goal is to help people," said Enrique Veiga, the 82-year-old
engineer who invented the machine during a harsh drought in southern
Spain in the 1990s. "The goal is to get to places like refugee camps
that don't have drinking water." The devices made by his company,
Aquaer, are already delivering clean, safe water to communities in
Namibia and a Lebanese refugee camp. "In the villages we visited in
Namibia, they were astonished, they didn't understand, asking where
the water came from," he said.

The machines use electricity to cool air until it condenses into
water, harnessing the same effect that causes condensation in
air-conditioning units. While other water generators based on similar
technology require high ambient humidity and low temperatures to
function effectively, Veiga's machines work in temperatures of up to
40 Celsius (104F) and can handle humidity of between 10% and 15%. A
small machine can produce 50-75 liters a day, and be easily carried on
a trolley, but bigger versions can produce up to 5,000 liters a day.
