The race is on to create renewable-powered devices that extract water from thin air
Clean water is a necessity, but as recent events in Cape Town have shown, securing it isn't so easy.
That looming challenge has led to a competition called the Water Abundance XPRIZE. It's getting teams to build technology which can extract a minimum of 2,000 litres of water per day from the atmosphere, using 100 percent renewable energy, at a cost of two cents a litre.
One of the five finalists is Behdad Moghtaderi from Australia's University of Newcastle, whose team has developed a process which heats the air first, before cooling it.
"We went into the competition wanting to keep the technology as simple as possible to ensure it would have worldwide applications, especially for developing countries," Moghtaderi said in a statement.
