  • Researchers in Australia recently announced the launch of a new device that, they say, absorbs water from air to produce drinkable water.
  • 2
  • Researchers at the University of Newcastle call the device the Hydro Harvester.
  • 3
  • They said it can produce up to 1,000 liters of drinkable water a day, adding that it could be "lifesaving during drought or emergencies."
  • 4
  • The Australian team said that unlike other atmospheric water generators, their invention works by heating air instead of cooling it.
  • 5
  • The device absorbs water from the atmosphere.
  • 6
  • Solar energy or heat from other industrial processes can be used to produce hot, wet air.
  • 7
  • After heating, the air cools, producing water for drinking or watering crops.
  • 8
  • Behdad Moghtaderi of the University of Newcastle's Centre for Innovative Energy Technologies told VOA how the technology operates.
  • 9
  • "Hydro Harvester uses an absorbing material to absorb and dissolve moisture from air. So...we use renewable energy..." Moghtaderi said.
  • 10
  • He added, "When you condense water contained in that air you would have the drinking water at your disposal."
  • 11
  • The researchers say the device can produce enough drinking water each day for a small rural town of up to 400 people.
  • 12
  • It could also help farmers keep livestock alive during droughts.
  • 13
  • Moghtaderi said the technology could be used in parts of the world where water is limited.
  • 14
  • Researchers thought their device would be useful because Australia's climate is dry.
  • 15
  • "More than 2 billion people around the world, they are in a similar situation where they do not have access to...high-quality water and they deal with water scarcity," Moghtaderi said
  • 16
  • Studies of the technology will be done in several Australian communities this year.
  • 17
  • The World Economic Forum (WEF), a nonprofit group based in Switzerland, says water scarcity continues to be a problem worldwide
  • 18
  • The WEF said getting water from the atmosphere is a "promising emergency solution that can immediately generate drinkable water using moisture in the air."
  • 19
  • However, the group warns that the technology is costly.
  • 20
  • It estimates that one mid-sized device could cost between $30,000 and $50,000.
