A wind-driven device could provide an unlimited water supply by harvesting water from the air, says its Australian inventor.
The wind carries in the water and [provides] the power required to separate that water from the wind," says Whisson, who is based in Perth.
He says there is a huge amount of water in the atmosphere that is replaced every few hours. This means the whole world could just use water from the air without disrupting the environment.
Whisson says the system would even harvest significant amounts of water in areas with low humidity.
He says a 4 metre square device could extract an average 7500 litres of water a day.
