Now, a gadget that makes water 'out of thin air'

London (PTI): It's a gadget straight out of a science fiction movie -- a machine that scientists claim can make water out of thin air. An international team at Canadian firm Element Four has developed the gadget, called Water Mill, which its hopes could actually become the greatest household invention since the microwave.

According to the scientists, using the same technology as a de-humidifier, the gadget could create a ready supply of drinking water by capturing it from an unlimited source -- the air, the 'Daily Mail' reported. The Water Mill works by drawing in moist air through a filter and over a cooling element that condenses it in water droplets -- it can produce up to 12 litres a day and generate more water when storms pass over, as the humidity in the air increases.

According to the scientists, the machine not only offers an alternative to bottled water in developed countries, but it is a solution for the millions who face a daily water shortage. And, in keeping with its eco-development, the machine uses the same amount of electricity as three light bulbs. "The demand for water is off the chart. People are looking for freedom from water distribution systems that are shaky and unreliable," Jonathan Ritchey, who led the team, was quoted by the British newspaper as saying.

The Water Mill, which is about 3ft wide, is likely to cost 800 pounds and a litre of water will cost around 20 pence to produce.
