Drinking water out of thin air!

Using the technology, a litre of water can be produced for a mere Rs 1.50, as compared to Rs 15 for a litre of bottled water, the company claims. The Atmospheric Water-Generation Units created by Water-Gen use a "GENius" heat exchanger to chill air and condense water vapour. The clean air is passed through the heat exchanger system where it gets dehumidified. The water is then removed from the air and collected in a tank inside the unit, CNN reported. "From there the water is passed through an extensive water filtration system which cleans it from possible chemical and microbiological contamination," co-CEO Arye Kohavi said. "We believe that the products can be sold to developing countries in different civilian applications. For example in India, (drinking) water for homes is not available and will also be rare in the future. The company claims its water generator is more energy efficient than other such companies as it uses the cooled air created by the unit to chill incoming air.

The system can produces 250-800 litres of potable water a day depending on temperature and humidity conditions. According to Kohavi, it only uses two cents' worth of electricity to produce a litre of water.
