Ancient Indian's were very creative about condensing water out of thin air through various methods like fog fences, dew ponds and air wells. However, large swathes of the country is now facing acute shortage of clean and safe drinking water. 
 

But a start-up has come to their rescue and thinks they can play a vital role in alleviating the ciris, by producing water out of thin air. 'Urav Labs' a start up of the alumnus of National Institute of Technology, Calicut, has developed a device that could source potable water from thin air. The apparatus can produce up to 70 litres of fresh water per day and will cost only ₹2/ltr. 
 

The device works on vapour compression refrigeration system and will convert the humidity in the atmosphere into water. The water collected is purified with a filter and is mixed with minerals to make it potable. 
 

The apparatus will work under specific atmospheric conditions. It will generate maximum water when atmospheric humidity is above 30% and temperature over 12 degree celcius. The device is much suitable for Kerala as the atmospheric humidity in the state is above 60%. 
 

The team comprising of NIT alumnus Swapni, Sandeep, Pardhasai and Venkatesh also has plans to develop the machine further to produce water for as low as ₹1.2/ltr. The device could be connected to internet to analyse the climate and to check the quality of water and air.
 

It could be installed in public places to ensure availability of high quality drinking water.
