As reported in DNA, according to the Niti Aayog’s ‘Composite Water Management Index’ report, 52 percent of India’s agricultural area continues to remains dependent on rainfall.
Therefore, any sort of water scarcity causes severe distress to farmers, who fight several other battles on a daily basis. Well, a new invention could ease things up a bit. According to the Times of India, the Hyderabad-based Indian Institute of Chemical Technology (IICT), is working on a low-cost atmospheric water-generator (AWG) that will literally draw water from the air.
So, how does this work?
Once the AWG is installed and switched on, the machine will trap the air, and cleanse it of all pollutants, proceeding to draw out the moisture. So, the higher the temperature and the humidity, the more the quantity of water which will be produced from the air. A prototype of this is already on display at the IICT Tarnaka Campus. Production is likely to begin in IICT Hyderabad’s Moula Ali campus in August 2018.
AWG technology isn’t new, and there are several imported AWG’s available in India. However, they are expensive in cost and operation. This machine, on the other hand, is indigenous and inexpensive and produces drinking water at an affordable price. It is estimated that a litre of potable water, will cost approximately Rs 2. The price is likely to go down, once this technology spreads.
IICT has signed a memorandum of understanding (MoU), with Maithri Aquatech, for the commercial production of these machines, called Meghdoot, to help people in drought-hit areas.
Explaining the importance of the machine, IICT Director, S Chandrasekhar, and Maithri Aquatech Managing Director K Ramakrishna, spoke of how a pail of potable water is a daily physical strain especially for women-folk in far-flung areas. Arun Tiwari, an associate of former president Dr APJ Abdul Kalam, spoke optimistically of the AWG as a boon to those living in water-scarce regions.
With the machine capable of pulling out water from the air, farmers will hopefully no longer have to rely on often-erratic rainfall for their crops.
