Now, I do not state my support for this new water technology, but Air-Water Corp – a Florida-based outfit – claims to have created a machine that will effectively extract humidity from the air to produce 25 to 5,000 liters of water each day, if the conditions are right. These machines need high humidity (above 55 percent) and high temperatures (above 65 degrees) to operate. Air-Water Corp just delivered their first village-based unit to Jalimudi in Andhra Pradesh, India. The unit cost Rs. 3 lakh, that is 6,156 US dollars. It is unclear how much electricity this machine needs to operate, but it might be able to produce up to 1,000 liters of water each day.

Really, the concept is nothing entirely new because people have known how to take water from the air for centuries. Rainwater harvesting is used in areas with limited surface water or ground water sources. More recently, people have started to use fog nets to collect condensed water from the air. Some fog nets are able to collect up to 200 liters of water each day.
So, is it worth it to buy a machine for 6,000 US dollars that uses an unknown amount of electricity to create water from the air?
We will have to wait and ask Jalimudi village a year from now. But, one thing is for sure, the fact that Air-Water Corp is pursuing a 2 million dollar lawsuit against a sub-contractor that built these units for “repeated deliveries of faulty and sub-standard machines to Air Water’s customers” is a bit scary.
