Looking forward to the interaction re cuttong out Tankers in Delhi.

Arriving back July11 and will contact you.

US also has water problems. The Mississippi – Missouri river basin extends all the way from the Canadian border up to the Gulf of Mexico. It is flood prone.

South West US is arid and much of it is desert. They are over exploiting the water resources. The largest irrigated crop in US is grass. Grass for lawns and golf courses.

The city of Los Angeles has bought up the water resources of a large part of the Californian desert. The water is taken to LA while the locals are deprived.

But enough of US problems. We have bigger problems of our own.

I am sitting in NYC and overlooking the large Hudson River. I am envious of USA for their water resources. I am also impressed of the rules they implement and are followed. It is pristine clean. No one throws anything in the river. Ships ferry cargo up this River. We have never organised our water resources.

When I am back in Delhi, I will request you to send the water Diviner to Delhi for a day. I am currently facing same problems at the farm. I use Tankers from April to July till the rains come. I want to find a place at the farm where I can have a permanent well for to supply water through the year.

Your project in Kashmir and now in the Society should be inspiration to many.

The AWG available in India is a straightforward refrigeration – condensation type. Website is http://watermakerindia.com/company.php

The Arizona company you referred is probably this :

Sunlight + Air = Water. It’s a befuddling equation, but it’s at the heart of a new solar hydropanel developed by Arizona-based startup Zero Mass Water. The company’s SOURCE panels can be installed atop any building just like standard photovoltaics, but instead of just harvesting solar energy, they use the sun’s rays to pull water from the air. Each panel has the potential to draw up to 10 liters (2.64 gallons) of water per day.

So how does it work? Each SOURCE array consists of a standard solar panel flanked by two hydropanels. As explained by The Verge in the video above, the photovoltaic at the center of the array drives a fan and the system’s communication with the hydropanels. The hydropanels themselves consist of two different proprietary materials, one that can generate heat, and another that can absorb moisture from the air. Together they are able to condense water into an onboard, 30-liter reservoir where it is mineralized with calcium and magnesium. From there, the water can be siphoned directly to a drinking tap.

As one might guess, the amount of humidity in the atmosphere and solar energy available will affect the payout. However, Zero Mass Water says that even low-humidity and arid regions can effectively benefit. The company’s CEO, Cody Friesen, cited the array atop his headquarters as an example. “Our array on the Zero Mass Water headquarters in Scottsdale, Arizona makes water year-long despite low relative humidity. The Phoenix-Metro area can get below 5% relative humidity in the summer, and SOURCE still produces water in these incredibly dry conditions,” he said. Additional panels can also be added to optimize water collection, but there is the matter of cost.

Right now, the two-panel array costs $4000, plus installation, which runs $500. The whole system has been engineered to last 10 years, which according to Treehugger’s calculations, this averages out to about $1.23 per day, or between $0.12 and $0.30 per liter of H2O.

To date, hundreds of panels have been set up in eight countries around the globe. Zero MassWater says the installations represent a combination of early adopters who have paid out of pocket for the technology and developing areas and emergency situations where funding has been provided by donors, NGOs, or other institutions.

There is nothing complicated about utilising the free rain water that we get. A little effort is required, that is all.

The main thing is that grassroots effort is required. We cannot depend on the government, because the government always looks at grandiose projects.

More than 150 years ago, our ancestors — who were mostly illiterate — undertook this all over Central Kerala. Probably other areas also. There is no complicated science involved, just a few simple measures.
