JERUSALEM: An Israeli company has developed a new and inexpensive technology that produces drinking water from thin air a method that can address the problem of water scarcity in developing countries such as India.

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 Atmospheric Water-Generation Unit can be built as a residential unit and serve as a perfect water supply solution for homes in India," said Kohavi.

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.

"It looks simple, because air conditioning is extracting water from air. But the issue is to do it very efficiently, to produce as much water as you can per kilowatt of power consumed," said Kohavi.

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.

I heard and even saw of such system in late 90's from a Singaporean company, the CEO was a woman. Don't know what happened to that company most likely US force closed it. But now there are many companies from various Nations.

Condensation... the water needs to be purified the process wastes more energy per amount of water it produces. I guess they use new generation of solar panels to economize the process.

Why we can not adopt this system,please somebody answer .
Perhaps because Pakistan doesn't have relations with Israel so Pakistan doesn't purchase Israel's water-saving agricultural technologies?

Since you have stolen this technology from poor country like PERU, who invented it,buying it from you will be a crime.Pakistan should not touch it, diplomatic relations or not.

I think it exists from a long time, remembering watching a documentary on it some years back, on addressing the water concerns in some parts of the world.

If you really believe that, I'm sure you'll provide references for us readers to review. Otherwise, it's just another anti-Israel calumny.

correct me if I'm wrong, but hasn't this tech been around for a few decades already? I remember watching a documentary about it in 2002.

This technology depends upon the amount of water vapour in the atmosphere. In dry, parched environments it will not be feasible at all due to very low humidity. On Israel's Mediterranean coast, this device may condense some water, but, will be totally useless in it's interior regions.

An even simpler solution is fog catchers used in Atacama desert of Chili - one of the driest places on earth. These are simple nets that capture fog coming from the adjacent sea. These nets can collect hundreds of gallons of water per day. But, this is possible only due to the presence of a large amount of humidity.

This is essentially a de humidifier. It can be bought in many stores already. Basically after it runs for a day or 2 depending on how humid it is and you end up with a bucket full of water. It is not purified but you can do that by running it through your own filter or by boiling it.

I agree. I have one in my basement. No big revolutionary idea here.
You'd be shocked at how much water these things quickly pull out of thin air. It's a lot more than 5 liters a day.
