Israeli Company Creating Drinking Water Out of Thin Air Now Used by Seven Armies (VIDEO)

Israeli water tech company Water-Gen, which has developed a technique for creating drinkable water out of air, is providing its technology to military units in seven nations including the U.S., PolicyMic reported recently.

Water-Gen’s solar or electric-powered water generators, which can sit on the ground or in vehicles such as tanks, produce between 10 and 20 gallons of fresh, cold, drinking water per day. The Tel Aviv-based company originally designed the generating unit for hydrating troops in extreme combat situations.

The generating process begins with an air filtering unit facing outside that extracts humidity from the air and works like an air dehumidifier to remove toxins from the moist air. The clean air then enters GENius, the company’s unique heat exchanging system that produces water from the humidity. The water collects at the bottom of the unit and fills up water tanks before flowing to a tap.

“Taking water from the atmosphere has not been done correctly. The tech has not changed for many years. It was based on bad assumptions, the tech was inefficient and it was very expensive,” said David Gillo, Water-Gen’s VP of business development. “We brought it to a place where it’s efficient, energy-saving and affordable enough where it’s being seriously considered.”

Watch a Reuters report on Water-Gen below:

  • Where can I buy one? I cannot find a supplier and would love to give my community some drinkable water.

  • What a wonderful device. But I do not envisage it being used commercially by homeowners in the US, particularly California and the Southwestern States, because it would make utilities less profitable. Think in terms of a combined solar/water-gen tanked system with built into every house in the US where humidity and dewpoint make it break even. So, it will not be allowed in the US.

    An example of the reasoning that will be used to prohibit that wonderful innovation in the US can be gathered from the water wars in Bolivia a decade or so ago. In Bolivia, a multinational business venture contracted with Bolivia together with the IMF and the World Bank to provide water, but required as a condition of its contract that Bolivia enact laws that punished people for harvesting rain water from their rooftops. While that didn’t work out so well for the company, the idea of doing that is clearly not far fetched for companies that can control governmental actions.

    An example of my point is this observation. Given the fact that California is in the middle of a history-making drought, such a device would be cheap at twice the price for homeowners if the government wanted to ensure potable drinking water for its citizens….But I will bet that not one inquiry has come from California as to economies of scale, e.g., cost to provide a unit to millions of households in California.

  • Is there one compact enough for survival situation or camping purposes? Hand cranked?

    There is a company operating out of Switzerland called Eurosport Active World Corp. that is using plasma technology to burn/vaporize trash, that supplies the power for the machine to create the water. It solves the “energy/power” issue that has plagued atmospheric water generators. Eurosport’s technology is better suited to larger power and water needs.

  • Well, I also had that idea years ago when I got angry at the drips from air conditioners. They are really “reverse fridges” that condense water from the (usually quite humid) summer air at their heat exchangers. When optimized and powered by renewable energy as an autonomous unit it might actually be affordable water in some near future. Certainly seawater desalination like in some emirates is an energy-consuming process (probably currently powered by oil). This could also ease some of the tensions that build up in various parts of the world over water rights (although the amounts needed for irrigation by far dwarf the amounts needed for drinking purposes only).

    Can they turn it into wine? Now that would be a invention :)

  • Always a pleasure to read about another Israeli innovation.

  • james ainoris

    Lol BDS will boycott this also….good idea yiden.Shalom

  • john prince kondowe

    I am very pleased with your new technology and am not surprised with your new technology because the Jews are well known with inventing things.

    So what I can say is keep up on inventing things but how i wish to have one for people with disabilities.

    God bless Israel as nation and its people

  • For your interest, here are average monthly data on the water-from-air resource in Tel Aviv. The units are for water vapour density [grams of water vapour per cubic metre of air]

    Jan 7.1, Feb 7.6, Mar 8.1, Apr 9.2, May 11.1, Jun 13.4, Jul 16.0, Aug 17.0, Sep 15.1, Oct 12.6, Nov 9.2, Dec 8.2

    The seasonal changes in the water-from-air resource are quite marked in Tel Aviv which is at 32°N latitude. During July and August ‘excellent’ performance of the water generator can be expected. During June, September, and October performance will be ‘good’. From March to May and November to December performance will be ‘fair’. During January and February water-from-air production will be ‘poor’ in Tel Aviv. The water-from-air machine will be a maximum of about 60% efficient at removing water vapour from the air in August. In January, the machine’s dehumidification efficiency drops to 5%. These efficiency values presume that the chilled surface in the machine is maintained at 5°C.

    The energy typically needed by dehumidifiers to condense water vapour into liquid water is approximately 0.4 kWh per litre of product water.
