SOURCE World is without doubt one of the many firms all over the world extracting water from the air, with the hope of serving to water-scarce communities. Nevertheless, its know-how has a sustainable twist. Named Hydropanels, its gadgets are powered by built-in photo voltaic panels.
“You are in a position to harvest water from the air utilizing photo voltaic and nothing else, no want for electrical energy, no want for (a) grid, no want for infrastructure — it is completely self-sufficient,” explains Vahid Fotuhi, the corporate’s vp for Europe, Center East and Africa.
Atmospheric water mills (AWGs), like SOURCE’s, are machines that produce potable water from surrounding air. These gadgets have been round for a few decade and historically they’re based mostly on condensation — cooling water vapor to gather water droplets.
This course of, nonetheless, can devour lots of electrical energy and plenty of of those early applied sciences solely work in locations with excessive air humidity. These constraints are what prompted SOURCE, previously generally known as Zero Mass Water, to develop a extra versatile and sustainable answer.
In Dubai, the place the corporate’s largest water farm is situated, it produces 1.5 million liters of water yearly. SOURCE plans to create a plastic-free bottled water model and promote it to inns and resorts, at about the identical worth as different bottled water manufacturers.
SOURCE has put in its hydropanels all over the world at hospitals, colleges and work websites which have difficulties accessing water. It has additionally attracted business purchasers — notably in nations catering to vacationers in remoted landscapes, such because the desert.
“Within the Center East, we have seen lots of curiosity within the hospitality sector as large manufacturers search for a extra sustainable answer for water to accommodates Millennials, who’re in search of demonstrated sustainability,” says Fotuhi.
At present, SOURCE’s flagship hospitality providing is in a luxurious desert camp in Dubai, the place its Hydropanels produce consuming water on website. Fotuhi believes it exhibits the scalability of those water mills, which may function as one panel in a household house to or a quantity put in at massive resort resorts. Its subsequent partnership might be in Saudi Arabia’s Crimson Beach, the place a improvement firm is aiming to construct 18 inns that may serve SOURCE’s water.
Combating water shortage?
In keeping with Keith Hays, vp of Bluefield Analysis, an advisory agency that addresses water challenges, SOURCE’s design is completely different from different AWGs as a result of it combines solar-based energy provide and water seize mechanism throughout the similar construction, enabling off-grid operation. “Different methods normally have a separate panel or connect with the grid,” he explains.
Over 2 billion folks dwell in nations experiencing excessive water stress and whereas the handfuls of firms engaged on AWGs hope their gadgets will assist remedy this disaster, that may be unlikely, in keeping with Hays.
Excessive up-front prices imply it takes round 10 years for AWGs to be cost-competitive, he says and so they usually produce a fraction of the water {that a} properly or seawater desalination system can provide.
Plus, Hays says, AWGs require important land, and distribution networks that are not as ubiquitous as different water options. He believes AWGs are extra environment friendly when mixed with different water provides. “They are often seen as a complement to current consuming water methods, lowering (the) footprint of plastics and providing auxiliary assist,” he says.
This problem is one thing that Fotuhi acknowledges, explaining that Hydropanels require the faucet or a bottling facility to be close by, and never each state of affairs permits that. However however he believes they provide clear environmental advantages.
“Trying on the financial savings from an environmental perspective and from a sustainability perspective, the worth proposition stays very robust,” says Fotuhi.
