Making water in a desert, from daylight and air

SOURCE International is without doubt one of the many firms world wide extracting water from the air, with the hope of serving to water-scarce communities. Nonetheless, 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 a whole lot 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 often called Zero Mass Water, to develop a extra versatile and sustainable resolution.

Its photo voltaic panels energy a fan that pulls in air. Contained in the system, the air travels by means of a sponge-like materials that traps the water vapor. As it’s collected, magnesium and calcium are added to the water to enhance its style and present doable well being advantages. Which means that mineralized consuming water will be produced from the air with renewable vitality and nil waste.

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 resorts and resorts, at about the identical worth as different bottled water manufacturers.

SOURCE has put in its hydropanels world wide at hospitals, faculties and work websites which have difficulties accessing water. It has additionally attracted industrial shoppers — significantly in international locations catering to vacationers in remoted landscapes, such because the desert.

“Within the Center East, we have seen a whole lot of curiosity within the hospitality sector as large manufacturers search for a extra sustainable resolution for water to accommodates Millennials, who’re in search of demonstrated sustainability,” says Fotuhi.

Hydropanels installed at a school in Veresdale, Australia.

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 reveals the scalability of those water mills, which might function as one panel in a household residence to or a quantity put in at massive lodge resorts. Its subsequent partnership might be in Saudi Arabia’s Purple Beach, the place a improvement firm is aiming to construct 18 resorts that can serve SOURCE’s water.

Preventing water shortage?

In keeping with Keith Hays, vp of Bluefield Analysis, an advisory agency that addresses water challenges, SOURCE’s design is totally different from different AWGs as a result of it combines solar-based energy provide and water seize mechanism throughout the identical construction, enabling off-grid operation. “Different techniques often have a separate panel or hook up with the grid,” he explains.

Over 2 billion folks reside in international locations experiencing excessive water stress and whereas the handfuls of firms engaged on AWGs hope their gadgets will assist clear up this disaster, that will be unlikely, in response to Hays.

Excessive up-front prices imply it takes round 10 years for AWGs to be cost-competitive, he says and so they typically produce a fraction of the water {that a} properly or seawater desalination system can provide.

Plus, Hays says, AWGs require vital 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 techniques, decreasing (the) footprint of plastics and providing auxiliary help,” 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 standpoint, the worth proposition stays very robust,” says Fotuhi.
