“Eventually, we will require to find a method to increase the supply of freshwater as conservation and recycled water from existing sources, albeit necessary, will not be enough to fulfill human needs. We believe our freshly proposed technique can do that at big scales,” stated Illinois professor Praveen Kumar.
A nearly endless supply of fresh water exists in the kind of water vapor above Earths oceans, yet remains untapped, according to researchers. A new research study from the University of Illinois Urbana-Champaign (UIUC) is the very first to recommend an investment in brand-new infrastructure capable of collecting oceanic water vapor as an option to minimal products of fresh water in different areas all over the world.
The study evaluated 14 water-stressed places throughout the world for the expediency of a theoretical structure capable of catching water vapor from above the ocean and condensing it into fresh water– and doing so in a way that will stay practical in the face of ongoing environment change.
Kumar, graduate student Afeefa Rahman and climatic sciences teacher Francina Dominguez released their findings today (December 6) in the Nature journal Scientific Reports. The research study was led by Praveen Kumar, teacher of civil and ecological engineering and executive director of the Prairie Research Institute.
“Eventually, we will require to find a way to increase the supply of freshwater as preservation and recycled water from existing sources, albeit essential, will not be adequate to satisfy human needs. The background shows significantly lower-than-normal water levels in the Mississippi River near Grand Tower, Ill. “The existing regions experiencing water deficiency will likely be even drier in the future, intensifying the problem,” Dominguez said.” The climate forecasts reveal that the oceanic vapor flux will only increase over time, providing even more fresh water supply,” Rahman stated.” The difference is that we can guide where the evaporated water from the ocean goes,” Dominguez said.

” Water scarcity is a global problem and strikes near to home here in the U.S. regarding the sinking water levels in the Colorado River basin, which affects the entire Western U.S.,” Kumar said. “However, in subtropical areas, like the Western U.S., close-by oceans are continuously evaporating water since there is sufficient solar radiation due to the really little cloud coverage throughout the year.”
Previous wastewater recycling, cloud seeding, and desalination strategies have actually met just restricted success, the researchers said. Though deployed in some locations around the world, desalination plants deal with sustainability issues due to the fact that of the brine and heavy metal-laden wastewater produced– so much so that California has recently rejected procedures to add new desalination plants.

” Eventually, we will require to discover a way to increase the supply of freshwater as conservation and recycled water from existing sources, albeit important, will not be adequate to fulfill human requirements. We believe our freshly proposed approach can do that at large scales,” Kumar stated.
The researchers performed economic and climatic analyses of the positioning of hypothetical offshore structures 210 meters in width and 100 meters in height.
Through their analyses, the scientists concluded that recording wetness over ocean surface areas is possible for numerous water-stressed areas worldwide. The estimated water yield of the proposed structures could provide fresh water for big population centers in the subtropics.
One of the more robust forecasts of environment change is that dry areas will get drier, and wet areas will get wetter. “The existing areas experiencing water shortage will likely be even drier in the future, intensifying the problem,” Dominguez stated. “And sadly, individuals continue transferring to water-limited areas, like the Southwestern U.S.”
This forecast of increasingly arid conditions prefers the new ocean vapor-harvesting technology.
” The environment forecasts reveal that the oceanic vapor flux will just increase over time, offering even more fresh supply of water,” Rahman said. “So, the idea we are proposing will be practical under environment modification. This supplies a efficient and much-needed method for adjustment to environment modification, especially to susceptible populations living in arid and semi-arid areas of the world.”
The scientists stated one of the more elegant functions of this proposed service is that it works like the natural water cycle.
” The distinction is that we can assist where the evaporated water from the ocean goes,” Dominguez said. “When Praveen approached me with this idea, we both questioned why no one had thought of it previously due to the fact that it appeared like such an obvious solution. It hasnt been done previously, and I think it is because scientists are so focused on land-based services– but our study reveals other options do, in reality, exist.”
The researchers said this research study unlocks for unique facilities investments that can effectively attend to the increasing worldwide scarcity of fresh water.
