Researchers at the Technion-Israel Institute of Technology in Haifa say they have developed a stand-alone system capable of producing water from air, including in desert regions.Described as the “first technology of its kind in the world,” the energy-efficient system aims to assist small and isolated communities far from freshwater and saltwater sources.

Unlike existing water-from-air technologies, based on cooling condensation techniques, the system is based on a two-stage cyclic process: first separating moisture from air by absorption using a highly concentrated saline solution, and then separating the moisture by condensing the vapor under subatmospheric pressure conditions.
“Besides being energy efficient, the new technology offers an additional advantage: As part of the process, the water undergoes also pollutant-removal processes,” said Prof. David Broday, who developed the technology with Prof. Eran Friedler.“Our technology turns water into a commodity as it enables water to be produced anywhere in the world without being dependent upon existing sources of liquid water,” he said.Approximately 13% of the world’s population is expected to face insufficient availability of drinking water by 2025, according to World Health Organization estimates. Ensuring universal access to water and sanitation is one of the United Nation’s 17 sustainable development goals for 2030.

1. Am interested in this technology producing water from air. How can access the machine for use in Sierra Leone?

2. That's an interesting technology. Hope the production cost is affordable 

3.  Do you have any published paper related to this technology or any  scientific report or technical ? Is there any cost analysis has been done on the technology?

4. Dear professors, with all due respect, psychrometric chart shows a maximum of 20 gm/kg of air (2 %) at 100% humidity, see for yourself what you are up to??

5. Great summary by Jerusalem Post.   We need a technical report.   

6. Fantastic solution 

7. What is the quantity produced per day? the time required to produce that amount? the amount of energy required?

8. This looks like a terrific advance, but the equipment in the photo appears complicated. Will this be able to be produced economically?  How much operation and maintenance would be required?

9. Please, tell us about perfomance and cost of this process

10. Great advance!. However the final solution is an energy efficient process able to remove CO2 from air, mix It with other pollutant or massive waste and get absolutely new water. As we have learned any extractive process (from the land, air or sea) is a long-term sustainable solution.

11. please more details about this technique

     

12. That's awesome. 

13. @ Good day, If it is possible, I would like to see the total article

14. Can this work even if humidity is low.What is the cost per liter or energy required for  liter of water produced?
