Italian company Studiomobile have developed their ground breaking Seawater vertical Farm. It uses seawater to cool and humidify greenhouses and the desalinated water would be used to irrigate crops. This is a major issue in the Middle East and Dubai where the company has got the project.
There is absolutely no water and greenhouses need constant humidifying and watering. This Seawater vertical farm aims to solve all those problems. Interestingly, the design itself is quite chic and the way the device is built is aesthetically appealing.
In my opinion, these kinds of designs must be used in other cities too, where water is a problem and irrigating plants and crops can be done using sea water. If you are in a country where there is an abundance of sea water but no fresh water, you must perhaps contact these guys!
