Eco Factor: Sustainable skyscraper to produce fresh water from seawater.
The UNO and the World Water Council estimate that there is only about 1 percent of liquid fresh water present in the world, and the world might be heading toward a crisis affecting half the worldwide population by 2030. Designers over at the Design Crew for Architecture have come up with a sustainable tower that uses natural systems to desalinate seawater, without consuming electricity.
The bubble-shaped skyscraper, which is being touted to be a freshwater factory, is filled with mangroves that can convert saltwater into potable water, which can then be used to grow food crops. The tower will be made up of several circular tanks that will be filled with brackish water. Mangrove plants thrive on brackish water and perspire fresh water. After evaporation, the fresh water condenses on the walls of the greenhouse and can be collected in freshwater tanks.
The designers estimate that one hectare of mangroves should be able to produce up to 30,000 liters of freshwater a day, which can irrigate a one hectare field of tomatoes each day.
