Could “switchable salts” be a game-changer for desalination market?

Could “switchable salts” be a game-changer for desalination market? | Sustainable Energy | Scoop.it

Canada, the land of abundant fresh water, has little need for desalination technologies to quench the thirst of its citizens.

This makes it all the more amazing that Canadians are behind some of the most innovative new approaches to taking salt out of seawater, the need for which is expected to rise substantially over the coming years.

According to a recent report from the National Intelligence Council, which reflects the combined input of 16 U.S. intelligence agencies, global water demand will exceed sustainable supplies by 40 per cent by 2030.

L'éolienne qui produit de l'eau potable

L'éolienne qui produit de l'eau potable | Sustainable Energy | Scoop.it

En captant l'humidité présente dans l'air, l'éolienne testée par l'entreprise Eole Water parvient à produire jusque 1000 litres d'eau par jour. Une innovation qui pourrait résoudre en partie les problèmes d'accès à l'eau potable.

 

On pourrait croire à un mirage, mais non. C’est bien de l’eau qui s’écoule en plein désert. Lors des premiers essais à Mussafah, à proximité d’Abu Dhabi (Émirats arabes unis), la jeune entreprise française Eole Water a concrétisé son slogan « Donnez-nous de l’air, nous vous donnerons de l’eau ».

Ne risque-t-on rien à retirer l'humidité de l'air dans les déserts ?

De quel risque parlez-vous ? Je vois aussi une application sur des îles loin des côtes sans eau potable ou dans des certaines zones moins arides que le désert.

French company uses wind turbine to create fresh water

French company uses wind turbine to create fresh water | Sustainable Energy | Scoop.it
(Phys.org) -- French company Eole Water has announced that they have developed and are now in the process of selling wind turbines that have been modified to produce fresh drinking water.

 

"The turbines work by combining two current types of technology; traditional generation of electricity using wind as the driving force, and compressors commonly used by dehumidifiers and refrigerators."

 

"The water that is produced drips down to the base of the turbine tower where it is filtered and delivered for use."

 

"The new turbines do have one major drawback and that is the price..."
