Lima billboard is tapped for drinking water

(Phys.org)—A billboard in Lima, Peru, created by ad agency Mayo DraftCFB in collaboration with the University of Engineering and Technology (UTEC), captures the air's humidity and turns it into potable water for Lima residents. ...

Carbon nanotubes developed for super efficient desalination

Membrane separations have become critical to human existence, with no better example than water purification. As water scarcity becomes more common and communities start running out of cheap available water, they need to ...

Radical desalination approach may disrupt the water industry

Hypersaline brines—water that contains high concentrations of dissolved salts and whose saline levels are higher than ocean water—are a growing environmental concern around the world. Very challenging and costly to treat, ...

Desalinating seawater with minimal energy use

At a pilot facility in Singapore, Siemens has cut the energy needed to desalinate seawater by more than 50 percent. The plant processes 50 cubic meters of water per day, consuming only 1.5 kilowatt-hours of electricity per ...

Drinking water from the sea using solar energy

One of the main ways to obtain drinking water in hot, dry countries surrounded by sea or ocean is through desalination. European researchers developed a high-efficiency and low-cost desalination technology by exploiting solar ...
