Perennial water shortages in California will likely only grow worse due to climate change. But emerging technologies offer hope—if Californians can stop taking water for granted, says David Feldman, UCI professor of urban ...
Given that mining to extract high-grade mineral ores is wastefully energy intensive, exhaustible, and bad for the environment, scientists have been scouting for alternatives. A group of Korean researchers, led by Professor ...
Global drinking water scarcity is a severe problem for humans. Water purification consumes a large amount of fossil energy and generates secondary pollution.
Compressed blocks of pulverized coal can be used as the basis of sunlight-powered off-grid water purification. The technology is already being progressed by commercial partners toward pilot-scale production of drinking water.
In the heyday of the Ein Gedi spa in the 1960s, holidaymakers could marinate in heated pools and then slip into the briny Dead Sea. Now the same beach is punctured by craters.
Inspiration struck Yi Zheng on a summer visit to a local dairy farm. There were cows and horses and, Zheng noticed, that meant that there was manure everywhere.
Portland, Ore., USA: Coastal regions and small ocean islands face significant risks from rising sea levels due to climate change, because waters can flood and inundate low-lying land surfaces. "Climate change has become a ...
Converting seawater into fresh water is important in water-scarce countries. For that process, certain charged particles—known as ions—have to be removed from the water. However, some ions are difficult to remove from water ...
Scientists at Sandia National Laboratories and their collaborators have developed a new membrane, whose structure was inspired by a protein from algae, for electrodialysis that could be used to provide fresh water for farming ...
Engineers at MIT have developed a new approach to removing lead or other heavy-metal contaminants from water, in a process that they say is far more energy-efficient than any other currently used system, though there are ...
