Producing electricity at estuaries using light and osmosis

Most renewable power technologies are weather dependent. Wind farms can only operate when there's a breeze, and solar power plants rely on sunlight. Researchers at EPFL are working on a method to capture an energy source ...

Saltier waterways are creating dangerous 'chemical cocktails'

A recent study led by University of Maryland researchers found that streams and rivers across the United States have become saltier and more alkaline over the past 50 years, thanks to road deicers, fertilizers and other salty ...

How quinoa plants shed excess salt and thrive in saline soils

Barely heard of a couple of years ago, quinoa today is common on European supermarket shelves. The hardy plant thrives even in saline soils. Researchers from the University of Würzburg have now determined how the plant gets ...

Optimizing lithium-sulfur battery electrolytes for long life

In the future, lithium-sulfur (Li-S) rechargeable batteries could hold more energy and cost less than lithium-ion batteries if they can be made to last longer. A key challenge is preventing the polysulfide ions that must ...

North American waterways are becoming saltier and more alkaline

Across North America, streams and rivers are becoming saltier, thanks to road deicers, fertilizers and other salty compounds that humans indirectly release into waterways. At the same time, freshwater supplies are becoming ...

Researchers make headway in desalination technology

Engineers at the University of Illinois have taken a step forward in developing a saltwater desalination process that is potentially cheaper than reverse osmosis and borrows from battery technology. In their study, the researchers ...
