Osmosis

Her Royal Highness Crown Princess Mette-Marit of Norway officially opened Statkraft's osmotic power plant prototype on 24th November

Using a modified microbial fuel cell, an international team of researchers has proven a process that cleans wastewater can also remove 90 percent of salt from brackish water or seawater while generating electricity.

The mini-mobile-modular (M3) “smart” water desalination and filtration system could help determine the feasibility of using available water as a source for a large-scale desalination plant.

Green energy comes in many guises these days, from wind-power to wave-power. One of the more compelling of the new kids on the eco-energy block is salinity power, which uses the concurrence of salt-water and freshwater in estuaries and marries it with the natural, effortless process of osmosis.

Hydration Technologies has developed a passive filtration system that creates a safe, clean drink from any contaminated groundwater without the use of power, pumping or chemicals.
