World’s first osmotic power plant

Norway-based company Statkraft has just opened the world’s first osmotic power plant, tapping into the emissions-free energy produced when fresh water and salt water mix Osmotic power harnesses osmosis, the natural process by which a solute in solution travels from an area of lower to higher concentration across a semi-permeable membrane (permeable to the solvent but not the solute).  In the case of osmotic power, the combination of salt water and fresh water produces movement from areas of lower to higher salinity.  Osmotic pressure created during this process is the potential force that can be used to power energy generation turbines in an osmotic power plant.

The Statkraft plant is being opened as a testing site for the technology, but it has the potential to output up to 1,600-1,700 terawatt-hours per year, or approximately 50% of the European Union’s total power production.

NYC commissioners roundtable interview

Transportation Commissioner Janette Sadik-Khan, Design and Construction Commissioner David Burney, Planning Commissioner Amanda Burden, and Parks Commissioner Adrian Benepe

In a roundtable conversation hosted by The Architects’ Newspaper, four New York City Commissioners–Transportation Commissioner Janette Sadik-Khan, Design and Construction Commissioner David Burney, Planning Commissioner Amanda Burden, and Parks Commissioner Adrian Benepe–discuss recently designed and developed projects as well as what they believe is achievable during Mayor Bloomberg’s next four years, especially given tightening fiscal constraints.  It’s a pretty in-depth interview, and it’s great to hear the shared thoughts of this group, who have helmed some major projects in the City over the last eight years, including the High Line, the pedestrianization of Broadway in Times and Herald Squares, Brooklyn Bridge Park, Yankee Stadium redevelopment and, of course, Freshkills Park.
