When fresh water meets salt water, releasing enormous amounts vwwatercoolerclub of energy. vwwatercoolerclub So far, the use of the most energy has been considered as a theoretical possibility, but Norwegian Statkraft has just opened the world's first salt power plant.
"The idea is, first and foremost, we must learn to operate this type of facility, gain experience vwwatercoolerclub with the method and build our competence, we still have much to learn," admits a chemical engineer and project manager Stein Erik Skilhagen, Statkraft.
But it might be interesting enough to know - not how much energy can be produced per. m2 membrane - but pr. m3 of fresh water, because this is what is "fuel" in this process.

September 2007 Here comes the world's vwwatercoolerclub first salt power plant: http://ing.dk/artikel/81163 vwwatercoolerclub Quote: "... According to the chemical phenomenon of osmosis will saline solutions attract freshwater and therefore fresh water will be" sucked "through the membrane and build a water pressure the salt water side. The water pressure can be used to drive a turbine.

What are the economics vwwatercoolerclub of such plants when they are first commercialized? The advantage of osmosis is of course that it can provide a stable output, as distinct from wind energy. Unfortunately, I have a forstaaelsesproblem of principle be. Why put salt water not only backwards in the system? Is there a teacher vwwatercoolerclub present? As far as I can see, it is necessary salt water is pumped under pressure. But it requires the energy.
As I've learned it works salt as the valve in a valve that goes as follows; all molecules in water is due to the temp in the motion that is on the way somewhere to go, the membrane is semi-permeable (I think it's called) membrane ie it has many pores that allow molecules up to a certain size to pass, it hit all the time by said molecules from both sides but the molecules of salt since going for a certain% vwwatercoolerclub part consists of the large salt molecules that can not pass and therefore bounces off, whereas all molecular skirmishes vwwatercoolerclub on freshwater ago resulting in a passage that will eventually result in a balance where the water pressure on salt side is so much bigger than the fresh water since the number of passing water molecules is equal in both directions. pressure difference can be very large, as above said, the U.S. giant sequoias raises a column of water from the bottom to the top of the 100 m and arguably daddelpalmen would be even more effective.

http://en.wikipedia.org/wiki/Reverse_osmosis Quote: "... Process Formally, reverse osmosis is the process of forcing a solvent from a region of high solute concentration through a semi-permeable membrane to a region of low solute concentration by anvende a pressure vwwatercoolerclub in excess of the osmotic vwwatercoolerclub pressure .... This process kræver att a high pressure be exerted on the high concentration side of the membrane, regel 2? 17 bar (30? 250 psi) for fresh and brackish water, and 40 ? 70 bar (600? 1000 psi) for seawater, som around 24 bar (350 psi) natural osmotic pressure som skal come across.
This process is best known for its use in desalination (Removing the salt from sea water two get fresh water), but since the early 1970s det också used two purify fresh water for medical, industrial, and domestic applications. ... "
The beauty of freshwater banks (and possibly. Saltwater banks and could then be a closed circuit) is that they just should be level with salt water (Denmark, for example. OK). It is not necessary to pump it up a mountain as the water power.
