Electricity From Salty Water
BuzzSkyline writes "It's possible to produce energy by simply mixing fresh and salty water. Although chemists and physicists have long known about the untapped energy available where fresh water rivers pour into salty oceans — it's equivalent to 'each river in the world ending at its mouth in a waterfall 225 meters [739 feet] high' — the technology for exploiting the effect has been lacking. An Italian physicist seems to have solved the problem with the experimental demonstration of a 'salination cell' that creates power given nothing more than input sources of salty and fresh water. The researcher believes that this renewable, environmentally friendly energy source could be deployed in coastal areas and could provide another addition to the green-tech roster. A paper describing the technology is due to be published in an upcoming issue of the journal Physical Review Letters."
In a time where there is a huge and rapidly growing potable water crisis, some bozo creates an economic incentive to salinate what precious fresh water there is! By Jove, Holmes, you've done it again!
Like the whole corn-based ethanol disaster never happened. Jesus H. Christ...
Not every river mouth harbors endangered species.

The best way to desalinate water is to let it evaporate from the ocean, then catch it when it falls from the sky.
