This idea is so good that it has an entry in the  Museum of Unworkable
Devices Annex.
<http://www.lhup.edu/~dsimanek/museum/annex.htm#osmosis>

The entry also refers back to an answer given in April, 1972
Scientific American.

This idea was also discussed last year on:

However, although the stand-alone idea doesn't work, similar systems
with the addition of pumping mechanisms are already in use around the
world. Some just using the cold water for cheap air-conditioning, etc.
And some are producing remarkably cheap freshwater. As you might
expect, this is a growth industry world-wide.
