Osmotic power plant!

Reverse osmosis is a known process to separate salt from water. In this process, energy is used (generally electricity) and the process occurred through the membranes. Now, the Norwegians want to do the other way around. When rivers with sweet water meet seas with salt water, the salt molecules will be diffused through the coming water. So, why not getting electricity with this osmotic process. More information in Swedish here!
