Japanese Power Plant Turns Saltwater Into Electricity (www.theguardian.com)

It's not -a lot- of electricity ... a couple of thousand kWh per day. It's also used to de-salinate ocean water ... of which there's plenty.

From what the article says, it's actually a pretty cool way of improving desalination plants. They use the left over brine, from desalination, that has a very high concentration of salt, and use it as the high salt concentration side, with regular seawater being used on the other side. This both gives them free energy and reduces the side effects of pumping that extremely salty water into the sea by diluting it.
