It is pretty rare I hear about a different idea in the alternative energy world. This struck me as pretty clever however, although I cannot vouch for how good of an idea it actually is.

We all know that it takes energy to remove salt from water. It is less obvious you can do the reverse to make energy. Essentially you use the pressure created when one side of a membrane is fresh water, and one side is salt water to run a turbine. That is probably unclear to most people reading this so I should go on explaining but it is easier to link this article it does a fairly good job of explaining it.
