Breakthrough technology turns filthy sewage into clean energy

Last year we reported on a new way of gathering power from wastewater, one that combined power generating from salinity gradients between salt and freshwater.

But what happens if you're somewhere inland, where there isn't any saltwater to be had? The same group of researchers have now published a way of getting around that hurdle, too.
