Using bacteria and waste water to make electricity

Smarter energy and water solutions are everywhere.

All of us use water and in the process, a lot of it goes to waste. Whether it goes down drains, sewers or toilets, much of it ends up at a wastewater treatment plant where it undergoes rigorous cleaning before it flows back to the environment. The process takes time, money and a lot of energy.

 What if that wastewater could be turned into energy? It almost sounds too good to be true, but environmental engineer Bruce Logan is working on ways to make it happen.  See:  Bacteria, energy producers of the future? 

Here is a direct video link.
