New battery uses microbes to turn sewage into energy

I realize that this is most likely AFP's doing, but this paragraph does not make any sense at all.

The researchers said their new model is simple, yet efficient, and can harness about 30 percent of the potential energy in the wastewater -- about the same rate as commercially available solar panels.

To the best of my knowledge solar panels does not turn wastewater into energy.

Congratulations, Stanford. This is heartwarming news.

Awesome news. Encourages my hope in the real possibilities of basic scientific research!
