Small units that purify household sewage could provide a source of electricity for urban and remote communities in the developing world, according to researchers.
The units would be populated with Shewanella oneidensis, one of several types of bacteria that can break down organic matter in sewage, producingelectrons and protons. If the sewage is placed between electrodes with the bacteria present, this process can be harnessed to generate an electrical current.

The rods connect to a cable that snakes out of the head and down the neck to a battery-operated regulator embedded below the collarbone. Most often the DBS system is used to treat chronic pain and Parkinson’s disease and in research against intractable depression.
