Deriving electricity from wastewater and bacteria

Deriving electricity from wastewater and bacteria

By Gaia Smith

NATIONAL UNIVERSITY OF SINGAPORE, SINGAPORE. In an energy production scheme that combines two inventions from different universities, a student found a way to derive electricity from wastewater. This scheme utilizes methane and hydrogen produced by bacteria in wastewater treatment to feed a microbial fuel cell that would convert methane and hydrogen into a source of energy that would fuel electricity needs. Increased yields of methane from the combination would be transformed into energy utilized by humans.

The scheme used improved methane production methods from Nanyang Technological University and bioreactor models from Harvard University.

Calling this invention wastewater would be an understatement. Bacteria is your next energy provider and it has a potential to be a very vast source of energy for Singapore. The source may be considered dirty, yet it gives the Earth another chance towards a cleaner future.
