Bacteria generate cleaner power and water

Microbial fuel cells can store away carbon dioxide as well as produce electricity, according to an international team of scientists.

Microbial fuel cells offer a clean and efficient way of producing energy because the microbes that power them can feed off almost any organic waste. Xia Huang and colleagues at Tsinghua University, Beijing, China, and Ghent University, Belgium, demonstrated that sunlight helps microbes use dissolved CO2 (bicarbonate) in wastewater to produce electricity.
