Dr.
Ioannis Ieropoulus of the the Bristol Robotics Lab explains how
mircrobial fuel cells, pictured at right, turn urine into electricity.
The project reminds me of another one showcased at Maker Faire Africa last year: a urine-powered generator.
There’s an added benefit of the microbial fuel cell technology, too. According to researchers, passing the urine through the fuel cells “cleans” it so it can be safely discharged into the environment, eliminating the need for wastewater treatment. Maybe sewage plants could double as power plants. Pee pee becomes a win-win.
If the output of the fuel cells could be expanded, what applications can you imagine for this technology?
