Sound too good to be true? Waste treatment with certain microbial fuel cells could extract more energy out of wastewater than required to clean up the water. That would make waterpurification a win-win situation for everyone: Good for the environment, good for the water purification companies, and good for consumers who currently pay for drainage.
Of course, it’s still theory: even though fuel cells are working at a large enough scale to build the first such plant, they are not efficient enough to generate substantial income from power sales. But it’s a promising area – let’s see where this goes!
