The unexpected power of poop

Researchers at Stanford University have found a way to harvest considerable amounts of electricity from an unlikely source: poop. In a paper published this month in the Proceedings of the National Academy of Sciences, Xing Xie and his team of engineers describe a “microbial battery” capable of generating electricity from naturally occurring sewage bacteria.
Deriving energy from feces is hardly a new concept, but previous attempts have struggled to do so efficiently. The Stanford team’s innovation involves their use of so-called exoelectrogenic microbes, which create electric energy as they consume organic material. The researchers clustered groups of these wired microbes around the negative node of the battery, where they attach to…
