Some types of bacteria living in seafloor mud can generate enough electricity to power small electronic devices, field tests have shown. The months-long trials may herald a new generation of fuel cells that can supply reliable low-voltage power to future networks of ocean-bottom sensors in long-lived instruments for which changing batteries would be impractical, if not impossible.
