This image captures the results of an experiment conducted at the U.S. Naval Research Laboratory in Washington, D.C., where scientists set up radio sensors around buildings to test whether they could locate a small transmitter by listening for its emissions. They located the transmitter, but they were less successful as the emissions got farther away. An algorithm under development could help locate an emitter with a network of inexpensive power sensors.

Advances in a plethora of military communication and situational awareness platforms have created unintended repercussions for the U.S. Navy, from the “forest of antennas” that can consume a ship’s deck to the debilitating effects of radio interference that clog airwaves and impede critical links to vessels, aircraft, drones and even satellites. Navy engineers are toiling on a handful of projects to ensure effective and secure communication links, which are so fundamental to military operations.

 Lenny Tender, a research chemist at the Naval Research Laboratory, stands in front of a tank that mirrors marine environments at the Washington, D.C., facility. Partially submerged in the tank is a Hershey Kiss-shaped buoy that scientists use to develop the benthic microbial fuel cell, a persistent power supply for marine-deployed applications.

Imagine the Energizer Bunny living at the bottom of the sea. Instead of running on batteries, it keeps going, going, going because of energy harvested from the marine environment. This concept is under development as an alternative to using man-made batteries, which need to be replaced, to run oceanographic sensors.

“Our goal is to harvest energy from the marine environment to operate [them],” says Lenny Tender, a research chemist at the Naval Research Laboratory (NRL) in Washington, D.C.
