U.S. Army scientists and engineers recently designed an aluminum nanomaterial that produces high amounts of energy when it comes in contact with water, or any liquid containing water. Since the nanomaterial powder has the potential to be 3-D printed, researchers envision future air and ground robots that can feed off of their very structures and self-destruct after mission completion. Another possible application of the discovery that may help future soldiers is the potential to recharge mobile devices for recon teams.
Fuel Cell Technology
Ion Tiger, an unmanned aerial vehicle (UAV) research program at the Naval Research Laboratory, is merging UAV technology and fuel cell systems that are more efficient and reduce noise. An Office of Naval Research-sponsored program, the Ion Tiger UAV tests a hydrogen-powered fuel cell design that has more endurance in flight distance and payload weight than battery-powered designs. The UAV also features a low heat signature and no emissions.
