Army scientists could use urine to charge 3D printed drones that eat themselves

Scientists at the U.S. Army Research Laboratory have discovered that a recently engineered aluminum nano-powder can rapidly produce hydrogen when mixed with urine. The powder could be used to make 3D printed robots that “feed off their own structures” and self-destruct after missions. ARL’s Anthony J. Roberts uses urine to set off a chemical reaction […]
