It was the second day of a 3-day-long tech demonstration at the David Taylor Model Basin at the Naval Surface Warfare Center in Bethesda, MD, where attendees had gathered to stand around in the dark to look at something they mostly couldn”t see. It was a long-range, free-space power beaming system—the first of its kind.
Even as drone technology advances, power constraints limit the amount of equipment unmanned systems can carry, as well as the time they can stay in the air. Some drone systems, like the Persistent Aerial Reconnaissance and Communications drone from CyPhy Works, deliver power through a tether to keep a small drone aloft for an entire
The Defense Advanced Research Projects Agency (DARPA) arguably develops some of the most technologically advanced systems known to man, and its latest endeavor certainly continues that tradition. While the agency’s Stand-off Ubiquitous Power/Energy Replenishment – Power Beaming Demo (SUPER PBD) program definitely has a lengthy title, it actually has the very essence of protraction at
