An electromagnetic wave gun that disables drones by disrupting their controls, causing them to safely land in place or return to whence they came, could provide drone-riddled San Francisco with a solution to a new but pesky problem.

Of course, the device, the Battelle DroneDefender, about which the Navy Times had the trade-show intel and Gizmodo ran an item today, is currently approved for military use only. As of now, the Department of Homeland Security and the Department of Defense reportedly have an arsenal of about 100 of them.

But if and when these drone-zappers become commercially available, it's only a matter of time before somebody declares open season on San Francisco's popular backyard-variety commercial drones. And while you can't fly your drones above the Golden Gate Bridge any more, people don't seem to stop. Just to be safe, maybe we put somebody up there with a DroneDefender: Any volunteers?
