Drones could become useful for surveillance and remote monitoring in many industries, and perhaps one day will even ferry the latest Amazon order to your front door. But there’s one big limiting factor: drones can stay in the air for only so long on a charge [technologyreview.com].

Not the latest model developed by the Boston-based drone maker CyPhy Works, though. Called Parc, the drone can perform aerial surveillance indefinitely, using a “microfilament” that transmits power and data. Of course the fact that it’s tethered means the drone can’t travel very far. CyPhy Works expects it to be used for reconnaissance or as a communications relay.

Wind?
