DJI and UC Berkeley Students Team Up to Find UAV Power Solution What do you see as potential applications for your design? A drone that has unlimited flight and a cabled connection to the power grid opens up many possibilities. The quad could replace temporary truss towers to reach altitude and may be used as a temporary WiFi or cell tower, loudspeaker mount, light tower, or small weather station. The drone will now be able to survey areas over long periods of time since power is no longer limited to the time that a single battery can last. The tether could allow for search and rescue operations or even media coverage of sports games or music performances.
