A group of scientists and engineers working out of Imperial College London have gone ahead and devised an ingenious, wirelessly powered drone that is capable of being juiced up when it's flying without the need for a tether or other physical connection.
This particular drone takes the format of a compact quadcopter, and is equipped with a copper coil and manipulated electronics. There's also a separate transmission platform that is hooked up to a power source and its own copper coil. When the drone is near the platform, it latches onto its magnetic field in order to receive an electrical current.
Ultimately, this wirelessly powered drone could be used in order to create flying power sources, something that could result in the introduction of wirelessly charging drone ecosystems that could be of use in complicated environments.
