AERIAL STATION POWER TETHER WITH UNIPOLAR CURRENT FLOW
Inventors: Daniel Ludois
A UW researcher has developed a new power tether for aerial devices, such as balloons or drones, that uses as few as one conductor, providing a ground return by capacitive coupling between the aerial device and a ground plane at a base station. Using high-frequency, high-voltage power allows significant power transfer through the low capacitance between the aerial station and the ground minimizing the necessary current flow.
New tethered wire system. Apps such as tethered drones, tethered aerial platforms including aerial wind turbines or solar panels.
Lighter wire allowing for longer tether wires, and increased efficiency.
