Abstract
In accordance with a preferred embodiment, a charging station for charging of a UAV within a vicinity of powerlines includes an interface for electric coupling with the UAV for charging of a rechargeable battery of the UAV; a power supply having first and second electrodes separated and electrically insulated from each other for enabling a differential in voltage at the first and second electrodes resulting from a differential in electric field strength experienced at the first and second electrodes when within the vicinity of the powerlines; and electrical components electrically connected with the first and second electrodes and configured to establish a circuit with the rechargeable battery of the UAV when electronically coupled with the interface. The differential in voltage between the first and second electrodes causes electric current to flow through the electric circuit for charging the battery of the UAV.
