Unmanned aerial vehicles energized by power lines

A method comprising:

• performing, by an unmanned aerial vehicle (UAV), an unmanned aerial operation, wherein:
• a charging mechanism is operatively coupled to a body of the UAV, the charging mechanism configured to connect to power transmission lines deployed near an air space in which the UAV is performing the unmanned aerial operation, the charging mechanism configured to draw power from the power transmission lines to power the unmanned aerial operation, and
• an electric circuit is onboard the UAV, the electric circuit configured to generate, based on the power drawn from the power transmission lines, charging currents to power the unmanned aerial operation;
• while performing the unmanned aerial operation, drawing, by the charging mechanism and by continuous contact with the power transmission lines, the power;
• and
• charging, by the electric circuit and using the drawn power, the UAV to continue to perform the unmanned aerial operation.
