This week, the United States of Boeing by United States trademark and Patent Office (USPTO) has granted a "UAV for the air charge" of new patents.

This patented invention people-James Childress and John Viniotis, mentioned in the document of UAV equipped with rope, can hover in the air, connected with the power supply station on the ground and charge. As envisaged in the patent, charging set can be very flexible and can either stand on the ground or standing in the ocean-going ships, and can even stand on top of the moving car. In this design, as long as the flight is charging, drones can never fly continuously, so as to improve the efficiency and effectiveness of UAV flight. Assuming, of course, is the arrangement of charging must be dense enough.

Need to use unmanned aerial vehicles for the delivery of e-commerce and logistics enterprises, which can allow them to significantly alleviate the worry of unmanned aerial vehicles may run out of power. Of course, Boeing this system, still cannot scale to achieve in the short term, because it requires deploying large numbers of unmanned aerial vehicle charging stations in the city.
