We all know that Amazon is building its PrimeAir drone delivery service, so it makes sense for the company to build technology that can make the drone delivery sustainable.
Recently, Amazon patented a charging and docking mechanism on the roof of the car. This would extend the flying time of drones making deliveries 24-7. Since the company is also working on self-driven cars to make deliveries. The drones would be able to autonomously figure out which Amazon car is the closest for charging.
