Amazon has already started using drones to deliver products to its customers, albeit on a very small scale.
However, there’s one small problem with drone deliveries as it stands: launching drones from the ground and flying them to people’s houses requires a considerable amount of energy.
In order to get round this potential issue, Amazon is looking at storing products at altitude in huge floating airships — described by Amazon as “airborne fulfillment centers” — and a network of drones to essentially float items down to people.
In the abstract of the patent filing, Amazon writes: “As the UAVs descend, they can navigate horizontally toward a user specified delivery location using little to no power, other than to stabilize the UAV and/or guide the direction of descent.”
Amazon also writes in the patent: “Described is an airborne fulfillment center (“AFC”) and the use of unmanned aerial vehicles (‘UAV’) to deliver items from the AFC to users. For example, the AFC may be an airship that remains at a high altitude (e.g., 45,000 feet) and UAVs with ordered items may be deployed from the AFC to deliver ordered items to user designated delivery locations.”
