Amazon's fulfillment centers are gargantuan facilities. They're sprawling, 1 million-square-foot buildings that make Super Walmarts look like tiny houses, which means they're not exactly suitable for neighborhoods that are close to customers in dense urban areas. Since they're so far from most of Amazon's customers, these buildings pose a real logistical challenge for the company's plans to deliver packages via autonomous drones with a short range.
But while 1 million square feet is a lot when it's laid out in a single story, it's only about a 30-story skyscraper. Which brings us to Amazon's latest filed patent: A "multi-level fulfillment center for unmanned vehicles." That's right, it's a drone tower.
