The world's oceans are large, and only its surface is used, while the depths are empty. And the same can be said about any more or less large body of water near any settlement. And the global e-commerce giant is running out of potential for land-based storage. Putting it all together and getting a project of an underwater automated warehouse.
The patent application came to the attention of the press in the middle of this summer. Amazon does not pretend to exploit a specific lake or sea; any pool, even a puddle, is suitable for arranging a warehouse, if it is of decent depth. The main thing is the ability to fill the empty underwater space with sealed containers with a payload.
Each container is equipped with an acoustic signal receiver with an individual code, so you just need to “shout correctly” into the water to receive the command to ascend. For this, compressed air is used in a cylinder and inflatable bags on the roof of the container. Moreover, the gas does not come in anyhow - the bags are inflated in such an order that the structure floats in the right direction and floats to the shore itself.
From the explanatory note to the patent application, it is not clear who will control the process of drowning and lifting containers, a robot or a person. On the other hand, it also describes a system of tunnels for an underwater warehouse, through which containers can immediately go to the desired addressee. It's not that hard to dig a large reservoir underneath the city, with a network of pipelines to get goods to stores without driving trucks through the streets, is it?
Is there a need for such innovation? Yes, and another one - forecasts regarding the development of Amazon's trading business draw the need for warehouses with an area of millions of square meters, where a warehouse robot will pass thousands of kilometers a day with containers. And under water, all this can be realized with practically no energy consumption, only due to the Archimedes law.
