As city streets grow more and more crowded, it is more difficult for delivery trucks to get through them. The solution is to deliver the packages through the sewers.

Yes, that network of tunnels designed to move human waste from our homes could be used to bring packages to our homes. All of this is possible with the proper application of robots.

Some researchers are working on inventing the Urban Mole. Instead of digging through the dirt, the Urban Mole is designed to carry packages such as signed documents, groceries, and Amazon.com orders. Of course, there are limits, and my source has said it can probably deliver nothing bigger than a shoebox.

Of course, I don’t know how good of a condition your packaged materials would be if they have just been swimming through sewage. Perhaps it will be required from every Urban Mole to take a shower before it knocks on the door.

Another problem that I forsee is what do you do when there is some sort of breakdown in the system? Do you send someone in the sewers to fix it? That’s one of those “dirty job, but someone has to do it” thing.

This is one concept gadget that I don’t think will ever be made, but you never know. I have seen I, Robot, and I believe that robot delivery people will be walking, not swimming.
