This is incredibly impractical, and no way this is economically feasible for home delivery of goods. This might be somehow practical for moving large quantities of highly valuable items (think hospitals transferring drugsor blood/plasma) over predictable paths regularly in a large, urban area, but the need for that must be relatively infrequent to how much it would cost to maintain a system as described here.
If robots are also building the tunnels it could be economically feasible 🤷
I mean, it depends on how deep they go and the type of soil/dirt they need to go through. I don’t know where this town is (too lazy to research that right now… It’s New Year’s Day, give me a break LOL) but much of Georgia is loose, iron-rich (very red! Like digging a hole out of rust) dirt/sand (the awful-feeling large grain kind) like 20-30ft deep. It’s easy to dig but hard to make a stable tunnel through (it’d just collapse).
If they are just shoving a thin steel “tube” (rectangular like the picture in the article) into the ground and forcing the dirt out (e.g. blow it out with air) that could be very cheap. It’d be like operating a really wide Ditch Witch.
