Get to the feedin' tube

The days of small underground tubes delivering your groceries are closer than you know.

When we showed you the design study for the Urban Mole subterranean delivery system, we had no idea how much time and effort people have spent figuring out how to deliver small parcels through underground tubes.In the days after we wrote about the Urban Mole last week, our inbox filled with emails from people saying, essentially, “Hey! You oughtta check out my idea…” Of the proposals, the Cargo Tunnel really caught our attention. The guys behind it — a former Intel employee and a UC-Berkeley professor among them — say they’ve developed a miniature tunnel boring machine (TBM) that can create the network of necessary tunnels without disrupting life above ground.
