Hungry? Better turn on your linear induction motor and send a metal capsule through an underground polyethylene tube to retrieve some groceries.
That's the vision of Foodtubes, a UK program that seeks to reduce carbon emissions by building a pipeline-capsule system to deliver food and freight. A series of tubes could ferry 6-foot-long metal bins among neighborhoods, entire cities or even to different countries, moving goods at 60 mph using linear induction motors and intelligent routing software.
If you live in a big city, you probably know how dangerous bike messengers can be, suicidally zipping in and out of traffic at high speeds and smacking pedestrians in the head with their bike locks. But in a crowded city, if you want a package delivered as soon as possible, they tend to be the quickest option.
If designer Phillip Hermes has his way, though, your packages might be delivered by scurrying underground robots instead. Via the sewer.
