Underground Freight Networks 284
morphovar writes "The German Ruhr University of Bochum is conducting experiments with a large-scale model for an automated subterranean transport system. It would use unmanned electric vehicles on rails that travel in a network through pipelines with a diameter of 1.6 meters, up to distances of 150 kilometers. Sending cargo goods through underground pipelines is anything but new — see this scan of a 1929 magazine article about Chicago's underground freight tunnel network (more details). Translating this concept to the 21st century would be something like introducing email for things: you could order something on the Internet and pick it up through a trapdoor in your cellar the next morning."
