A Series of Tubes #
June 9th, 2008 | In Worth Considering
This idea, like all great ones, seems like something a seven-year-old dreamed up:
Dietrich Stein, of the Ruhr-University of Bochum, wants to free up the roads by diverting the Ruhr’s freight underground. If his plan succeeds, the road network at the surface will be duplicated by a system of tubes below, inhabited by small vehicles that steer themselves automatically from factories to shops or even to individual homes.
