If water, sewage, gas and oil can be transported through underground pipelines, why not consumer goods as well?
Some Western European countries are getting serious about transporting consumer goods through automated subterranean networks – introducing a fifth transport mode next to road, rail, air and water. This rare combination of low-tech sense and high-tech knowledge could lead to a further economic growth without destroying the environment and the quality of life. Super fast underground cargo transport is a favourite subject of futurologists. Yet, the key to the feasibility of the proposed systems is their very low but constant speed.
