Pneumatic Tubes: Transportation of the Past... And Future?

The video explores the concept of futuristic travel using pneumatic tubes, a technology that has existed since the 19th century. Initially used for mail and small items, pneumatic tubes operate by creating a partial vacuum to move canisters. Despite their efficiency, they were limited by the need for complex networks. The video also discusses the potential for human transport using similar principles, as seen in historical experiments and modern designs like the Hyperloop, which combine pneumatic concepts with magnetic levitation.
