worldtubes
Worldtubes are a speculative concept for a global transportation network. The idea proposes a system of vacuum-sealed tubes through which passenger and cargo pods could travel at extremely high speeds, potentially approaching supersonic velocities. These tubes would be constructed either above ground on pylons or underground, creating a protected environment for transit.
The primary advantage of a worldtube system would be the dramatic reduction in travel times between distant
While the concept has been explored in various forms of science fiction and by some futurists, the
