ABSTRACT:
A pipeline capsule transportation apparatus and method for transporting capsules in a continuous linked train, including an elongated pipeline having a plurality of sets of upstream and downstream pipeline locations, a plurality of energy transfer stations downstream of the various downstream pipeline locations, each transfer station comprising an elongated enclosure which surrounds a length of pipeline and is in fluid communication with the length of pipeline, the enclosure having an inner diameter larger than that of the pipeline, station pumps for withdrawing fluid from a downstream location of each station and pumping the fluid into an upstream location of each station to provide downstream fluid flow along the enclosure of each station for propelling capsules passing through the length of pipeline in such enclosure, and control pumps for controlling the velocity of fluids between each set of upstream and downstream pipeline locations during use for the pressure to be less at each upstream pipline location than at the next succeeding downstream location, and for the pressure at each downstream station location to be greater than the pressure at the preceding upstream pipeline location for such station.
