This also kind of seems analogous to the electron Cooper pairs moving through a superconductor... As one electron moves down into a trout, the other moves up into a peak, and because of the push/pull balancing interaction of their paired up connection, energy is not dissipated (as heat), and in-turn no additional energy is required for propagation... They just keep on moving.
