Suppose we discovered something like this:
The "moving walkways" pass close to local stars fairly far from their suns. Each "walkway" consists of two columns of dust moving at a significant portion of the speed of light. Each is 400m in diameter, passing by our solar system on a useful trajectory toward nearby stars, above & parallel the ecliptic.
Like outbound & inbound subway tunnels. (Though, to step in these tunnels would be death)
How could we exploit the fast predictable dust highways?

@futurebird So like relativistic Aldrin Cyclers, plus mass?
Setting aside transport, it seems like there's something to be done with the trade-off between relativistic speed and stable conductive properties.
