One Rung Out

The spine is its own wiring diagram: two rails, five rungs, one rung held open, and the current takes the long way down.

An artistic imagining, not real hardware. A continuous tone illustration in warm earth browns. A tall lattice spine rises from a dusty cratered plain, leans a few degrees off vertical and runs out of the top of the frame: two round conductor rails of different diameters flank a darker climber mast, tied together by five horizontal decks and by diagonal bracing that zigzags on one side only. A small fierce sun sits low at the left, washing the horizon pale gold and throwing long shadows across the plain to the right. Pasted flat on top of this modelled world, with slightly wavering scissor cut edges and no shading whatsoever, is one unbroken red shape: it comes in at the upper right along the spar of a stepped solar wing, runs down both rails, crosses four of the five decks as flat rungs, drops at the foot of the spine, draws a plain rectangle around the low works at the lower left, and returns up the slimmer rail. At the middle deck the rung is blue instead of red and is visibly broken, a clean gap left where the circuit has been opened, with a wheeled breaker cabinet racked out to the left on its rails and two ribbed bushings standing on its lid. Flat yellow marks show what the power is for: a row of unequal lit windows and one tall lit doorway inside the red rectangle, and one small lit slot in the climber car parked in the track halfway up the spine. Machinery hangs off the spine at three unequal heights, a finned transformer high on the right, two horizontal breaker tanks of different sizes right of centre, and the racked out cabinet at the open rung. Low lit dust hangs around the anchor deck.
An artistic imagining of the power spine of a space elevator anchored on Ceres, not real or planned hardware. Current brought down from the counterweight arrays runs the length of two trunk conductors and out into the surface works, while one rung of the ladder has been isolated and its breaker racked out for work, and the rest of the bus keeps carrying.
