The Ring Lets Go

A season of patient trickle stands in rank, and when the ring lets go the grid itself steps out of register.

An artistic imagining, not real hardware. A flat, hard edged picture in ochre, umber and bone on a mid brown field, built on one tilted grid running from the lower left corner to the upper right. A long rail crosses the frame on that diagonal and nine boxy storage banks stand ranked along it, each drawn as a staircase of stacked courses with pale oblique tops. The five banks at the lower left are filled almost to their caps with saturated gold, and a small bone bar juts out beside each one at the height of its fill. The sixth bank is gold only to about half its height. A hard white staircase of light, flanked by amber and burnt orange staircases of decreasing width, leaves the top of that sixth bank and climbs away to the upper left in stepped treads and risers, ending against the lit underside of a large stepped dark structure cropped by the top edge. Past the sixth bank the rail and the banks jump out of alignment in whole step increments, the gaps between banks widen from narrow to very wide, and the last three banks are almost entirely dark with only a thin gold sliver left at their bases. Below the rail a second bus line runs parallel and about twenty five thin bright feeders rise from it into the rail, with two dark ruled panels cropped by the bottom left corner. A large planet limb fills the lower right, a dark brown body with olive continents and a broad pale lit edge. The whole picture is doubled twice by fainter offset copies of the machinery running off the top of the frame, and three large translucent sheets, one of them square to the frame rather than to the tilted grid, lie across everything. Nothing shown exists.
An artistic imagining, rendered procedurally, of a ring of capacitor banks in high Earth orbit: a comb of thin feeders charges the ranked banks slowly, their gold fills and bone index bars showing how full each one is, and the whole rank is caught at the instant the sixth bank lets go and throws a single hard staircase of current into the load. Capacitors really do trade energy density for the ability to be emptied far faster than a battery, which is why terrestrial pulsed power facilities charge banks slowly and dump them in microseconds, but no orbital ring of this kind exists or is planned.
