The Watt Census

A superconductor keeps no cut, so the pole's books can be kept in pictures: forty counted in on the light side, forty counted out into the dark.

An artistic imagining, not real hardware. Flat pictorial-statistics diagram on warm paper with a pale ruled module grid, drawn only in ultramarine, deep blue, gold, black and white with no shading or texture. A large blue ring circles a small black dot at the lunar pole; a pale blue half-disc covers its right side as the shadowed sector, holding four deep-blue crater discs, each with a single white dot at its centre and a straight blue bar tying it back to the ring. Sixty identical small white dots march evenly around the ring as current in transit, and forty-eight identical black squares stand outside it as pylons, none of them rotated to follow the curve. On the left, six identical gold-panelled collector stations sit on the sunlit rim, each connected to the ring by a straight blue bar and each trailing a horizontal row of identical gold discs counting its sunlight intake: five, seven, eight, eight, seven, five. A blue bus bar drops from the bottom of the ring, turns square twice, and runs down the right side into the lower half of the sheet, where five horizontal blue rails feed five rows of identical blue discs beside five black user pictograms, a domed habitat, a mine, a process plant, a rover and a dish, counting thirteen, ten, eight, five and four.
An artistic imagining, in the flat counted-pictogram language of Isotype, of a superconducting power ring circling the lunar pole and tying its sunlit rim collectors to users in permanent shadow. Forty units of sunlight are counted in on the rim and forty are counted back out to habitat, mine, plant, rovers and dish: the ring itself keeps nothing, so the census closes.
