Ice Reads Left to Right

Ice on the left, thrust on the right, one lit blue line between.

An artistic imagining, not real hardware. A flat-plane signage board on a pale near-white square ruled by a faint blue-grey module grid, with the sheet's own construction geometry — square diagonals, an inscribed diamond, an inscribed circle — left faintly visible. At lower left a pale blue mass of water ice is cut into benches whose risers all fall at exactly forty-five degrees; a shaft with an A-frame headframe drops into it and three horizontal galleries with small square chambers run out sideways, and a small figure built from bars with a plain circle head stands on the top bench for scale. A dark cutter machine with a toothed disc bites the second bench and a loader digs the third; a forty-five degree conveyor carries square ice blocks up to a chamfered hopper, which feeds a vessel half full of pale blue meltwater warmed by orange heater bars. A cyan distribution bar drops water into a five-by-six matrix of identical square electrolysis cells, each holding a disc and a rising chain of two small bubbles; the disc colour steps across the five columns through a systematic blue spectrum from palest ice to deepest indigo. A dark indigo pipe network collects hydrogen below the matrix, climbs a riser, runs level along the top and couples to a tall silver tanker standing at right, whose vertical gauge is filled about two thirds with bright blue; a light green header carries oxygen into a green-filled tank, and a second blue tank stands between. An orange power bus runs from a plain orange source disc and a stack of five parallel flux rules, past four tilted collector panels, down the left side of the plant with a rung into every cell row. A twelve-square colour key sits on the baseline in the lower margin. Every edge is horizontal, vertical, or forty-five degrees; flat fills only, no gradients. Purely procedural geometry; no text, no insignia, no real hardware depicted, and nothing shown exists.
An artistic imagining, rendered procedurally, of a Ceres water-ice mine and its electrolysis plant drawn as a single wordless signage board — benches, a shaft and galleries cut into the ice at left, a conveyor lifting blocks to a melter, a matrix of cells splitting the meltwater, and one lit blue line carrying hydrogen into the depot tanks and the waiting tanker. NASA's Dawn mission found water ice within about a metre of Ceres' surface at mid-to-high latitudes and sunlight there is roughly an eighth as strong as at Earth, which is why the collectors are so wide, but no such mine or plant exists.
