Flush to the Line

Power arrives crooked; it leaves flush to the line.

An artistic imagining, not real hardware. A ruled drawing in graphite line on a warm ivory field, built entirely from straight rules and circular arcs over a faint square construction grid that covers the page. At the right stands a relay spacecraft drawn in flat elevation: a short triangulated boom with a small equipment box slung beneath it, and four parabolic receiving dishes on slender struts, each a different size and each tilted to a different angle, one aimed up and off the top edge, two aimed out to the right, one aimed down toward the lower right. Into each dish runs a narrow bundle of three fine parallel rays that enters from beyond the frame and brightens as it nears the aperture. On the left face of the spacecraft is a tall transmitting plate divided into a grid of small ringed cells. From that plate a wide corridor of light runs dead horizontally across half the page, its upper and lower edges made of four close parallel rules that space apart as they move inward, its interior crossed by seven shallow arcs struck from the plate that widen apart as they travel. Where the corridor reaches the left edge, the heavy black curve of a planet's limb rises, ringed outside by a graded halo of fine arcs standing for the sun directly behind it. A rectangular receiving field of small ringed cells sits astride the limb where the corridor lands, its cells drawn darkest along the corridor's axis and fading above and below. The construction grid stops inside the corridor and inside the planet, so those two areas are bare paper and are the brightest things in the frame. Two thin page rules and one vertical rule frame the composition asymmetrically. Nothing is filled, and no text, lettering, numerals or insignia appear anywhere. The scale is diagrammatic rather than literal, and nothing shown exists.
An artistic imagining, rendered procedurally, of a power relay parked at the Earth-Sun L2 point: four aimed dishes catch beams that arrive out of the outer system at four different angles, and one flat transmitting plate hands the gathered power inward along a single perfectly straight corridor to a receiving field on Earth's backlit night limb. L2 is a real place about 1.5 million km beyond Earth on the anti-sun line, where the sun sits directly behind the planet and space telescopes are genuinely flown, and wireless power beaming has been demonstrated in orbit at small scale by the SSPD-1 MAPLE experiment in 2023; a relay of this size, and the scale drawn here, are speculation.
