The Heat Must Fall

Everything the station keeps is dark and still; only the heat may leave — torn off in red and let fall into the cloud sea.

An artistic imagining rendered as a flat cut-paper style poster on a pale sulfur-cream field: a dark charcoal aerostat — teardrop balloon envelope, thin spine, small hexagonal gondola, and a ladder of horizontal radiator slats — hangs in the exact center of the square, backed by a pale haze disc. Half the slats are bright vermilion with torn edges, and torn red scraps tumble away from the stack in two arcing trails, rotating as they fall toward the bottom of the frame, where an enormous hand-torn band of crimson and vermilion paper — the shed heat — spreads across layered tan cloud bands.
An artistic imagining, not existing hardware: an aerostat station adrift in Venus's temperate cloud deck, where generating power is the easy half — every watt used must eventually be thrown away as heat. The station keeps its dark, quiet shape; only the heat leaves, torn off in red strips and let fall into the cloud sea. Image: poweringspace.com. Artistic imagining.
