The comet is the gas station, and steam is the receipt: a kilometre-wide field of heater vents boiling a comet nucleus for water, forty-odd vapor jets all leaning one way, pipes converging on one landed tanker, and exactly one capped vent sitting cold with its crawler parked on it.
An artistic imagining, not real hardware: a scattered field of borehole heaters boiling a comet nucleus for water, every vent throwing a vapor jet that leans off the low sun at the left edge while a thin magenta manifold line gathers the yield into one landed tanker, its gauge eye burning at the end of the pipe. ESA's Rosetta mission found water ice and sun-driven vapor jets on comet 67P, the real physics this scene exaggerates; everything shown is speculation and no such hardware exists.Image: poweringspace.com.
