Ochemír Station: The first thing to notice when you board this massive skyfarm cylinder, parked in the Eliéra-Elarion L4 point, is the humidity. It’s downright wet. (A local fashion outlet, Ochemír Silks, offers a complimentary change of clothing to visitors, who are heartily recommended to take up the offer.) From docks and locks, through station control and the habitation sector, and even the factory torus, you can expect to feel moist, and see condensation.

It turns out that it’s very hard to avoid that, short of using completely separated life-support systems and internal airlocks, if you want to put a swamp in a space station.

For that is the purpose of Ochemír: as the leading supplier of dyanail and mahardyanail products to habs across the Orbital-Seléne Alliance and beyond, the main body of the station is an eight-mile cylinder whose floor is covered with shallow water and the finest synthetic mud, painstakingly crafted from selenic regolith and periodically refreshed with biowaste again imported from across the OSA. And that means entirely covered – even the windows, albeit the wet windows are covered in clear ponds, surprising visitors occasionally with the giant shadow of a koi swimming past, sun-side.

Of course, within the cylinder the station’s own products are widely used; paths of mahardynail separate the individual groves and towers of it hold sensors and cameras; water is recycled and special nutrients are added through pipes likewise; dyanail shacks house robot hotels and local facility nodes; and even the harvesting and maintenance drones run on dyanail rails.

Meanwhile, the factory torus processes the ongoing perpetual harvest into all manner of products: raw wood, laminate, bioplastic, ethanol, charcoal, and other carbochemicals, foodstuffs, paper, dyanail silk and raw fiber, and myriad hand-crafted products.

A fascinating visit for anyone interested in industrial ecology, wet-phase life support engineering and construction, spacer history, or merely unusual habitat designs.
