Prefab space capsule house -- mangrove research outpost A single steel cylinder sits on screw piles above the tidal roots, its curved shell pre-cut to accommodate a hatch that opens onto a suspended walkway. Inside, the tiny house container holds a water-salinity bench, specimen tanks, and a compact berth for the marine biologist, while the elevated design keeps gear dry during spring tides. The prefab space capsule house connects to a second module for microscope work, or stands alone as a solo observation post. When the breeding season shifts, unpin the piles, lift the pod, and relocate to the next estuary -- no root damage, just fins and data that follow the nursery grounds.
