The Blackwater Harp

A freestanding abyssal geothermal and dissolved-mineral collector with a porous, dramatic industrial silhouette. A low horseshoe bank of squat sealed pressure vessels sits on a flat dark-basalt platform, opening toward the front around a low round intake bell. Five hollow tusk-shaped support frames rise from the rear arc, increasing in height from left to right; the tallest is about three times the vessel bank height. Each tusk is an elongated open arch, thick at its two anchored feet, tapering into a continuous backward-curved crown; all crowns bend toward the rear along the same axis. Three to five slender rigid bronze condenser pipes hang vertically within each open arch and connect to the lower manifold, clearly plumbing rather than musical strings. Tusk frames are bronze structure clad in overlapping charcoal ceramic armor. Low vessels have mismatched curved barnacle-white ceramic jackets, exposed green-bronze straps and individually accessible front locks. Narrow fixed rear service gantries connect frame feet, supported on bronze brackets; paired external pipes descend down the back of each frame to the manifold. Left side exposes a repaired ceramic panel and a shell-fragment hatch hood; right side has two short outlet nozzles and a removable cylindrical filter housing. Yellow phosphorescent slivers mark latches only; tiny cyan inspection lenses mark fluid routes. The top view shows the horseshoe footprint and five separate rearward arch crowns with open gaps between them. Coral-free working equipment, dark structural blades and abundant negative space; no sailcloth, no solid curtain across the tubes, no floating parts.
