Drawings

Dimensioned drawings for the bench build, then schematics of the full system on Mars. Millimetres throughout, not to scale on screen.

RWL-001 and RWL-004 are also in the 3D model.

RWL-001 — Filtration column

Vertical section through the column: four media layers, the water charge above them, the screen and valve below. The media schedule gives depth, volume and an indicative mass for each layer.

Vertical section of the filtration column showing four media layers with dimensions — RWL-001 REV EFill by depth, not by mass. Layer depths are the specification; masses depend on the bore of the pipe actually used.open full size

RWL-002 — Photometric rig

Plan view of the photographic setup used to measure turbidity, plus a diagram of the frame the camera should produce. Distances matter less than the fact that nothing moves once a session starts.

Plan view of the photographic rig with camera, sample jar, target card and white reference card — RWL-002 REV AThe white card cancels exposure differences between shots. Without it, a cloudier sample and a darker room are indistinguishable.open full size

RWL-003 — System process flow

All three stages inside the pressurised habitat, with every stream between them: regolith, water, char, heat and gas. Rates are for six crew at an early base, from the sizing on the Mars page.

Process flow diagram linking the bioreactor, filter modules, pyrolysis retort, main water processor and crew — RWL-003 REV BGrey dashed streams are proposed, not demonstrated. The oxygen from Stage 1 is not drawn as a product because the bacteria respire it.open full size

RWL-004 — Habitat integration

Where each stage sits in a habitat module. Regolith stays in a dirty zone behind a sealed bulkhead, and cartridges cross it already sealed.

Plan schematic of a habitat module split into dirty, service, wet and crew zones — RWL-004 REV AThe retort and the bioreactor share the bulkhead so the retort's heat reaches the reactor jacket. Zone sizes are not derived.open full size
