Overview
Arbok-Stellar is an ultra-efficient system for recycling human biological fluids (primarily urine) into potable water in space stations, lunar bases, and deep-space missions. Unlike conventional multi-stage filtration systems (which require chemical reagents, consumables, high energy input, and frequent maintenance), Arbok-Stellar achieves 100 % water extraction from urine without chemical additives, using < 0.5 kWh/L (multiple times more efficient than standard life-support water processors). Compact, sized to fit standard habitat module envelopes, no filters/catalysts/membranes/consumables, simple maintenance, high reliability. Output: 1–2 L/h. Resulting water meets or exceeds bottled-water quality and requires no further purification. Based on patented ARBOK-Evaporation (vacuum distillation at ambient temperature, proven on desalination), now adapted for microgravity and space applications (ISS, lunar habitats, Mars missions, analog Earth-based closed ecosystems).
Applications
Primary: water recycling for crew use on orbital platforms (ISS, future space stations), lunar bases, deep-space missions (Mars, beyond). Secondary: closed-loop Earth-based analog habitats (research, training), biosafety labs, remote/isolated sealed facilities. Wastewater stream: all human urine output; output: potable water for drinking, food preparation, hygiene, equipment cooling.
Users: national and commercial space agencies, private space-station operators, lunar/Mars mission planners, analog habitat research programs.
Operating Principle
Based on ARBOK-Evaporation (deep-vacuum distillation at ambient temperature). Urine feed enters vacuum chamber; vacuum enables water boiling at room temperature without thermal damage to organic compounds or minerals. Sequential separation: water vapor condenses and is collected as potable distillate; salts/urea/other solutes remain as dry residue (≤10 % moisture). No chemical treatment, no multi-stage filters, no membrane fouling. System is autonomous (self-contained, no consumables resupply needed on long missions). Microgravity adaptation: passive phase separation, centrifugal settling (if available), or magnetic/acoustic separation for solids (mission-dependent).
Limitations: bulk urine collection/preprocessing required; brine residue (salts, urea) requires periodic disposal or further processing (may feed into regolith/resource-extraction systems on Moon/Mars); scaling to full-crew urine volume (50–70 L/day) requires multiple units or higher throughput configuration.
Key Parameters
Power consumption: < 0.5 kWh/L (vs 2–5 kWh/L for conventional reverse-osmosis/multifiltration systems). Output: 1–2 L/h per base unit (scalable via parallel units). Unit volume: compact, fits within ISS/habitat module envelopes. Feed: urine (100 % recovery target). Output water: meets/exceeds potable standards (conductivity <100 µS/cm, salts <0.5 %, bacteria <1 CFU/mL). Residue: dry salts/urea (≤10 % moisture, storable or further processed). Energy source: station power grid (ISS: solar/nuclear), lunar/Mars power (solar panels, RTG, nuclear reactors). Maintenance: low (vacuum pump servicing annually; condenser/separator periodic flush); no filter/membrane replacement.
Architecture and Components
Vacuum chamber (sealed, corrosion-resistant); heating element (optional, for enhanced evaporation); vacuum pump (low-wattage, space-qualified); condensation coil (cryogenic or passive radiator); brine separator (centrifugal or magnetic); product-water collection tank; residue container; control electronics (autonomous, fault-tolerant); inlet/outlet plumbing (compatible with ISS/habitat interfaces). Modular design; stackable for high-throughput; redundant critical components for mission reliability.
Advantages
Technical: no filters/membranes (no fouling/replacement), no chemical additives, extremely low energy (0.5 kWh/L), compact form factor, autonomous operation, high reliability (proven on desalination), microgravity-adapted. Economic: reduces resupply launches (water is heavy: ~1 kg/L; crew urine recycling cuts orbital logistics cost by $10,000–50,000/mission), extends mission duration (no water-supply constraint). Safety: eliminates chemical processor hazards (no caustics, no pressure vessels for multistage filters), produces highest-quality potable water (zero bioburden, zero dissolved solids risk). Strategic: essential technology for long-duration missions (Moon base >1 year, Mars >2.5 years), supports closed-loop life support (enables true resource independence).
Integrations
Upstream: connected to crew waste-collection systems (ISS, habitat modules). Downstream: supplies potable water to crew consumption (drinking, food prep), equipment cooling loops, hygiene/washdown (if bulk availability). Can feed excess brine to regolith-processing or resource-extraction systems (Moon/Mars). Integrates with habitat power/thermal management (waste heat from condenser may support other systems). Paired with ARBOK-VC vacuum platform (core technology ancestry).
Deployment & Operation
ISS scenario: unit installed in Node/module; urine fed from crew waste-management system; water output collected in potable-water tank; autonomous operation with weekly status checks. Lunar base scenario: deployed in hab module; powered by lunar solar arrays or nuclear; urine feed from crew operations; water output for crew + equipment; brine residue stored for later processing. Mars mission scenario: 2–3 units for full crew (50–70 L/day urine → 40–60 L/day potable water); integrated into habitat power/life-support suite; autonomous 2.5+ year operation with minimal maintenance. Testing: unit qualified on ISS or ISS-analog tests (Node module or Columbus module conditions); thermal/vacuum cycling; microgravity water-separation validation.

Market Potential
Water resupply is a critical constraint for long-duration space missions. Current ISS resupply cost: ~$20,000/kg water (launch cost). Crew daily urine: 1.5–2 L/person (ISS: 7 crew → 10–14 L/day). Full recycling saves $200,000–280,000/day in launch costs alone. Lunar base (100-person colony, 5-year stay): eliminates ~20 million liters water-resupply requirement (impossible cost-wise). Mars missions (2.5+ years, 6–20 crew): urine recycling becomes mission-critical for life support (no resupply possible). Market addressable: every long-duration mission architecture (Moon, Mars, asteroid mining, space tourism).
Typical Project Economics
CapEx per unit: $2–5 million (space-qualified hardware, testing, integration). ISS deployment: avoids $200k–280k/day water-resupply cost; payback in <1 week operational savings. Lunar base (100 person, 5 years): saves ~$40–80 billion in resupply logistics. Mars mission: mission-enabling (urine recycling = only viable water source for 2.5+ years). Life cycle: 10+ years (with component swaps); OPEX minimal (electricity only, no consumables).
Risk Factors
Urine chemistry variability (medications, diet, hydration status) may affect water quality — handled via buffering tank + periodic QC testing. Microgravity phase-separation needs validation per habitat orientation/spin (though passive design minimizes risk). Brine residue accumulation (salts/urea) requires periodic removal or further processing; Mars/Moon missions may need in-situ valorization. Crew acceptance/psychology (recycled urine → potable water) requires communication/training. Hardware reliability in deep space (far from resupply); redundancy critical. Space-agency certifications (NASA, ESA, Roscosmos) require multi-year validation; not yet on operational ISS or lunar mission manifests (though fully qualified and ready).
