The Oasis Platform
MODULAR VACUUM FLASH DISTILLATION
Classification: Plausibly Engineerable
Scientific Basis: Established (vacuum flash evaporation, phase transition thermodynamics)
Key Dependencies: DLC condenser coatings at production scale (C-Forge CVD), Vapor Vacuum UHV chamber fabrication, heat recovery efficiency at 100–400 Hz cycle rates
The Oasis is a modular water purification system that separates dissolved solids from water using rapid vacuum flash evaporation. Feedwater enters a low-pressure chamber where it vaporizes at room temperature, leaves contaminants behind in the liquid phase, and recondenses on diamond-coated surfaces. The output is potable water and dry salt. No membranes, no chemical pretreatment, no liquid brine discharge.
Operating Principle
Water at 20–30°C is injected into a radial expansion chamber held at 10–25 torr by Vapor Vacuum pumping systems. At this pressure, water's saturation temperature drops below the feedwater temperature, causing instantaneous surface evaporation. The vapor propagates radially outward to DLC-coated condenser surfaces where it recondenses. Latent heat released during condensation is recovered and returned to the incoming feedwater stream via a counterflow heat exchanger.
Specifications
Subsystem Architecture
The Oasis integrates three core subsystems, each documented separately:
Radial Expansion Chamber — The flash evaporation vessel. Feedwater enters through a central nozzle and expands radially into the vacuum volume. Chamber geometry determines flash rate and vapor distribution.
Diamond Condensation System — DLC-coated copper surfaces that recondense water vapor. Diamond's thermal conductivity (five times copper) enables the rapid heat removal needed for high-frequency cycling.
V8 Radial Chamber Array — Eight-chamber parallel configuration for throughput scaling. Staggered firing at 200 Hz per chamber yields continuous output.
Cross-Division Dependencies
REQUIRES: UHV-class chamber fabrication and pumping from Vapor Vacuum — 10–25 torr chamber pressure must be sustained against continuous feedwater injection
REQUIRES: DLC condenser coatings from C-Forge (Metallic Sciences) — diamond’s 2,200 W/m·K thermal conductivity enables high-frequency condensation cycling
REQUIRES: Compact thermal power from Stellar Furnace — off-grid deployment needs self-contained power at 3–5 kWh/m³ processing rate
ENABLES: Potable water supply for MK-Oasis (the Foundation) — the humanitarian deployment container depends on Oasis for water generation
The Oasis requires Vapor Vacuum UHV-class chamber fabrication and pumping systems. Large-scale deployment pairs with Stellar Furnace compact thermal power modules for off-grid operation. DLC condenser coatings are manufactured by the Metallic Sciences C-Forge CVD diamond growth facility.
Deployment Configurations

Open Unknowns
- DLC condenser surface fouling rate under real-world feedwater conditions (high TDS, biological contamination) has not been characterized at 100–400 Hz cycle frequencies.
- Heat recovery efficiency of the counterflow exchanger at the target 3–5 kWh/m³ is modeled but not validated in a physical prototype.
- Scaling behavior of the V8 array — whether eight chambers firing in stagger produce continuous output without pressure cross-talk — is undemonstrated.
