Advanced-basic systems
Relate Fresnel heat, mirrors, aqueduct filtration, and capillary lift.
These are prototype concepts that combine light, evaporation, condensation, passive pumping, filtration, ventilation, and relative measurement.
Solar water cycling
Fresnel-assisted underground evaporation gallery
A surface Fresnel lens or reflector warms a sealed non-combustible evaporation chamber while a cooler buried section condenses water.
Relative flow
- Sunlight warms a dark metal heat plate
- Warm vapor rises from a shallow source tray
- Vapor enters a cooler condensation coil or sloped glass channel
- Condensate drains to labeled non-potable storage
Where it fits: Demonstration-scale water recovery, humidity research, saline-water experiments, or greenhouse moisture balancing.
Caution: Fresnel lenses can start fires and injure eyes. Use shade shutters, metal/glass parts, and no unattended operation.
Fresnel + watered mirrors
Watered-mirror Fresnel passage light
A Fresnel collector feeds light onto a shallow water-film mirror or cooled reflective trough so underground passages receive softened moving light.
Relative flow
- Lens or light scoop remains above ground with manual shade shutter
- Light strikes a water-wetted reflective tray
- Secondary matte mirrors carry light down passage
- Diffuser panels spread light across walking and growing zones
- Drain returns warmed water to a labeled non-potable loop
Where it fits: Daytime passage lighting, underground greenhouse orientation, algae or shade-tolerant plant trials, and reduced electrical lighting demand.
Caution: Watered mirrors reduce harshness but do not remove fire, glare, eye, or overheating risks.
Charcoal filtration + aqueduct
Activated-charcoal aqueduct polishing bay
A slow underground aqueduct passes pre-settled water through gravel, sand, activated charcoal, and plant-root polishing cells before non-potable irrigation reuse.
Relative flow
- Settling chamber removes grit
- Gravel distributes flow
- Sand slows movement
- Activated charcoal adsorbs some odors and dissolved compounds
- Wetland-root bay and sampling port finish the polishing path
Where it fits: Improving smell, color, and some dissolved contaminants in irrigation-water experiments after sediment removal.
Caution: Activated charcoal is not a complete purifier and does not guarantee removal of pathogens, salts, heavy metals, pesticides, or all chemicals. Test water before edible-crop reuse.
Passive pumping + propagation
Capillary-action pumping wick bed
A lower reservoir feeds water upward through sand, clay, rope wick, or capillary matting so seedlings receive moisture without powered pumps.
Relative flow
- Covered reservoir sits below tray
- Wick or porous bed bridges water upward
- Root-zone medium receives slow moisture
- Overflow returns to mulch basin or inspection cup
Where it fits: Nursery benches, drought-buffered seed starts, underground propagation rooms, and low-energy moisture regulation.
Caution: Keep reservoirs covered and clean, avoid stagnant water, monitor salt buildup, and separate experimental water from potable systems.
Light + water + ventilation
Hybrid mirror-aqueduct cooling wall
A shaded water wall or aqueduct channel behind a diffused mirror path cools incoming air while providing reflected light.
Relative flow
- Low vent draws air over shaded wet surface
- Water trickles through mineral or ceramic media
- Mirror baffle reflects light while blocking glare
- High vent releases warm humid air
Where it fits: Hot-climate greenhouse cooling, humidity buffering, and passive ventilation research where drainage is reliable.
Caution: Prevent mold, algae, structural dampness, and water near electrical systems. Include cleanout access.
Refraction + mirrored sight
Central spire pothole refraction sight channels
A central vertical spire (light shaft) topped by a pothole or oculus gathers sky and area view, then refractive lenses and angled mirrors channel that view down separate sight channels, one to each individual rest space, so occupants can see a portion of sky and surroundings without windows in every wall.
Relative flow
- Oculus or pothole at spire top frames sky and area
- Refractive lens bends light/view into the shaft
- Angled mirrors split the channel toward separate branches
- Each branch terminates at a rest space with a small diffusing view-port
- Manual shutter lets each occupant dim or close their view
Where it fits: Orientation, wellbeing, reduced claustrophobia, dark-sky-compatible daylighting, and connection to weather/time of day in underground or windowless rest spaces.
Caution: Real refraction and mirrors cannot create a true sharp periscope image of a wide area from one small opening; expect softened, approximate views, glare, and heat. Keep beams diffuse, add shutters, and verify fire, water-infiltration, and emergency-egress code before any occupied installation.
