WATER & POWER LAB
Filter, cool, synchronize
Water remediation planning, soil structure, passive cooling, human power, and offline device rings.
Slow-sand & jar-test planning
Hydraulic loading: 120 L/h/m² · maturation: 21 days
Example jar dose at 100 L / 20 mg/L: 2.00 g
Never treat drinking water from this estimate alone. Pathogen testing, approved materials, flow control, maintenance, and health-authority guidance are required.
Soil compaction & porosity
Bulk density: 1.60 g/cm³ · porosity: 39.6%
Drop-cone and accelerometer readings require calibrated probes and site-specific correlation.
Earth tubes & evaporative cooling
EAHE example velocity: 1.59 m/s · burial: 1.5 m · drain: required
Evaporative depression estimate: 10.0°C
Condensation, mold, radon, food safety, air quality, and drainage require design review.
Treadle, pedal & flywheel
Mechanical input: 88 W · example flywheel inertia (10 kg / 0.3 m): 0.90 kg·m²
Human-power ergonomics, guarding, overspeed, pinch points, and alternator or tool matching require review.
CRDT & ultrasonic peer ring
CRDT: Automerge / Yjs · offline merge: yes · conflict-free: yes
Ultrasonic discovery: short-range · encrypted payload · consent required · background loop disabled
Stage local sync-ring review
