AtmosPouch

A solar-assisted emergency device concept that pulls water vapor from humid air, condenses it, treats the collected water, verifies operating conditions and fills a sealed pouch.

INVENTED / UNVERIFIED Prototype: NOT BUILT Water validation: PENDING Energy validation: PENDING

Evidence boundary: AtmosPouch is not a certified drinking-water device. Output depends strongly on temperature and humidity, and no potable-water, production-rate, efficiency or field-readiness claim exists until independently measured and reviewed.

01 · System architecture

Capture, treat, verify and package

Air intake Screened airflow path with temperature, humidity and flow sensing. Measure source state
Condensation Refrigeration/dehumidification stage sized from measured dew point and expected water yield. Measure energy per liter
Collection Closed food-contact drainage and reservoir designed to limit recontamination. Sanitation review
Treatment Sediment and activated-carbon stages followed by a validated disinfection process appropriate to the actual hazards. Water engineer
Verification Flow, temperature, conductivity/turbidity where appropriate, filter-life, UV status and sample records. Independent lab tests
Pouch filling Clean, controlled fill path using compatible sealed pouches and traceable batch records. Packaging review

02 · Power module

Solar-battery planning build

Solar array 400–600 W Battery 12/24 V LiFePO₄, 1–1.5 kWh Charge control MPPT with PV disconnect AC conversion 600–1,000 W pure sine DC distribution Fused fan, pump, sensors and controls Design rule Net yield must include all parasitic loads

03 · Energy flow

Every watt is accounted for

  1. Solar input Measure irradiance and electrical energy entering storage.
  2. Stored energy Track battery state and conversion losses.
  3. Condensation load Measure compressor, fan and defrost consumption.
  4. Treatment load Measure pumps, sensors and disinfection energy.
  5. Net result Report liters collected and treated per measured kWh.

04 · Prototype sequence

Build the measurement rig before the field enclosure

1

Power bench

Validate protected solar, battery, DC and inverter paths with dummy loads.

Gate: stable output and verified protection
2

Condensation bench

Measure hourly water yield across controlled humidity and temperature points.

Gate: repeatable liters-per-kWh curve
3

Sanitary collection loop

Add closed drainage, cleanable reservoir and treatment train.

Gate: materials and sanitation review
4

Instrumented pouch filler

Fill sample pouches under a documented cleaning and sampling procedure.

Gate: seal integrity and contamination controls
5

Integrated enclosure

Combine subsystems only after bench measurements support the thermal and electrical design.

Gate: endurance, fault and restart tests
6

Independent validation

Use a qualified laboratory and relevant authorities before any drinking-water use.

Gate: documented approval for intended use

05 · First build list

Functional component categories

  • Commercial dehumidifier or refrigeration test module
  • Temperature, relative-humidity and dew-point sensing
  • True-energy meter for condenser and parasitic loads
  • LiFePO₄ battery with BMS, fuses and disconnects
  • MPPT controller, PV-rated wiring and protected enclosure
  • Food-contact reservoir, tubing, fittings and sample ports
  • Sediment and activated-carbon filter housings
  • Professionally reviewed disinfection stage and interlocks
  • Clean pouch connector, controlled fill valve and seal tester

06 · Failure criteria

Stop or redesign when evidence fails

  • Net water yield is impractical at the target climate.
  • Parasitic energy eliminates the useful production rate.
  • Condensate or treatment output fails water-quality requirements.
  • Wetted materials cannot be safely cleaned or verified.
  • UV or electrical interlocks permit unsafe exposure or operation.
  • Packaging allows leakage, recontamination or misleading shelf-life claims.
  • Cost per verified liter is not competitive for the intended mission.

07 · Immediate next experiment

Produce the climate-performance map

Run a controlled dehumidifier bench test at several temperature and relative-humidity points. Independently measure electrical energy, condensate mass, ambient state and every auxiliary load. The first decision is whether the measured liters-per-kWh curve justifies treatment and pouch-filling development.
