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.
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
02 · Power module
Solar-battery planning build
03 · Energy flow
Every watt is accounted for
- Solar input Measure irradiance and electrical energy entering storage.
- Stored energy Track battery state and conversion losses.
- Condensation load Measure compressor, fan and defrost consumption.
- Treatment load Measure pumps, sensors and disinfection energy.
- Net result Report liters collected and treated per measured kWh.

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.
