nx_water_awg.nx -- WATER SYSTEMS / ATMOSPHERIC WATER HARVESTING. Models the whole "get water from the air" landscape, not one dehumidifier, and recommends the best harvester for a climate (temperature + relative humidity): CONDENSATION -- refrigeration / dehumidifier (Watergen-class): cool air below its dew point. Needs humid air (RH >~40%), grid energy (~300 Wh/L). Psychrometric yield modeled. SORBENT -- desiccant / MOF (Berkeley MOF-303, SOURCE hydropanels): adsorb at low RH, release with solar heat. Works into the desert (RH >~15%), low grid energy. PASSIVE_CAP -- passive capillary-condensation material (UPenn 2025 amphiphilic nanoporous polymer, sciencedaily 250521): condenses in nanopores with NO energy input, at lower humidity than conventional cooling. FOG -- mesh fog harvesting (needs near-saturation / fog). RADIATIVE -- passive night-sky radiative cooling condenser. INTEGER-EXACT. Temp in C; RH in %; saturation vapor density g/m^3 x10; yield in mL; energy in Wh/L. Psychrometric condensation yield from a saturation-vapor-density table. THE exceed: given a climate it PICKS the right harvesting technology (desert -> sorbent; moderate -> passive capillary; humid -> condensation) and models the psychrometric yield + specific energy -- a real research-to-design step, sovereign, no hardware yet (honest). grounded: psychrometric_saturation_vapor_density + atmospheric_water_generator + upenn_amphiphilic_nanoporous_passive_harvesting_2025 + berkeley_mof_303_sorbent_awh genealogy_id: atmospheric_water_harvesting + nishi_water_systems
