- Explored using highly hygroscopic calcium chloride (CaCl₂) in a decorative laminar-flow “waterfall” to harvest atmospheric moisture, with internal LED lighting and fluorescent dye for visual effect.  
- Compared alternative salts (MgSO₄, Ca(NO₃)₂, CaSO₄) for hygroscopicity, solubility, corrosion risk, and flammability; concluded CaCl₂ remains optimal despite chloride-induced steel degradation.  
- Discussed passive mechanical regeneration concepts: a “drinking-bird” style shade/unshade cycle, wax-actuators (waxtuators) that melt/expand to open greenhouse-style vents, and a spring-loaded linkage that uses the mass gain of absorbed water to trigger desorption when heated.  
- Referenced historical atmospheric water generators (air wells) via RexResearch and Wikipedia pages to inform design of a solar-thermal dehumidifier that could double as low-energy air-conditioning.  
- Proposed reverse-osmosis as a potential method to regenerate the saturated CaCl₂ brine, enabling closed-loop operation of the moisture-harvesting system.
