Water and electricity from air humidity-draft

Water and electricity from air humidity - draft Abstract. Background. Claims The Three Operational Phases • Charging (Energy Input): Heat from a source—like a solar thermal array or industrial waste heat—is applied to a wet desiccant. This drives off the moisture, leaving behind a dry, high-concentration desiccant material. [1, 2, 3, 4, 5] • Storage (Energy Retention): The dried desiccant and the separated water are stored in separate tanks. Because the energy is stored in a chemical potential state rather than as sensible heat, it does not dissipate over time and requires no thermal insulation. [1, 2, 3, 4, 5] • Discharging (Energy Output): When heat is required, liquid water or water vapor from humid air is reintroduced to the dry desiccant. This "watering" process creates an exothermic reaction (heat of sorption), generating heat that can be used for space heating or domestic hot water. [1, 2, 3, 4, 5] Common Desiccant Materials Systems utilize either liquid or solid desiccant materials depending on the application design: [1, 2, 3, 4, 5] Desiccant Type Common Materials Key Advantages Liquid Solutions Calcium Chloride (CaCl₂), Lithium Chloride (LiCl) Easy to pump, scalable with single or stratified tanks, can double as a liquid dehumidifier. Solid Matrices Silica gel, Zeolites, Composite salt-matrices High structural stability, zero risk of corrosion, simple gravity-fed or fixed-bed designs.
