Water and electricity from air humidity - draft Abstract. Background. - Google AI: 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 s...

Full needs in water and energy supply by the natural air consumption only. Abstract. E (kWh) is electricity annual production, so (E * 3600 sec. /0.3 efficiency) / (40.66 kJ /18 g.) gram H2O /10^6 = (5.3 * 10^3 * E) m3 of the H2O annually, can be separated and simultaniously condenced air humidity, producing a hight temperature clean water vapor and energy with a help of small about 1.0 m2 gas centrifuges. Water and electricity in hotest deserts can be not a dream, but reality. Roadmap. (1) About 1.0 m diameter gas centrifuges allow to concentrate the said humidity in some steps up to its condensation into fresh water, (2) then it can be patented, (3) a heat of the condensation can be utilised in electricity, (4) then it simply and cheaply scalable as a distributed system, (5) then can be transfered technology. Numerical estimations of the said know-how. The Netherlands as example. E = 132 * 10^9 kWh electricity, annually + the water of 5.3 * 10^3 * 132 * 10^9 /10^6 = 700 * 10^6 ...

Israel. 2.4×10^9 m3 H2O annually = 80 m3/sec. = 80×10^6 gram/ (11 g/m3 air humidity) = 7.2×10^6 m3 air/sec. Centrifugal air separation in (3 steps x 6 min = 0.3 hours in a step = 25,000 in a year . So 7.2 × 10^6 m3 air ×3.600 sec/25,000 = 10^6 cenrifuges, or 7.2 m3 air for one step of separation. 2.4×10^9 m3 H20 × 10^6 g × (40.66 kJ/mol)/(18 g/mol)/3.600 sec. = 1.5 ×10^12 kWh × 0.3 = 500×10^9 kWh electricity as a by-product.

Abstract. Full Israelian needs in the water, and energy in a form of electricity consuming the natural air only and 0.001% land area as a footprint. July 20, 2026 Israel. 2.4 milliard m3 of the water annual consumption, or 80 m3 /sec, can be extracted from the air humidity, being about 15 g/m3. (1) About 1.0 m diameter convention gas centrifuges of quite common velocity about 50-100 rotation/sec. allows to concentrate the said humidity in some steps up to its condensation into fresh water, (2) then it can be patented, (3) a heat of the condensation can be utilised in electrisity, (4) then it simply and cheaply scalable as a distributed system, (5) then can be transfered technology. Numerical estimations of the said know-how. Israel. 2.4×10^9 m3 H2O annually = 80 m3/sec. = 80×10^6 gram/ (11 g/m3 air humidity) = 7.2×10^6 m3 air/sec. Centrifugal air separation in (3 steps x 6 min = 0.3 hours in a step = 25,000 in a year . So 7.2 × 10^6 m3 air ×3.600 sec/25,000 = 10^6 cenrifuges, o...

В Николаеве мужчину 18 суток содержали в помещении ТЦК после того, как во время мобилизации ему сломали ребра. Об этом сообщил уполномоченный Верховной Рады по правам человека Дмитрий Лубинец. По его словам, во время проверки документов выяснилось, что мужчина уже действующий военнослужащий. В то же время, он продолжал находиться в помещении ТЦК, а не был направлен в свою воинскую часть. "На наш вопрос, а как он может до сих пор быть в этом помещении, а не отбыл в распоряжение своей воинской части, мы получили ответ: у него были сломанные ребра во время проведения мобилизации — ждали, пока ребра срастутся", — рассказал Лубинец.

July 15, 2026 A roadmap to cheap and green hydrocarbon fuels, it is offered here. (1) Cheap renewable energy. To be competitive, artificial fuel needs for its synthesis from CO2 of the air and H2 by the water splitting, energy for it must be cheaper than USA cent/kWh or so. A cost of primary energy of Solar and Wind in the order of magnitude can be cheapened by reducing their frontal dimension down to about 1.0 m2 unit, so such units are thinner proportionally and is negligible vs. a cost of electric generators being a lion's share per kilowatt, and cheaper than 0.5 UScent/kWh. For example, see 2021 Annual Meeting. (397e) Cheap Energy is Key to Competitive Artificial Fuels. www.aiche.org/conferences-events. (2) Breakthrough cheap and green and inexhaustible Hydrogen production by low temperature water thermolysis at about 300 C vs. 2500 C conventional and sufficiently lower than auto-ignition at 450-500 C, instead of very expensive electrochemistry. I can offer 4 different technolo...

July 13, 2026 Now we can see three urgent problems of different levels of urgency. Just below you can see quite understandable ways to decide them followed each by short dislosure for experts. (1) Strait Hormuz crisis. Looked unsolvable one, but the oil and other export/import in the huge quantities but cheaper and much more directly would be by the air. A fleet of 400,000 blimps, manufactured and used distributely would be a panacea.. Such system can be started practically immeiately, payback is one year and USD 6 milliard totally. More detailed and estimated see in judbarovski.blogspot.com/2026/07, posted on July 06, 2026, EC DG-MOVE.E1. Urgenly.

The water thermolysis by NH3 circular. June 12, 2026 (1) N2 + 3 H2 = 2 NH3 is circular, so practically free. dH = -92 kJ /mol, dS = - 200 J/mol * K. T 300 C. A cost of the hydrogen is a cost of a heat for the water thermolysis (reaction 2) minus a cost of sold by-product of electricity (exotermic reaction 1), so USD (286 * 0.25 + 92) * 1.1 / 0.5 -(92 * 10^6 / 3600) * 0.15 (efficiency) * 0.03 (tariff) / 0.5 = USD 130 /ton H2.

[1]. (1) Al2O3 + 3 H2O = 2 Al(OH)3, heating and pressure 10 - 100 bars. 2 Al(OH)3 + k * (H2O = H2 + 0.5 O2) + Al2O3 + 3 H2O. All reagents are circular here, so they are practically free. Total energy consume is energy for the water thermolysis only, and at k = 1, being a heat of 242 kJ/mol H2 at T = > (150 + k * 242) / (450 + k * 54) = 500 C. vs. 2500 C conventional. If k = 0.5, T => 300 C. H2 product can be 242 kJ * 10^6 * 0.004 /3600 sec./2 = USD 133 /ton H2. If treated H2O is liquid and k = 0.5, T => 280 C. (2) Catalyst: CO2 + H2 = HCOOH - formic acid. Joint target reaction: HCOOH + 0.4 * (H2O = H2 + 0.5 O2) + CO2 + H2. dH = 32 + 0.4 * 242 = 128 kJ. dS = 214 +...

Mrs. Paula Clara Rutter-Moschuetz (Competition, Customs). Date: July 06, 2026. Present Strait of Hormuz crisis reminded once again about bottlenecks of maritime transport and logistic, but it can be helped by unmaned blimps (foldable airships with flexible thin walls), as a panacea, carrying a tank for cargo. Each tank equipped by engine and four tiny and cheap sensors of altitude and some propellants for soft landing, especially if crash cases, wartime etc.. Such airships are filled by light gas, e.g. hydrogen or ammonia or methane For example, for import/export of 2.0 milliard ton cargo annually, 1.0 cent/10 ton-km. It can be a fleet of 400,000 standartized airships used and manufactured distributelly in a huge quantety, USD 15,OOO, 36 km/h, 250 kW. 70 ton cargo, 10% of its weight is a fuel for 5,000 km range.

(1) CO + H2O (gas) = CO2 + H2, dH = - 41 kJ/mol. dS = - 86 J/mol *K, and T (41 + k*242) / (86 + k*54), and at k = 0.25, T>750C. So H2 (OPEX) = (41 + 0.25 * 242) * 1.1 / 0.5 - (41 * 10^6 /3600) * 0.15 * 0.03 = USD 120 /ton H2. if treated H2O being liquid and k = 0.25, dG = (- 3 + k * 286) * 1000 - (86 + k * 160) 270 C.
