Renewables-2017

Abstract. Water/Desiccant CaCl2 is considered below to prove its big superiority vs. any other renewable energy power plants. CaCl2 + 4H2O = CaCl2*4H2O - 251 kJ, followed by its reverse reaction (recycling) by exhaust heat. Its electricity product is 0.035 USAcent/kWh, if USD 250 /ton.. CaCl2 and 4000 hours of its work in a year. Its footprint is negligible vs. countries area. Disclosure for experts. CaCl2 + 4H2O = CaCl2 * 4H2O - 250 kJ. CaCl2 (M = 111, dH = 795 kJ /mol * K, 2.16 g/cm3). CaCl2 * 4H2O (M = 183, dH = 2010 kJ/mol * K, Cp = 251 kJ /mol*K, 1.83 g/cm3) . If CaCl2 being 50 mm layer, and H2O being 72 mm correspondingly, dT = 270 C, and T = 300 C. if desiccant unit being 1 m2 area. Layer of CaCl2 = 2.16 × 50 mm = 110 kg = 1000 mol. So H2O = 72 kg correspondingly, and 250 kJ × 1000 / (72,000 gram H20) = 3.5 kJ/g H2O consume, or 3.5 × 72,000 / 3,600 sec. = 71 kWh heat × 0.25 (efficiency) = 18 kWh electricity/ m2. If such cycle supposed to be 5 minures = 1 / 12 hr, it...

Bloomberg отмечает, что Украина поставила своей целью изготовить не менее 50 тысяч наземных роботизированных платформ до конца этого года. Президент Украины Владимир Зеленский подчеркнул, что беспилотные наземные комплексы стали неотъемлемой частью современной войны. «Уже невозможно представить оборону без дронов и то же касается беспилотных наземных транспортных средств. Логистика на передовой, эвакуация раненых, боевые задачи – использование беспилотных наземных транспортных средств сейчас расширяется самыми быстрыми темпами», – отметил он. В материале также упоминается операция на Кинбурнской косе, проведённая в июле. Тогда украинские военные доставили дистанционно управляемого боевого робота к побережью с помощью морского беспилотника, преодолевшего 11 километров. "Наземный робот Wolly 7.62 был оснащен пулеметом с боекомплектом, из которого он обстреливал позиции российских войск, заставив их отступить с части побережья, после чего робот самоуничтожился", - говорится...

Present Strait of Hormuz crisis reminded once again about bottlenecks of maritime transport and logistic, but here is urgent temporary panacea to substitute of crude oil import, now is blocked, by natural gas plus can carry other cargo. It is unmanned blimps (i.e. foldable with flexible wall airships), filled by natural gas. It can be a fleet of standardized blimps, used and manufactured distributelly in a huge quantety, 36 km/h, some thousand km range. They can be manufactured automatized by total cost being negligible vs. a cost such initiative. Another way can be to reform oil into gas for transportation would be much more expensive (about USD 450/1000 m3). (1) sustainable and cheap transport (2) mobility strategy, (3) militery mobility, (4) security and safety, (5) infrastructure and investmens, (6) research and innovations, (7) international relations.

От: Austin Duncan Date: пт, 31 июл. 2026 г., 18:02 Subject: ​David / Engineering & Innovation To: Hi David, I recently came across your background and was impressed by the breadth of your engineering experience and your lifelong commitment to innovation. Your work across systems engineering, applied mathematics, automation, and multidisciplinary research, combined with your extensive experience as an inventor, reflects a rare ability to solve complex technical challenges from first principles. I’m currently advising a few organizations that are expanding their technical leadership and innovation capabilities. They’re particularly interested in individuals who can bring deep engineering insight, cross-disciplinary thinking, and practical problem-solving to advanced technology and R&D initiatives. Your experience developing concepts across engineering systems, energy, manufacturing, automation, and applied research stood out as an especially interesting fit for the type of...

controlled water flow or showering on desiccants (solid or liquid) is creating a heat, can be high temperature one to feed turbine electric generator.

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...
