Renewables-2017

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...

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.
