[1] Abstract. (1) 2CH2 (alkane) + 2H2O = CH4 + CO2 + 2.3 H2 , dH = 72 kJ, dS = 220 J/mol*K (2) CO2 + (3 – 2.3/2)H2 = CH2 + 2H2O. exothermic. OPEX cost of alkane is USD 30 /ton CH2, or USD 4.0 /bbl. (3) = (1). OPEX cost of CH4 = (2 * 14 * 30 + 72 * 1.1) /16 = $ 48 /ton CH4 = $ 30 /1000 m3. In its turn CH4--->CH2 estimated analogously, it gaves CH2 = $2.0/bbl and $20 / 1000 m3 CH4. References.

Израильтяне выбирают пробки: развитие инфраструктуры не смогло пересадить страну на общественный транспорт 2 сентября 2026, 15:14 Экономика За последнее десятилетие транспортная карта Израиля существенно изменилась: открылись новые железнодорожные линии, запущены линии легкорельсового транспорта, а автобусные сети расширили свои маршруты. Однако ожидания государства столкнулись с прямо противоположной реальностью. Согласно свежим данным опроса Центрального статистического бюро за 2025 год, жители страны предпочитают ежедневно простаивать в заторах на личных автомобилях, а популярность общественного транспорта продолжает падать.

It is a device, can produce fresh water, abundant and inexhaustible, by 26 cents /m3-payback 1 year + 0.2 kW electricity + 0.15 kWh recycling. It is a small, compact and mobile device. Who is me: See cv-2023, davidjud.blogspot.com/2023/04, posted on April 27, 2023. What I want: To join a small group for possible patenting as a novel method/technology and introduce it by startups. How it works: It pulls natural air and transforms its humidity in liquid water by chain: fan-turbulator-desiccant-its recycling-condenser, when heat being its by-product used for recycling. David Judbarovski, systems engineering, principle inventor, judbarovski.blogspot.com, judbarovski@gmail.com. P.S. Shortly. If a work season from March to October is about 5900 hr., absolute humidity averaged is 10 g/m3 at 15 nm3/s the fan, so it is 3200 m3 H2O production in a year. If a cycle is one hour, CaCl2 desiccant of 1 year lifetime, 250 $/ton = 0.26 cent / m3 H2O. The fan consumes 0.2 kW electric...

Три израильские компании вошли в мировой топ-30 военной промышленности 1 сентября 2026, 17:45 Экономика Все три крупнейшие израильские оборонные компании впервые одновременно вошли в первую тридцатку крупнейших производителей вооружений мира. В опубликованном Defense News рейтинге за 2026 год Elbit Systems занимает 21-е место, "Авиационная промышленность" (IAI) — 27-е, "Рафаэль"— 30-е. Рейтинг составлен на основе оборонных доходов компаний за 2025 год.

Desiccants novel applications. August 27, 2026. Innovators: Abstract. The device offered here is well known, but novelty is its tremendous applications, for example, it being a panacea in wartime and other crisised situations, for large scaled irrigation of desert and arid lands and so on by extracted natural air humidity. Such device is tremendously mobile and compact, its recycling gives the water-product and the heat - its by-product, used for that recycling. its water-produced can be competitive by cost, abundant and inexhaustible. Closed tank is equipped by: (1) container with exotermic CaCl2 desiccant, (2) input and output for natural humid air and its exhaust, (3) turbulant, and (4) blower for the said air. Claims. Claim 1. Device for the water supply in wartime and other crisised situations comprise closed tank is equipped by: (1) container with exotermic CaCl2 desiccant, (2) input and output for natural humid air and its exhaust, (3) turbulant, and (4) blower for the ai...
