Renewables-2017

David Judbarovski, systems engineering, principle inventor. Judbarovski.blogspot.com, judbarovski@gmail.com. Notes. (1) Solar and Wind energy can be cheapened down to $ 0.01/kWh and even much less. [1]. (2) Roadmap to cheap and green hydrocarbon fues. [1]. (3) Supercheap and clean hydrocarbons production down to $ 33/ton alkanes = $ 4.1 /bbl. [2]. Abstract. Ethylene OPEX cost can be $46/ton vs more than $1000/ton now. How it works: It is a two-steps chemical process. (1) CH2 + H2O = CO + 2H2. dH = 167, dS = 245. (2) 2CO + 4H2 = C2H4 + 2H2O - exothermic reacton. Here 4H2 is circular, and so being practically free. Q (CO) = (14 * 33 + 167 * 1.1)/28 = $ 23.O/ton CO. Q (C2H4) = 2*28*23/28 = $46/ton C2H4. In the another case, 2CH4 = C2H4 + 2H2, dH = 2 * 75 - 53 = 97 kJ, dS = 219 + 262 - 2 * 186 = 129 J. Q (2C2H4) = (2 * 16 * 150 + 97 * 1.1) / 28 = $175 / ton C2H4. 2H2 is a by-product. Refewrences.

David Judbarovski, systems engineering, principle inventor. Judbarovski.blogspot.com, judbarovski@gmail.com. Note. Solar and Wind energy can be cheapened down to USD 0.01/kWh and even less. [1] Abstract. (1) 2CH2 (alkane) + 2H2O = CH4 + CO2 + 2H2 , dH = 72 kJ, dS = 220 J/mol*K (2) CO2 + (3 – 1) H2 = CH2 + 2H2O. exothermic. OPEX cost of alkane is USD 64 /ton CH2, or USD 9.0 /bbl. (3) = (1). OPEX cost of CH4 = (2 * 14 * 64 + 72 * 1.1) /16 = $ 120/ton CH4 = $ 84/1000 m3.

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.
