Abstract 

Here I continue my serial about free and carbon-neutral gas and oil. [1]. [2].

(a) CO2 = CO + O2 – 283 KJ, here CO2 is used in cycle, CO = 283,000 * 0.004 /3.6/28 = USD 11.2 /ton CO.

(b)  CO + H2O = CO2 + H2 – 3 KJ, negligible, here H2 -free, if CO2 (mol) = CO (mol)., or CO2 = 11.2 * 28 / 44 = USD 7.1 / ton CO2 here..

(c) CO2 (from the air) + 4H2 = CH4 + 2H2O + 254 KJ. CH4 = 1144 kwh/ton CO2 * 0.004 * 44 /16 = USD 12.4 /ton CH4, and 254,000 * 0..25 energy efficiency heat in electricity = USD 0.05 /kwh local tariff /3.6/16 =  USD 55/ton CH4, and a net profit is 55 – 12.6 = USD 42.4/ton CH4.

 

Such technology extracts from the air one mol CO2 only for a mol of CH4 produced free with a net profit USD 42.6/ton CH4.

CV-2023

 CV-2023, David Judbarovski, systems engineering, principle inventor, Israel cooperation and consulting Being very productive principle inventor and investigator on a firm basis of my work in wide spectra engineering and economics, I am sure that energy and production have to be and are ready to be green & cheap & abundant & inexhaustible, while all materials and parts and tools for that purpose can be recyclable. Short professional CV I was born in former USSR in 1939. 1962 –I was graduated as Dipl.-Eng. in Mechanics and Technology with emphasis on control and automation in chemical industry and mathematic simulation. 1962 –I was starting my professional career in systems engineering, at first with emphasis on applied mathematics methods. Through my life I had a duty experience in course in: (1) air traffic control, (2) microbiological industry, (3) pulp and paper industry, (4) technology of microelectronics, (5) capital construction, (6) typical design, (7)...

Comics for quick reading and search information from data-base

  Author: David Judbarovski, systems engineering, principle inventor, retired; ; "Comics" for quick reading and search information from data-bases . davidjud.blogspot.com, judbarovski.blogspot.com   1939dmj@gmail.com , judbarovski@gmail.com     Abstract Comic strip, or abstract of abstract, in short "comics" of multi-page or mega-page book, scientific work, etc. of printed or internet form, can allow quick reading and search them. Mostly, it is enough to read "magic first five lines of them" to understand what can wait him from the rest ones, and he can scroll pages only. The comics allows to address the reader to key information only to read it more attentively.

Russian black business

  Кремль продолжает продвижение кампании по отбеливанию имиджа России за рубежом. И заявления "хороших" россиян, которых Запад вытащил из российских тюрем в рамках обмена, – часть этой спецоперации. "Россия и Путин — это не одно и то же", "санкции должны быть направлены на преступников и режим Путина, а не на граждан РФ", да и вообще Украине "надо садиться за стол переговоров" с Россией.   Нет, это не очередное изложение заявки сумасшедших кремлевских вождей или их пропаганды.   Это первые   заявления   освобожденных из российских тюрем российских "оппозиционеров", сделанные 2 и 3 августа в Германии.  Они сильно возмутили украинское и европейское общество
