Modern energy initiative for the West David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com, Linkedin 18.11.2022 European Union has been unprepared to Russian manipulations with oil and gas cuts of delivery and their prices risen, and is faced to be “frozen” in coming winter and collapse in a nearest future. I can suppose following step-by-step emerging initiatives can help. (1) Short-term (tactical) one for implementation as soon as possible Specially invented wind power generators (see disclosure in Note 1 bellow), being very simple and cheap in manufacturing can be quickly and simple installed distributed, promising electricity cheaper 1.0 eurocent per kWh, and serves to substitute natural gas for Thermal Power Stations and for heating. (2) Middle-term initiatives for 2023/2024. Such extremely cheap electricity being sold by much bigger prices can create budgets in growing rate (breeding investment) for the next wind power generators and in...

Hazard free stored and very effective fuel David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com, Linkedin Abstract (1) C2H5OH + 3 H2O = 2 CO2 + 6 H2 - 350 kJ, then cooled and pressed to separate gaseous hydrogen from solid carbon dioxide thrown out (2) 6 H2 + air by Fuel cell = 6 H2O + 1700 kJ * 0.75 (efficiency) = 1290 kJ, and totally 5.1 kWh per each liter of the fuel for electric vehicle powering each wheel vs. 3.4 kWh/liter if by gasoline for ICE. The C2H5OH can be recycled cheaply from the water and carbon dioxide extracted from the air chemically and very energy effective and consuming minimal footprint area and by renewable sources of energy, can be cheaper 1.0 cent US per kWh electricity and by different ways. Such fuel can be used by householders as autonomous powering and for reserve support of grid electricity supply. Being distributed energy supply, it is very important for war time.

Breakthrough kind of electric vehicle David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com, https://judbarovski.blogspot.com Abstract On board: 2 LiH + H2O = LiOH + Li + 1.5 H2 + 17 kJ at mild conditions H2 = H2/air FC = 40 kWh * 0.7(efficiency) = 28 kWh/kgH2 = 5.25 kWh/kg LiH fuel Materials are looped.so practically free ones. For comparison, 3.75 kWh/ kg gasoline, 30% energy efficiency Battery of conventional electric vehicle is in order of magnitude both heavier and more expensive. System’s efficiency with recycling is 5.25 / 10.3 = 50% Indeed, LiH-fuel recycling by renewable electricity: LiOH = (electrolysis) = Li + 0.5 H20 + 0.25 O2 = 342 kJ 2 Li + H2 = FC = 2 LiH + 182 kJ H2O = PEM FC or magnetron = H2 + 0.5 O2 – 286 kJ Totally 342 + 286 – 18 2 = 446 kJ /0.75 = 595 kJ = 10.3 kWh Q.E.D.

judbarovski Юнга Пассажиры Pip 15 сообщений Отправлено 09 мая 2004 - 11:30 ребята, я хоть и не яхтсмен, и не корабел, но как раз по этому возможно могу удивить по теме паруса будущего. полагаю, что таким будушим парусом будет SkySail немца Wrange, т.е. парус в виде воэдушного змея легче воздуха- скорость как у гоночного моторного катера, ведь на высоте и скорость ветра больше и сила как куб этой скорости. да и в спортивном управлении- кайф несравненный. правда по внутренней воде не развернёшь все возможности, но в открытом море хоть до америки с ветерком, и не только на небольшой яхте, но хоть на грузовике в тысячи тонн. Дурак-немец правда наполняет свой парус гелием, но можно ведь и природным газом, тоже ведь вдвое легче воздуха, зато дёшего и всем доступно, и не опаснее, чем пользование газовой плитой, и подстраховать это не дорого. у немца управление компьютеризированное и на этом он забуксовал пока, а спортсмен и без сложного софта легко управится... А насчёт наво...

Mutual beneficial energy deal to save EU and Ukraine David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Abstract It can help Ukraine and Europa to survive coming winter at fuels shortage now and forever. . Recently invented wind power generator (SVAWT), being simple, cheap, compact and reliable, it can be made of common and mass traded materials and parts, allows breakthrough cheap and distributed energy consuming totally minimal area, when Russia invasion and present extermination of infrastructures in Ukraine. Background The said SVAWT (special vertical axis wind turbine) was disclosed and evaluated as for politics and economist popularly, and as for professionals. Surplus power creates competitive fuels. (see “Promotion, new wind power, October 2022” , posted on October 12, 2022, in https://judbarovski.blogspot.com/2022/10 ). SVAWT is slightly heated at danger of freezing... As for Ukraine, it can be recommended in the said war time, to...

The slogan It’s possible to reach energy independency sooner and forever based on new look on wind power generation and common materials and parts mass produced and traded domestically, and maximally saving the nature and conventional fuels infrastructure and economics. What have to do for it? – Only to do it! As soon as possible. Synthetized fuels cheaper USD 70.0/bbloe, and how to reach it David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Promotion, popularly for politics and economists, followed by Disclosure for experts at the bottom To close 150 milliards m3 deficit of natural gas, it is enough about 50 milliard dollar budget. More than one year ago, Ministry of Energy (DoE) USA publicly admitting that more than 100 GW offshore Wind power capacity built in USA, is not an achievement, but disaster, and were forced to seek help outside their system for ideas (Request for Information (RFI) DE-FOA-0002389 asked by the DoE Office of Energy Eff...
