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.
