Breakthrough kind of electric vehicle

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.

Progressive city-car realization and powering-Updated,#1

Progressive city-car realization and powering-Updated, #1 Author: David Judbarovski, principle inventor, retired engineer, Israel judbarovski@gmail.com   Short CV: https://www.linkedin.com/in/david-judbarovski-1390944a/ Archive since 2017 yr: http://judbarovski.blogspot.be Archive since 2006 yr.: http://judbarovski.livejournal.com [3791]-3/11/2017,   My three levels’ conception of progressive transportation was disclosed in http://www.judbarovski.blogspot.co.il/2017/05/progressive-transportation-manifesto.html  (Progressive transportation manifesto, May 02. 2017). Its first level is a city-car.   Special designed city-car is a car moved electrically and equipped by very small battery as a city-grid element, and it isn’t big news now. Such cars are to be much cheaper and simpler than conventional cars and save a lot of energy. But I can suppose strictly to reject all sorts of powering them from underground, because it is energy ineffective and creates additional

Equipment for Short Take-off and Landing (E-STOL)

Equipment for Short Take-off and Landing (E-STOL) Author: David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com , Linkedin Abstract My E-STOL comprises a aerodynamic resistance of quite small area (SAR), being rigid and turnable, and a water jet device (WJD), comprising high pressure water jets in corners of quadrangular frame. The SAR can be very quickly erected or downed to turn it into additional wing-kite for short gliding in the sky. The WJD provides stabilization below stall speed and serves as start support, while landing or take-off. It is very attractive for Navy aviation, because allows high cruise speed, extremely short runway, and better reliability vs. helicopter, and we can repeat approach, if taking a portion of ambient sea water, in flight by simple pails.     The water is thrust out through the jets by gases at high pressure after ignition of “liquid vigorous combustible” (LVC), e.g. stoichiometric composition of amm

Breakthrough new fuel is better than oil

Breakthrough new fuel is better than oil David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Abstract Lithium hydride being reformed by water vapor in hydrogen then by fuel cell can create 5.25 kWh electricity/ kg. LiH, vs. 3.75 kWh per kg gasoline, while that LiH needs for its recycling 10.3 kWh renewable electricity , so system energy efficiency is 50% without any harmful exhaust. For the oil, analogous technology or by burning the both are followed by the oil recycling, they are 25% energy efficient with a lot of harmful exhaust.. Really For Lithium hydride, it was evaluated by me in the article : “Breakthrough kind of electric vehicle” in https://judbarovski.blogspot.com /2022/11 , posted at Nov. 05, 2022 For the oil, it is recycled from atmospheric CO2 and hydrogen produced by the water splitting.
