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 ...
Green and cheap H2, CO, and hydrocarbons. Corrected on August 04, 2025. Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com. Abstract Simplified technology promises USD 161/ton H2, USD 11.5 /ton CO, and hydrocarbons of USD 6 /bbl. They are OPEX, and in order of magnitude cheapеr than prices of fossil fuel and can use now existing infrastructure. (a) CO2 [1] + H2 = CO + H20 - 3 kJ negligible. Here everywhere CO2 is circular and free. A cost of H2O is negligible. If Q served for a cost, Q(CO) * 28 = Q(H) * 2, so Q(CO) = Q(H) / 14. (b) [2] CO + 1.5 H2O = CO2 + 1.5 H2 + 0.25 O2 + 146 kJ. 146 kJ = 146 * 4/ 3.6 [3], [4] = USD 161.0 /Mmol. 1.5 * 2 * Q(H) - 161 = Q(CO) * 28 = 2 Q(H). So Q(H) = USD 161 / ton H2. and CO = Q(H)/14 = USD 11.5 /ton CO. QED ! CO2 + 3 H2 = CH2 (hydrocarbons) + 2 H2O - 240 kJ. 240,000 * 0.3 (efficiency heat in electricity) * 0.03 (tariff) / 3.6 = USD 600 /Mmol So 14 * Q(CH2) = 5 * ...

It doesn't need a special start/land pods, but only permitted by ordinary air traffic safety regulation. Abstract. A key element of the possible invention is a VTOl and strategy can lift and land a satellite or/and materials relatively free if the VTOL design of my invention of 40 kW/ton, see Vertical take-off amd Landing Device - 20.07.2020, see judbarovski.blogspot.com/2020/07, posted on July 20, 2020. Satellite is served on low orbits, its PV direct solar illumination can be 10 hr.* 1.4 kW * 365 days a year = 5000 kWh/m2 of the PV receiver. Down to 10 km using ICE, expenses are negligible, then and lower than designed orbit it is CH2 + pressed oxigen for jet mover, and then accelerated. For example, if 100 ton satellite, to reach an orbit 300 km hight it consumes 2 hours and about 1.6 ton kerosene and 4.5 ton 300 atm. pressed oxigen by a tota...
