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 ...
Fuels, simply and cheaply. Author: David Judbarovski, systems engineering, principle inventor, retired. See my professional CV shortly in Linkedin.com. judbarovski.blogspot.com, judbarovski@gmail.com . Preamble My variant is based on extremally cheap solar and/or wind energy as a result of many years of my research and development. The said breakthrough cheap fuels can be produced domestically, distributed, and cheaply, and it allows to integrate huge amount of renewable energy in national grids, being now a sore and unsolvable problem. Roadmap manifesto from present energy fiasco via realistic half-greens to clean energy. And so on, and so on. Really. For classical Fischer-Tropsch process: (1) C + H2O = CO + H2 - 173 KJ, (2) 2H2 + CO = CH2 + H2O + 250 KJ (3) surplus CO -sold, by 50 * 28 = USD 1400, CH2 = 120 * 12 = USD 1440 + 173 * 4/ 3.6 = USD 200, And 250,000 * 0.3 (efficiency heat in electricity) * 0.033 /3.6 = USD 700.

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...
