Practically free fuels - half-green variant

Practically free oil and gas - half-green variants. Author: David Judbarovski, systems engineering, principle inventor, retired, my CV see in Linkedin.com. Abstract. They allow to reach the oil (CH2) produced domestically and practically free, 0.5 mol CO2 extacted from the air, consuming 2.5 mol C per a mol CH2 and 2.0 mol CO being valuable by-product. It is allowed by extremely cheap solar and/or wind energy, earlier developed by me during many years. Such oil allows to integrate huge amount of solar and wind electricity to national grids, being now sore and unsolvable problem. C + H2O = CO + H2 ( Fischer-Tropsch process ) - 176 KJ. Here CO being valuable product, can be sold by USD 50 / ton or much more. H2 = ((12 * USD 120 / ton - 28 * 50) + 176 * 4 /3.6 ) / 2 = USD 100/ ton H2. Plus net profit from surplus CO being much more than 28 * 50 = USD 1400 if 2H2. C + CO2 (from the air) = 2 CO, (Boudouard reversible reaction, can be near 100 % energy effective at mild conditions ), so here 0.5 C + 0.5 CO2 = CO - 86 KJ, so here CO = ( 12 *120 / 2 + 1144 kwh * 0.004 * 44/ 2 ) / 28 + 86 * 4 / 3.6 / 28 = USD 29 / ton CO. CO + 2 H2 = CH2 + H2O + 226 KJ, can be converted in electricity and sold. So CH2 = ( 28 * 29 + 4 * 100 - ( 226,000 /3.6) * 0.3 efficiency heat in electricity * USD 0.03/kwh local tariffs) / 14 = USD 27 / ton CH2, so a barrel of oil is practically free. So each mol of CH2 and 2 mol CO is consuming 2.5 mol C, while it extacts O.5 mol CO2 from the air, cleaning it. and net profit more than 1400 / 14 = USD 100 per each ton of CH2 References. Roadmap manifesto from present energy fiasco via realistic half-greens to clean energy. And so on, and so on.

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

Progressive Transportation Manifesto

Progressive Transportation Manifesto. Author: David Judbarovski, systems engineering, retired engineer, Israel judbarovski@gmail.com , Linkedin: David Judbarovski  http://judbarovski.livejournal.com ,  http://judbarovski.blogspot.co.il   It can be three levels global transportation system. (1) Urban traffic is provided by specially designed cars only and being electric pilotless cars fed from electric grid, with a tiny battery needed for emergency occasions only and offered as a new market products being a city taxi analogously to the UBER taxi optimized by time of delivery, number of passengers and cargo load. It’s ecologically friendly transport can save a lot of money and time for its users. It will avoid a human factor and traffic accidents.    (2) Personal cars must be avoided from cities’ roads and collected on the personal cars stations outside the cities and serving for suburb’s or rural routes up to about 700 km range. I can offer a special cars design fo

Fresh look, Japan offshore

Central Research Institute of Electric Power Industry Japan, https://criepi.denken.or.jp/cgi-bin/en/inquiry/inquiry_entry.cgi   Dear Secretary, I can suppose you to be no big professional in engineering, so please forward my very interdisciplinary message to your institute professionals of Energy Innovation Center and/or to your Planning Group having intellectual Property Sectors, as its high importance merits for Japan energy security and economics and independence.   1.5.2019 Abstract During last three years the Japan government’s energy authorities declared and then rejected different Strategic Energy Plans (“SEP”), each more stupid than the previous ones, but the all of them need some trillions USA dollars of budget and being depended from foreigners. Being uniquely educated & experienced engineer (see short CV in attachment), I can confirm that Japan can be energy independent after three years of works by about one milliard USA dollars of total budget.
