Super economical antenna based engine Author: David Judbarovski, systems engineering, principle inventor, retired judbarovski@gmail.com   Abstract Super economical engine is fed by array of alternated antennas coupled with radiators, heated by heat carrier or by any combustible. The said radiator emits a band of EM waves of about 100 THz interfered each with the others forming envelope of much lower frequencies, e.g. 10 THz, can be detected by the said antenna into electricity with high energy efficiency, can reach near 100% after recuperation of exhaust heat.   If using Plank’s Law on-line calculator for blackbody, the Radiant emmitance   is W = 50.8 kW/m2, and if Band Radiance chosen at 10 THz around maximum, a t 700 Celsius the said efficiency is 92%. and 109 kW/m2, 76% at 900 C, but with much cheaper CAPEX   being more than an order of magnitude cheaper than secondary battery    

Breakthrough hybrid of heavy ship with aircraft Author: David Judbarovski, systems engineering, principle inventor, retired   It is a further perfecting of my conception of high speed heavy ship, now can fly and land on sea surface. It operates another than Boeing Pelican being ground effect fixed-wing aircraft. My concept is much more a ship than an aircraft, so very economical transport and needs less area of wings. The Boing Pelican is quite bad conception, because in modern wars such heavy transport being hit in high altitude, it would be fatal consequences.   Key ideas of my concept of a sea transport, breaking all stereotypes, and its theoretical consideration were described in “Novel fast and heavy ship, Corrected on 5.10.2020”, https://judbarovski.blogspot.com/2020/10 , was posted on 8.10.2020.    

  Petrol cheapening Author: David Judbarovski, systems engineering, princiole inventor judbarovski@gmail.com Abstract NG extracted at production site, it is reformed by water steam in CO2 and H2, cheaply cleanable, and then transformed, using additional portion of CO2 in clean petrol being more cheap than market prices of crude oil and much cheaper than refined one, The total system of production and usage produces less greenhouses and twice more energy effective, being reformed back in CO2 frozen to be divided, and H2 used for fuel cells.     (1) CH4 (NG-natural gas) + 2 H2O (water steam) = CO2 + 4 H2 + gaseous pollutants (a) it is endothermic reaction consuming 254 kJ / mole can be produced by additional   254 kJ / 64/ 16 = 0.25 mole CH4, but can be substituted by clean and cheap renewable energy   (b) CO2 and 4 H2 are cleaned from the pollutants cheaply by some water aerated and mineralized (2) 4/3 CO2 + 4 H2 = 4/3 (CH2) (petrol) + 8/3 H2...
