That was really a fresh & new look now upgraded into a system, can produce by 0.25 US cent/kWh (because a lion share of the cost is gearless permanent magnet electric generator of USD 80.0/kW) and deliver that electricity reliably and safely to any point of the world in practically unlimited quantity by final cost less than 1.0 USA cents per kWh for any consumption schedule. The key ...

Thermal heterodyne for transformation of heat in electricity Author: David Judbarovski, systems engineering, Israel Linkedin.com   (165}-[3944]-01/02/2019 A mix of two thermal EM waves of the same intensity, but with a small temperature difference between them can be considered as well known technique of heterodyne to transform one frequency in another one being more suitable for application by engineering points of view.   If the said mix being received by an antenna transformer of electromagnetic waves in electricity, it is a breakthrough possibility to reach a highest energy effective transformation of heat energy in electric one by conventional cheap and light device with a help of rectifiers of much lower frequency. instead of a necessity to use of Terahertz   rectifiers.      

Water thermolysis and its products separation at weightlessness Author: David Judbarovski, judbarovski@gmail.com Linkedin.com, https://judbarovski.blogspot.com , https://judbarovski.livejournal.com A way to separate gases from liquids can be centrifugal force - the best method at weightlessness, especially in a case of water thermolysis. Earlier two different methods and devices for them were invented by me and were estimated as breakthrough cheap ones for water splitting in general, and for the water thermolysis.in particular. In the both cases the vessel can be ordinary plastic even at normal temperature, because the water environment is condensing the water vapor and cooling the hot products of the thermolysis. The earliest of them was a heating the water by several rays generated by a set of magnetrons and directed in small spot inside the water. The second way was specially designed walls at temperature about 3000 C inside a relatively small vessel. Centrif...

Extremely quick & cheap transportation Author: David Judbarovski, judbarovski@gmail.com Linkedin.com It is not a ground effect vehicle, but much better. One of key elements of my ship is to add the thin water steam cocoon created by electric heating a hull of the ship. It flows slightly lower than sea level, and the ship’s nose is tilted and forcing the upstream water to be thrown upward in the air, forming a surface wave along both sides of the ship route. It is new kind of sea ship, breaking all stereotypes. If ship is L * B * H = 100 m * 10 m * 6 m = 6000 m3 = 6,000 ton displacement, the outer surface S = 2 * (6 +10)   * 100 = 3200 m2, steam cocoon is created by power of Wsc = 5000 W/(m2 * K) * 3200 m2 * 10 K = 160,000 kW, speed of v = 900 km/h = 250 m/s, t = (6 m/ tan 15 = 22.4 m) / 250 = 0.09 sec, and Wp = 9.81 * (6 m/2) * (22.4 * 10 * 6) m3/0.09 = 441,000 kW / 0.85 = 520,000 kW, here 0.85 is a mover efficiency, and totally W = 520,000 + 160,000 = 680,0...
