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...

New kind of land traffic instead of rail one Author: David Judbarovski, Linkedin.com, judbarovski@gmail.com It is mainly a passenger traffic being provided by small high-speed pilotless air cushion vehicles (being a small capsule of one-two seats, can be jointed if being needed in something of train as at the station as on the road) traveling on a net of intercity roads, is cheaper and simpler built than ordinary dirt roads. You don’t wait at the station, but starting at the stations immediately. It is much safer and much more convenient than trains or cars. Its ticket price is practically negligible per one travel, especially if the said vehicles are electrical ones fed on the road, when traveling. Its road junctions can allow uninterrupted traffic analogously as it was described by me earlier (see https://judbarovski.blogspot.com/2018/10/ , in an article “Method to prevent traffic-jams on province roads”, October 20, 2018).  If being on-line optimized totally, the sy...

It had been submitted for South Korea conference   in 2013 Abundant & inexhaustible source being hydrocarbons from air, water and sunshine, and used to produce eco-friendly & extremely cheap & high-quality meat products Author David Judbarovski, pensioner, retired engineer, person for contact; postal address: str. Giborei Sinai 30/23, Akko, 24307, Israel ; email: judbarovski@gmail.com ; telephone number: 972-4-9811080 Executive Summery Present scientists and process engineers are concerned by a problem of eco-friendly & not expensive and satisfactory alternative to fossil hydrocarbons being now as a blood for our life and economics. Huge mass of agriculture products is devoured as a biomass for the alternative fuels production, and this entail serious rise of food prices, foods’ deficit in the world, and soil depletion.   Here I intend to look at the problem from reverse side, and to prove that present science and technologies are ready, ...
