Military value of extra-quick ship of my design Author: David Judbarovski, systems engineering, principle inventor, retired judbarovski@gmail.com   Abstract Being compared with typical destroyer (Type 055, Japan) = USD 60,000,000,00; 13,000 dwt; 112,000 kW; 56 km/h, and with Boeing 787-9 airliner = USD 30,000,000,00; 55 ton payload;   80,000 kW; 900 km/h, my ship is better than the said destroyer in 30 times by CAPEX and 9 times by OPEX, and can substitute 8 destroyers. Correspondingly, with the airliner, 200 times by CAPEX and 80 times by OPEX, substituting 100 them by one ship   Very shorty, Two key elements of my ship are (1) Slightly lower than sea level, the ship’s nose is tilted back and like a wedge it bends the upstream water upward in the air, and it substitutes the big water resistance by the air resistance being in three orders of magnitude less one   Such energy effect is inherent for very big velocity .. It is new kind of sea ship, breaking all stereot

Breakthrough quick ship. Economical aspects Author: David Judbarovsk, systems engineering, principle inventor, retired judbarovski@gmail.com   Abstract Extremely quick & cheap sea transport of my design can multiple save Capex vs. present ships. It can be effective used for export: fresh foods, other mass cargo for a long distance, and as a military quick response.  A power of my ship is proportional to its speed, while for conventional ships it is to the cube of speed. As idea it goes back to summer, 2018. Two key elements of my ship are [1]: (1) Slightly lower than sea level, the ship’s nose is tilted back and like a wedge it bends the upstream water upward in the air, and it substitutes the big water resistance by the air resistance being in three orders of magnitude less one   Such energy effect is inherent for very big velocity .. It is new kind of sea ship, breaking all stereotypes. (2) to add a thin pressed air cocoon created around a hull of the ship.

Advanced kind of cargo ships Author: David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Abstract The cargo ship can be fueled by ammonia, if a service crew being at safe distance on a separate vessel.   The said ammonia has to be free of carbon derivatives and sulfur ones,. If decomposed. it is feeding H2-air fuel cells to power the ship’s electric engines.   Such fleet is much more energy effective vs. conventional fleet, and doesn’t use any moving parts at high temperature, and its exhaust is clean, being the water steam and inert nitrogen. My especial attention was dedicated for following problems of ammonia fueling. (1) The ammonia must be without contaminants, poisoning the said fuel cells. For that purpose, the ammonia can be produced “from water and air”. I can underline that it can be extremely cheap ammonia, isn’t implying cryogenic air separation.in nitrogen with oxygen as by-product.[1]. Hydrogen is another component of a
