Super high speed ship


Super high speed ship of big payload, May 2019

Abstract
A super high speed ship of big payload of my design provides extremely small transportation expenditures.  Being paired with the inland transportation in vacuum tubes, it would give tremendous influence on world markets and geopolitics.
There is a thin air cocoon around the hull of the ship under its waterline, and the ship’s nose is tilted back and forcing out the front water upward above sea level.
Such ship being 5000 ton payload considered below (e. g. 6 m * 10 m and 120 m length ~= 6500 m3 displacement) of 900 km/h speed = 250 m/s allows incredible low transportation expenditure about 0.022 kWh/ton-km

My ship’s design is based on two key ideas.
(1) A force of 900 km/h = 250 m/s being so big on front water being an incompressible matter, that the ship’s nose being a form of a wedge tilted back to above and to its sides, the nose is throwing/pumping/forcing the front water upward above sea level in the air, and it is forming two waves along both sides of the ship’s route.
The frontal drag power is W = (6000 m3 / (250 m/s / 100 m) * 6 m = 90,000 kW

(2) The air cocoon is created along the underwater surface of the ship. Its area is approximately 1500 m2 under a waterline. The cocoon is collapsing the water friction force. The frontal water flow pressure is 1000 * (250 m/s ^2)/2 = 312 atm., so the cocoon must be protected ahead by firm barrier. The cocoon is created by pressed air current through perforated shield sectioned by air pressure can be controlled to be slightly bigger than ambient water pressure corresponded its deepness, so the cocoon thickness can be quite small and a power needed to support the cocoon can be relatively negligible too and can be adjusted by membrane control of air pressure.

So the total power is about 100,000 kW, or 0.022 kWh/ton-km = 100,000 kW * (1 km / 900 km/h) / 5000 ton.

For example, a small ship offered here can substitute 150,000 ton supertanker by an order of magnitude cheaper CAPEX, and much cheaper OPEX.
Really, 6500 ton * 900 km/h / 40 km/h =150,000 ton displacement,

It can be effective used for export: fresh agriculture products, oil, natural gas without its liquefying, other heavy and mass cargo for a long distance, and as a military quick response.

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

Equipment for Short Take-off and Landing (E-STOL)

Equipment for Short Take-off and Landing (E-STOL) Author: David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com , Linkedin Abstract My E-STOL comprises a aerodynamic resistance of quite small area (SAR), being rigid and turnable, and a water jet device (WJD), comprising high pressure water jets in corners of quadrangular frame. The SAR can be very quickly erected or downed to turn it into additional wing-kite for short gliding in the sky. The WJD provides stabilization below stall speed and serves as start support, while landing or take-off. It is very attractive for Navy aviation, because allows high cruise speed, extremely short runway, and better reliability vs. helicopter, and we can repeat approach, if taking a portion of ambient sea water, in flight by simple pails.     The water is thrust out through the jets by gases at high pressure after ignition of “liquid vigorous combustible” (LVC), e.g. stoichiometric composition of amm

Breakthrough new fuel is better than oil

Breakthrough new fuel is better than oil David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Abstract Lithium hydride being reformed by water vapor in hydrogen then by fuel cell can create 5.25 kWh electricity/ kg. LiH, vs. 3.75 kWh per kg gasoline, while that LiH needs for its recycling 10.3 kWh renewable electricity , so system energy efficiency is 50% without any harmful exhaust. For the oil, analogous technology or by burning the both are followed by the oil recycling, they are 25% energy efficient with a lot of harmful exhaust.. Really For Lithium hydride, it was evaluated by me in the article : “Breakthrough kind of electric vehicle” in https://judbarovski.blogspot.com /2022/11 , posted at Nov. 05, 2022 For the oil, it is recycled from atmospheric CO2 and hydrogen produced by the water splitting.
