Water JET Propulsion, the future way of traveling [concept] (C)

How will we travel in the future? The water jet propulsion! (C)

Especially in our time, we have to ask ourselves more and more often the question of how we can keep our standards efficient and environment-friendly in the future. The way we trade, transport and travel has to change. But airplanes, cars and conventional shipping are polluters. But one solution could be obvious: Water Jet Propulsion!

Not for nothing is our planet also called the “blue planet”. Only a small part of the area consists of landmass. Thus, the sea has always been and will always be a certain limit for man. Whether the North Atlantic, the Pacific or the Indian Ocean, these territories cover millions of square miles. The distances are big and the weather changeable. The open oceans are definitely not a nice place to stay.

With shipping mankind tries to become mother nature. The conditions at sea are tough, and it would not be the first time that the ultimate peace of mind can be found at sea. But now we are in the 21st century and modern shipping has existed for over a hundred years. With the invention of the expansion steam engine, the paddle wheel and finally the ship’s propeller, traveling by ship became a challange of everyday life. Ship travel was no longer an adventure. The speeds got higher and New York was only a few days away. For almost thousand years traveling across the Atlantic was only possible by boat. That’s how glorious names like Hapag Loyd and Cunard came into being.

But humanity is getting bigger and bigger and gets more and more a higher standard of living. People want to trade, people want to travel. The planes got bigger and faster. It only takes a few hours from London to New York. But this extreme emergence of long-distance transport strains the conditions of the possible. The capacities are always limited, fossil fuels are becoming scarcer and, above all, the environment is burdened by the extreme emissions of CO2 and particulate matter from marine diesel engines. But what choice do we have? Lowering the standard of living of industrialized countries will help the environment, but not the further development of humanity. We would have to face many ethical and economic questions. For example the question of how to explain to expectant industrialized countries, which do not yet have such a high standard of living, that they should not live as we others did before, could raise disagreement.

A mixture of both is the answer. We do not lower our standard, but improve it and adapt it to the circumstances!

Most trade is based on shipping. Ships usually have fuel-guzzling diesel engines. Fuel-guzzling diesel engines are not really good. So you should start at the root, face the rough problem and find a solution. In this case one could think of new design forms and more efficient drive modes of ships! This Design could be the answer:

The Atlantic Jet is a concept that combines the speed of an aircraft with the capacity of a cargo ship. Built to cope with the conditions of the high seas, this ship would have an average cruising speed of 70-75 knots, crossing the Atlantic from Southampton to New York within 48 hours. This would allow you to carry more freight and passengers in one direction than with 20 flights combined. But thanks to a streamline shape and an efficient engine, this ship would use less fuel than these 20 flights together! In the best case, one would develop a hydrogen engine for this size and have no CO2 emissions at all.

But to get that speed you have to clarify a few questions:

The shape of the ship and the construction. The ship would be built according to the Streamline principle. This means that there is a sharp point at the bow, the largest diameter is at the end of the first third of the length and the rest is narrow at the stern again. Sounds complicated? But it´s definitly not. Airplanes are built that way too. This means that air, in this case water, has an unobstructed flow around the ship, resulting in less resistance. As a result, the speed is higher and the fuel consumption decreases.

To reach 70 knots we need a new form of drive. A strong 10,000 hp diesel engine is not enough. Even a single propeller will not be enough. It is precisely for this reason that we have developed a new principle of locomotion. A water jet engine. We have adapted the principle of a real jet engine to the conditions of the water. With a real jet engine, air is sucked in, compressed and kerosene added and then ignited. The pressure that is generated in turn drives turbines that trigger the whole thing again from the front.

Of course you will not be able to ignite kerosene in the water. You can not really compress water, who had chemistry knows why. But is that really true? You cannot compress water? Right and wrong! You can not literally compress it, but you can collect it in a certain space and if there is too much water, then the water wants to escape somewhere. We use this simple principle for our own. We suck the water in, the space gets less and less, so it wants to back out all the more [=thrust]. Add hot air and / or steam to increase the pressure even more [= more thrust]. Now we could reach the speed we want.

The advantage is that you drive the turbine with a normal machine and thereby achieve a higher energy benefit. We almost double the energy that is generated and thereby get the speed. Due to the speed we need less days at sea: CO2 emissions remain theoretically the same, but we get more energy out of the fuel and thus achieve higher speeds [less days on sea] – seen over a longer period of time, we have lower CO2 emissions!



For the passenger! As important as the drive, is also the accommodation of the passengers. There are seven decks available for public use. Outside areas will not really exist due to the high speed and the resulting wind. However, there will be wind-protected boardwalks and promenades, as well as a pool deck, which is built against the direction of travel and fitted out with sidewalls [which also serve the aerodynamics] which protect from the strong wind. Within the ship, there will be plenty of spacious and skylight-lit areas for fun and relaxation during the 40-48 hours trip. This includes a “mall” which is to be equipped with franchise companies and chains. The benefits of our globalized world are also not overlooked. In this case a McDonalds and/or a Western Union store would also be possible at sea.

Passengers would not spend the night in cabins, but in spacious seating. These seats are separated from each other and offer privacy. On 1 – 2 square meters you would find a seat, which can be converted into a bed, a television – information tablet, as well as a small storage space. Toilets and showers are outside of these cabins. Do not worry, there will not be a shower like in the military. One would then register, to shower later in a one-man shower cubicle.

This efficient composition of space and privacy allows for a comfortable and fast journey. After all, you’re only a little bit more than a day and a night on the road.


But also the financing is important. How would such a journey be financed? What advantages does the customer have, how much profit can the company derive from it? This is calculation to give a look overview:





“And why this concept?” The advantages:
It offers a more environmentally friendly alternative to aircrafts and diesel freighters. Because less fuel is needed for the same amount of energy.

Cheaper than a plane ticket and more comfortable than a flight. You can even take your car with you. The route is the goal.

The crossing lasts between 24 – 48h [depending on the weather], a direct flight takes only 6 – 8 h. But the journey is more comfortable, no waiting at the baggage check, no waiting at the gate, no tight seats … and you do not have a jet-leg.
