| 1 | Wilfried Ellmer prototype submarine | Built 1996 in Thauer ( Tirol Austria near Innsbruck ) | Launch operation at lake Attersee | The man on top is wilfried ellmer, builder and owner of the hull | Watch the acrylic hatch and side window of 5cm thickness and 50cm diameter | The hull is floating without ballast roughly on the middle line | this means half of the displacement is used up for the hull weight the other half is usable for machinery, ballast tanks, and interior outfit | The thickness of the hull is 18 cm | The weight of the hull about 10 metric tons | The displacement is about 20 cubic meters | The Prototype was dived and tested successfully in the Lake | When Wilfried Ellmer moved to Southamerica he parked the submarine at the bottom of the lake as ongoing experiment to check on how the hull would develop over the following decades staying in the water all the time and with absolutly no maintainence shedule performed | Two decades later this question is answered . A hull of this nature (if built well) is immune to the corrosion and deterioration of any kind and in perfect shape two decades later | read more about the prototype hull and see more pictures | | conclusions : the concept of building a submarine hull that can stay in the water for a lifetime is feasible | The depth rating of such a hull is at least 500m including ample safety factors (1:3) which makes it superior to a steel submarine hull | The lessions learned in the prototype project lead to further concepts | advanced cement composite technology | Termite-Tech™ | New-Atlantis™ | ocean colonization technology | Floating-Rock™ | ocean sphere

| 2 | The black hull is a much bigger submarine built in Cartagena Colombia | Displacement is 200 tons | It is the room and space equivalent of a 68 square meter apartment | The hull was built for a California Customer ( Ian Roxborough ) | The idea was to create a floating habitat similar to what Piccard and Grumman did in the PX 15 project (Benjamin Franklin) | This submarine mobile habitat did a current dive in the Gulf stream back in the summer of 1969 of 1,444 nautical miles from Florida to England crossing the Atlantic Ocean without the use of an Engine in 30 Days. Benjamin Franklin Drift Dive . Our Hull is about twice the size of the PX 15. So it allows for much more comfort, store space and therefore longer voyages and bigger crews. Other than the Ben Frankling which was towed into main current of the Gulf Stream, our boat can move under its own engine and is therefore independent of a mothership. The general idea is to create submarine yacht that is independent of any infrastructure and capeable of doing global voyages. See a walktrouh of the finished raw hull here . The project is the exploration of the technology base for the NautilusToken™ a private submarine on worldwide voyage doing all kind of business in the ocean.

| 3 | Many people envision the interior of such a submarine habitat as a dark and unfriendly place. This is a perception error. see more about submarine Yacht interior design There is no reason why the interior of a submarine yacht needs to be darker or uglier than the interior of a yacht or a business jet. In fact a submarine yacht is an upgrade in interior design as the space is wider than the interior of an airplane and can carry a far heavier outfit including things like a jaccuzzi.

| 4 | See a vision of how living and traveling in a submarine yacht is - compared to normal yachting. submarine yachting a practical approach - live aboard - storm The energy requirement for propulsion and climatization is ten times lower than for a normal yacht. There is a good reason why all animals that live in the ocean are designed to be "submarines" nothing is swimming on the watersurface. Mother natures designs are much more efficient than human ship designs.

| 5 | The prototype hull in Thauer is out of the shed and ready for transport. Wilfried Ellmer the crane operator and neighbours checking the event.See the 50cm diameter front viewport. A submarine of this size ( 20 tons ) is more or less the limit for operation as mini submarine looking out of a viewport. The bigger the submarine gets the less feasible it becomes to bring the viewport close enough to an underwater object to see anything. Therfore bigger submarines use camara sistems and screen walls to get a picture of the outside world. This picture can also be enhanced by augmented reality. It is a bit like in the Enterprise scotty put it on screen and everybody can see it. There are not people running through the ship finding a viewport that allows a good angle on what is outside...

| 6 | The original prototype has about the size of a van, its weight fully ballasted is 20 tons. In yacht building the rule of a thumb for the engine need is about 3 horsepower per ton of shipweight that would leave you with a 60 horsepower engine meaning a car sized motor. On the other hand i was intrigued by the biological design of whales, they do incredible long oceanic voyages on very low energy. A 20 ton whale does not require more than 200 Watt to move around at a nice speed of 5 knots. So i made this the baseline for the engine installation. This kind of electric motor would rather be normal on a dinghi than a 20 ton yacht. Nevertehless i found out that it was capeable to push the boat against any storm ( i encountered a few ) bring the nose into the wind and steer a exact course in any condition. So mother nature's design is a good one.

| 7 | I fitted the boat later with a small handheld diesel generator to recharge the batteries which gave me a unlimited range. So while it is problematic in live aboard yachting to run the big engine for reloading the battery on a submarine yacht it is very feasible to combine a yacht electric sistem with a small generator and insulate this generator behind a heavy wall making it unperceptible when running it on the anchorplace.

| 8 | Whales do incredibly long voyages with very little energy requirements. The annual voyage from the arctic regions to the tropics are a good model how you can run a submarine yacht. It comes up to to basicly the same energy use if you travel long distance or you simply stay in one place and run the basic energy needs of your habitat household. A small generator and a battery pack do the trick. It is just the same as running a family home.

| 9 | A letter from Jules Verne to Simon Lake shows where the original inspiration for Captain Nemo came from. Although the Nautilus had a base, it was on a global voyage doing stuff like recovering "the lost treasure of the incas" from sunken spanish galleons. ( Simon Lake ) . A submarine yacht gives a maximum of independence, complete immunity to weather and storms, a sea sickness free travel experience, interference freedom due to the independence from ports and infrastructure. It is also the best of all thinkable prepper solutions combining bunker style safety with a high degree of mobility.

| 10 | The quest for freedom on the ocean leads to the idea of seasteading. This is another idea brought up by Jules Verne, after his voyage on the Great Eastern. The key question here is: How do you create buildings that can float permanenty on the ocean without their bases rotting away in a few years. As we developed your technology further, we came up with an advanced cement based building technology, that allows something like a floating city the first time in history.
