Introduction: The Repulsine Project
Update 22/08/2015: Top diffusor now printable in two parts.
Update 20/08/2015: Top diffusor now in a version that can be joined with the top wave disk.
Update 19/08/2015: Top diffusor is finnished, at least for the model itself.
Will get an additional plate or similar for the printable version (if I figure out how to make these shape printable).
If you are a bit older and fascinated about old technologies you might have heard about Victor Schauberger's Repulsine.
Same of course if you are one the many UFO and conspiracy fans ;)
This not an Instructable of the usual kind as it less about actually making something for real but more about re-creating something that no longer exists in a complete form.
I have spent several weeks on the net trying to gather as much infos as possible, watched tons of videos and of course ripped my hair out sorting it all.
So if you are interested keep reading and stay updated on the progress over next few weeks or months.
For those only insterested in the models skip to step 3.
Step 1: Who Was Victor Schauberger?
Victor Schauberger was born in 1885 and Holzschlag, Austria and died there 1958.
A bit of info can be found on the english Wiki page and on the German Wiki page which has much more infos.
As it absolutely no problem to find tons of articles about his life and work I will make it short here (and refer to the WWW ;) ) and only focus on the Repulsine.
Fact and fiction...
The most famous stories in relation to Schaubergers work are not about water or proper ways of treating nature.
If you know the name you most likely know it because of claims one of his Repulsine devices had such a violent lift off that it crashed through the steel roof of the hangar it was placed in.
Some stories go as far as claiming it happened despite massive chains (used to tow tanks) connected to the Repulsine and anchored in the 2m thick concrete floor.
Although these stories are good reading there are no reliable sources for what really happened.
The only thing that is 100% sure is that all the materials and documents related to the Repulsine project were taken by the US forces after WW2.
Official claims of the time were that it was war material.
So, at least for this bit there will never be a "true" story.... :(
However, there is something very interesting for the UFO guys.
Schauberger started to work on the Repulsine quite early as a modified version of his "Home heating generator" (a device claimed to warm an entire house for the cost of a single lightbulb).
His inspiration for the work might have come from another inventor that created a "sucktion motor" for air planes.
Henri Coandă not only was famous for what we know today as the "Coanda Effect" but also for the plane he build.
Instead of using propulsion, like on any other propeller machine, Coanda used an engine that sucked the air in through a vortex and expeled it over a rotating disk back out.
When you check the two designs it is hard to deny certain similarities.
Before and during the WW2 times there have been a lot of UFO sightings in and around Austria.
All mention a weird looking disk, egg or the classic flying saucer.
Images and drawings of these sightings look pretty much identical to the shematics for the repulsine in it's later design stages.
Right after the war ended there have been no more "UFO" sightings in Austria, but the exact same flying things have been sighted in the US, mainly in the Arizona region.
Considering all of the Replusine work was taken to the US the timing of the sighting, or better their disappearance in Austria could make you think that Schaubergers Repulsine actually worked as planned.
Sadly again there is no 100% authentic image or witness report bringing bothe together and the US till today refuses to provide unaltered copies of Schaubergers original documents - all you get is a lot of pages with most of the content blacked out.
Think what you like about this one ;)
Victor Schaubergers grandson traveled to the US to see the last remaining model of a Repulsine during a test run.
Dr. Harold Puhoff of the Institute for advanced studies was impressed with the build quality and performance.
According to him even with modern technology it would hard to build it much better.
During these reserches it became apperent that several parts of the Repulsine are missing.
Some have been recreated from old images but the most vital parts remain lost.
These missing parts are what Victor Schauberger described as "energising devices and directors".
They might have been similar to what was used in his other inventions like the water energiser and purifier or the home heater but nothing is certain.
As I do not have any original images and copyright is always an issue I will not include any here, please check the WWW and you will find plenty of info about the things I talk about here.
Step 2: Is the Repulsine an UFO, a Flying Machine or Something Entirely Different?
Be my guest and make you own educated guess here.
With no evidence available anymore the conspiracy theorists will be happy but everyone interest in the real fact is left out.
I think after reading so much about it I tend to say his original intention was to build the next version of his home heater.
Like a perpetuum mobile the device was planned to run forever without using energy - in fact the motor used to start it was supposed to work as a generator once up to speed.
What you see on images about the Repulsine that is very old shows it as a flying machine in the classic "Roswell UFO" style.
Later images from the remaining parts only show the internals of the Repulsine but not the housing around it that gave it the UFO look.
Comparing those old images with some of his inventions like the heart pump show a very similar design.
My guess is that the outer shell of the Repulsine was similat to that of the heart pump.
Which means the the air coming out the part that we now know as the remaining Repulsine was directed into a vortex that concentrated in the center.
With air being sucked in from the top and the added "vortex energised" air coming partially back in from the bottom the only real outlet was a hole in the bottom center of the outer hull.
Imagine these vortex shapes on the wings of a plane during take off and landing - they curl from the wing tips inwards.
The same happened inside the hull - but the vortex was in three dimensions.
Like the Kudu horn or the famous sprial pipes Schauberger created, the air followed a specific flow and it is claimed that Schauberger perfected this design to the state where there was no friction anymore.
Todays claims about these features of friction free water transport are again inconclusive.
For example one study claims there was neither a gain in flow rate nor a reduction in the power levels the pump used.
Another study however claims that at certain flow speeds a resonance effect happens and that during that resonance the friction (and pump power) was reduced to a barely measurable low.
Problem with that resonance was to keep it resonating as even the slightest variations in temp, flow rate and even outside air pressure affected it.
It does not matter if like weird science, old technology or just nature in general - Victor Schauberger showed us a better way.
Too bad that most of it is long forgotten.
But if you check the Lily- or Harman- Impeller you see how other people make a good profit by re-using Schaubergers old designs.
Time to bring back more of his inventions! :)
Step 3: The Model So Far....
Here I will show the parts of my model once they are finnished and I am satisfied with the result.
Please keep in mind that they are not meant to be accurate in terms of being a replica but that they are meant to be a 3D printable model once all is finnished.
Please keep in mind that it is simply impossible to re-create the original if there are missing parts!
Also consider that the final pieces will be modified to make them printable on a normal 3D printer as I have no access to a fancy resin or powder printer.
The first objects to arrive here are the "wave disks":
Time to create the basic shape: About 6 hours to get it right.
Time to create the cuts for the air: About 3 weeks until satisfied with size, shape, angle and location.
Time to clean the model in Sketchup after cutting out the air vents: 2 weeks!
Reminds me that there are certainly better programs for the job....
(Tried cleaning and fixing with the usual external programs and webservices but either the filesize exploded or the shape was changed in spots required to fit the other parts of the model)
The bottom part was taken from a model on Thingyverse and served as the guide to the scale of other all other parts.
At first I tried to use the top part of that model as well but it was unsuited for the diffusor I have in mind.
The next part to come will be the the top diffusor that has to fit tight into the top disk.
Give me some time to create it ;)
Here is the cutout for the the diffusor.
I still need to desgin and match the outer body that mounts to the wave disks but it will follow ;)
And the finnished diffusor:
Here the one to be joined with the top wave disk:
Next will be the top air intake, which provides a challenge as there is little to zero info on it available.
But from the images I got I assume it must be similar to what was used in the home heater and other projects, so I will try it the same way.
Step 4: Printable Parts
We have a be nice policy.
Please be positive and constructive.
where find the 3d model for 3d printing repulsine?
