Repulsine - spin resonance?


Viktor’s device had a diamagnetic field do to the effect. Once he noticed that when sand is dragged along a streambed, it gives off piezio electric sparks. He was a most amazing man. According to Schauberger, a water and sand slurry was best for this charging effect. The Repulsine uses a cold water pipe to cool air in its chamber. But it is not absolutely required after spin-up. The shell becomes very hot as air is compressed from induced vertical updrafts surrounding the Repulsine. This vortex that forms above the Repulsine maintains its’ suction and continues to intake large quantities of atmosphere which is then cooled at the small base intake hole’s internal cyclone. In effect, the Repulsine, like Maxwell’s demon, separates the hot and cold air by conversion of external updraft momentum and uses it to draw more airflow to the Repulsine. Sailplanes are passive convection cell user’s...Viktor’s marvelous machine is active (!) - feeding back heat to enhance its own updraft. Where does the heat come from, as it is impossible to alter natural vertical flow without generating heat? That is simple momentum conversion. It heats itself!

It comes from the HILSCH-RANKINE tube effect. The shell gets very hot as the inside cools and implodes and the outside edge heats. You are actually pushing great quantities of air into the Repulsine, as well as forming suction above it. That is known as the "firestorm" effect. If you want to generate an updraft in a chimney you must warm it. The outer shell becomes very hot. The inside center cold. This creates a resonating flow effect. If this Repulsine did not oscillate between high and low pressure it would not intake as much air. That air can, by centrifugal compression at the shells’ rim, be directly converted into heat to maintain the effect. Look at the Hilsch-Rankine tube. It has the same exact effect. The mechanical flow of the external air (driven by natural solar convection currents) is a direct analogy to the compressed air used to drive the Hilsch-Rankine tube. The “Repulsine” is not internally powered. It is driven by external flow that is sub-ducted into its internal cyclone and generates a hot and cold region just as the Hilsch-Rankine tube does. The water and 1/20th horsepower motor is only used to start it.



Now, with all in place, you can do a first spin test. Instead of an attached motor, you can use the pressure exhaust of a large tank-type vacuum cleaner. It requires precise aim. Place the hose near the exhaust turbine and push air against the curved blades the same direction the air is meant to leave the plenum chamber. This is a simple reaction effect. The snail-shell hole is more then large enough for you to place the start-up air jet. Recall that model pulsejets were actually started with a bicycle pump. Now your unit is spinning! What happens next? Usually, very little will happen. It will spin of course, but, until the exact exhaust ratio and intake ratio is found, you can expect no miracles. The bearing races must be low-friction units. If you do it correctly, the unit will begin to heat up at its plenum shell circumference. Why (?) - because the internal wavy perforated discs and compressions on the shell rim are spinning air centrifugally. That can be seen directly by touching the top of any large-tank vacuum cleaner with a metal flange head. In fact all centrifugal air compressors or high pressure fans heat in this manner. Inside the plenum, the air is being separated into a center, or axle region, cold-zone and outer rim region hot-zone. Mechanical work from the upper exhaust disc is being used to separate these temperature regions. This effect is no different than is seen on the H-R tube! The only difference is that air is being spun on the unit by frictional interaction with the wavy disc set. In the H-R tube, it is from the mechanical energy, released as compressed air, and is swirled into a vortex tube. The exact same thermal separation occurs. The inner region is cold, and outer region is hot. That heat now contributes to a rising updraft vortex about the Repulsine. Recall in a calorimeter experiment, paddles are spun to heat water in a closed shell . One experiment is to then spray water at various temperatures into the shell. If it is done properly, it will assist in imploding the center cold air mass and greatly increasing the RPM. of the turbine. This is a science experiment of a lifetime.

Why does it work? As the work being done on the Repulsine internal plenum increases from the exhaust turbine drive shaft, the steel shell reaches a critical temperature level. At that point the rim air approaches several hundred degrees. The wavy discs prevent heat from easily moving from the rim to the center (that is one reason they are perforated and cannot be solid). The plenum will begin to alternately heat and cool as new air is drawn in at its base. If its core air trapped in between the wavy discs is cooled, the plenum velocity will increase. If it is heated by intake air, the velocity will slow. This effect is resonant and typical of the Repulsine operation. It is very hard to explain. Viktor claims, that any time you allow the core air of his Repulsine to heat and expand, it pulls the internal vortex wider apart! Next, as you intake cooler air, it snaps back together again. This is a phenomenon of thermo-mechanical resonance. Tesla coils use the very same principle.

The point is that your plenum will be driven off of induced external updrafts (as if a campfire) and off of a resonance caused by changes in the core vortex temperature! That is to say, the plenum chamber is like a child’s top. Any temperature change will cause the internal vortex (a vertical axis vortex centered about the drive axle) to expand and contract. The temperature changes must work in resonant fashion. Think of the child’s top being spun faster and faster, as they plunge its push rod up and down. This resonant expanding and contracting vortex bounces off the wavy rings much as ball bounces on a floor. Each time a little more energy is added. It is like stretching and contracting a rubber band around your fingers. When thermal mechanical vortex resonance is achieved, the implosion motor takes off. This is not an out-dated centrifugal air compressor. It is a chamber where any intake air is being converted into rotary motion. As the air vortex enlarges, it strikes the rim and cools. This causes it to bounce and return like a wave, to the center of the chamber (much like an echo reflecting off a hard surface). This compresses the center cold air and heats it, causing the wave front to once more expand.

That is why the wavy perforated discs are so important. They guide this echoing vortex band as it bounces from the rim to center and back again. To see what Schauberger saw, go to a circular water bath or tank (it must be a perfect circle). Put a Styrofoam disc at its center with a stick attached. Start to resonantly plunge the disk up and down. If you time it right, the wave crest will work with your plunges in harmony, as it bounces off the tank’s wall. This is exactly why those disks are wavy and perforated. They allow the vortex bounces to build up energy. Yes, you can argue that it wastes power. Actually it does not. The heat leaving the rim feeds back into the exhaust turbine updraft. You are amplifying this echo effect. Now the skeptic will begin to squirm in their seat. What good is this resonance effect? Sure, a Tesla coil makes a big spark, but that uses up electrical power even at high Q.


What makes a two-cycle motorcycle tail pipe exhaust expansion chamber work? Echo! That is correct. The principle that helps back pressure a two-cycle motorcycle engine is the exact same principle that feeds back energy in a Schauberger Repulsine implosion motor. It makes no difference. We can get mechanical work either way! A Sterling engine obtains mechanical work on both its cold cycle and hot cycle! We now have two defined reservoirs; a cold rim reservoir and a hot central intake reservoir. These reservoirs are maintained by external wind and sunlight. This is not a guess; it is a fact! A Stirling engine uses a displacer to shuttle an air mass between a hot and cold reservoir! Go to the fine Japanese Stirling engine pages found all over the web and you will soon understand this principle.

In the Repulsine, it is accomplished by the natural vortex echo inside of the chamber. This echo builds up our RPM. That is why the wavy discs are perforated. They must help spin the vortex but never stop its wave front echo. Think of that as a natural air displacer. Striking the rim cools the vortex and reaching the center heats it. The center bottom is hot from intake air ramming. Think of it this way before you stop reading this material. The echo bounce places our vortex over the center and then the rim region. That takes the place of the Stirling engine displacer. The vortex acts like a flywheel that stores the bounce energy. In effect, it is a simple Stirling engine hybrid that uses the expanding and contracting vortex as both a piston and a displacer, at the same time.

This is not difficult to understand. The Schauberger Repulsine is a new class of Stirling, atmospheric-feedback, hot-air motor. Schauberger’s genius removed the complex piston and displacer. They are replaced by a bouncing and expanding vortex and contracting vortex ring. If the reader takes away nothing more about the “Repulsine”, consider the following. IT is not a centrifugal air compressor. It is a new class of Stirling hot air engine, that converts a captive vortex into a piston and displacer that therefore shuttles between a hot center region, and a cold outer shell. This vortex also forms the Stirling Engine hybrid’s flywheel. In one simple gesture, Viktor removed the flywheel - the displacer and the piston - of a Stirling hot air engine - its closest thermo-mechanical cousin. By combining all of these elements, he simplified the Stirling engine, and, allowed it to directly feed back energy to an updraft. In other words, its own waste heat assists in increasing a natural external flow. No Stirling engine does that!

A final purpose of the wavy internal discs is to help "bounce" the vortex. It is similar to the 90-degree phase drive rod that activates the displacer. It forces the vortex wall back out to the rim. I realize that I said the rim is hot and it is. That is because it is constantly relieving itself of heat from the internal bouncing vortex. It is also cooled by the swirling external vortex. Without that, it is no longer a useful reservoir. In effect we have discovered a dynamic feedback Stirling Engine suited to extracting energy from a stationary external tornadic convection cell. This is not free energy...but I feel it is neglected physics. Only time and a little faith in Schauberger’s genius and commitment to relieving the suffering of mankind will tell.


In the “Phillips Technical Review Notes” we found references to an Air Core Betatron containing only a few kilograms of active magnetic flux material. That is to say the Phillips engineers had found a way to avoid the entire heavy iron superstructure used on a Betatron. It relied instead, like a Tesla coil, on resonance in heavy cables. To add, therefore to the list of things to avoid when constructing a Repulsine, I must now in all fairness add the Air Core Betatron effect. This means very simply, your Repulsine is capable of hard X-ray production from an internal current imploded with the thermo-mechanical rim resonance vortex bounce. To put it simply; the Repulsine at full resonance is a radiation source. It is possible that 50 thousand to 10 million electron volt-level radiation by-products, in the form of hard X-rays, will be present during operation. Any time you contract a charged electron cloud so that its magnetic field is cut, you can, and will accelerate electrons in the defined nature of a Betatron Particle Accelerator! It can and will emit high-energy particle radiation of the class known as High Energy Electrons and Hard X-rays. The Phillips’ Air Core Betatron proves a large ferromagnetic induction mass is not required for electron volt energy levels up to 9 MEV. Prolonged X-ray exposure is a certified tissue destroying process. For those “would’be” Nuclear Physicists out there, any doubts that the Repulsine is capable of Betatron particle acceleration will be quashed after reading about the “Phillips T.R. papers on their 9 MEV “Air Core Betatron””.

The final piece of the puzzle; The Repulsine's rim is resonantly cooled by thermally induced downdraft feedback, as the internal plenum flow expands for its re-coil or implosion echo. It is a surface effect. Hot internal centrifugal air induces a cold downdraft pulse that is in effect the capacitive analogy to our thermo-mechanical vortex resonance, taking place in the unit. Hot always attracts cold ...remember that! The Repulsine is unpredictable and dangerous, and, in an evacuated condition, is capable of Hard X-ray production. It is NOT a toy. It is best left in the hands of certified engineers and physicists!

My compliments and thanks to Mr. Robert (James) Bailey for his support, research data, notes and insight regarding construction of the working Repulsine model. The information that Mr. Bailey provided was absolutely invaluable in the compiling and research regarding construction and operation of a true Schauberger Repulsine. A heart felt "thank you" from all of us at ITP & GET. Also my unending respect and gratitude to Mr. Callum Coats, and Mr. Alick Bartholomew, (authors, publishers and writers) without whose work none of this website (or anything regarding Schauberger!) would be possible.

The conical and rifled (rippled) water-intake permits a variable step-up, creating a strong torque on the water, which, after entering the implosion turbine, will be intensified to such a pitch, that now its recoil (resonance) is driving it instead of the motor, as bio-technical applications always have a pull and push action. Such a turbine consists of tapered-down pipes with inside rifling which are bent into spirals.


Nikola Tesla( Experimented with wireless power, radio, and earth resonance.

The distant appliances, lamps and motors responded to the powerful pulsations, as if they were physically connected to the station by wire. A small house-like structure was established some 26 miles away from the station. In it, an aetheric power receiver was tuned to one of the rebroadcast rates. The 200 lamps housed within this structure, each of 50 watts rating, all remained brilliantly illuminated throughout the test runs. This apparently stimulated enough excitement and concern for word of this development to get back east.

Engineers were enraged. Those who had missed his most early shift from alternations to impulses, failed to comprehend the vast distinction between "stationary waves" and " standing waves". The quizzical use of specific terms such as these was a Tesla trademark, one designed to puzzle the minds of those who criticized him the most. With the exception of a very few colleagues who continually made related discoveries in aether physics, most academes had chosen to remain totally ignorant of the new study area. This for example was the case with the Teslian use of the term "frequency" and of "resonance" words which had completely different meanings for Tesla. Teslian "frequency" refers to the repetition of pulses per second. Teslian "resonance" refers to conditions in which aether flows with little or no resistance through systems, whether proximal or widely separated.

A Tesla coil secondary has its own particular electrical character determined in part by the length of that slender coiled wire. Like a guitar string of a particular length, it wants to vibrate at a particular frequency. The secondary is inductively plucked by the primary coil. The primary circuit consists of a pulsating high-voltage source (a generator or conventional step-up transformer), a capacitor, a spark gap, and the primary coil itself. This circuit must be designed so that it vibrates at a frequency compatible with the frequency at which the secondary wants to vibrate.

The primary circuit's frequency is determined by the frequency and voltage of the source, the capacity of the capacitor, the setting of the spark gap, and the character of the primary coil, determined in part by the length of its winding. Now when all these primary-circuit components are tuned to work in harmony with each other, and the circuit's resulting frequency is right for plucking the secondary in a compatible rhythmic manner, the secondary becomes at its terminal end maximally excited and develops huge electrical potentials, which if not put to work, boil off as a corona of bluish light or as sparks and streamers that jump to nearby conductors with crackling reports.

Unlike the conventional iron-core step-up transformer, whose core has the effect of damping vibrations, the secondary of the Tesla transformer is relatively free to swing unchecked. The pulsing from the primary coil has the effect of pushing a child in a swing. If it's done in a rhythmic manner at just the right moment at the end of a cycle, the swing will oscillate up to great heights. Similarly, with the right timing, the electrical vibration of the secondary can be made to swing up to tremendous amplitudes, voltages in the millions. This is the power of resonance.

Tesla invented his resonant transformer, as the Tesla coil is sometimes called, to power a new type of high-frequency lighting system, as his 1891 patent drawing shows. This was the first Tesla coil patent. There followed a series of other patents developing the device. All of these are for bipolar coils: both ends of the secondary are connected to the working circuit (usually lamps), as opposed to the mono polar format favored by today's basement builders in which the top is connected to a ball or other terminal capacitor, the bottom to ground. The mono polar format emerges later in patents for radio and wireless power, including Tesla's magnifying transmitter.

Tesla's patent shows that the deep cooling of conductors with agents like liquid air results in an extraordinary magnification of the oscillation in the resonating circuit. Imagine the performance of a super cooled Tesla coil. No electrocution. Since we tend to associate high voltage with possibly fatal electric shock it may be puzzling to learn that the output of a well-tuned Tesla coil, though in the millions of volts, is harmless. This is customarily thought to be because the amperage is low (it's not) or it's explained in terms of something called the skin effect, which means that the current travels over you instead of through. But the real reason is a matter of human frequency response. Just as your ears cannot respond to vibrations over about 30,000 cycles, or the eyes to light vibrations at or above ultra violet, your nervous system cannot be shocked by frequencies over about 2,000 cycles.

Earth Resonance:

Among the appealing features of Colorado Springs for Tesla were the region’s frequent and sensational electrical storms. For Tesla, lightning was a joyous phenomenon. Biographers report that, during storms back East, Tesla would throw open the windows of his New York lab and recline on a couch for the duration, muttering to himself ecstatically. In Colorado Springs he tuned in and tracked lightning storms using rudimentary radio receiving equipment. He thereby determined that lightning was a vibratory phenomenon, which set up standing waves bouncing within the earth at a frequency resonantly compatible with the earth's electrical capacity. This earth-resonant frequency, he reasoned, was the ideal frequency for wireless power transmission, and he tuned his ultimate magnifying transmitter accordingly.

The literature contains various reports on exactly what this frequency is. Some say 150 kilocycles, which would be at the upper range of the Colorado Springs transmitter. Others give frequencies considerably lower, 11.78 cycles, 6.8 cycles, frequencies Tesla's transmitter may have achieved harmonically. With reinforcement from the earth resonance, the power would actually increase in the process of transmission.

In one memorable experiment with the Colorado Springs transmitter, Tesla shot from the antenna ball veritable lightning bolts of 135 feet, producing thunder heard 15 miles distant, and, in the process, pulled so many amperes that he burned out the municipal generator. In another experiment he lit up wirelessly, at a distance of 26 miles from the lab, a bank of 10,000 watts worth of incandescent bulbs. Two years after Colorado Springs, Tesla applied for patent for the far more refined magnifying transmitter shown at the opening of this chapter, a patent that was not granted until a dozen years later.

In this patent he no longer speaks of energy broadcast through the upper strata of the atmosphere but of a grounded resonant circuit. Tesla predicted that his magnifying transmitter would prove most important and valuable to future generations, that it would bring about an industrial revolution and make possible great humanitarian achievements. Instead, as we shall see, the magnifying transmitter became Tesla's Waterloo.

Lighting Up The Sky:

Hold a fluorescent tube near a Tesla coil and it will light up in your hand. This is true of any tube or bulb with vacuum or rarefied gas. A more efficient way is to ground one end of the tube and put a length of wire as a sort of antenna on the other. Better yet, put a coil of wire that resonates with the secondary in series with the tube and ground and you have the optimal wireless power arrangement.

Tesla conducted many experiments with different arrangements like this, using on some occasions the widely available Edison filament incandescent, which lighted up more brilliantly than usual because of the effects of high frequencies on the bulbs rarefied interior. Inside his New York lab Tesla strung a wire connected to a Tesla coil around the perimeter of the room. Wherever he needed light he hung a gas tube in the vicinity of this high frequency conductor.

Tesla had a bold fantasy whereby he would use the principle of rarefied gas luminescence to light up the sky at night. High frequency electric energy would be transmitted, perhaps by an ionizing beam of ultraviolet radiation, into the upper atmosphere, where gases are at relatively low pressure, so that this layer would behave like a luminous tube. Sky lighting, he said, would reduce the need for street lighting, and facilitate the movement of ocean going vessels. The aurora borealis is an electrical phenomenon that works on this principle, the effects of cosmic eruptions such as those from the sun being the source of electric stimulation. I, for one, am grateful that this particular Tesla fantasy never materialized since it is difficult enough to see the stars with existing light pollution, and there might be undesirable biological impacts as well.


The Earth's Electrostatic Charge

Tesla's intent was to condense the energy trapped between the earth and its upper atmosphere and to transform it into an electric current. He pictured the sun as an immense ball of electricity, positively charged with a potential of some 200 billion volts. The earth, on the other hand, is charged with negative electricity. The tremendous electrical force between these two bodies constituted, at least in part, what he called cosmic energy. It varied from night to day and from season to season but it is always present.

The positive particles are stopped at the ionosphere and between it and the negative charges in the ground, a distance of 60 miles, there is a large difference of voltage - something on the order of 360,000 volts. With the gases of the atmosphere acting as an insulator between these two opposite stores of electrical charges, the region between the ground and the edge of space traps a great deal of energy. Despite the large size of the planet, it is electrically like a capacitor which keeps positive and negative charges apart by using the air as a non-conducting material as an insulator.

The earth has a charge of 96,500 coulombs. With a potential of 360,000 volts, the earth constitutes a capacitor of .25 farads (farads = coulombs/volts). If the formula for calculating the energy stored in a capacitor (E =1/2CV2) is applied to the earth, it turns out that the ambient medium contains 1.6 x 1011 joules or 4.5 megawatt-hours of electrical energy. In order to utilize this high-voltage energy you must do two things -- make an energy sink and then devise a way of making the "sink" oscillate.

"Zero-Point Energy?"

Such a "sink" has to be at a lower energy state than the surrounding medium and, for the energy to continually flow into it, the energy must be continually pumped out of it. Additionally, this "sink" must maintain a lower energy state while meeting the power requirements of the load attached to it. Electrical energy, watt-seconds, is a product of volts x amps x seconds. Because the period of oscillation does not change, either voltage or current has to be the variable in this system's energy equation. Bifilar wound coils are used in the system because a bifilar wound coil maximizes the voltage difference between its turns, the current is then minimized.

A coil in our system, then, will be set into oscillation at its resonant frequency by an external power source. During the "zero-point" portion of its cycle the coil will appear as one plate of a capacitor. As the voltage across the coil increases, the amount of charge it can siphon will increase. The energy that is taken into the coil through the small energy window (zero-point), call it what you will, appears to be the key to the success of this system. It is at this zero-point where energy is condensed into positive and negative components of current. When energy escapes from the "sink" the magnetic field collapses and a strong magnetic quake is created in it's wake. A properly tuned system can capture and convert radiant energy in such a prescribed arrangement.

baumgartner+pond book

Now for the first time, the secrets of this machine are available to you... This new manual presents a new technology. It is based on sonic vibrations which can be produced by a comparatively simple apparatus - The Tesla Oscillator. In the oscillators or transmitters described in this book, a resonance effect can be observed. Resonance appears to be an ever-expanding, magnifying effect with these transmitters. Very little input energy is required to set the device in motion and build that motion to tremendous levels of usable energy. The principle employed is called "Amplitude Modulated Additive Synthesis" by music industry engineers. We have included a full chapter on vibration physics to explain what happens.

Please note, that Walter Schauberger always said the his fathers technique is a resonance technique. This IS important!

Now, we must all think in terms of low pressure and cold processes. A vortex is a typical example of this. In the centre there is a low pressure (down to vacuum) and this also gives a temperature drop according to the gass laws. So we must learn how to generate a vortex or a system of vortices and how to maintain them in the most efficient way. Then we have an important lesson to make: You can not utilise a vortex directly! If you do so it will be destroyed and fade out.
What is possible to do is to use the EFFECT of the vortex as the low pressure or the high speed (high kintetic energy) of the central axis after the shaping of the vortex. This last example is utilised in the Heimkraftwerk and the Repulsin. In the Klimator it is the cooling effect that is used. Here we have a strange efffect according to V.S. In the Klimator when used as a heater the hot air did not go to the ceiling but it falled down to the floor!!???
Viktor meant that this is an other type of heat. I do not know if this was so but I have seen a Klimator working and it gets hot, and cold if you choose so.
This Klimator is made of Fritz Watzl in Austria not far from PKS. Sadly it was not made very good and by hand so he did not want us to make some copies...


the event with the klimator that melted at Siemens is recorded and also the exhauts cooling device at the Messeschmidtwerke in Augsburg.
Yes, the thoughts on resonance and standing wave are fruitful clues! Then, the "goal" is not always to generate a standing wave but in my meaning it is so in the case of the co rotating system (i.e. the Repulsin and Klimator).
It is possible to variate the volume of the cavity by changing the geometry of the inner "core" and in this way alter the "ground" frequency for the resonance.
It is also possible to generate a standing wave in the system by using a ludspeaker as an example. However, I am not shure if the energy is enough. Maybe this is why we must have the peripheral speed at or near the speed of sound. This is the energy source that gives the basic energy for the system. This energy is then amplified by the air flow and the vortices that twist together more and more when traveling from the centyre and out.
stewart: A question about preforming the air. Did VS preform the air to make sure there was enough of it to enter the machine? If so then why not open the machine up completely? This would make sure for adequate air supply.
I will have it milled out of Aluminium.
curt: Well, the support parts can be milled out from aluminium but the double membrane should be of copper!


John Keely and Nikola Tesla were able to tap into the universal divine energy

through their exploration of sound and electric resonances



Keely basically took advantage of the natural properties of waves which, when rectified or conjugated take the form of PUSH, BALANCE and PULL. Using resonance and phase conjugation Keely demonstrated a wealth of phenomena which included;

  • instantly exploding 3 drops of water to produce 29,000 PSI,
  • disintegrating quartz crystal using acoustics (rediscovered as shock waves currently being used to reduce garbage to a fine powder),
  • producing rotation by compound sound waves (patented in modern times by Panasonic as ultrasonic motors),
  • tapping into what he calls 'ether flows' to run his engines,
  • producing a glowing blue light in water using acoustics (now rediscovered as 'sonoluminescence'),
  • a compound motor that ran from many frequencies (later exploited by Tesla as his 'polyphase motor'),
  • demonstrating a pneumatic cannon powered by release and instant expansion of a bizarre plasma vapor,
  • an acoustic based flying machine that levitated and propelled itself in the presence of government witnesses and sundry other discoveries.
