@@markgeurts258 Thank you! Remember also I have learned so much along the journey so the older information even though it may not be accurate at times is very valuable. We are nearly finished with the final design for continuous use.
In an out of balance rotating assembly, the point of maximum eccentricity is not the heavy spot, but rather a little behind the heavy spot in the direction of rotation. That's because the centrifugal force is out through the heavy spot, but since the wheel has mass, by the time the wheel accelerates in the direction of force, the force has moved off in a different direction. Since the grinding is being done at maximum eccentricity a little behind the heavy spot, the mass removed shifts the heavy spot forward in the direction of rotation. Since you removed mass pretty close to the true heavy spot, you are presumably now less out of balance, but this technique effectively chases the heavy spot forward until the difference between the heavy spot and where you are grinding is less than your apparatus is able to resolve. That means that it will give you a good balance, but it cannot give you a perfect balance. It is also a little inefficient in that you are not removing just enough mass from the right spot to get the job done, but rather coming up to it from behind and removing mass asymptotically toward a true balance. So while this works acceptably, you'd think there'd be a better way.
Prior to the development of modern high speed apparatus static balancing was depended upon entirely and even now this is frequently the case. The steadily increasing tendency in the direction of high speed brought on the necessity of dynamic balancing and various forms of apparatus for this purpose were devised. The process I have invented enables this to be done quickly and with a high degree of accuracy and, briefly stated, consists in rotating the body to be balanced, yieldably supported, at a suitable speed and removing excess material from its heavier side by abrasion, until the desired degree of perfection of balance is attained. It might be naturally inferred that the contact of an emery or carborundum wheel with a rapidly whirling machine part would be productive of dangerous shocks and vibrations, and also that grinding at speeds much higher than the usual could now be satisfactorily accomplished. But although these theoretical assumptions appear sound, I have encountered no difficulties of this kind and have performed the operation with the greatest facility and success.
I’m not saying it doesn’t work (except to the extent of saying that it can’t work perfectly). I’m simply saying that if you consider what is actually going on, you are removing more material than is necessary from places where the problem doesn’t technically exist. There’s a lack of eloquence in it. I think it would help by starting by achieving the best static balance you can, since that technique either removes or adds mass as close as possible to where it is actually needed. Then to apply this dynamic approach alternating directions of rotation with a little bit of milling each way so that you approach the heavy spot from each direction, rather than to move the heavy spot forward and force yourself to chase it until you’ve closed the gap to a satisfactory degree. I suppose it’s possible the end result might be the same, but it would be an interesting experiment to find out.

@@phxerica you are spot on. The phase angle of the heavy side will not always be such that the heavy side is out. This is why in the patent Nikola Tesla says to do balancing st odd harmonics of the critical rpm. If you do it at even harmonics the light side will be out. But if you do it at odd harmonics the heavy side will always be out. This is the basic “rotating mass on a shaft with yieldable bearing supports” experiment. If you do balancing at the correct rpm you won’t be chasing the heavy side around. And can effectively balance damn near perfect if using different stiffer springs and shaft flexibility to do balancing at different RPMs as the system resonant frequency increases.
You example is simplistic and good for general explanations. I've been in Balancing Industry for decades and Force Measuring systems with automatic compensation is somewhat industry standard in today's market. Developing this test was surely fun.
I balanced my new 6.5" metal tesla turbine and the difference was night and day. Ill soon be demonstrating the difference. Also I had professionals balance my rotors and they can't come close to what I can do. If you know of a good place for me to get stuff balanced that doesn't suck I would love to know about it.
@@iEnergySupply Hello. As you know unbalance is mass displacement from axis. The less the displacement the better the balance. Only a few companies can easily and accurately measure to a displacement less than 5 micro-inches. This is calculated by formula e= U/W. e = displacement in microinches, U=unbalance level in ounces at 1" radius... W=rotor weight in ounces. If you are curious and have questions on balancing technology, I'll be glad to help jfranklin@hofmann-global.com
Interesting, When I did this I put it on a flexible arm but I did not figure out how to grind off the excess weight. I am now working on a titanium rotor and I think this idea will help me. Thank you and keep em spinning.
this was my first balancing prototype, since then I found that I had too much play on the flexible supports, I've since been using rubber races around the bearings, like tires.
@@iEnergySupply are you confident that the grinding is really balancing the rotor or have you calculated the offset of deflection due to the rotation? www.softschools.com/formulas/physics/torque_formula/59/
my thought on how this works, the unbalanced rotor and each springs create an oscillator. when the rpm hits the resonating frequency of that oscillator, the displacement in that direction is maximal. which is probably what happened at the end of the video... this would mean different spring rates are optimal for different rpm's. maybe you could compress the springs from the outside using a hydraulic system? also, how about mounting the rotor vertically so that the load on the springs is purely from the imbalance and keep the resonating frequencies of all springs as close as possible?
great suggestion to compress the springs to change the Yeald-ability I have since moved to much stiffer supports and it works great! Rubber or silicone works. Vertically would be nice, I believe it would help.
Just as a side note, the sand paper is for fine tuning because it's really slow. For the bulk of the material, I used the mill bit with ball nose. Otherwise it would have taken me a day to finish.
@@nikola.tesla.r.and.d.centreOh nvm. Tesla turbine is prettt much an energy transfer machine now. He try to copy magnetic attraction but didn't know it is non-matter system where matter interacts with aether rather than matter to matter interaction. It's a shame but at least he hid the secret in there. And tesla turbine NEEDS to be enclosed to trap the gas pressure so that the turbine can achieve synchronous speed to have maximum efficiency.
I am convinced of the near- ambient heat capture potential, and of the "air conditioning" value, of the TeslaTurbine device. The use of compressed air for renewable energy storage fascinates me. 1. Demonstrators of the technology should strive to have continuous monitoring of Temp, RH, barometric pressure and airflow rate, both before and after the gases enter the turbine. We need to sift dross from gems of RUclips like iEnergySupply's content, and attention to the correct measurement of these parameters is a starting point for developing wider uses for Tesla's invention and attracting proper funding. 2. If we are saying anything about conversion of energy into usable power, then volts and amps, under load, must also be monitored and recorded over time - for just the same reason. I can't be the only person who tunes out people who measure "No-load volts"! 3. Performance at times of changing input parameters is relevant, but not always possible under experimenter "RUclips enthusiastic Testing" so the process is best automated. I'm interested, for example, to have an answer to: How soon does a change in input temperature propagate to the cold side because this gives us performance data about the thermal inertial mass of the machine when operating. Moreover the #data from destructive testing (which features heavily in video ratings, and rightly so) * is not lost! *. Ice buildup has been demonstrated to be problematic. 4. I am less concerned about what happens in the microseconds as the fluid traverses a disk, because I cannot see how to measure the airflow characteristics without upsetting the laminar flow inside the turbine. But I can see great advantage in multistage expansion because Carnot tells us not only must it be more efficient if delta T is high across the entire system, but also that the longer time the fluid is entrained after each stage it is possible to supplement . 4. Arduino, and perhaps the maker community, has a role here. 3. I am, we have to be if this is a crowdsourced Global Change programme, focused on how to reach a workable, mobile generator, prototype demonstrator very quickly. Ideally the prototypes are cheap, locally produced, useful and instructive and can be adapted and modified by users such as schools, colleges and members of the Tesla Turbine communities that are global in reach. 5. Since the device works across a range of pressures, temperatures and flow rates (by its very nature, and by linear repetition of disks and spacers along an extended shaft and body of the turbine) I would think this a highly suitable project for both practical-commercial #CDReUseRecycling AND #3
Thanks again for sharing your research. I'm thinking that limiting the motion of the axel with rings of a reasonable size at each end might help save from catastrophe.
Good work. I have never heard of this technology but this video was informative on the general idea of how it works. Hopefully this technology is handy later on in your testing.
Tesla turbine is only a HINT. The REAL principle is in the principle - MAGNETIC ATTRACTION. He KNEW! He KNEW that magnetic attraction is the KEY to overunity. It creates kinetic energy from counterspace or negative space. He freaking knew. His hid the technology away from the illuminati! I found it! Tesla turbine - actually is a turbine booster. Using the adhesive between the air and the metal, the turbine itself is VIRTUALLY NOT draining the kinetic energy from the air, even though it does. The turbine simply rotates as it is pulled by the air. This slow down the air but increase pressure, allowing more adhesive force. Eventually, the turbine is in *synchronous* with the velocity of the air. Does the principle sound familiar? THAT'S RIGHT! The 3-phase no-load synchronous motor. Tesla turbine has ZERO TORQUE, in other words, no load can be added. Why did he build this? TO SHOW THE TRUE POWER OF MAGNETIC ATTRACTION. If no load can be added, it is connected to an ordinary steam turbine, BOOSTING IT. Free energy in disguise. What to do with 3-phase no load synchronous motor, externally excited? Configure the stator into a STEP-UP TRANSFORMER! Sorry for caption but I AM EXCITED for discovering this xD His life is most likely in danger.
Try magnetic bearings, less drag and no physical contact....no wear and higher speeds but must be balanced really good which Is a must anyhow. Good work and keep It up. 👍
That notch that was made for the light side, is being push down by the air flow. If there were 4 notches spaced out evenly , that should balance better
iEnergySupply Or in stead of cutting more spaces, you can put your bearings on a shaft, having a solid core base will compensate the push for the air. This would also balance out the wheel
uhh... buddy... the notch is there to UNBALANCE the piece.. it was perfectly balanced before he took a notch out. if he were to put more notches to balance, that completely defeats the purpose of unbalancing it.
Its cool to see this approach. I have two suggestions if they are any good im not sure : frequency of the whole assembly is not just simply dictated by the disbalanced wheel in the video and in case of large "wiggle" moments the wheel could have many rotations during one single "large wiggle" so probably it can happen easy that majority of the time indeed excess of the material will be grinded off compared to balanced portion of the wheel but both will be grinded like that in not particularly continuous way with accent that most of the time proper surface will be grinded, lets not exclude small frequencies of the oscillation while larger one is going on in the same time, its decent dynamic balance but its not perfect if perfection is chased so thing can achieve higher speeds. I think with your approach you count on disbalanced side will always hit first your drill bit and good side will not have a chance reaching that drill bit. And i think that happens but not always since frequency of the oscillation of the whole assembly is not always in sync with wheel rotational position. Suggestion one is probably quite complex to be done where oscillation of the whole assembly has exact matching speed with the wheel rotation. Suggestion 2 is simplified example: "push the sandpaper" onto the wheel and at all moments it has firm contact with the wheel(effect one :it will cut down unnecessary amplified vibrations) by spring force where idea is simple, more the wheel pushes toward the spring the greater the sand paper grinding in that moment is removing the unwanted material(side effect : you grinding the whole thing so proper preplanning of the wheel dimensions is needed accounting for that loss of the wheel diameter, as also springs on your video and springs that i am talking about has memory and will kick back at random position hence grinding where is not needed). One more suggestion is firstly grind X and Z where wheel can oscilate only back and forth and springs need to be guided firmly by their own casing and bearings of the shaft are fixed onto those springs- these axis are planar and distance/movement axis(i suggest rotating the wheel at different speeds/passes of the grinding just because we have greater chances grinding excess of the material properly-reason is that different speeds will have different planar x and z axis where they want to push and since we are forbidding up and down movement we would miss some of those forces that we want to grind off, so different speeds gives us a better chance of encountering excess of the material on our springs axis ,probably pulsing the air pressure at particular angle(and changing that from time to time) has a chance of shifting the excess material "wiggle" into desired direction>toward our tool). After diameter of the wheel is corrected with previous step then you can use your approach where whole assembly is suspended where mainly what should be grinded is the Y axis(rotational) and again Z axis(but this time it is whole assembly and is not distance but rotational axis) or in other words the skew of the whole assembly as seen from your video is exactly what i mean by saying this rotational axis and should be the last step, i just think that speed of the grinding process will be faster and slightly more precise with two steps/two machines. So if i can pull some conclusion it would be : use different speeds, pulse the speed at particular moments so the wobble is poked with grinder from many perspectives, and use very strong springs since large wiggle is not needed and amplification of the wiggle is also not needed, i think if springs get fast as possible into their position is beneficial and assembly will vibrate anyway, and thats how large chunks of large disbalanced materials can be grinded fast which gives us a speed of grinding, then we change the springs toward weaker and weaker ones and with each pass we are dealing with more and more refined tweaks < point with this is > at any moment we have minimal wiggle which allows us moving the grinder more aggressive and saving on time, it not excluded that this dynamic springs approach changes the precision towards better. I started looking at these turbines 2 days ago and saw this dynamic balancing few moments ago so i didn't have'd much time thinking about all of this but its just what my logic in brain provides me and i wanted to help at least with sparking the imagination of what can be done if nothing else. Cheers hehe!
Now when i think even more about it (inspired by this video) i think electromagnetic spring the solenoid would do much better job and would not produce kick back errors that springs are doing(hence not allowing perfection), but proper solenoid opens many doors of what vibrations you want to allow, how long they can be, measuring the current in solenoids and so forth can talk to other solenoids in the system and tell the story of excess material to the software. Only downside i see with "electrical springs" is single one which is making the g.damn thing hahahaah(quite a task lol)
Great suggestions here, my solution was balancing at higher speeds and using rubber rings around the bearings. Seems to work really good. Please read tesla's patent NIKOLA TESLA BRITISH PATENT 186,799 - PROCESS OF AND APPARATUS FOR BALANCING ROTATING MACHINE PARTS teslauniverse.com/nikola-tesla/patents/british-patent-186799-process-and-apparatus-balancing-rotating-machine-parts Let me know if you find anything interesting in there that may add insights.
@@iEnergySupply Ah that's smart using the rubber, simple solution for complex problem i didn't think of that. Yeah i can totally see why it works better then springs(springs=sharp/strong force with memory that has tendency to sort of be buoyant hence since stubborn has its own frequency for the mechanical work and disturbing the shaft frequency, rubber= slow memory weak spring force(on its own) that does not have tendency to be buoyant hence not introducing additional frequency to the system but rather conforming in gentle way to the wheels shaft forces, and since rubber atoms has strong force of sticking together that should result in wherever rubber rings get stretched the other side/rather surrounding material gets pulled and with the speed and only with the speed of the shaft dealing the forces(now it becomes fast reactive conforming force driven by the force that acts upon it(this is more of an damper instead of the spring isnt O.o))). Thank you for sharing the knowledge with everyone thru the video as also for the paper that i'm going gladly to consume now with the morning coffee ahah.
@@iEnergySupply I did look at the paper. I can notice his simple convenient adjustable reading apparatus which is just a needle mounted onto the bearing from the shaft, with the weight adjustable per height and by moving that weight away from the shaft i think needle is less prone to show miniscule vibrations(since higher torque is needed to move the needle and just larger vibrations will manage to do that) so instead of adjustable springs he can use one single spring stiffness or smarter in your case rubber but the reading still can be fine tuned in order so we can understand how much excess material we have remaining and how big it is
I think i got it about critical thingy. Lets just say that main goal as also the trouble with balancing is knowing when to apply the grinding. And from there i can put few thoughts into it by considering it as important part of balancing. One thing that is clear to me is wheel 360 turn per 1 unit of time must be less or double the maximum amplitude of the frequency of the assembly vibration per same unit of time(not related but essential : here we must have lesser "shaking" frequency of the shaft compared to the maximum frequency of memory of the rubber you are using-to avoid that kickback errors that are very noticeable in the springs and miniscule in the rubber< this is sort of how fast i can spin the shaft, thats the maximum which is yours memory frequency of the material+shape you are using to allow bearings to shake, your shaft "springs" must not have delay behind the shaft wiggle and if they are faster thats fine) that you aiming for(we will have many different points on the periphery of the wheel that has different excess of the mass so its completely arbitrary and random hence not convinient grinding all that randomness at once, hence we should tweak our measuring instrument(Tesla provided) to read firstly larger shaft frequencies/ just one, the largest one, by adjusting our weight so far away from the needle center that it does not show almost any movement if any, and then bringing the weight just slightly back so we can pickup the first mass displacement< why doing this since naturally grinder will remove eventually everything(yet not in perfect manner)? Well its not obvious but there is a reason(trying the perfect manner) which is improving the grinding process to happen at pulses/only when we need it hence measuring instrument can show us once it stabilises when we are finished grinding our target excess of the mass without relying on the sound and eye sight on the machine, also instrument allows us tracking our grinding process even if machine is enclosed into some chassis as Tesla was doing(as i understand he did that in order to have same/or close to conditions while grinding that will simulate real environment turbine will spin in- i dont think it is essencial doing it but is nice safety by just removing "over-planning it" and avoiding calculating many factors-so instead just grind it in the environment in which turbine will be used where crazy calculations are not needed but instead we can simply observe and conclude how turbine will perform in real setup)). With this step we have constant single mass detected that we are chasing to remove from the wheel perimeter(main point is we avoid grinding the good part of the wheel-we slowly going there with debugging how to do it). Critical is (that this aimed oscillation maximum distance shaft can oscillate at and together in the same time as marked wheel point arrives to the same local to them respective points in space and the same time). Matching the amplitude needle of the shaft with wheel revolving point i think can be done mechanically and we could easy detect if two are out of synch in which case we move away the grinder and we adjust the speed again. Now to couple the grinding tool and provide opposing frequency to him and matching shaft frequency where highest amplitude of the shaft frequency will be the highest amplitude of the frequency of grinding tool going toward each other: mechanically bearing of the shaft is connected to the grinding tool with any mechanical assembly that will provide opposing force such as "double elbow" or any other will do. This way we are having our own pulses of the grinding instead of relying on the static grinder and excess of material hopefully and only them hitting the grinder. Now this coupling can also pulse in wrong time(yes frequency of the shaft shaking is directly connected to the grinder so grinder always have same opposing frequency) but this "matching pulse grind" system will suffer fromt he same problem as soon as we step out of the wheel speed rotation + frequency of the shaft. thats why it is essential looking at that shaft frequency meter + wheel rpm. < how exactly wheel rpm together with random mass displacements on it colaborate to produce particular frequency is beyond my brain simulations so things like that can be learned by observation and looking at the machine itself, so my suggestions or attempts of help cut short there.
Wouldn't it be better to have a blower from both directions, 180 degrees to each other, like Tesla recommended? As in, wouldn't this not be a perfect balance, because the propelling force is coming only from one side and that plays a role in the balancing?
you should try magnetic bearing levitation, and so... you should create an electronic balancing system with arduino for each bearing, and with a series of sensors that read the imbalance, and make the balance correction by energizing or de-energizing the magnetization (increasing or decreasing the magnetic power) so as to constantly correct it ... I hypothesize that with such a system, you could obtain levitation magnetic bearings, with high precision balance ... this is at least the theory .. then it would take practice .. creating the self-balancing algorithm ...
Good idea! I have balanced with magnetic bearings in the past, and unfortunately I ran into a problem because my magnetic bearings were interfering with my generator magnet on the same shaft. We are going to re-visit this concept in the future as we are predicting there will be no need for a generator. The Turbine in vacuum is capable of generating electricity via electrostatics. This we also need a metal rotor for.
@@iEnergySupply My idea actually came from another video of yours where you did tests with magnetic levitation bearings, not only from your video, actually I'm doing research on youtube to see this type of stuffs and in fact I found your channel through these searches. But you are also right, the imbalance comes from magnetic interference ... something would also be needed that insulates the levitation bearings from interference, and in this I am totally ignorant, is there any material or method that insulates-limits magnetic interference ???
Also have you look into Gerard morin drive ? mabe some of his stuff can help your electrical parts of the problem,, if what he was working a couple year ago is truly working,,it is actually what you need for your turbine,, its the generator and electrical parts of your problem.
A little bit, my new balancing apparatus is better and the air doesn't affect it. If you can spin it up to high speeds while you balance it it works better.
@@iEnergySupply what a reply... that doesn't answer his question in the slightest. WHERE and HOW was the material removed, to resolve dynamic balance? your answer was to "when" which was not a question that was asked. this is middle school stuff. read the question BEFORE answering
once you can make or get your hand onto magnetic bering,,its actually not too hard to make,, your thing will work better than spring,, as modern mechanical battery use magnet levitation bering in a vacuum .
"i had problems with plastic exploding at 40,000 plus rpm", like no shit it does, if you spin anything unbalanced to 40,000 rpm bad things are gonna happen

Thank you! Good idea thinking about the grinding wheels, I've thought about it before but one thing to note with the grinder wheels is they can't take as high rpm as some of the better materials out there. Also they need exhaust holes in the center of the disks. We will be giving more construction details soon, and the best materials to use for the disks. It's actually quite cheap to pay a company out there with a water jet to cut you're disks. I can give cad drawings that you can hand over to them in the future.
iEnergySupply would love to further communicate said cad drawings please contact joeylawell1234@gmail.com the fact researchers like you take the time of day to respond to some kid on the internet is the reason this community exists.
That’s great, because there are a lot of lexan rotors that don’t need to retain any particular size or shape being used in industrial applications. 😂😂😂😂😂
@@iEnergySupply My point was that there is no real practical application for this type of balancing. It's an interesting little experiment, but that's all. By the way, it would work a lot better if you didn't suspend the bearings in springs. The springs' result is to make a phase angle impossible to determine, either by vibration equipment or by the shaving off of eccentricity in this method. What that means is that more often than not, you'll be shaving off something other than the heavy side. Try it again mounted in a rigid frame and you'll see. Or more accurately you *won't* see (any movement) but you will be able to shave off the actual heavy side only. It will be much faster and much more accurate.
Actually, that method is described in detail by Nicola Tesla as a requirement for his turbine design. According to the frequency and resonance, you could do static balance, dynamic or both. But I never thought of that size fact.... Would it work better (size wise or less vibration), if you first statically balance it with weights (or cutouts) and after that use this grinding method?@@DavidFerree54 @iEnergySupply
Or, you could just use a real balancing machine and have the job done in about 10 minutes. And, you'd actually know what tolerance you achieved. This is both silly and dangerous.
I have since improved the apparatus. Also I had some professionally balanced and the professionals seem to have difficulty achieving a good balance when ran at high speeds. It's important for me to understand all the areas of this research and experimentation is the fastest way I've found to learn.

Thumbs up.
Thanks for the advice!
In an out of balance rotating assembly, the point of maximum eccentricity is not the heavy spot, but rather a little behind the heavy spot in the direction of rotation. That's because the centrifugal force is out through the heavy spot, but since the wheel has mass, by the time the wheel accelerates in the direction of force, the force has moved off in a different direction. Since the grinding is being done at maximum eccentricity a little behind the heavy spot, the mass removed shifts the heavy spot forward in the direction of rotation. Since you removed mass pretty close to the true heavy spot, you are presumably now less out of balance, but this technique effectively chases the heavy spot forward until the difference between the heavy spot and where you are grinding is less than your apparatus is able to resolve. That means that it will give you a good balance, but it cannot give you a perfect balance. It is also a little inefficient in that you are not removing just enough mass from the right spot to get the job done, but rather coming up to it from behind and removing mass asymptotically toward a true balance.

I balanced my new 6.5" metal tesla turbine and the difference was night and day. Ill soon be demonstrating the difference. Also I had professionals balance my rotors and they can't come close to what I can do. If you know of a good place for me to get stuff balanced that doesn't suck I would love to know about it.
@@iEnergySupply Hello. As you know unbalance is mass displacement from axis. The less the displacement the better the balance. Only a few companies can easily and accurately measure to a displacement less than 5 micro-inches. This is calculated by formula e= U/W. e = displacement in microinches, U=unbalance level in ounces at 1" radius... W=rotor weight in ounces. If you are curious and have questions on balancing technology, I'll be glad to help jfranklin@hofmann-global.com
@@jefffranklin7439 Thank you.
Holy crap, that is genius!
thanks! I've since improved upon the tequnique.
Interesting, When I did this I put it on a flexible arm but I did not figure out how to grind off the excess weight. I am now working on a titanium rotor and I think this idea will help me. Thank you and keep em spinning.
this was my first balancing prototype, since then I found that I had too much play on the flexible supports, I've since been using rubber races around the bearings, like tires.
@@iEnergySupply are you confident that the grinding is really balancing the rotor or have you calculated the offset of deflection due to the rotation?
www.softschools.com/formulas/physics/torque_formula/59/
my thought on how this works, the unbalanced rotor and each springs create an oscillator.
when the rpm hits the resonating frequency of that oscillator, the displacement in that direction is maximal.
which is probably what happened at the end of the video...
this would mean different spring rates are optimal for different rpm's.
maybe you could compress the springs from the outside using a hydraulic system?
also, how about mounting the rotor vertically so that the load on the springs is purely from the imbalance and keep the resonating frequencies of all springs as close as possible?
great suggestion to compress the springs to change the Yeald-ability I have since moved to much stiffer supports and it works great! Rubber or silicone works. Vertically would be nice, I believe it would help.
Very interesting indeed. I never seen a balance setup like that before
The new one is a little different, much better though, stay tuned.
Just as a side note, the sand paper is for fine tuning because it's really slow. For the bulk of the material, I used the mill bit with ball nose. Otherwise it would have taken me a day to finish.
Why are you building the WRONG tesla turbine? And the secret of overunity is in the principle of how tesla turbine work - MAGNETIC ATTRACTION.
@@nikola.tesla.r.and.d.centreOh nvm. Tesla turbine is prettt much an energy transfer machine now. He try to copy magnetic attraction but didn't know it is non-matter system where matter interacts with aether rather than matter to matter interaction. It's a shame but at least he hid the secret in there.
And tesla turbine NEEDS to be enclosed to trap the gas pressure so that the turbine can achieve synchronous speed to have maximum efficiency.
Ill be using aluminum disks soon. Thank you for your comments!
I am convinced of the near- ambient heat capture potential, and of the "air conditioning" value, of the TeslaTurbine device. The use of compressed air for renewable energy storage fascinates me.
1. Demonstrators of the technology should strive to have continuous monitoring of Temp, RH, barometric pressure and airflow rate, both before and after the gases enter the turbine. We need to sift dross from gems of RUclips like iEnergySupply's content, and attention to the correct measurement of these parameters is a starting point for developing wider uses for Tesla's invention and attracting proper funding.
2. If we are saying anything about conversion of energy into usable power, then volts and amps, under load, must also be monitored and recorded over time - for just the same reason. I can't be the only person who tunes out people who measure "No-load volts"!
3. Performance at times of changing input parameters is relevant, but not always possible under experimenter "RUclips enthusiastic Testing" so the process is best automated. I'm interested, for example, to have an answer to: How soon does a change in input temperature propagate to the cold side because this gives us performance data about the thermal inertial mass of the machine when operating. Moreover the #data from destructive testing (which features heavily in video ratings, and rightly so) * is not lost! *. Ice buildup has been demonstrated to be problematic.
4. I am less concerned about what happens in the microseconds as the fluid traverses a disk, because I cannot see how to measure the airflow characteristics without upsetting the laminar flow inside the turbine. But I can see great advantage in multistage expansion because Carnot tells us not only must it be more efficient if delta T is high across the entire system, but also that the longer time the fluid is entrained
after each stage it is possible to supplement .
4. Arduino, and perhaps the maker community, has a role here.
3. I am, we have to be if this is a crowdsourced Global Change programme, focused on how to reach a workable, mobile generator, prototype demonstrator very quickly. Ideally the prototypes are cheap, locally produced, useful and instructive and can be adapted and modified by users such as schools, colleges and members of the Tesla Turbine communities that are global in reach.
5. Since the device works across a range of pressures, temperatures and flow rates (by its very nature, and by linear repetition of disks and spacers along an extended shaft and body of the turbine) I would think this a highly suitable project for both practical-commercial #CDReUseRecycling AND

@@nikola.tesla.r.and.d.centre Hello
Thanks again for sharing your research. I'm thinking that limiting the motion of the axel with rings of a reasonable size at each end might help save from catastrophe.
your absolutely right, I did just that with the new one, but used rubber spokes instead of springs.
Good work. I have never heard of this technology but this video was informative on the general idea of how it works. Hopefully this technology is handy later on in your testing.
Thank's, I've never built a prototype of Nikola Tesla's that I didn't find useful.
Tesla turbine is only a HINT. The REAL principle is in the principle - MAGNETIC ATTRACTION. He KNEW! He KNEW that magnetic attraction is the KEY to overunity. It creates kinetic energy from counterspace or negative space. He freaking knew. His hid the technology away from the illuminati! I found it!
Tesla turbine - actually is a turbine booster. Using the adhesive between the air and the metal, the turbine itself is VIRTUALLY NOT draining the kinetic energy from the air, even though it does. The turbine simply rotates as it is pulled by the air. This slow down the air but increase pressure, allowing more adhesive force. Eventually, the turbine is in *synchronous* with the velocity of the air.
Does the principle sound familiar? THAT'S RIGHT!
The 3-phase no-load synchronous motor. Tesla turbine has ZERO TORQUE, in other words, no load can be added. Why did he build this? TO SHOW THE TRUE POWER OF MAGNETIC ATTRACTION.
If no load can be added, it is connected to an ordinary steam turbine, BOOSTING IT. Free energy in disguise.
What to do with 3-phase no load synchronous motor, externally excited? Configure the stator into a STEP-UP TRANSFORMER!
Sorry for caption but I AM EXCITED for discovering this xD
His life is most likely in danger.
Spread the truth. We need it OUT!
Try magnetic bearings, less drag and no physical contact....no wear and higher speeds but must be balanced really good which Is a must anyhow.
Good work and keep It up. 👍
As you move forward into metal rotors, will this balancing still need to be done if the parts are laser cut ?
absolutely, balancing is almost unavoidable.
That notch that was made for the light side, is being push down by the air flow. If there were 4 notches spaced out evenly , that should balance better
You're absolutely correct! Thanks for the good advice!
iEnergySupply
My pleasure! And thank you for posting
iEnergySupply
My pleasure! And thank you for posting
iEnergySupply
Or in stead of cutting more spaces, you can put your bearings on a shaft, having a solid core base will compensate the push for the air. This would also balance out the wheel
uhh... buddy... the notch is there to UNBALANCE the piece.. it was perfectly balanced before he took a notch out. if he were to put more notches to balance, that completely defeats the purpose of unbalancing it.
Can we see the final result on the balanced wheel?
Its cool to see this approach. I have two suggestions if they are any good im not sure : frequency of the whole assembly is not just simply dictated by the disbalanced wheel in the video and in case of large "wiggle" moments the wheel could have many rotations during one single "large wiggle" so probably it can happen easy that majority of the time indeed excess of the material will be grinded off compared to balanced portion of the wheel but both will be grinded like that in not particularly continuous way with accent that most of the time proper surface will be grinded, lets not exclude small frequencies of the oscillation while larger one is going on in the same time, its decent dynamic balance but its not perfect if perfection is chased so thing can achieve higher speeds. I think with your approach you count on disbalanced side will always hit first your drill bit and good side will not have a chance reaching that drill bit. And i think that happens but not always since frequency of the oscillation of the whole assembly is not always in sync with wheel rotational position. Suggestion one is probably quite complex to be done where oscillation of the whole assembly has exact matching speed with the wheel rotation. Suggestion 2 is simplified example: "push the sandpaper" onto the wheel and at all moments it has firm contact with the wheel(effect one :it will cut down unnecessary amplified vibrations) by spring force where idea is simple, more the wheel pushes toward the spring the greater the sand paper grinding in that moment is removing the unwanted material(side effect : you grinding the whole thing so proper preplanning of the wheel dimensions is needed accounting for that loss of the wheel diameter, as also springs on your video and springs that i am talking about has memory and will kick back at random position hence grinding where is not needed). One more suggestion is firstly grind X and Z where wheel can oscilate only back and forth and springs need to be guided firmly by their own casing and bearings of the shaft are fixed onto those springs- these axis are planar and distance/movement axis(i suggest rotating the wheel at different speeds/passes of the grinding just because we have greater chances grinding excess of the material properly-reason is that different speeds will have different planar x and z axis where they want to push and since we are forbidding up and down movement we would miss some of those forces that we want to grind off, so different speeds gives us a better chance of encountering excess of the material on our springs axis ,probably pulsing the air pressure at particular angle(and changing that from time to time) has a chance of shifting the excess material "wiggle" into desired direction>toward our tool). After diameter of the wheel is corrected with previous step then you can use your approach where whole assembly is suspended where mainly what should be grinded is the Y axis(rotational) and again Z axis(but this time it is whole assembly and is not distance but rotational axis) or in other words the skew of the whole assembly as seen from your video is exactly what i mean by saying this rotational axis and should be the last step, i just think that speed of the grinding process will be faster and slightly more precise with two steps/two machines. So if i can pull some conclusion it would be : use different speeds, pulse the speed at particular moments so the wobble is poked with grinder from many perspectives, and use very strong springs since large wiggle is not needed and amplification of the wiggle is also not needed, i think if springs get fast as possible into their position is beneficial and assembly will vibrate anyway, and thats how large chunks of large disbalanced materials can be grinded fast which gives us a speed of grinding, then we change the springs toward weaker and weaker ones and with each pass we are dealing with more and more refined tweaks < point with this is > at any moment we have minimal wiggle which allows us moving the grinder more aggressive and saving on time, it not excluded that this dynamic springs approach changes the precision towards better. I started looking at these turbines 2 days ago and saw this dynamic balancing few moments ago so i didn't have'd much time thinking about all of this but its just what my logic in brain provides me and i wanted to help at least with sparking the imagination of what can be done if nothing else. Cheers hehe!
Now when i think even more about it (inspired by this video) i think electromagnetic spring the solenoid would do much better job and would not produce kick back errors that springs are doing(hence not allowing perfection), but proper solenoid opens many doors of what vibrations you want to allow, how long they can be, measuring the current in solenoids and so forth can talk to other solenoids in the system and tell the story of excess material to the software. Only downside i see with "electrical springs" is single one which is making the g.damn thing hahahaah(quite a task lol)
Great suggestions here, my solution was balancing at higher speeds and using rubber rings around the bearings. Seems to work really good. Please read tesla's patent
NIKOLA TESLA BRITISH PATENT 186,799 - PROCESS OF AND APPARATUS FOR BALANCING ROTATING MACHINE PARTS
teslauniverse.com/nikola-tesla/patents/british-patent-186799-process-and-apparatus-balancing-rotating-machine-parts
Let me know if you find anything interesting in there that may add insights.
@@iEnergySupply Ah that's smart using the rubber, simple solution for complex problem i didn't think of that. Yeah i can totally see why it works better then springs(springs=sharp/strong force with memory that has tendency to sort of be buoyant hence since stubborn has its own frequency for the mechanical work and disturbing the shaft frequency, rubber= slow memory weak spring force(on its own) that does not have tendency to be buoyant hence not introducing additional frequency to the system but rather conforming in gentle way to the wheels shaft forces, and since rubber atoms has strong force of sticking together that should result in wherever rubber rings get stretched the other side/rather surrounding material gets pulled and with the speed and only with the speed of the shaft dealing the forces(now it becomes fast reactive conforming force driven by the force that acts upon it(this is more of an damper instead of the spring isnt O.o))). Thank you for sharing the knowledge with everyone thru the video as also for the paper that i'm going gladly to consume now with the morning coffee ahah.
@@iEnergySupply I did look at the paper. I can notice his simple convenient adjustable reading apparatus which is just a needle mounted onto the bearing from the shaft, with the weight adjustable per height and by moving that weight away from the shaft i think needle is less prone to show miniscule vibrations(since higher torque is needed to move the needle and just larger vibrations will manage to do that) so instead of adjustable springs he can use one single spring stiffness or smarter in your case rubber but the reading still can be fine tuned in order so we can understand how much excess material we have remaining and how big it is
I think i got it about critical thingy. Lets just say that main goal as also the trouble with balancing is knowing when to apply the grinding. And from there i can put few thoughts into it by considering it as important part of balancing. One thing that is clear to me is wheel 360 turn per 1 unit of time must be less or double the maximum amplitude of the frequency of the assembly vibration per same unit of time(not related but essential : here we must have lesser "shaking" frequency of the shaft compared to the maximum frequency of memory of the rubber you are using-to avoid that kickback errors that are very noticeable in the springs and miniscule in the rubber< this is sort of how fast i can spin the shaft, thats the maximum which is yours memory frequency of the material+shape you are using to allow bearings to shake, your shaft "springs" must not have delay behind the shaft wiggle and if they are faster thats fine) that you aiming for(we will have many different points on the periphery of the wheel that has different excess of the mass so its completely arbitrary and random hence not convinient grinding all that randomness at once, hence we should tweak our measuring instrument(Tesla provided) to read firstly larger shaft frequencies/ just one, the largest one, by adjusting our weight so far away from the needle center that it does not show almost any movement if any, and then bringing the weight just slightly back so we can pickup the first mass displacement< why doing this since naturally grinder will remove eventually everything(yet not in perfect manner)? Well its not obvious but there is a reason(trying the perfect manner) which is improving the grinding process to happen at pulses/only when we need it hence measuring instrument can show us once it stabilises when we are finished grinding our target excess of the mass without relying on the sound and eye sight on the machine, also instrument allows us tracking our grinding process even if machine is enclosed into some chassis as Tesla was doing(as i understand he did that in order to have same/or close to conditions while grinding that will simulate real environment turbine will spin in- i dont think it is essencial doing it but is nice safety by just removing "over-planning it" and avoiding calculating many factors-so instead just grind it in the environment in which turbine will be used where crazy calculations are not needed but instead we can simply observe and conclude how turbine will perform in real setup)). With this step we have constant single mass detected that we are chasing to remove from the wheel perimeter(main point is we avoid grinding the good part of the wheel-we slowly going there with debugging how to do it). Critical is (that this aimed oscillation maximum distance shaft can oscillate at and together in the same time as marked wheel point arrives to the same local to them respective points in space and the same time). Matching the amplitude needle of the shaft with wheel revolving point i think can be done mechanically and we could easy detect if two are out of synch in which case we move away the grinder and we adjust the speed again. Now to couple the grinding tool and provide opposing frequency to him and matching shaft frequency where highest amplitude of the shaft frequency will be the highest amplitude of the frequency of grinding tool going toward each other: mechanically bearing of the shaft is connected to the grinding tool with any mechanical assembly that will provide opposing force such as "double elbow" or any other will do. This way we are having our own pulses of the grinding instead of relying on the static grinder and excess of material hopefully and only them hitting the grinder. Now this coupling can also pulse in wrong time(yes frequency of the shaft shaking is directly connected to the grinder so grinder always have same opposing frequency) but this "matching pulse grind" system will suffer fromt he same problem as soon as we step out of the wheel speed rotation + frequency of the shaft. thats why it is essential looking at that shaft frequency meter + wheel rpm. < how exactly wheel rpm together with random mass displacements on it colaborate to produce particular frequency is beyond my brain simulations so things like that can be learned by observation and looking at the machine itself, so my suggestions or attempts of help cut short there.
Wouldn't it be better to have a blower from both directions, 180 degrees to each other, like Tesla recommended? As in, wouldn't this not be a perfect balance, because the propelling force is coming only from one side and that plays a role in the balancing?
So intuitive. Awesome
you should try magnetic bearing levitation, and so...
you should create an electronic balancing system with arduino for each bearing, and with a series of sensors that read the imbalance, and make the balance correction by energizing or de-energizing the magnetization (increasing or decreasing the magnetic power) so as to constantly correct it ...
I hypothesize that with such a system, you could obtain levitation magnetic bearings, with high precision balance ...
this is at least the theory .. then it would take practice .. creating the self-balancing algorithm ...
Good idea!
I have balanced with magnetic bearings in the past, and unfortunately I ran into a problem because my magnetic bearings were interfering with my generator magnet on the same shaft. We are going to re-visit this concept in the future as we are predicting there will be no need for a generator. The Turbine in vacuum is capable of generating electricity via electrostatics. This we also need a metal rotor for.
@@iEnergySupply My idea actually came from another video of yours where you did tests with magnetic levitation bearings, not only from your video, actually I'm doing research on youtube to see this type of stuffs and in fact I found your channel through these searches.
But you are also right, the imbalance comes from magnetic interference ... something would also be needed that insulates the levitation bearings from interference, and in this I am totally ignorant, is there any material or method that insulates-limits magnetic interference ???
@@proges mabe by making the shaft longer and the magnet farter away in the box it will be enought to cancel the interference, ??
How did you ensure the bearings were aligned when the springs were untensioned in the initial (unforced) position?
Is it possible that the air hitting the notch every revolution causes a side force on the axle?
Also have you look into Gerard morin drive ? mabe some of his stuff can help your electrical parts of the problem,, if what he was working a couple year ago is truly working,,it is actually what you need for your turbine,, its the generator and electrical parts of your problem.
I wonder what happened to Gerard Morin. He seems to have disappeared.
Isn't the air causing unwanted motion?
A little bit, my new balancing apparatus is better and the air doesn't affect it. If you can spin it up to high speeds while you balance it it works better.
Where/ how was material removed to resolve dynamic balance? Outside faces of rotor only?
one was balanced after the other.
@@iEnergySupply what a reply... that doesn't answer his question in the slightest. WHERE and HOW was the material removed, to resolve dynamic balance?
your answer was to "when" which was not a question that was asked. this is middle school stuff. read the question BEFORE answering
@@bmxscape did you watch the video?
@@iEnergySupply did you read the question which you attempted to answer?
once you can make or get your hand onto magnetic bering,,its actually not too hard to make,, your thing will work better than spring,, as modern mechanical battery use magnet levitation bering in a vacuum .
we have made them before and plan to return in the future.
Aren't they automatically ballenced when you machine them on the lathe?
Maybe if your lathe and setup are perfect, but this is never so
Also the materials density would have to be perfect even through out
So true and Balanced are 2 separate things.
you can see the plastic frame pieces jumping around, moving instead of the piece you are trying to balance, causing imbalance
Yeah it's my first attempt, I've since made many improvements.
Wo tool we don,t know how much vibration and spectrum was
"i had problems with plastic exploding at 40,000 plus rpm", like no shit it does, if you spin anything unbalanced to 40,000 rpm bad things are gonna happen
Yeah a blast shield is a must at those speeds, I only get this one up to around 10,000k rpm.
Thats amazıng I use thıs perfect
Has anyone tried a circular saw blade in a Tesla turbine?
Would be great if you could cut the exhaust holes just right.

but now im thinking itll have that oscillation and i wont be able to grind it down. im excited to giveit a shot 😜
Thank you! Good idea thinking about the grinding wheels, I've thought about it before but one thing to note with the grinder wheels is they can't take as high rpm as some of the better materials out there. Also they need exhaust holes in the center of the disks. We will be giving more construction details soon, and the best materials to use for the disks. It's actually quite cheap to pay a company out there with a water jet to cut you're disks. I can give cad drawings that you can hand over to them in the future.

the fact researchers like you take the time of day to respond to some kid on the internet is the reason this community exists.
Can you make a moving bicycle with this project 😀😀😀 😎😎😎
That’s great, because there are a lot of lexan rotors that don’t need to retain any particular size or shape being used in industrial applications. 😂😂😂😂😂
Have you seen this in action? We got over a kw with a 3" rotor, made of plastic. Plastic was just for easy prototyping.
@@iEnergySupply My point was that there is no real practical application for this type of balancing. It's an interesting little experiment, but that's all. By the way, it would work a lot better if you didn't suspend the bearings in springs. The springs' result is to make a phase angle impossible to determine, either by vibration equipment or by the shaving off of eccentricity in this method. What that means is that more often than not, you'll be shaving off something other than the heavy side. Try it again mounted in a rigid frame and you'll see. Or more accurately you *won't* see (any movement) but you will be able to shave off the actual heavy side only. It will be much faster and much more accurate.
Actually, that method is described in detail by Nicola Tesla as a requirement for his turbine design. According to the frequency and resonance, you could do static balance, dynamic or both. But I never thought of that size fact.... Would it work better (size wise or less vibration), if you first statically balance it with weights (or cutouts) and after that use this grinding method?@@DavidFerree54 @iEnergySupply
you must balance the wheel ...
In due time.
Hi, do you have a Facebook to share with me or an email?
Yeah, if you look up ienergysupply jeremiah, you'll find me.
p
ha?
Or, you could just use a real balancing machine and have the job done in about 10 minutes. And, you'd actually know what tolerance you achieved. This is both silly and dangerous.
I have since improved the apparatus. Also I had some professionally balanced and the professionals seem to have difficulty achieving a good balance when ran at high speeds. It's important for me to understand all the areas of this research and experimentation is the fastest way I've found to learn.
