Nikola Tesla designed a bladeless turbine in 1910. He Patented a design in the US on 6th of May 1913. in 1916 Tesla describes the Tesla Turbine as his best invention to date.
Ironically this is not as fast as it needs to be to reach optimal efficiency the faster the Tesla turbine spins the more efficient it becomes unfortunately Material Science is still not at a stage where it can achieve its 97% efficiency for that something that's three meters across would have to spin at 50000 RPMs the tip of the turbine would be going nearly mach 20 the disks would simply blow apart we would need to probably experiment with graphene discs pure graphene in its proper lattice can support the weight of an elephant on a surface area approximately the size of a tip of a pencil but making it is incredibly expensive
@@Ultimusvivi Yup. This is why they are only used in large commercial or industrial fashion like water dams n such. I only made that statement as a safety caution from discipline of not putting ones self in harm while working around large machines.
High speed and low torque can easily be converted to low speed and high torque through the use of a TRANSMISSION. Look at a shipboard propulsion system. A steam turbine with low torque and high speed using a pinion gear of only 1 foot in diameter turns a Bull Gear with 20 foot diameter. The mechanical advantage is enough to drive a ship through the water. These guys are on the right track!
Sue, yes but first you have to have something moving at high speed to convert. The base problem is finding a material that can survive the stress at 35k rpm.
@@narwhal9852 I say it is on earth but don't know how to create it / harness it. Just like how all the granite was cut on the pyramids and other ancient sites. I think we are overlooking / overthinking things. Seems 99% of our innovation is slapping a computer on something that is a existing. In a way yes it doesn't exist but only because we haven't figured out how.
In his patents, Tesla specifies utilizing his turbine configured in three ways, as a vacuum pump, turbine, and air compressor, configured together in such a way so the relationship between the three parts function as both the power source and effectively as the transmission, by regulating airflow to the drive member.
I have wondered what would happen if the very outer edges of the discs had tiny magnets and the casing had coils for them to pass by as the turbine passed by at 3000 rpm. It would generate small electric charges and in the millions. Instead of taking the power from the shaft, take it at the outer edge using magnetism.
O super idee cu turbina lui tesla eczact cum ai zis cu magneți și bobinaj din cupru făcut tip generator ar produce curent fără nici o problema, super tare frate💪🤜🤛👍
We'll get a lot of problems with magnets itself (demagnetizing because they would reach Curie point) and vibration of discs caused by interaction between magnets fields and current field in coils. Most possibly turbine will "disassemble" itself from vibrations.
@@teolynx3805 If you offset an electromagnet of the opposite polarity to counter the bucking effect of the gap(s) it would prevent vibration and demagnetizing.
You need magnetic frictionless bearings. Standard style bearings will not work at 10k rpm for long. And you need to reach alot higher rpm for efficiency, right?
Thank You for the great video. Sadly not much information except seeing the high rpm. Sad about the bearing. I would have loved to see more as You would have too. I hope that You did not lose a lot of money on this great experiment. Ignore all those demanding and negative remarks. Keep going Guys. You will achieve what You are trying for. I forgot to ask you, What was the water pressure on the intake? Again Thank You
Don't you know that this beautiful masterpiece won't long last due to its acceleration and speed??? Its ring can be stretched out of that cylinder and can kill you
Automotive turbochargers routinely pull tens of thousands of RPMs under high heat on oil bearings while processing dirty-ish gasoline or diesel exhaust. This is not a significant engineering problem in this day and age, just a bit more complexity to the existing design. A Tesla turbine as oil pump would be more than up to the supply task.
Yes or operating an air conditioner. problem with Tesla (anything) has always been centralized power ideology concerned with industrial size application.
I have wondered this exact same thing. I want to make a hydro-powered turbo for a boat application using the water from the jetpump. How do automotive turbos spin well over 200,000rpm without warping?
@@THEKITPLUG They're low mass, and float on 2 Turbine shaft oil bearings: 2 film thicknesses surround a precision sleeve between the outer bearing and the shaft The oil films dampen minute vibrations.
Laminar flow over the disc is a key importance to the work of the turbine. The more turbulent the flow past the discs, the lower the efficiency of the turbine. Determine the Reynold's number by 3/4 * density * velocity divided by coefficient of velocity. You want a Reynold's number less than 2000 to be considered a Laminar flow.
It's an excellent model, it just needs a more durable bearing setup. Alternatively, you could investigate using something like magnetic bearings (though that would probably require a complete redesign). As someone else suggested, you could take advantage of the fact that you're using vapor as a working fluid and try something like floating bearings, etc.
Also in watching the video, I see clear things now that I had missed before in watching it. I thought there was water flowing in one side and out the other, but now I see that the pipe coming from the other side terminates. But in being wrong, I've learned things, and I have you to thank for that for sticking it out to show me my error.
It is foolish to say 97% efficient. We should speak in terms of practical and achievable numbers. Even the car manufacturers can say their engines are theoretically 90% efficient, and they just doesn't have the material to manufacture and output that efficiency.
I was under the distinct impression that the Tesla turbine was supposed to run on water, not air. It would be self-lubricating. Water pressure is easy to create/harness/obtain. Air pressure takes a lot of energy to create/harness/obtain.
@@jorgefajardo2213 the Tesla patent explicit talks about using steam and air.

I have two small bladeless model air-powered turbines here, one of which has been run safely at shaft speeds of over 25,000 rpm, using sleeve bearings and a simple bevel gearbox to produce a surprising amount of output torque for the size. But as small models, they're not very efficient. They were built in the early 1960's. An experimental prototype bladeless turbine, using an air bearing, was built by the same person, and which ran faster than 200,000 rpm. (The competition judge's tachometer could not read above 200,000 rpm.) The rotor was conical, and less than 5 cm (2” in old money) in diameter, and it sat in a conical cup. But it did no useful work, since it was designed purely to spin as fast as possible without falling apart. No exotic alloys were used. What I'm saying is that rotational speed capabilities are different for different turbines, depending upon the intended use. Jet engine turbines can run faster than 100,000 rpm, for example, while yours were designed to run at much slower speeds. The guys in this video certainly ran their turbine faster than the bearings could withstand, and were risking physical injury there. If the rotor had exploded, it could have shattered the housing and scattered its remains at high velocity. I've seen it happen.
@@RWBHere wise words man really nice to see somebody how knows his stuff, you can actually run the Tesla turbine at any speed whit Any diameter whit high efficiency if you just get the spacing right for the type of vluid, viscosity to get the right cohisive effect en reduce the slip factor to almost zero, you see this slip factor is the efficiency itself as you get rit of it Tue efficiency rises
This is because your turbines are designed to operate direct on shaft to a 2 pole generator and spin at 3600rpm to get 60hz directly out of the generator.
@@JP-hr3xq I appreciate your comment but that’s not an issue because, despite what everyone erroneously claims, Tesla turbines work just fine, get plenty of torque and output power at low RPMs. I’ve got some copy pasta 🍝 of mine that I’ll share with ya here to explain more. Tesla turbines aren’t made efficient by spinning really fast. That’s only for when the disc stack is being used as a centrifugal pump, because ALL centrifugal pumps’ compressors, performance is tip speed dependent. But spinning the turbine fast will produce a centrifugal head that opposes the incoming fluid flow, reducing the pressure gradient across the nozzle, reducing fluid final velocity, reducing mass flow rates through the nozzle and ultimately reducing power out. Furthermore the faster you spin them the faster the fluid you have has to go just to still be moving faster than the discs and still provide torque. Lastly, they work just fine for industrial use and can scale up just fine because the torque on the discs is proportional to the difference in the fluid speed and the disc speed. So the disc tip speed is the important factor here. For any given fluid supply in the nozzle will have a max fluid velocity. So the turbine disc tips will have a max speed set at that fluid speed irrelevant if radius. Now considering that centripetal force is proportional to V^2/R, if you keep the tip speed the same but increase the radius the centripetal forces on the disc for the speeds needed will actually decrease. Despite what MANY have claimed about the Tesla turbine, it does NOT need to be spun fast to work or work efficiently. TesTurs are made efficient when the slip on the discs is reduced and spinning the discs fast does nothing to reduce the slip, only increase the distance the fluid slips on the disc faces, which is by definition “loss”. Listen to what Tesla himself said in the patents of how to make them work. “Owing to a number of causes affecting the performance, it is difficult to frame a precise rule which would be generally applicable, but it may be stated that within certain limits, and other conditions being the same, the torque is directly proportionate to the square of the velocity of the fluid relatively to the runner and to the effective area of the disks and, inversely, to the distance separating them. The machine will, generally, perform its maximum work when the effective speed of the runner is one-half of that of the fluid; but to attain the highest economy, the relative speed or slip, for any given performance, should be as small as possible. This condition may be to any desired degree approximated by increasing the active area of and reducing the space between the disks.” 1) increase the speed of the fluid relative to the disc, (not increase disc speed) 2) increase surface area 3) decrease disc spacing This is how you actually make a TesTur work. Not by spinning it fast. The fluid interactions with the disc that govern efficiency an torque are adhesion and cohesion. Full stop. And spinning fast does nothing to increasing either to increase the turbines isentropic efficiency. This is why everyone who chases rpm with the TesTur just flat out fails. They aren’t even trying to design them properly so of course they won’t work.
Lenz's law is the only pertinent resistance you'd have to worry about once you put the load on it. Rolling resistance would be negligible in its effect. While it may be folly of me to assume as much, I was suspecting they were using city water which has a pretty consistent pressure. And I would love to show you the formulas used to determine the theoretical efficiency of a Tesla turbine, TH-cam isn't math-friendly, but I'll cover them as best as I can in a linear fashion with my next post
Wow, I didn't know that, but that doesn't explain why so many people are home-building replicas, hooking them up to hoses and filming them running with nothing else connected as if they've just made the first working model in history. You could tie a pair of underpants to a shaft, put it in a housing with an angled jet and do that. Btw, I am a student of electronics, I know Tesla was an absolute genius.
Geo K - "At least a rotor disk didn't fracture from the intense centrifugal force" That's what I was thinking was going to happen. That's a pretty large diameter for that RPM...
Thanks for posting this video. It was bereft of explanatory byplay or text, so we have to guess what you were doing, but at least someone knows how to weld aluminum, and there must be a machine shop involved. The gas/steam exit path seems rather small at the turbine housing, and that could be enlarged relatively easily. Bearings are straightforward issue, but the exact contours of the critical areas of the gas/steam path deserve careful study. Good luck with it.
I was thinking as I watched them spinning it up, I hope they spent as much on the shaft bearings as they did for the entire rest of the project, or it's not going to spin very long. Hmmmm.
I think some of you forget that tesla also invented the torque converter, which designed to be attached to this device. If you know both of these, then you'd know that RPM CAN be converted into torque and vise versa. The fluidic drive was also another device which would also use a fluidic valve; both devices seem lost in time.
Tesla pump is good for high viscous fluid, for example maple syrup. You either have to spin up very quickly with air, or spin slowly with maple syrup. It depends on the type of fluid
Imagine thousands of these used to power a big ship, like the titanic. I think it sunk a year before this was made and the discs wouldn't be strong enough and would tear apart
KattieKirksey1875 Sorry, no sale. I always turn off an advertizing video if I have to wait more than a minute into it to find out what they're actually selling. Also, it was no reason for you to post your ad twice. I'm afraid I'm going to have to report one of those posts as spam. Have a nice day

cooked the seals on the bearings............ I guess they did not follow the old school TESLA directions with old school packing.. PLUS, RPM runaway.... too high. PS: WHERE IS THE TORQUE in it.. no work, no go for usefulness.................
Look up Tesla and the Niagara falls. The Tesla Turbine was the first device used in the first major hydroelectric generating plant in the world, This was in 1895. His turbines were connected to 10 massive poly-phase generators for a combined output of 75Mw. (That's 75 million watts, quite a feat for the day) . So, yes, they have done the hard yard, for longer then you've been alive.

I have often wondered what would happen if, instead of making the entire disc of metal, what would happen if part of the disk were made of high tinsel strength cloth or a polymer that had great shape memory, in the highest speed regions. The centrifugal force would force the material to remain extended and if the material had a decent stretch factor with room in the casing to allow for stretch, theoretically, that would enable fantastically higher speeds. As for the bearing failure, that might be overcome with the use of a magnetized shaft and permanent magnets of like polarity as a bushing. A semi-solid disk of graphene weave might offer a better resolve.
Tesla turbine needs VERY high speed to operate at maximum performance. That is the biggest problem for using Tesla turbine. Many people are running Tesla turbine at low RPM and claim its not working. I recommend to those people to drive their car engine at 30 RPM and drive up hill. As I can see, these people are trying right, to put it at high RPM. That is no child play. Best Regards to all
Awesome turbine but I would have been more interested to see a load applied to test the tork of such a turbine spinning it over 8k rpm was bound to do that probably needs the right bearings
@@350pauli I have already built working TesTurs that output plenty of torque and plenty of power even at low RPMs. They just have to be designed correctly. There’s all the proof anyone could need to know this now. 10in diameter TesTur made from cheapo aluminum on room temperature compressed air Dyno’d at 6.22ft-Ibs of torque to the shaft at only 4150rpm and +4250watts between 6,000-12,000 rpm and real 250-2650watt electrical load test runs at 9,000-13,000rpm. The preliminary tests are just to see how much electrical power can be produced with room temp compressed air driving the Tesla turbine. The TesTur nozzles never went over 20psi at the nozzle for the 2650watt electrical load test and not over 40psi at the nozzle for the 4250watt dyno test. This is so a baseline can be acquired for what to expect as the temps are increased to combustion levels. When using elastic gasses the counterintuitive thing most overlook is that the viscosity of gasses goes up with temp. So not only is there an increase in thermodynamic efficiency from increased temps but the TesTur isentropic efficiency also goes up due to the reduced slip from the increased viscosity.
I agree. I have yet to see a demo of one of these actually doing "work". They just spin them up and that's it. Big deal. If it can't do "work" it's just a toy, and if it can they need to demonstrate that.
🙋♂️ the TesTur of ours has been proven more than capable of output real work. 250-2650watt real electrical load tests all on just room temp compressed air. The preliminary tests are just to see how much electrical power can be produced with room temp compressed air driving the Tesla turbine. The TesTur nozzles never went over 20psi at the nozzle for the 2650watt electrical load test and not over 40psi at the nozzle for the 4250watt dyno test. This is so I can get a baseline for what to expect as I increase the temps to combustion levels. When using elastic gasses the counterintuitive thing most overlook is that the viscosity of gasses goes up with temp. So not only do we see an increase in thermodynamic efficiency from increased temps but the TesTur isentropic efficiency also goes up due to the reduced slip from the increased viscosity.
This may be off topic, but someone might find it interesting. Over unity electric generator. By AMA. Segment 1: 1 motor with bar connected to it standing vertically. Circular disc connected to bar that has magnets embedded in it surrounded in high permeability material to focus magnets outward pushing force in an upwards direction from top of disc. Segment 2: Hollowed out cylindrical Bar of material horizontally positioned. Flat hollowed out ring shaped material with openings around its outer top flat edge. Magnets surrounded in high permeability material embedded in these openings. Magnets positioned in openings around ring are in at least 1 of 2 configurations either all N magnetic field pushing out or N,S,N,S all around it. Just depends on whether your going for Piston structure or spinning structure explained below & whether you want it to be DC or AC current. Place these all along the cylindrical bar connected to it solidly, except at far ends of bar. At both ends of bar place ring of material that can be magnetically repelled in specific locations. (magnetically repelled in specific location is in reference to outside of ring area that faces away from center of bar)(Other side of same ring facing in towards center of bar is capable of being magnetically repelled all around) Ring must be connected solidly to bar. points of repulsion on these rings is off set from each other on each end of bar. 3 Hollow ring structures with small square bars protruding from each. Ring structure has all magnetic repulsion on inside of ring shape & can rap around the main bar so that the bar wont be causing friction on things as it moves back and forth or spins. 1st positioned around far left of bar, 2nd position at center of bar (be sure to leave enough room for magnetic structures to be able to move back and forth without hitting it) & 3rd positioned on far right of bar. Tube structure is constructed in two parts that fit together on top of each other length wise over main structure. Tube structure has 3 square openings for the bars that the Ring structures that are connected around the main bar keeping it from causing friction on structure, to slide into. This tube structure is designed with material that does not block magnetic fields. Perhaps some type of transparent material glass or other. At both ends of the tube structure there is a built in circular groove that will house a round disc. The ceiling/floor/left side/& right side of groove has openings for small magnets to be embedded in it, so that the pushing force from magnets is pushing in towards the edge of disc that goes in this spot. There is also 4 openings located on the top, bottom, left & right positions of the open groove. Small magnets are placed in these spots so when round disc is in position these magnetic fields will hit sideways keeping it from generating friction against structure. Far Ends of bar has Cap structure that screws over tube halves holding them together. Cap structure also has 4 points on inside top, bottom, left & right that have openings. These openings have small embedded magnets in them that exert there pushing force outwards (sideways) so it will keep disc in position, generating no friction against structure. Cap is made of material like tube so it does not block magnetic fields. (Note: These magnets in groove and cap structure are only needed for piston design. If Disc is directly connected to main bar so as it spins the bar spins, magnets are not needed here). The disc has ring around it (ring of material goes around outer edge and folds over front side & backside a small distance) that is repelled by magnetic fields so the 12 small magnets will keep it lined up but it will be able to spin without causing friction on structure. The disc has openings on it's flat side that face inside of tube and magnets surrounded in high permeability material are embedded in this disc. The disc has small bar that is connected to it's center that goes all the way to the other end of bar structure through the center of the hollowed out bar and connects to disc on other end. Disc on other end is set up the same but magnets embedded in it are off set in comparison. As first disc spins the magnetic fields will push against specific spot on disc connected directly to bar, pushing bar in other direction, once bar is fully pushed over, further spinning of disc will then align the other sides magnet to push it back. Tube structure also has half moon shaped protrusion on inside and on both halves so when tube is connected they line up to make a full ring shape on inside of tube, these half moon shaped protrusions have at least 1 small round opening on it's side in middle of curve that faces away from center of bar. The opening has a small magnet embedded in it so magnetic force is repelling out sideways away from center of bar. The protruding ring is positioned to line up slightly further in towards center of bar then the ring of magnetically repelled material connected directly to bar. This way when bar moves right or left it is magnetically stopped after a short distance. Copper coil setup: Copper coils are wound in at least 1 of 2 ways. Either coiled in circles next to each other (Like if you wound coils around a cylindrical bar) or laid out in a row as if wire was on flat table going up then bent to go down & back up until it formed a flat rectangle of wire bending up and down and then the entire structure folded around tube. Copper windings are then lined up perpendicular to magnetic fields on outside of tube. Ends of copper coils are connected into separate construct that will allow electrical current to flow somewhere else. Circular construct is built like a stand that goes around the outside of motor segment. Circular construct has flat ring of high permeability (magnetic field shielding) material that has small openings that will allow magnetic fields through specific locations. Top of circular construct has groove to allow the horizontal bar to balance on. Circular construct can also be placed on other end of bar so it is balanced. The motor segment is positioned so the disc connected to the bar that is connected to the motor is lined up so the disc passes under the horizontal bars disc that is at end of horizontal bar. The high permeability material keeps the magnetic fields in disc from hitting into the disc that spins or pushes the horizontal bar until just the right moment when the impact will cause the disc in horizontal bar to spin which will perpetuate the piston motion in the horizontal bar. More horizontal bars of the same design are built and positioned around the motor segment in a circular horizontal fashion all the way around. The bar connected to the motor can be increased in length to desired height (As much as motor can handle) and more of the exact same setup is repeated higher and higher up, maximizing the over unity potential of the construct to ridiculous proportions. :D Current from the horizontal bars is diverted to power the motor as needed and all other current is diverted to power my game console or the world. :) Interesting variation to this design would be to connect the spinning discs on far ends of horizontal bar to main bar that magnets are connected to so the magnets spin instead of getting pistoned back and forth. So long as moving magnetic fields are perpendicular to copper wires it should work. By AMA

What I was trying to say is that you can use the RPM to achieve more torque using a transmission of some kind. It's like a transformer transforming Very high voltage with little amps to something that has medium voltage with medium amps. A gearbox does something similar. It takes the RPM and Torque and manipulates it into something usuable. Sorry if I wasn't clear the first time :D
Exactly. They say in the vid 'immense' rpm. What I'm getting at is there might still be very little horsepower (wattage) because rpm does not equal power.
Good news is the many disks in a Tessa turbine are usually very light, as it'd be impractical to make them heavy. So the what looks to be stainless steel frame probably could take the full force of the turbine shredding apart.
So, it spins fast, unloaded. That's usually the extent of these turbine videos. I would rather see on actually hooked to something and doing actual work. I can spin a PC fan with an air compressor *really* fast, but that accomplishes nothing. Want to impress me, hook it to a generator or something.
+Moonteeth62 If you'd done your "homework" you would have known the uses for it. But I'll endulge you for the sake of it. These devices are and can be used both ways. As a strong air compressor when a motor is applied to it or as a high RPM motor, powered by high pressure steam for example. Unloaded in the videos, yes. It can be used for rapid water removal from a pool for an example. Or even more practical, on a bigger boat, for water removal should there be a big leak. You shouldn't say it wouldn't work loaded. No turbine, not adjusted to the appropriate generator will not work loaded. With big enough dimensions, I'm sure as hell she could produce power.

I see nobody commenting on this but whatever liquid they are pumping into the turbine was not coming out of the exit tube. Tesla's design of this turbine was a hydraulic turbine. Were they pumping air into this turbine ? It could be. A pressurized oil sump system to the bearings could probably get it nearer to 50,000 RPM's
Yes you we're clear. Imagine a wheel with good bearings. You apply little force and it starts spinning and will eventually reach great rpm. Now add a load to the wheel (like a generator) and the little force that got it spinning is no longer enough to keep up the speed.
Why dont youbuild one with your money and add a shit load of gears to it? I'm sure these third world souls could use you money if your to lazy to do it yourself
Jarrod P Remember my boy, Tesla was influenced by ETs and space do not need strength, but speed is what we need, this is what we have with this turbine !!
When developed there were no materials that would withstand 18,000 rpm, but it was at these speeds where best efficiency was gained. However, by WWII materials were available. GE aircraft turbos spun at 18,000 rpm at first, then as development progressed would do 23,000 rpm. The high rpm increased the pump efficiency to 97%, and tesla pumps are used in specific apps still today.
Where did you get this information from? Because at the Edison steam plant tests that Tesla did with his turbine Tesla did the 100hp run on his 9-3/4in diameter turbine at 18,000rpm… so where exactly did you hear he couldn’t spin his turning that fast back then?
A Tesla Turbine can have amazing efficiency, but the speed it has to spin to achieve the efficiency is far beyond what any material we know of can withstand.
I'm still waiting for an useful Tesla turbine application video. All the videos I see are people spinning the Tesla turbine like crazy without doing anything useful with it. Of course it will spin fast if there is no load! It's like I would be watching somebody pedalling on a bicycle suspended in the air.
+miro2424 I'm working on it, i want to build a Tesla gas turbine+generator prototype (driven by gasoline) in the 1 kW range. Hard problem to solve will be temperature, but may be solved by using bypass air from compressor stage, which could reduce heat on the plates while giving away a bit of efficiency. Another problem would be to make it as silent as possible. And then another big big problem would be clogging of the space between the discs. I think all these problems could be solved eventually. I'm still in drawing/calculation phase, proabably will start assembling the first prototype latest in about half a year from now.
the hots gases impinging on the discs are likely to erode them. It also has a relatively high inertia value which is ok for single speed/steady load engines (generators) but lousy for cars.
At the time of Tesla traditional turbine was low efficient and hard to produce, also a lack of material good enough to make reliable and efficient blade turbine, so his design intended to solve cost of production problem, the 95% was only theoreticaly possible, not practicaly prooved with technology of that time, scientificaly its prooved that it may reach 95% and over, but very few attention was given to Tesla turbine in last 100 years. The reason is new tecnological breakthrough in metallurgy solved the original problems, making the tesla invention less interesting, as it would take a lot of time and money to develope his turbine and more money to replace all machines with his new turbine, taking the industrial capacity of mankind in early 20th century, that was hard to achive. The interest to Tesla turbine came back in 1950, when they actually theoretically prooved the potential of Tesla turbine efficiency, however it requires new technology to create a truly working one. So far one one was able to truly create a Tesla turbine that work better than current turbine design. The design of Tesla turbine only look simple, in order to make it work, it must have as many disk as possible, but the distance between disks must be the same as the disk thickness, we cannot just extend the width of turbine adding more layers, coz we would need to extend the width of steam flew on those layers too. So far no one was able to create a tubine with enough disk layers with appropriate accuracy to achive higher efficiency than traditional turbine. So Tesla turbine can work in theory, we just haven't reached the point where we could create one.
Battlecry Eden Never heard this particular perspective on this. Once, I heard Nikola Tesla had developed the turbine especially for applications with high frequency generators he had been experimenting with, where these high rotation rates would've been a good? Not sure.
As skylos stated, you should have it under at least a simulated load. You would never build an engine for a drag car and test it just to see how high you could get it to rev. Very nice work none the less !
+Mollygaga42 After the vortex and and centrifugal forces synchronize the RPM jumps dramatically and the turbine goes relatively quiet. Unfortunately, in this video, it looks like it failed before reaching that point.
You sacrifice speed by adding discs for torque. But torque is based on how much steam you can generate as well - which is essentially infinite. So phase two! More discs! I want to see a locomotive by the time you are finished!
may be you guys need some bearing that couldnt have a friction, floating bearing maybe based on magnet levitation. at least the friction transfered to the air 😁
Personally I have had and seen and used what's called an air bearing. The tolerances are extremely tight but they're really effective for reduced fiction

i WOULD NOT be standing that close to something spinning that fast.
Ironically this is not as fast as it needs to be to reach optimal efficiency the faster the Tesla turbine spins the more efficient it becomes unfortunately Material Science is still not at a stage where it can achieve its 97% efficiency for that something that's three meters across would have to spin at 50000 RPMs the tip of the turbine would be going nearly mach 20 the disks would simply blow apart we would need to probably experiment with graphene discs pure graphene in its proper lattice can support the weight of an elephant on a surface area approximately the size of a tip of a pencil but making it is incredibly expensive

I have wondered what would happen if the very outer edges of the discs had tiny magnets and the casing had coils for them to pass by as the turbine passed by at 3000 rpm. It would generate small electric charges and in the millions. Instead of taking the power from the shaft, take it at the outer edge using magnetism.

:) That's why they count magnetism in "Tesla" ;)
even more . running it with air would cool coils and magnets 🙂
We'll get a lot of problems with magnets itself (demagnetizing because they would reach Curie point) and vibration of discs caused by interaction between magnets fields and current field in coils. Most possibly turbine will "disassemble" itself from vibrations.
@@teolynx3805 If you offset an electromagnet of the opposite polarity to counter the bucking effect of the gap(s) it would prevent vibration and demagnetizing.
You need magnetic frictionless bearings. Standard style bearings will not work at 10k rpm for long. And you need to reach alot higher rpm for efficiency, right?
About 30000 tesla said to be 97% efficient

Automotive turbochargers routinely pull tens of thousands of RPMs under high heat on oil bearings while processing dirty-ish gasoline or diesel exhaust. This is not a significant engineering problem in this day and age, just a bit more complexity to the existing design. A Tesla turbine as oil pump would be more than up to the supply task.

Laminar flow over the disc is a key importance to the work of the turbine. The more turbulent the flow past the discs, the lower the efficiency of the turbine. Determine the Reynold's number by 3/4 * density * velocity divided by coefficient of velocity. You want a Reynold's number less than 2000 to be considered a Laminar flow.
It's an excellent model, it just needs a more durable bearing setup. Alternatively, you could investigate using something like magnetic bearings (though that would probably require a complete redesign). As someone else suggested, you could take advantage of the fact that you're using vapor as a working fluid and try something like floating bearings, etc.

Tesla Turbine is 97% efficient at 35000 RPM. No known material can handle that speed.
That's just a theoretical calculation, because as you said, no known material can handle that speed. So, 97% efficiency maybe, but not yet
It is foolish to say 97% efficient. We should speak in terms of practical and achievable numbers. Even the car manufacturers can say their engines are theoretically 90% efficient, and they just doesn't have the material to manufacture and output that efficiency.
The 35,000 rpm figure is for Tesla's original 6-inch diameter turbine. The most efficient speed depends on the diameter of the turbine.

Specifically a tesla turbine utilizes the expansion of an elastic gas as it spirals through to the center exhaust holes. If one were to make a disc turbine that did not do this, for example just have the air blow through and out the discs it would be called a Thrupp Turbine. As Thrupp first invented the use of viscous adhesion of a fluid, gas or liquid, to a disc but he did not put exhaust holes at the center of the discs and his did not utilize the expansion of the fluid through a spiral path through the turbine disc stack.
Ok, where's the video that shows the dis-assembly and damage? Now THAT would be cool......

@BIR_jass please
This turbine was running at 8000 rpm even over. In our lab, we never run the reaction steam turbines over 4000 rpm.
I have two small bladeless model air-powered turbines here, one of which has been run safely at shaft speeds of over 25,000 rpm, using sleeve bearings and a simple bevel gearbox to produce a surprising amount of output torque for the size. But as small models, they're not very efficient. They were built in the early 1960's.
An experimental prototype bladeless turbine, using an air bearing, was built by the same person, and which ran faster than 200,000 rpm. (The competition judge's tachometer could not read above 200,000 rpm.) The rotor was conical, and less than 5 cm (2” in old money) in diameter, and it sat in a conical cup. But it did no useful work, since it was designed purely to spin as fast as possible without falling apart. No exotic alloys were used.
What I'm saying is that rotational speed capabilities are different for different turbines, depending upon the intended use. Jet engine turbines can run faster than 100,000 rpm, for example, while yours were designed to run at much slower speeds.
The guys in this video certainly ran their turbine faster than the bearings could withstand, and were risking physical injury there. If the rotor had exploded, it could have shattered the housing and scattered its remains at high velocity. I've seen it happen.
@@RWBHere wise words man really nice to see somebody how knows his stuff, you can actually run the Tesla turbine at any speed whit Any diameter whit high efficiency if you just get the spacing right for the type of vluid, viscosity to get the right cohisive effect en reduce the slip factor to almost zero, you see this slip factor is the efficiency itself as you get rit of it Tue efficiency rises
This is because your turbines are designed to operate direct on shaft to a 2 pole generator and spin at 3600rpm to get 60hz directly out of the generator.

That and they're easy to stall. You do need to know what you're doing with them, but they're quite effective devices.
@@JP-hr3xq I appreciate your comment but that’s not an issue because, despite what everyone erroneously claims, Tesla turbines work just fine, get plenty of torque and output power at low RPMs. I’ve got some copy pasta 🍝 of mine that I’ll share with ya here to explain more. Tesla turbines aren’t made efficient by spinning really fast. That’s only for when the disc stack is being used as a centrifugal pump, because ALL centrifugal pumps’ compressors, performance is tip speed dependent. But spinning the turbine fast will produce a centrifugal head that opposes the incoming fluid flow, reducing the pressure gradient across the nozzle, reducing fluid final velocity, reducing mass flow rates through the nozzle and ultimately reducing power out.
Furthermore the faster you spin them the faster the fluid you have has to go just to still be moving faster than the discs and still provide torque. Lastly, they work just fine for industrial use and can scale up just fine because the torque on the discs is proportional to the difference in the fluid speed and the disc speed. So the disc tip speed is the important factor here. For any given fluid supply in the nozzle will have a max fluid velocity. So the turbine disc tips will have a max speed set at that fluid speed irrelevant if radius. Now considering that centripetal force is proportional to V^2/R, if you keep the tip speed the same but increase the radius the centripetal forces on the disc for the speeds needed will actually decrease.
Despite what MANY have claimed about the Tesla turbine, it does NOT need to be spun fast to work or work efficiently. TesTurs are made efficient when the slip on the discs is reduced and spinning the discs fast does nothing to reduce the slip, only increase the distance the fluid slips on the disc faces, which is by definition “loss”. Listen to what Tesla himself said in the patents of how to make them work. “Owing to a number of causes affecting the performance, it is difficult to frame a precise rule which would be generally applicable, but it may be stated that within certain limits, and other conditions being the same, the torque is directly proportionate to the square of the velocity of the fluid relatively to the runner and to the effective area of the disks and, inversely, to the distance separating them. The machine will, generally, perform its maximum work when the effective speed of the runner is one-half of that of the fluid; but to attain the highest economy, the relative speed or slip, for any given performance, should be as small as possible. This condition may be to any desired degree approximated by increasing the active area of and reducing the space between the disks.” 1) increase the speed of the fluid relative to the disc, (not increase disc speed) 2) increase surface area 3) decrease disc spacing This is how you actually make a TesTur work. Not by spinning it fast. The fluid interactions with the disc that govern efficiency an torque are adhesion and cohesion. Full stop. And spinning fast does nothing to increasing either to increase the turbines isentropic efficiency. This is why everyone who chases rpm with the TesTur just flat out fails. They aren’t even trying to design them properly so of course they won’t work.
Lenz's law is the only pertinent resistance you'd have to worry about once you put the load on it. Rolling resistance would be negligible in its effect. While it may be folly of me to assume as much, I was suspecting they were using city water which has a pretty consistent pressure. And I would love to show you the formulas used to determine the theoretical efficiency of a Tesla turbine, TH-cam isn't math-friendly, but I'll cover them as best as I can in a linear fashion with my next post
2:04 the frog hopping at the end is cute
Wow, I didn't know that, but that doesn't explain why so many people are home-building replicas, hooking them up to hoses and filming them running with nothing else connected as if they've just made the first working model in history.
You could tie a pair of underpants to a shaft, put it in a housing with an angled jet and do that.
Btw, I am a student of electronics, I know Tesla was an absolute genius.
Geo K - "At least a rotor disk didn't fracture from the intense centrifugal force" That's what I was thinking was going to happen. That's a pretty large diameter for that RPM...
Yeah, I really don't want to get near that thing..
I was hoping he'd still have his hand intact after it passed 7000 rpm. Very fortunate the bearing failure wasn't a catastrophic one.
Thanks for posting this video. It was bereft of explanatory byplay or text, so we have to guess what you were doing, but at least someone knows how to weld aluminum, and there must be a machine shop involved. The gas/steam exit path seems rather small at the turbine housing, and that could be enlarged relatively easily. Bearings are straightforward issue, but the exact contours of the critical areas of the gas/steam path deserve careful study. Good luck with it.

Useful bearing test!
Should be titled how to break a tesla turbine by overloading the rpm
I was thinking as I watched them spinning it up, I hope they spent as much on the shaft bearings as they did for the entire rest of the project, or it's not going to spin very long. Hmmmm.
I think some of you forget that tesla also invented the torque converter, which designed to be attached to this device. If you know both of these, then you'd know that RPM CAN be converted into torque and vise versa. The fluidic drive was also another device which would also use a fluidic valve; both devices seem lost in time.
The thing with knowLedge is that if nobody remembers it, it doesn’t exist anymore.
Tesla pump is good for high viscous fluid, for example maple syrup. You either have to spin up very quickly with air, or spin slowly with maple syrup. It depends on the type of fluid
Imagine thousands of these used to power a big ship, like the titanic.

wrong
I have often wondered what would happen if, instead of making the entire disc of metal, what would happen if part of the disk were made of high tinsel strength cloth or a polymer that had great shape memory, in the highest speed regions. The centrifugal force would force the material to remain extended and if the material had a decent stretch factor with room in the casing to allow for stretch, theoretically, that would enable fantastically higher speeds. As for the bearing failure, that might be overcome with the use of a magnetized shaft and permanent magnets of like polarity as a bushing. A semi-solid disk of graphene weave might offer a better resolve.

The preliminary tests are just to see how much electrical power can be produced with room temp compressed air driving the Tesla turbine.
The TesTur nozzles never went over 20psi at the nozzle for the 2650watt electrical load test and not over 40psi at the nozzle for the 4250watt dyno test.
This is so a baseline can be acquired for what to expect as the temps are increased to combustion levels. When using elastic gasses the counterintuitive thing most overlook is that the viscosity of gasses goes up with temp.
So not only is there an increase in thermodynamic efficiency from increased temps but the TesTur isentropic efficiency also goes up due to the reduced slip from the increased viscosity.
I agree. I have yet to see a demo of one of these actually doing "work". They just spin them up and that's it. Big deal. If it can't do "work" it's just a toy, and if it can they need to demonstrate that.

The ceiling/floor/left side/& right side of groove has openings for small magnets to be embedded in it, so that the pushing force from magnets is pushing in towards the edge of disc that goes in this spot. There is also 4 openings located on the top, bottom, left & right positions of the open groove. Small magnets are placed in these spots so when round disc is in position these magnetic fields will hit sideways keeping it from generating friction against structure.
Far Ends of bar has Cap structure that screws over tube halves holding them together. Cap structure also has 4 points on inside top, bottom, left & right that have openings. These openings have small embedded magnets in them that exert there pushing force outwards (sideways) so it will keep disc in position, generating no friction against structure. Cap is made of material like tube so it does not block magnetic fields. (Note: These magnets in groove and cap structure are only needed for piston design. If Disc is directly connected to main bar so as it spins the bar spins, magnets are not needed here).
The disc has ring around it (ring of material goes around outer edge and folds over front side & backside a small distance) that is repelled by magnetic fields so the 12 small magnets will keep it lined up but it will be able to spin without causing friction on structure. The disc has openings on it's flat side that face inside of tube and magnets surrounded in high permeability material are embedded in this disc.
The disc has small bar that is connected to it's center that goes all the way to the other end of bar structure through the center of the hollowed out bar and connects to disc on other end. Disc on other end is set up the same but magnets embedded in it are off set in comparison. As first disc spins the magnetic fields will push against specific spot on disc connected directly to bar, pushing bar in other direction, once bar is fully pushed over, further spinning of disc will then align the other sides magnet to push it back.
Tube structure also has half moon shaped protrusion on inside and on both halves so when tube is connected they line up to make a full ring shape on inside of tube, these half moon shaped protrusions have at least 1 small round opening on it's side in middle of curve that faces away from center of bar. The opening has a small magnet embedded in it so magnetic force is repelling out sideways away from center of bar. The protruding ring is positioned to line up slightly further in towards center of bar then the ring of magnetically repelled material connected directly to bar. This way when bar moves right or left it is magnetically stopped after a short distance.
Copper coil setup: Copper coils are wound in at least 1 of 2 ways. Either coiled in circles next to each other (Like if you wound coils around a cylindrical bar) or laid out in a row as if wire was on flat table going up then bent to go down & back up until it formed a flat rectangle of wire bending up and down and then the entire structure folded around tube. Copper windings are then lined up perpendicular to magnetic fields on outside of tube. Ends of copper coils are connected into separate construct that will allow electrical current to flow somewhere else.
Circular construct is built like a stand that goes around the outside of motor segment. Circular construct has flat ring of high permeability (magnetic field shielding) material that has small openings that will allow magnetic fields through specific locations. Top of circular construct has groove to allow the horizontal bar to balance on. Circular construct can also be placed on other end of bar so it is balanced. The motor segment is positioned so the disc connected to the bar that is connected to the motor is lined up so the disc passes under the horizontal bars disc that is at end of horizontal bar. The high permeability material keeps the magnetic fields in disc from hitting into the disc that spins or pushes the horizontal bar until just the right moment when the impact will cause the disc in horizontal bar to spin which will perpetuate the piston motion in the horizontal bar. More horizontal bars of the same design are built and positioned around the motor segment in a circular horizontal fashion all the way around. The bar connected to the motor can be increased in length to desired height (As much as motor can handle) and more of the exact same setup is repeated higher and higher up, maximizing the over unity potential of the construct to ridiculous proportions. :D Current from the horizontal bars is diverted to power the motor as needed and all other current is diverted to power my game console or the world. :) Interesting variation to this design would be to connect the spinning discs on far ends of horizontal bar to main bar that magnets are connected to so the magnets spin instead of getting pistoned back and forth. So long as moving magnetic fields are perpendicular to copper wires it should work. By AMA

Cheia pentru ca un generator electric să funcționeze peste unitate este avantajul mecanic. În acest caz, avantajul mecanic este obținut prin obținerea motorului electric care se rotește pentru a putea învârti o cantitate de discuri verticale separate care sunt conectate la dispozitive care generează curent electric în timp ce se rotește pentru a genera mai mult curent decât motorul electric trebuie să se rotească. Una dintre modalitățile de a realiza acest lucru fără a încălca legile termodinamicii este exploatarea efectelor câmpului magnetic. Pentru a face acest lucru, atașați un disc poziționat orizontal la o bară pe care motorul o învârte. Apoi plasați magneți pe partea de sus a discului orizontal în care motorul electric se învârte astfel încât, în timp ce discul se rotește, câmpurile magnetice se împing în sus pe marginea discurilor verticale în care se lovesc, forțându-le. să se rotească, generând astfel curent electric. Pentru ca câmpurile magnetice să lovească doar una dintre marginile discurilor poziționate vertical, trebuie doar să puneți un material sub discul vertical care împiedică câmpul magnetic să împingă discul până când ajunge la acel loc deschis unde câmpul magnetic poate lovi. sus de marginea discului vertical, împingându-l într-o rotire. În acest fel, câmpurile magnetice vor fi forțate să facă o muncă pe care motorul electric nu o va face. Acesta este modul în care este posibil să se realizeze un generator Over Unity Electric.

Well, I do know tesla generated quite a bit of power using his tesla turbine on the Niagra Falls. One of the first hydroelectric dams, supposedly. I think it was turned into a museum, unfortunately. It's called Adam's Power Station (or Power House No. 3)
what is the application for this turbine?
Fart fan for a Wal-Mart bathroom.
So, I am here after 10 years.
I am after 11 year
How do you guys know how many years you’re returning after? I always see these comments and wonder if it’s just a joke or somehow you can know

R.I.P. brave little bearing :-D
the sound sounds like its gonna blow!
What I was trying to say is that you can use the RPM to achieve more torque using a transmission of some kind. It's like a transformer transforming Very high voltage with little amps to something that has medium voltage with medium amps.
A gearbox does something similar. It takes the RPM and Torque and manipulates it into something usuable. Sorry if I wasn't clear the first time :D
Lost a bearing huh???
What disc material did you use that would not expand?
Exactly. They say in the vid 'immense' rpm. What I'm getting at is there might still be very little horsepower (wattage) because rpm does not equal power.
Well it has power from the velocity. If you rotate a weighted flywheel then it has power.
those people obviously not aware, how dangerous that can be when it rips aparte!
Good news is the many disks in a Tessa turbine are usually very light, as it'd be impractical to make them heavy. So the what looks to be stainless steel frame probably could take the full force of the turbine shredding apart.
This frame probably will not help much, but my english is not sufficient to explain.
when a paper can cut your skin, imagine a fast disk spinning 6k rpm, it will cut the steel like its nothing.
And aparte has it ripte! Free energe! Illuminte confirmde!
Ali A no
So, it spins fast, unloaded. That's usually the extent of these turbine videos. I would rather see on actually hooked to something and doing actual work. I can spin a PC fan with an air compressor *really* fast, but that accomplishes nothing. Want to impress me, hook it to a generator or something.
Go do your homework on these devices, man.
dzemohendrix
Homework is done. Show me a real world use of one of these and I'll stand corrected.
+Moonteeth62 If you'd done your "homework" you would have known the uses for it. But I'll endulge you for the sake of it. These devices are and can be used both ways. As a strong air compressor when a motor is applied to it or as a high RPM motor, powered by high pressure steam for example. Unloaded in the videos, yes. It can be used for rapid water removal from a pool for an example. Or even more practical, on a bigger boat, for water removal should there be a big leak. You shouldn't say it wouldn't work loaded. No turbine, not adjusted to the appropriate generator will not work loaded. With big enough dimensions, I'm sure as hell she could produce power.
Thanks for nothing. I know what *you* think they are good for. Give me a link to a company actually using them, or a link showing an actual REAL WORLD USE.
+Moonteeth62 Good God, you're really this lazy and saucy? Fine.
The high RPM is scaring me even though I'm just watching. It could explode and kill the camera guy and the man holding it
Why does everyone seem to sleep on Tesla’s improved turbine patents?
Tesla Turbine Patent List by Nikola Tesla
US Patent 1,061,206 & GB patent 24,001: the original Tesla disc turbine patent from 1911.
Then almost all Tesla’s improved turbine patents, except the Tesla valve patent, were patented in 1921, the valve was done in 1919.
Patent GB 186,082: improved disc stack design for more torque
Patent GB 186,093: combustion + steam turbine with built in exhaust heat recovery boiler.
GB 186,084: combustion + steam turbine superheater and concentric/coaxial multifluid nozzle that the steam draws a vacuum on the exhaust of the combustion mixing them as they enter the turbine.
GB 175,544: hybrid Tesla Disc + Parson’s reaction turbine for utilizing the Reheat Factor of the energy lost to shearing in the fluid between the discs
GB 186,799: process and apparatus for balancing rotating machinery for quality at-speed dynamic balancing.
US 1,655,114: aerial apparatus patent with improved turbine nozzle design
US 1,329,559: Tesla valve for pulsed combustion Tesla turbine.
GB 179,043: High Vacua Pump
You ar lucky it didnt blow at 10kHz! Should be used at optimum rpm based on the rpm/torque/propellant uptake curve.
Comment at the end was clear "Ouch, ouch" lol
Seems to have blown a shaft seal, indicating to much back pressure in the exhaust. Nice machine though!
and things like pelton turbines have upp to 80% efficiency and a lot of torque if done propperly.
I see nobody commenting on this but whatever liquid they are pumping into the turbine was not coming out of the exit tube. Tesla's design of this turbine was a hydraulic turbine. Were they pumping air into this turbine ? It could be. A pressurized oil sump system to the bearings could probably get it nearer to 50,000 RPM's
Yes you we're clear. Imagine a wheel with good bearings. You apply little force and it starts spinning and will eventually reach great rpm. Now add a load to the wheel (like a generator) and the little force that got it spinning is no longer enough to keep up the speed.
Then you add a flywheel and give it more steam and you're right back to making power
@@hughjass1835 We haven't invented a material strong enough yet.
how many power??
+A Verdade TV Several.
A Verdade TV much*
Many power. All the best power. This I can tell you.
excellent work mad lads!
Great vid.
OK it spins really fast with no load. Lets se it drive a generator and create some AMPS!!
Why dont youbuild one with your money and add a shit load of gears to it? I'm sure these third world souls could use you money if your to lazy to do it yourself
@@stephencrum530 Why don't you build it?
@@stephencrum530 yeah... I do not think they built it.... all for show. and clicks... notice the tally.. someone made $$$$.
Tesla Turbines are only efficient in high RPM.
th-cam.com/video/ioOivnmlRUI/w-d-xo.html
well if you have so much rpm, you can convert it torque by having a correct gear train ryt?
You can trade-off rpm & torque, but the ower is the same.
Steve Alexander power
as soon as a load is introduced the rpm is gone....
nailed it!
Would it be spinning that fast if you put on a few generators?, how much torque does it have?
Scared the frog at the 2' mark.
RPM means nothing without Torque
SOKO MAN This is why you don't see tesla turbines with real loads on them, and forget load change
Jarrod P Remember my boy, Tesla was influenced by ETs and space do not need strength, but speed is what we need, this is what we have with this turbine !!
Show us a tesla turbine with a real load or shut up about it
Jarrod P Boy first improve his words, second, I'm not here to stay teaching concepts that are written in Tesla books, if you want to know read ...
Can you try that in English so we'll all know what you're saying?
When developed there were no materials that would withstand 18,000
rpm, but it was at these speeds where best efficiency was gained.
However, by WWII materials were available. GE aircraft turbos spun
at 18,000 rpm at first, then as development progressed would do 23,000
rpm. The high rpm increased the pump efficiency to 97%, and tesla pumps
are used in specific apps still today.
Where did you get this information from? Because at the Edison steam plant tests that Tesla did with his turbine Tesla did the 100hp run on his 9-3/4in diameter turbine at 18,000rpm… so where exactly did you hear he couldn’t spin his turning that fast back then?
I admire the teams' effort....Guess it needs a governor.
A Tesla Turbine can have amazing efficiency, but the speed it has to spin to achieve the efficiency is far beyond what any material we know of can withstand.
I'm still waiting for an useful Tesla turbine application video. All the videos I see are people spinning the Tesla turbine like crazy without doing anything useful with it. Of course it will spin fast if there is no load! It's like I would be watching somebody pedalling on a bicycle suspended in the air.
+miro2424 I'm working on it, i want to build a Tesla gas turbine+generator prototype (driven by gasoline) in the 1 kW range. Hard problem to solve will be temperature, but may be solved by using bypass air from compressor stage, which could reduce heat on the plates while giving away a bit of efficiency. Another problem would be to make it as silent as possible. And then another big big problem would be clogging of the space between the discs. I think all these problems could be solved eventually. I'm still in drawing/calculation phase, proabably will start assembling the first prototype latest in about half a year from now.
can you ues it as a turbo in a car
the hots gases impinging on the discs are likely to erode them. It also has a relatively high inertia value which is ok for single speed/steady load engines (generators) but lousy for cars.
Alan Brown Yeah i know turbines are not for cars, because of the fast change of power/angular speed needed.
So uhhhh.... do you happen to have any videos of people pedaling bicycles suspended in air, because I need to watch that.
At the time of Tesla traditional turbine was low efficient and hard to produce, also a lack of material good enough to make reliable and efficient blade turbine, so his design intended to solve cost of production problem, the 95% was only theoreticaly possible, not practicaly prooved with technology of that time, scientificaly its prooved that it may reach 95% and over, but very few attention was given to Tesla turbine in last 100 years. The reason is new tecnological breakthrough in metallurgy solved the original problems, making the tesla invention less interesting, as it would take a lot of time and money to develope his turbine and more money to replace all machines with his new turbine, taking the industrial capacity of mankind in early 20th century, that was hard to achive. The interest to Tesla turbine came back in 1950, when they actually theoretically prooved the potential of Tesla turbine efficiency, however it requires new technology to create a truly working one. So far one one was able to truly create a Tesla turbine that work better than current turbine design. The design of Tesla turbine only look simple, in order to make it work, it must have as many disk as possible, but the distance between disks must be the same as the disk thickness, we cannot just extend the width of turbine adding more layers, coz we would need to extend the width of steam flew on those layers too. So far no one was able to create a tubine with enough disk layers with appropriate accuracy to achive higher efficiency than traditional turbine. So Tesla turbine can work in theory, we just haven't reached the point where we could create one.
Battlecry Eden
Never heard this particular perspective on this. Once, I heard Nikola Tesla had developed the turbine especially for applications with high frequency generators he had been experimenting with, where these high rotation rates would've been a good?
Not sure.
yak55x is right. Rpm and torque matter. High rpm without torgue is like static electricity that has extremely high voltage but no amps (no energy).
As skylos stated, you should have it under at least a simulated load. You would never build an engine for a drag car and test it just to see how high you could get it to rev. Very nice work none the less !
Sounds like Formula 1 engine!
Formula-1 engine ~18.000 rpm
18.000 rpm !!!
Fools , Burn and damage beyond repair .
i got here from...dam i can't remember how i got here!
Did you use steam in this test?
Would it work with low pressure steam?
Steam temperature at 200 degrees Celcius
Thanks
That was insane
Burned that bearing!😆😂🤣
Discs. They expended
It won't pass the noise pollution laws I bet
+Mollygaga42 After the vortex and and centrifugal forces synchronize the RPM jumps dramatically and the turbine goes relatively quiet. Unfortunately, in this video, it looks like it failed before reaching that point.
You sacrifice speed by adding discs for torque. But torque is based on how much steam you can generate as well - which is essentially infinite.
So phase two! More discs! I want to see a locomotive by the time you are finished!
may be you guys need some bearing that couldnt have a friction, floating bearing maybe based on magnet levitation. at least the friction transfered to the air 😁
Foil bearings
@@JoshStLouis314 wow excellent, I can't believe it does exist. I commented just what came over my head, thank you for your information.
Personally I have had and seen and used what's called an air bearing. The tolerances are extremely tight but they're really effective for reduced fiction
