I was part of team that built one of these for an Airforce design competition in college. We could reliably get ~94% efficiency with a closed loop superheated steam system harvesting exhaust heat from a small jet engine and got just below 96% efficiency in some ideal test cases. The main limiting factors were that the discs had to be designed to stretch uniformly without distorting at ~40k RPM and that the gaps between the disks had to be designed for an incredibly specific set of operating parameters (steam temp, pressure, velocity, etc.). The smallest variations, or while waiting for it to spin up, and we wouldn't even get close to those efficiencies. A lot of the initial designs weren't efficient enough to reach the right parameters at all.
Oh boy this warrants so many follow-up questions: - Dual outlet or single? - How many discs were used per outlet? - What geometries were used in the outlet? - What diameter went with that RPM? - What was the measured torque output? - Was (or how was) the design compounded? - What materials were used for the discs that had those properties? - Stated efficiency is presumed mechanical, how'd you calculate that efficiency? Was it measured output vs measured losses after the outlet? - What was the name of the competition? Who did you represent or were associated with? I want to find it online or know what I'd need to file a Freedom of Information request with the government because having access to those results would be a game changer for anyone seeking investment in the technology. I'm not looking to call you a liar but you did just say you'd achieved well over twice anyone else's stated efficiency numbers. While I can imagine what you're saying could be true it's still well beyond what anyone has actually demonstrated. So "extraordinary claims = extraordinary evidence" still applies here. Nothing personal! :)
@@Cheebzsta Honestly, it was years ago and I don't remember most of the details but I'll give you what I got. -It used an exhaust manifold with a single exhaust port going into the turbine. The port was also optimized for laminar flow over the disks. The turbine had dual axial exhausts which recombined in a baffle at the manifold's intake. -Around ~15 disks, can't remember exactly. -Turbine exhaust was a circular cut around the axle, broken up by three supports with rounded chamfers. The disks mimicked that but were individually keyed to give the ports a slight offset. The offset actually eked out a bit more (read as "miniscule") efficiency in testing, likely due to artificial radial extension of the fluids path toward the axle. -Around ~10in diameter disks. -Not sure exactly how this design came about except our professor was interested in a practical execution of the turbine and it fit the competition requirements. -The disks were made of a pre-stressed stainless steel alloy. They were individually laser cut then tested at expected RPMs for any unexpected deformations. The vast majority of all disks didn't meet our specs and got tossed out. I think we could only use about 1 in 20 disks by the end of it. -It was primarily a mechanical efficiency and as soon as you throw an alternator on there it's a completely different story. It was measured relative to the steady-state properties of the steam at turbine intake vs turbine exhaust and the kinetic energy of the disks and axle. We measured efficiencies throughout the entire system but that one was the main focus. The most inefficient part of the system was just heating the steam with the jet exhaust without impacting its thrust too much. Surprisingly difficult to do. There was a fair amount of doctoral research on tesla turbines that we used as the basis of our design and which achieved similar efficiencies but it was all at similar or smaller scales. For the amount of effort there aren't really any practical applications for a turbine like this. -I can't remember the name but it's an annual competition (different goals each year) based out of Wright-Patterson AFB in Dayton, Ohio. This one was in 2014 and we were representing the University of Michigan Aerospace Engineering department. It was a shockingly informal process so I'm not sure how much info you could find but if you do look into it and find anything let me know. I'd love to revisit it all.

No it does not, they should have performed actual experiments to back up what they're saying instead of cartoons. Cartoon videos, like NASA, does not prove anything. Shill TH-camr exposed.
I want to add it here so it is visible. But there is actually a way to make the Turbine 10x smaller, but using the "Super Critical Carbon Dioxide." It is a real thing that they can make regular turbine 10x smaller. Another thing that people don't mention. There are 3 inventions on the same shaft: 1. Tesla turbine (takes steam and spins it) 2. Tesla pump (Propels moleculs from the center outwards, creating a vacuum) Both amplify one-another. 3. Air-bearing on both sides. The vacuum-pumps on both ends give more power to the Tesla turbine in between them, and also create a suction for the air-bearings. There are videos of people literally FREEZING steam using the Turbine and Pump in combination. By having the math on all of these right, you can achieve perhaps 99% efficiency. By using the Super Critical Carbon Dioxide, you can down-size it 10x.
You can have a look at the video by a man way more knowledgeable than most men or women out there, on this issue: "A Better way to Make Electricity WITH CO2"
I was a new graduate electrical engineer at Allis-Chalmers Corp. at the research division in West Allis, WI in 1961. At that time, A-C owned the Tesla turbine patent, and I worked beside a fellow mechanical engineer who had been assigned the task of running tests on a compressed air driven Tesla turbine. To load the turbine, a war surplus B-29 engine turbocharger [A-C had made these during WWII, and a few were still lying around] was shaft driven by the test Tesla turbine. A-C was one of the USA manufacturers of steam turbines at that time, and therefore the performance of the Tesla turbine was of interest. After the tests, a full report was written, but is probably lost today, as A-C went out of business in 1986. I am happy to see that others have pursued testing of the Tesla turbine, and have added to the knowledge base. As an interesting side note, Nicola Tesla himself was hired by A-C as an engineering consultant in the early 20th century as revealed in a report on file that my fellow engineer found in the A-C archive. As is well known, Tesla was rather eccentric in his habits. He could not stand to stay overnight in West Allis for some reason, spending his nights out in suburban Waukesha, and commuting by electric rail each workday to the West Allis works. That report too is probably lost.

Thank you Lesics for featuring my "garage project" Here are some info about the "why did you do it, dude?" topic: It was just a proof of concept prototype, which was built to show some people that it works efficiently and safely with compressed air. It was completely home made, that is why it is so robust and crude. I had to be sure that it does not fail, despite being built from cheap brass. Also it had to be self adjusting because I had no way of machining and assembling it with micron precision. I did not have the tools and means to balance the rotor, so it had to be as close to perfect "out of the box" as it was possible. The ceramic ball bearing has a high tolerance which I had to take into account too. I used a 3D printed replaceable nozzle insert, which is easy to adjust to the actual application and parameters. Not to mention how much easier it made the manufacturing. 36000 rpm means about 95 m/s blade edge speed at 1 bar pressure with no load... the theoretical maximum is about 80% of sound speed (without some special nozzle and disk geometry), which is 270 m/s, so I achieved 35% of the possible RPM. With better design and this turbine size the theoretical speed is 100 000 RPM and about 600 watt output with 2.5 bar dry air pressure. This crude prototype run with roughly 45% efficiency at 2 bar pressure (280 watt measured electric power on the brushless motor contacts) I made a 2.0 advanced design for the real application, but that requires expensive machining equipment and special materials (I pushed it to the limit) This one is simple and uses some very basic geometry for easy build. Technical stuff: Disc diameter 50 mm Disc thickness: 0.1 mm Gap: 0.2 mm 3D printed PLA intake nozzle with multipoint output 5 stabilizer pins at the edges, riveted with gap spacers. 4 mm diameter steel axes Ceramic ball bearing Exhaust on both axes directions Brushless motor used as generator with 3 phased output (Maxon ECX-19 high speed motor with ceramic ball bearing) Power output 280 watt at full load. Loaded RPM 18000 RPM

Except he would still be limited today. It's impossible with materials on this planet to make a disc 3m and have it spin at 50,000 RPM without mechanical failure. His design works, it just isn't as efficient as other designs. That's all. Still a cool piece of machinery and still shows his genius.
Tesla was a genius! Not because his inventions were something that no one could make, but exactly because they were very easy to make if you knew which scientific principal i can be applied to which part of an invention. I think that's what makes him a genius.

Nowadays the blades could be made out of titanium which is used in jet engines and turbines which can hold a great deal of heat without distortion and coming apart and allows you to push the boundaries and hold together have a good day
Its wild knowing he sometimes had trouble distinguishing reality from the thoughts in his own head. He was basically a genius who was hallucinating in his everyday life
Not wild at all, he was just a bit weird. He had a tendency to mix religious zealotry with engineering on occasion in ways that just made him sound like a lunatic. The truth is that he was a decent engineer, perhaps even gifted. But not a genius. If Galileo Ferraris had Westinghouse's ear before Tesla then he would be a nobody today. Westinghouse made Tesla, in return Tesla turned around after his death and promptly erased Westinhouse's entire contribution to the electrification effort all while heaping the glory on himself - it's actually pretty tragic. Basically everything positive that popular media says about Tesla is down to other people, mainly Westinghouse and Ferraris.
I think he was untethered from what we call "reality". But if we're being honest, our "reality" is very much just a limiting view of the universe in which we try to contextualise EVERYTHING, so that it makes sense from our very limited perspective. I think Tesla was ego-less and therefore able to see limitless realities that he was comfortable knowing he couldn't comprehend.
Finally someone fully explained why we don't use Tesla turbines in powerhouses. I work on steam turbines in the powerhouses during shutdowns. Most of the engineers I have talked with didn't even know what a Tesla turbine was, let alone why we didn't use them.

This actually helped me figure out pressed fuse glass. You can make glass really thin by pressing it between two kiln shelves, but the thinner it gets, the more it pulls on the kiln shelves, and the more it picks up kiln wash/kiln paper (intended to keep glass from just gluing to the kiln shelves. 3/16" or 4.5 mm can be pressed without destroying the kiln wash coating. 2.5mm cannot. Glass does have a surface tension and "wants" to be about 6 or 7mm thick.
Maybe float your glass on a molten metal? I work glass mostly on a propane/oxygen torch, have tried a little fusing here and there. At some point I saw some videos or toured an old factory (memory is faulty). I think they used lead or tin .
Elon Musk might be able to help you. He knows a lot about glass thickness. He even demonstrated this on a truck named after our man Tesla. What a coincidence!
This turbine has much lower efficiency than any modern turbines. The problem was that at that time there were no technology to produce the blade turbines
@@natteft6593 Oh really? The guys at iEnergySupply beg to differ. What this vid doesn’t say is Tesla said that pulling a vacuum on the exhaust increases efficiency by 50-100%!

TESLA : "It seems that I have always been ahead of my time. I had to wait nineteen years before Niagara was harnessed by my system, fifteen years before the basic inventions for wireless which I gave to the world in 1893 were applied universally." we have to wait more for Tesla Turbine because we dont have strong enough material this monster :)
He created something so powerful and effective that it was too much for the materials he was using. Nikola Tesla may have had OCD, but he was the Chad of engineering.
I am reminded of the movie “Iron Man 2” where Howard Stark designs the mega-molecule but he just doesn’t have the technology to make it himself so he leaves it up to Tony to complete.
To be fair, that can be said about many things. "If only i could build a material stronger than any other known material, my invention would work". Right?
That’s the same problem as now. We can make the small scale ones work with modern materials, but we still can’t use them for their intended Purpose of powering homes and cities. Their ‘Impossible’ not because it can’t be done, but because we don’t have a strong material to withstand the rotational force at that scale.

Yes, simplicity like that blows my mind. Math has in some degree destroyed the Teslas of the world, its made science less accessible to the budding geniuses.

No one has time machines as time doesn't exist except in people's heads. People use pattern machines to go back, electro-magnetic-spin pattern machines, as in what all matter is made of, the concepts of the electric, magnetic and spin fields knotted. Pons and Fleischman were unwittingly unwinding matter in their "jam jars" by closing off their rods from the rest of the multi-verse via these three fields, the electric and magnetic fields were partially locked out using the rod currents and the bubbling liquid shut down the spin part of the field and so the material partially unwound releasing its energy. The reason protons don't decay as the present particle theory says they should is because they are maintained by their connection to the rest of the multi-verse but shield them magnetically, electrically and spin-wise and they disappear across to the other side of the mirror to their anti-proton life going backwards in pattern and release a puff of energy in this reflection going forward. The same thing happens with people who "shuffle off this mortal coil" and go back in pattern in a never ending cycle of death in this reflection followed by rebirth on the other side and on and on and on. Tesla would understand it but Einstein was as thick as two short planks. Religion is about freeing us from this cycle and bringing us all to the here and now.

Um... Do an industrial application of power generating you wouldnt "NEED" a disk that is 3 meters in radius. You would aimply need more cells in an array of .3-1 meter turbines. Duh!. And we have the material tech now days to make such things. The reason why this is being rejected is because Nuclear would be almost obsolete if they started making hydro electric of coal burning steam electrical generation.imagine, if you will, having a car where you use a small pump the supple plain and simple water through one of these ultra high efficiency turbines. Thich then turned and generated a massive amount of electricity. Which, with modern, science, technology, electrical etc, would produce more than enough energy to turn the motor which turned the driveshaft... Which tas an integral part of the pump. So basically, the pump moves the water through the turbines, the turbines generate electricity which runs the motor which moves the drive shaft to the wheels, which moves twater through the pump.
If your invention can't even be realized more than 100 years later and by the time it WOULD become feasible, it would be obsolete, then your invention is useless for practical application.
No, it's a way of saying it's not worth the effort. We can suppose there's a material yet to be invented that would support the RPM needed to make these work. If we have to do 30 years of RnD to find it the project isn't worth doing. Items like parachutes were mathematical sounds in Leonardo da Vinci's time. Yet it took modern materials to make it. No one sat down and tried to make the idea work. The original project was forgotten in time. This too was a project forgotten to time. Many engineering projects are physically possible but not worth the effort. Engineering isn't physics, it's applied science and the human part application is important.
@@gregheffly With the exception that in this case, If we would be able to create materials strong enough to withstand the RPM.....this kind of turbine would be obsolete. A parachute hasn't become obsolete because a fitting material was found and is hence a bad analogy.
@@gregheffly Da Vinci's parachute was terrible and not used. Other inventors actually took his design and improved upon it, shortly after his time. Parachutes needed both better designs and motivation. They didn't understand the physics yet, and it wasn't until basic fluid mechanics was developed in the 18th century as well as hot air balloons that the modern design was attempted. I don't think this was forgotten to time, because its the limit of the angling, but you are completely right about the physically possible part. The other question is why do we want that level of RPM? It would induce efficiency on an industrial applications further down the line. To me it sounds like it would have more use in micro-form factors outside of steam where this would pick up efficiency again.
the premise behind da Vinci's parachute was using logs to form a support structure foe the wind to catch and be buffered through a funnel hole. that kind of idea for a parachute is long dead. the funnel hole was neat and taken but the support structure was terrible, and as time marched on we found out that a good design will capture air as its own support structure. this is a friction turbine, like the old parachute, there's an idea taken from this, then the rest is discarded. low slip boundary layers sounds is a good idea. the rest is trash

Great video! There is another basic turbine configuration that wasn’t mentioned. That is the API 611 solid wheel steam turbine which is commonly used in the petroleum industry. The design uses buckets machined into the outside of the wheel which enhance the power transmission capability of the drive over a straight up Tesla design. The advantage of the solid wheel API 611 turbine over conventional axial flow bladed turbines (which are more efficient) is that the solid wheel design can handle liquid slugs which are often present due to poor quality steam that falls below superheated temperatures as it is pumped to the turbine. It is hard to keep pressurized steam in the superheated state when transported from the boiler to the turbine.

Went to his house in Belgrade Serbia a couple years ago, it's a pretty awesome little museum with a bunch of his gadgets and working models you can interact with.
Tesla never lived in Belgrade, Serbia. You visited the museum. If you want to visit his house of birth where he lived before going to faculty (house turned into museum), you need to go to Smiljane in Croatia.
Last year I had study (Drag force) but I couldn’t understand very well and put it real life example . But just by watching this animation , now I know what I have studied before . Thank yu
I highly recommend anyone to look into Tesla’s life story- As well as many other things he was trying to create wi - fi way back in 1900s the man was a pure genius
I remember something about wireless electricity. There are phones that wireless charge today, but it's not very efficient if you consider it for household appliances. When you consider 8 watts vs 5 watts to charge a phone it seems less consequential though.
Honestly are you this fucking deluded by your lack of education ? There were MANY tecs of that era that KNEW that satellites were possible, in the 30 s they knew that mobile phones were possible. They knew computers were possible but the technology wasn't available
The Tesla turbine was supposed to produce his electrostatic compressional waves, it is necessary to get 30k RPM minimum. I understand now, how this is so much superior to what he was using before.
"electrostatic compressional waves" 4:31 how do those smiling balls hold hands? like what are their hands made of? what did they think those hands were made of in the 1900's? could be thought of as electrostatic forces? at 6:11 that is a pressure wave of steam could someone describe that as "compressional waves"? but your right produce is wrong if you think it means is the end result, it would have been extract or utilize, but if you use the word produce as a method such as the machine by producing a electrostatic compressional waves internally can harvest the energy from the steam, to do this in the best way it must spin at 50,000+ RPM. tesla's design is the "superior" one for efficiency we use we just lack the capability to build it. their is a story where Mozart/Beethoven I forgot which one made some fast music that could not be played on pianos of the time with out breaking them.
@@Amipotsophspond Tesla’s apparatus for variable high speed frequency was a way of producing high frequency static electric waves. The wheel turned by the turbine would need to have a wider diameter(maybe around 3 feet diameter) , and I believe Tesla said 400 tungsten pins on the outer perimeter, and one(more are possible if the frequency is timed correctly) on the apparatus. The pins should be positioned so that the gap is as small as practicable. When the turbine gets the wheel up to 35-50k RPM’s, the frequency would be 400 times greater. The speed of the air controllers the speed of the wheel....the wheel is with a charges, so all tungsten points have potential, only the one closest the opposing pin will discharge. In that way speed of the wheel can be maintained indefinitely, and only the friction of the bearings a heat consideration in the making of that high frequency
@@Amipotsophspond nothing I have said is commenting on the fluid dynamics explained in this video. Only how this apparatus was incorporated to his other high frequency/potential apparatus.
@@FireBeam I am not completely sure. You need a flat bifilar, and it should be made to the specs Tesla laid out. I spent two years figuring out how to make a very high quality flat bifilar. You need one spark(Tesla defined the spark as a crack- so even the spark from a static electric connection is sufficient), a spark. It can be in a vacuum, and it will take very little energy to initiate the spark. The spark must be interrupted around a million times per minute......well as a starting point. So a wheel that has an RPM of about 15,000-50,000 is of great value. If one affixes 400 tungsten rods of a perfectly even distance, between one another, and from the spark.....and then the air is variable, so the RPM can be varied.
engineers live between the rock of the laws of physics, and the stone wall of what the customer wants - literally a rock and a hard place, and its easy to get crushed between them. Just because something is possible, that does not mean it can be practical, or cost effective compared to another approach. For example, in the 1950s we thought in the future we will have flying cars and personal robots. We dont have personal robots like Rosy on the Jetsons, but we do have all sorts of computer controlled devices that take messages, look up information for us, wash and dry our clothes, cook our food and make bread without intervention, control the speed and braking and to some extent the steering of our vehicles (cars, trains, jets, helicopters...) We dont have one robot that does all those things, like Robbie in Forbidden Planet. Instead we have many devices that do things for us, so we dont have to.

@@ngotranhoanhson5987 I mean if we can reach the same efficiency at a fraction of the weight and complexity and we just need stronger material, the Tesla turbine would be the preferred turbine for anything where weight is a concern. If only we can engineer one.
@@TheBoyar so you Didn’t watch the video. Tesla’s design, wean scaled up to modern detentions, is nearly 2.5x more powerful than anything wear currently using. The reason wear Not using it is because we Still lack a strong enough material to withstand the generated rotational force.
@@cpowerbpower3339 if the idea was to replace modern turbines with sized up versions of Tesla’s than yes your correct. But consider Tesla’s stance on power generation and distribution.
He had the default of thinking too highly of himself and his ideas, as he was incapable of imagining he could be wrong. Without this default, he would have been much better. Many scientists have had a much larger impact on science.
Ikr, it would be so different from today and I believe this world would also be a lot better. He once stated too that in order to grow the overall human research, we ought to look into things spiritually and not just materially, so I believe a lot of things wouldn’t be that bad today
@@Ken19700 do some more research. You're right about that as well but Edison for sure had some government connections helping Jim out because he was an American and Nikola was a Croatian immigrant. The U.S. was a super nationalist country back in the day.
@@Afro.G. Looking at TH-cam videos and reading conspiracy theories is not research. No one in the US cared that Einstein was an immigrant, or Elon Musk for that matter. Read a book.
To reach the '97% efficiency' that he claimed, Tesla set up a design with secondary or even tertiary turbines. The outlet of the first flowing into the inlet of a secondary turbine and so on. It's a great design that is underused for turbines and especially for pumps.
@Zakarii Tsuki idk lol. Same point either way. Rather they make it themselves or find someone else that can. Didn't feel getting that far into the specifics really mattered.
I remember seeing photo's of a Tesla technology motor, what was really most surprising was not the ten horsepower rating, the surprising thing was that it would fit into the palm of your hand.
Tesla is the only badass to ever live. Never wrote anything down, never stole credit from anyone, and never sold out no matter how many billions they threw at him. He was 1 of a kind.
You're right except for the "never wrote anything down." He made drawings, notes and schematics. The US government confiscated ALL of his papers within hours of his death. He didn't need to write things down as he was able to design, test and re-test in his mind but he did keep records.
I wish Tesla had not been beat out by Edison. We would be way ahead of where we are now in technology. We should test and investigate all of his notes, inventions and research. He was a genius - and competition destroyed him.
No we wouldn't. Almost none of Tesla's inventions actually work in reality. If he'd "beat" Edison, we'd still be scratching our heads trying to make his seemingly genius but practically or literally impossible inventions work rather than having improved the airfoil turbine little by little over the years until we achieved something 95% as good and enjoyed ever-improving lifestyles all the time rather than being stuck waiting around for Tesla's problems to be solved. The vast majority of technological progress has been made in steps, not in breakthroughs.
I'm not a mechanical engineer but i took some physics related courses in college. So, I think this video is pretty interesting. Makes me wanna take some more classes from a mechanical engineering department.
I like how the RPM of the 3 meter disk was assumed and not the fluid flow velocity. Since the turbine works on skin friction, the average speed of the disk cannot exceed the average speed of the fluid. At the tips, if the disk is spinning faster than the fluid, then the fluid will actually be slowing it down rater than speeding it up. You could have just said that you would need the fluid to flow at Mach 18 to spin the disk fast enough, and that's assuming the material could handle the centripetal forces, which they can't. There's no way we are making a hypersonic fluid flow contained in a pipe in the first place, regardless of if the disk could handle the forces. It's a non starter on multiple fronts.
The problem started for me when he quotes rpm for the tesla then says mach speeds to compare the current turbine blade tips speeds. Fact 1: the 6" tesla needed to spin at 30000rpm to be efficient at 6" diameter, but a 6 foot diameter turbine doesn't need the same rpm to have the same speed at its outer edge which is the crucial factor. Big turbines don't need the same rpm as small ones, no matter what type.
Leonardo Da Vinci had the same problem with the inventions that he devised on paper. Many would have worked except he didn't have the right materials to make them. Tesla a man ahead of his time.
When you're making progress things break. Always a good sign, interesting though most people don't see it that way. Also evident with the repost of this video. Keep up the great work Lesics your on your way to becoming one of the top channels in your field.
So basically Tesla turbines are analogous to reversible heat engines. With heat engines, you can transfer heat from hot chamber to cold chamber, extracting work. Or put in work, and move heat from cold chamber to hot chamber. Tesla turbine moves fluid from high pressure chamber to low pressure chamber, extracting work. Or, if work is put in, it can move fluid from low pressure chamber to high pressure chamber. In essence, the Tesla turbine is a pressure engine, the P-domain counterpart to the heat engine's T-domain.
It's amazing how he made inventions that we just didn't have materials for at the time, This makes many of his inventions future-proof, Meaning when we get stronger materials like we have today, We can use them!
@@DStanford94 Well we probably have more than that on the planet currently. The sad thing is that theres a high chance the most geniuses are living in some poor rural area where they can never reach their potential
@@CptUhudini Nothing hard about building flying cars. The problem with all crackpot ideas is the basic laws of Physics.

Even with the most powerful computer and positioning satellites nothing can predict the unpredictable and what other influences can occur. No insurance company would ever insure your flying car.
At 7:50 he compares the diameter to a modern steam turbine. Wouldn’t a true comparison be comparing the torque output regardless of the size? Like what if a Tesla turbine only needed to be 1.5 meters to do the job a 3 meter modern turbine could do.
@@prowhiskey2678 I work on jet engines and my best guess would be materials still. We have a small engine that does 40-60k rpm but the diameter of its rotor is around 6-8 In blades included. Last time I heard of one of those letting go it sawed the engine in half and left 2 inch dimples in the top of the enclosure. The walls of the enclosures for those engines are made of 1/2in steel with a sound deadening material held in place by a perforated metal sheet. One chunk went through a window and passed through a set of standup lockers (think high school hall lockers) 8-10 ft from the engine before imbedding itself in a file cabinet well beyond that. If we have that much trouble with something that small I don't want anywhere near a 5ft rotor doing 40-50K... Plus I kinda question how long it'd take to get it spinning that fast. Thats a lot of mass to get moving. Then if you need it stopped though if you start pushing liquid the other way... ok stopping may be easier but still lot of mass to slow. At this point I think we still need to be working on a material that can withstand that level of force first. Though strangely I've slowly been questioning if metal is the right direction for some things. Yeah the properties of it are great but is there something we've been missing elsewhere. I know composites aren't there yet but that's an example of looking elsewhere. Sadly my answers for that are probably either 60years or one solid alien invasion off
@@Dawgsofwinter what kind of material were they using? I’m wondering if there is a material available but that it’s too costly to be viable. I also wonder if a type of carbon fiber disc might be better.
@@andrew5576 Not sure off the top of my head and frankly too lazy to dig through manuals to be certain. But the I'm pretty sure the rotor isn't anything to exotic or such and I'm positive the casing isn't either. I know some of the engine is titanium but which parts yeah. The Hot sections have a few oddball metals but frankly you'd be amazed what you can do with properly directed air to keep things from getting hotter than they should. @TheChzoronzon you haven't been around some truly insane fanboys then have you... Life's not fun till you hit a Telsa coil show. And if you wanna try one at home ya gotta know enough about physics to pretzel em enough to be awesome without being fatal.
Problem: The U.S. electrical grid operates at 60 Hz, which means that, at any given moment, the electrical generators hooked up to it generally *must* spin at 3600rpm to correspond to the induction/magnetic field between the rotor and stator. A generator being spun at tens of thousands of RPM would not even be compatible with the Hertz and phasing of the electric grid. You would have to add some sort of complex gearbox (again made out of wonder-materials) between the turbine shaft and the generator shaft to reduce generator rpm. And that extra gearbox would result in a loss in overall efficiency. And as others have mentioned, not only would the discs, themselves, have to have wonder-material-strength, so would the bearings holding up the shaft, and the lubrication within that bearing, and the seals where the spinning shaft penetrates the turbine housing. The lube system might have to get more complex as well to carry enough heat away from the bearings (extra heat exchangers, etc). The overall system would not necessarily be more simple than current systems just because one component (discs) are more simple than another component (blades).
@@jesseprete2792 but according to the video, that limits your efficiency, which defeats the whole point. in order to get their miraculous (theoretical) efficiency numbers, the speed needs to be high.
@@jesseprete2792 I believe worm gears would do wonders to reduce RPM greatly with the fewest fast spinning parts. There are materials of extreme strength for heat and friction, particularly fluid friction for fighter jets. They're also unfortunately difficult to machine but sure would be awesome to somehow get discs flat enough. Just did some googling and I wonder if making half discs with coolant flows machined out so that when they're put together coolant can run through the disc and keep it thermally stable. Kinda wanna try it now.
I'm not an expert but I've been told that because of the failure rate no bank will give you a loan for a wind turbine that has a gearbox. We have a little 6kw turbine with three phase AC output. The frequency of the AC will depend on the wind speed so it's all rectified to DC, merged together, and then through an inverter to 50hz AC. It can then sync with the grid and it makes about £6000 ($8283) per year, it's windy here!
Possible options. But similar to a gearbox, every time you convert energy form, there are energy losses. So best case scenario, you max out at 3% losses through the Tesla turbine, then maybe 5% losses through the electric generator it spins, then 20% losses through the rectifier, then 5% losses through the inverter, before you reach your step-up transformer (which has its own losses) and go to the grid. So your 97% efficiency has dropped down to 70% or lower. And the extra equipment adds complexity and expense.
viscocity is beautifully described with the interesting animation... great and great...i am a fan of this team!...i feel sometimes, we missed such teaching aids to understand the concepts of physics... when i was studying engineering... may be we would have understood much better...however no regrets!
Thats a good way of putting it, in fact this can be an advantage in high volume thruput setups where stealing a portion of the heat with high thruput becomes an excellent device
There is a very fundamental difference between torque converter and Tesla turbine. Torque converter doesn't depend on the viscosity of the working fluid. Tesla turbine wholly depends of the viscosity to couple the moving fluid and discs.
As a member of The Domain with the bulk of his spiritual being on Space Station 33 in the asteroid belt at the time of animating the body of Tesla, it’s perfectly natural what he did. Just imagine what you could do with your spiritual memories from previous lives intact.
Even if we find materials like that and can manufacture it precisely enough, it would still not be a good idea. while the turbine may get 97% efficency you still need 3000 RPM (or 3600 RPM if you have 60 Hz system) to run the generators, witch will need some sort of transmission (with losses). The conventional steam turbins usually run at 3000/3600 depending on region, so there's no need for a transmission, just couple the geneator directly. (that's because synchronous motors spin at exactly the frequency of the power they generate) Yes, the turbine is efficent, but it's characteristic is not suited for supplying the grid with power
I think it could have small scale application, assuming better materials, small enough that it wouldn't need large radius disks. Single house power generator, or maybe for a yacht. Combine it with a furnace heater to also provide power.
@@martinxXsuto I would think a gearing mechanism would be simpler than all the complexity of a bladed turbine. Not that a Tesla turbine + gearing mechanism is super simple, but it's hard to be more complicated than a conventional bladed turbine. I'd want a more in-depth analysis than a comments-section armchair critique to make up my mind. But I have a hard time imagining a Tesla turbine + gearing mechanism would have more moving joints, nevermind more parts.
@@Minecraftgeek not a physics major but im pretty sure if you had one of those discs break off at max speed it would slice through multiple feet of solid concrete, or explode
I was part of team that built one of these for an Airforce design competition in college. We could reliably get ~94% efficiency with a closed loop superheated steam system harvesting exhaust heat from a small jet engine and got just below 96% efficiency in some ideal test cases. The main limiting factors were that the discs had to be designed to stretch uniformly without distorting at ~40k RPM and that the gaps between the disks had to be designed for an incredibly specific set of operating parameters (steam temp, pressure, velocity, etc.). The smallest variations, or while waiting for it to spin up, and we wouldn't even get close to those efficiencies. A lot of the initial designs weren't efficient enough to reach the right parameters at all.
Oh boy this warrants so many follow-up questions:
- Dual outlet or single?
- How many discs were used per outlet?
- What geometries were used in the outlet?
- What diameter went with that RPM?
- What was the measured torque output?
- Was (or how was) the design compounded?
- What materials were used for the discs that had those properties?
- Stated efficiency is presumed mechanical, how'd you calculate that efficiency? Was it measured output vs measured losses after the outlet?
- What was the name of the competition? Who did you represent or were associated with? I want to find it online or know what I'd need to file a Freedom of Information request with the government because having access to those results would be a game changer for anyone seeking investment in the technology.
I'm not looking to call you a liar but you did just say you'd achieved well over twice anyone else's stated efficiency numbers. While I can imagine what you're saying could be true it's still well beyond what anyone has actually demonstrated. So "extraordinary claims = extraordinary evidence" still applies here. Nothing personal! :)
@@Cheebzsta Nah dude I was there. It's true
@@consumemilk8005 Not a valid answer
@@Cheebzsta
Want in on this info
@@Cheebzsta Honestly, it was years ago and I don't remember most of the details but I'll give you what I got.
-It used an exhaust manifold with a single exhaust port going into the turbine. The port was also optimized for laminar flow over the disks. The turbine had dual axial exhausts which recombined in a baffle at the manifold's intake.
-Around ~15 disks, can't remember exactly.
-Turbine exhaust was a circular cut around the axle, broken up by three supports with rounded chamfers. The disks mimicked that but were individually keyed to give the ports a slight offset. The offset actually eked out a bit more (read as "miniscule") efficiency in testing, likely due to artificial radial extension of the fluids path toward the axle.
-Around ~10in diameter disks.
-Not sure exactly how this design came about except our professor was interested in a practical execution of the turbine and it fit the competition requirements.
-The disks were made of a pre-stressed stainless steel alloy. They were individually laser cut then tested at expected RPMs for any unexpected deformations. The vast majority of all disks didn't meet our specs and got tossed out. I think we could only use about 1 in 20 disks by the end of it.
-It was primarily a mechanical efficiency and as soon as you throw an alternator on there it's a completely different story. It was measured relative to the steady-state properties of the steam at turbine intake vs turbine exhaust and the kinetic energy of the disks and axle. We measured efficiencies throughout the entire system but that one was the main focus. The most inefficient part of the system was just heating the steam with the jet exhaust without impacting its thrust too much. Surprisingly difficult to do. There was a fair amount of doctoral research on tesla turbines that we used as the basis of our design and which achieved similar efficiencies but it was all at similar or smaller scales. For the amount of effort there aren't really any practical applications for a turbine like this.
-I can't remember the name but it's an annual competition (different goals each year) based out of Wright-Patterson AFB in Dayton, Ohio. This one was in 2014 and we were representing the University of Michigan Aerospace Engineering department. It was a shockingly informal process so I'm not sure how much info you could find but if you do look into it and find anything let me know. I'd love to revisit it all.
Tesla's genius was finding solutions to problems. By doing so, he also created a few problems which, therefore, made him even more inventive.

No it does not, they should have performed actual experiments to back up what they're saying instead of cartoons. Cartoon videos, like NASA, does not prove anything. Shill TH-camr exposed.
I want to add it here so it is visible. But there is actually a way to make the Turbine 10x smaller, but using the "Super Critical Carbon Dioxide."
It is a real thing that they can make regular turbine 10x smaller.
Another thing that people don't mention. There are 3 inventions on the same shaft:
1. Tesla turbine (takes steam and spins it)
2. Tesla pump (Propels moleculs from the center outwards, creating a vacuum)
Both amplify one-another.
3. Air-bearing on both sides. The vacuum-pumps on both ends give more power to the Tesla turbine in between them, and also create a suction for the air-bearings.
There are videos of people literally FREEZING steam using the Turbine and Pump in combination. By having the math on all of these right, you can achieve perhaps 99% efficiency. By using the Super Critical Carbon Dioxide, you can down-size it 10x.
You can have a look at the video by a man way more knowledgeable than most men or women out there, on this issue:
"A Better way to Make Electricity WITH CO2"
I was a new graduate electrical engineer at Allis-Chalmers Corp. at the research division in West Allis, WI in 1961. At that time, A-C owned the Tesla turbine patent, and I worked beside a fellow mechanical engineer who had been assigned the task of running tests on a compressed air driven Tesla turbine. To load the turbine, a war surplus B-29 engine turbocharger [A-C had made these during WWII, and a few were still lying around] was shaft driven by the test Tesla turbine. A-C was one of the USA manufacturers of steam turbines at that time, and therefore the performance of the Tesla turbine was of interest. After the tests, a full report was written, but is probably lost today, as A-C went out of business in 1986. I am happy to see that others have pursued testing of the Tesla turbine, and have added to the knowledge base. As an interesting side note, Nicola Tesla himself was hired by A-C as an engineering consultant in the early 20th century as revealed in a report on file that my fellow engineer found in the A-C archive. As is well known, Tesla was rather eccentric in his habits. He could not stand to stay overnight in West Allis for some reason, spending his nights out in suburban Waukesha, and commuting by electric rail each workday to the West Allis works. That report too is probably lost.
Interesting history remark. What applications do you think the turbine is best suited for in the power industry?

Thank you Lesics for featuring my "garage project"
Here are some info about the "why did you do it, dude?" topic:
It was just a proof of concept prototype, which was built to show some people that it works efficiently and safely with compressed air.
It was completely home made, that is why it is so robust and crude. I had to be sure that it does not fail, despite being built from cheap brass. Also it had to be self adjusting because I had no way of machining and assembling it with micron precision. I did not have the tools and means to balance the rotor, so it had to be as close to perfect "out of the box" as it was possible. The ceramic ball bearing has a high tolerance which I had to take into account too.
I used a 3D printed replaceable nozzle insert, which is easy to adjust to the actual application and parameters. Not to mention how much easier it made the manufacturing.
36000 rpm means about 95 m/s blade edge speed at 1 bar pressure with no load... the theoretical maximum is about 80% of sound speed (without some special nozzle and disk geometry), which is 270 m/s, so I achieved 35% of the possible RPM. With better design and this turbine size the theoretical speed is 100 000 RPM and about 600 watt output with 2.5 bar dry air pressure.
This crude prototype run with roughly 45% efficiency at 2 bar pressure (280 watt measured electric power on the brushless motor contacts)
I made a 2.0 advanced design for the real application, but that requires expensive machining equipment and special materials (I pushed it to the limit)
This one is simple and uses some very basic geometry for easy build.
Technical stuff:
Disc diameter 50 mm
Disc thickness: 0.1 mm
Gap: 0.2 mm
3D printed PLA intake nozzle with multipoint output
5 stabilizer pins at the edges, riveted with gap spacers.
4 mm diameter steel axes
Ceramic ball bearing
Exhaust on both axes directions
Brushless motor used as generator with 3 phased output
(Maxon ECX-19 high speed motor with ceramic ball bearing)
Power output 280 watt at full load. Loaded RPM 18000 RPM

Its wild knowing he sometimes had trouble distinguishing reality from the thoughts in his own head. He was basically a genius who was hallucinating in his everyday life
Sleep deprivation will do that to you.
Not wild at all, he was just a bit weird.
He had a tendency to mix religious zealotry with engineering on occasion in ways that just made him sound like a lunatic.
The truth is that he was a decent engineer, perhaps even gifted.
But not a genius.
If Galileo Ferraris had Westinghouse's ear before Tesla then he would be a nobody today.
Westinghouse made Tesla, in return Tesla turned around after his death and promptly erased Westinhouse's entire contribution to the electrification effort all while heaping the glory on himself - it's actually pretty tragic.
Basically everything positive that popular media says about Tesla is down to other people, mainly Westinghouse and Ferraris.
I think he was untethered from what we call "reality". But if we're being honest, our "reality" is very much just a limiting view of the universe in which we try to contextualise EVERYTHING, so that it makes sense from our very limited perspective. I think Tesla was ego-less and therefore able to see limitless realities that he was comfortable knowing he couldn't comprehend.
He needed a lab. For his ideas. He should have kept working with Westinghouse.
well he had OCD
Finally someone fully explained why we don't use Tesla turbines in powerhouses. I work on steam turbines in the powerhouses during shutdowns. Most of the engineers I have talked with didn't even know what a Tesla turbine was, let alone why we didn't use them.
That might change once material science improves.
Why not use gearing to lower the rpms
Tesla the only known man who had basically the 3D CAD in his head, namely when he was asked why his machinery in almost all of the cases worked out first time. He replied because I assembled them in my head and try multiple variations until it work in my head only then I build tem in a RL .
That statement was on the trail when his lab suddenly burned without any reason (Edison ..? ) with all the documentation in it.
Tesla was shocked but he rebuild all of his machines out of his head in 2 months, it was a real miracle for his co workers, they wrote later that this was basicaly impossible task it should take 2 years not 2 months

This actually helped me figure out pressed fuse glass. You can make glass really thin by pressing it between two kiln shelves, but the thinner it gets, the more it pulls on the kiln shelves, and the more it picks up kiln wash/kiln paper (intended to keep glass from just gluing to the kiln shelves. 3/16" or 4.5 mm can be pressed without destroying the kiln wash coating. 2.5mm cannot.
Glass does have a surface tension and "wants" to be about 6 or 7mm thick.
Maybe float your glass on a molten metal? I work glass mostly on a propane/oxygen torch, have tried a little fusing here and there. At some point I saw some videos or toured an old factory (memory is faulty). I think they used lead or tin .
@@RedSeedlesslive The surface tension determines glass thickness. Floating on metal will make it 6-7mm thick.

If we had time machines, I would love to use one to bring Tesla to the future so he could continue his experiments with new tech. Man was a legend of his time and I bet if he lived today he would make something even greater.
I suspect the technologies of the future would be too much for him actually. Guy had a history of taking credit for others work and doing things entirely freestyle without actually understanding what he was working with.
Not to say he was entirely clueless,... the guy was brilliant. But in a mad scientist sort of way. Thats probably why people like him,.. he is far from the standard when it comes to brilliant minds.
But he'd blow himself up without a doubt.
Although I do have to admit, I am also curious what he would come up with before he met his certain doom.
To amend what I said tho, out of fairness... most inventors and brilliant minds of the past, and even today, stole the ideas and/or work of others and claimed it as their own. So take it however you will :/
I already went back in time and accomplished this feat. Ofc Tesla changed his name so as not to seem creepy being alive/dead at the same time. He now goes by Mike Lindell. I hope this helps you sleep better!
No one has time machines as time doesn't exist except in people's heads. People use pattern machines to go back, electro-magnetic-spin pattern machines, as in what all matter is made of, the concepts of the electric, magnetic and spin fields knotted. Pons and Fleischman were unwittingly unwinding matter in their "jam jars" by closing off their rods from the rest of the multi-verse via these three fields, the electric and magnetic fields were partially locked out using the rod currents and the bubbling liquid shut down the spin part of the field and so the material partially unwound releasing its energy. The reason protons don't decay as the present particle theory says they should is because they are maintained by their connection to the rest of the multi-verse but shield them magnetically, electrically and spin-wise and they disappear across to the other side of the mirror to their anti-proton life going backwards in pattern and release a puff of energy in this reflection going forward. The same thing happens with people who "shuffle off this mortal coil" and go back in pattern in a never ending cycle of death in this reflection followed by rebirth on the other side and on and on and on. Tesla would understand it but Einstein was as thick as two short planks. Religion is about freeing us from this cycle and bringing us all to the here and now.

Um... Do an industrial application of power generating you wouldnt "NEED" a disk that is 3 meters in radius. You would aimply need more cells in an array of .3-1 meter turbines. Duh!. And we have the material tech now days to make such things. The reason why this is being rejected is because Nuclear would be almost obsolete if they started making hydro electric of coal burning steam electrical generation.imagine, if you will, having a car where you use a small pump the supple plain and simple water through one of these ultra high efficiency turbines. Thich then turned and generated a massive amount of electricity. Which, with modern, science, technology, electrical etc, would produce more than enough energy to turn the motor which turned the driveshaft... Which tas an integral part of the pump. So basically, the pump moves the water through the turbines, the turbines generate electricity which runs the motor which moves the drive shaft to the wheels, which moves twater through the pump.
“Engineering impossibility” is another way to say “we haven’t figured it out yet”
If your invention can't even be realized more than 100 years later and by the time it WOULD become feasible, it would be obsolete, then your invention is useless for practical application.
No, it's a way of saying it's not worth the effort.
We can suppose there's a material yet to be invented that would support the RPM needed to make these work. If we have to do 30 years of RnD to find it the project isn't worth doing.
Items like parachutes were mathematical sounds in Leonardo da Vinci's time. Yet it took modern materials to make it. No one sat down and tried to make the idea work. The original project was forgotten in time.
This too was a project forgotten to time.
Many engineering projects are physically possible but not worth the effort. Engineering isn't physics, it's applied science and the human part application is important.
@@gregheffly With the exception that in this case, If we would be able to create materials strong enough to withstand the RPM.....this kind of turbine would be obsolete. A parachute hasn't become obsolete because a fitting material was found and is hence a bad analogy.
@@gregheffly Da Vinci's parachute was terrible and not used. Other inventors actually took his design and improved upon it, shortly after his time. Parachutes needed both better designs and motivation. They didn't understand the physics yet, and it wasn't until basic fluid mechanics was developed in the 18th century as well as hot air balloons that the modern design was attempted.
I don't think this was forgotten to time, because its the limit of the angling, but you are completely right about the physically possible part.
The other question is why do we want that level of RPM? It would induce efficiency on an industrial applications further down the line. To me it sounds like it would have more use in micro-form factors outside of steam where this would pick up efficiency again.
the premise behind da Vinci's parachute was using logs to form a support structure foe the wind to catch and be buffered through a funnel hole.
that kind of idea for a parachute is long dead. the funnel hole was neat and taken but the support structure was terrible, and as time marched on we found out that a good design will capture air as its own support structure.
this is a friction turbine, like the old parachute, there's an idea taken from this, then the rest is discarded. low slip boundary layers sounds is a good idea. the rest is trash

Great video! There is another basic turbine configuration that wasn’t mentioned. That is the API 611 solid wheel steam turbine which is commonly used in the petroleum industry. The design uses buckets machined into the outside of the wheel which enhance the power transmission capability of the drive over a straight up Tesla design. The advantage of the solid wheel API 611 turbine over conventional axial flow bladed turbines (which are more efficient) is that the solid wheel design can handle liquid slugs which are often present due to poor quality steam that falls below superheated temperatures as it is pumped to the turbine.

Went to his house in Belgrade Serbia a couple years ago, it's a pretty awesome little museum with a bunch of his gadgets and working models you can interact with.
Wow thats sounds very cool!

I see what u did there
@@void-9 That même always puzzled me since what he actually says in that episode is "hassen" / はっせん / 八千 which is 8000.
I highly recommend anyone to look into Tesla’s life story- As well as many other things he was trying to create wi - fi way back in 1900s the man was a pure genius
And the father of Radio Control. He was a huge believer in energy transmitted through the air. In other words the world all around us today.
I remember something about wireless electricity. There are phones that wireless charge today, but it's not very efficient if you consider it for household appliances. When you consider 8 watts vs 5 watts to charge a phone it seems less consequential though.
@@TimpBizkit It's sad he's mostly remembered for this one failed invention and obsession, not for his real and numerous contributions.
@@guesswho6038 he was a tragic character for sure. such a waste of greatness
Honestly are you this fucking deluded by your lack of education ? There were MANY tecs of that era that KNEW that satellites were possible, in the 30 s they knew that mobile phones were possible. They knew computers were possible but the technology wasn't available
The Tesla turbine was supposed to produce his electrostatic compressional waves, it is necessary to get 30k RPM minimum. I understand now, how this is so much superior to what he was using before.
"electrostatic compressional waves" 4:31 how do those smiling balls hold hands? like what are their hands made of? what did they think those hands were made of in the 1900's? could be thought of as electrostatic forces? at 6:11 that is a pressure wave of steam could someone describe that as "compressional waves"? but your right produce is wrong if you think it means is the end result, it would have been extract or utilize, but if you use the word produce as a method such as the machine by producing a electrostatic compressional waves internally can harvest the energy from the steam, to do this in the best way it must spin at 50,000+ RPM. tesla's design is the "superior" one for efficiency we use we just lack the capability to build it. their is a story where Mozart/Beethoven I forgot which one made some fast music that could not be played on pianos of the time with out breaking them.
@@Amipotsophspond Tesla’s apparatus for variable high speed frequency was a way of producing high frequency static electric waves. The wheel turned by the turbine would need to have a wider diameter(maybe around 3 feet diameter) , and I believe Tesla said 400 tungsten pins on the outer perimeter, and one(more are possible if the frequency is timed correctly) on the apparatus. The pins should be positioned so that the gap is as small as practicable.
When the turbine gets the wheel up to 35-50k RPM’s, the frequency would be 400 times greater. The speed of the air controllers the speed of the wheel....the wheel is with a charges, so all tungsten points have potential, only the one closest the opposing pin will discharge.
In that way speed of the wheel can be maintained indefinitely, and only the friction of the bearings a heat consideration in the making of that high frequency
@@Amipotsophspond nothing I have said is commenting on the fluid dynamics explained in this video. Only how this apparatus was incorporated to his other high frequency/potential apparatus.
Like a Van der Graaf static generator?
@@FireBeam I am not completely sure. You need a flat bifilar, and it should be made to the specs Tesla laid out. I spent two years figuring out how to make a very high quality flat bifilar.
You need one spark(Tesla defined the spark as a crack- so even the spark from a static electric connection is sufficient), a spark. It can be in a vacuum, and it will take very little energy to initiate the spark. The spark must be interrupted around a million times per minute......well as a starting point. So a wheel that has an RPM of about 15,000-50,000 is of great value. If one affixes 400 tungsten rods of a perfectly even distance, between one another, and from the spark.....and then the air is variable, so the RPM can be varied.
Very well done video. Thanks for sharing

This is an engineering challenge, not an impossibility.
Thank you for saying that, beat me to it 😉
engineers live between the rock of the laws of physics, and the stone wall of what the customer wants - literally a rock and a hard place, and its easy to get crushed between them.
Just because something is possible, that does not mean it can be practical, or cost effective compared to another approach.
For example, in the 1950s we thought in the future we will have flying cars and personal robots.
We dont have personal robots like Rosy on the Jetsons, but we do have all sorts of computer controlled devices that take messages, look up information for us, wash and dry our clothes, cook our food and make bread without intervention, control the speed and braking and to some extent the steering of our vehicles (cars, trains, jets, helicopters...)
We dont have one robot that does all those things, like Robbie in Forbidden Planet. Instead we have many devices that do things for us, so we dont have to.

He had the default of thinking too highly of himself and his ideas, as he was incapable of imagining he could be wrong. Without this default, he would have been much better.
Many scientists have had a much larger impact on science.
If only Tesla could've lived the life he deserved instead of being destroyed by Edison's government connections. Our world would be AMAZING!
Ikr, it would be so different from today and I believe this world would also be a lot better. He once stated too that in order to grow the overall human research, we ought to look into things spiritually and not just materially, so I believe a lot of things wouldn’t be that bad today

To reach the '97% efficiency' that he claimed, Tesla set up a design with secondary or even tertiary turbines.
The outlet of the first flowing into the inlet of a secondary turbine and so on.
It's a great design that is underused for turbines and especially for pumps.

So cool. I've never looked into this before. Pretty amazing that it's just flat discs.
Tesla is the only badass to ever live. Never wrote anything down, never stole credit from anyone, and never sold out no matter how many billions they threw at him. He was 1 of a kind.
You're right except for the "never wrote anything down." He made drawings, notes and schematics. The US government confiscated ALL of his papers within hours of his death. He didn't need to write things down as he was able to design, test and re-test in his mind but he did keep records.
@@tedunguent156 ^^^ this...
I wish Tesla had not been beat out by Edison. We would be way ahead of where we are now in technology. We should test and investigate all of his notes, inventions and research. He was a genius - and competition destroyed him.

No we wouldn't. Almost none of Tesla's inventions actually work in reality. If he'd "beat" Edison, we'd still be scratching our heads trying to make his seemingly genius but practically or literally impossible inventions work rather than having improved the airfoil turbine little by little over the years until we achieved something 95% as good and enjoyed ever-improving lifestyles all the time rather than being stuck waiting around for Tesla's problems to be solved. The vast majority of technological progress has been made in steps, not in breakthroughs.
@@QuesoCookies youre full of it.. MOST of modern power plants, generation and distribution are ALL Tesla designs..
I'm not a mechanical engineer but i took some physics related courses in college. So, I think this video is pretty interesting. Makes me wanna take some more classes from a mechanical engineering department.
I like how the RPM of the 3 meter disk was assumed and not the fluid flow velocity. Since the turbine works on skin friction, the average speed of the disk cannot exceed the average speed of the fluid. At the tips, if the disk is spinning faster than the fluid, then the fluid will actually be slowing it down rater than speeding it up. You could have just said that you would need the fluid to flow at Mach 18 to spin the disk fast enough, and that's assuming the material could handle the centripetal forces, which they can't. There's no way we are making a hypersonic fluid flow contained in a pipe in the first place, regardless of if the disk could handle the forces. It's a non starter on multiple fronts.
*ehem*
Vibranium 🥴
The problem started for me when he quotes rpm for the tesla then says mach speeds to compare the current turbine blade tips speeds. Fact 1: the 6" tesla needed to spin at 30000rpm to be efficient at 6" diameter, but a 6 foot diameter turbine doesn't need the same rpm to have the same speed at its outer edge which is the crucial factor. Big turbines don't need the same rpm as small ones, no matter what type.
Never say there's no way, you spoil the fun of imagining what if there's a way it can be done!
What if you used "melted snow" as the fluid? Antarctic snow is very cold and when it melts, it's super pure.
@@greenwave819 snow is literally just water, i dont get your myths but theres nothing special about it
Just calculated (roughly) what a 200000 RPM turbo (big turbo) on a car had for it's "tip" speed and it came to about 2.7 Mach.
The blade design can handle the deformation, right?
@@mundymorningreport3137 They usually do, the bearings has the most wear.

When you're making progress things break. Always a good sign, interesting though most people don't see it that way. Also evident with the repost of this video. Keep up the great work Lesics your on your way to becoming one of the top channels in your field.
So basically Tesla turbines are analogous to reversible heat engines. With heat engines, you can transfer heat from hot chamber to cold chamber, extracting work. Or put in work, and move heat from cold chamber to hot chamber.
Tesla turbine moves fluid from high pressure chamber to low pressure chamber, extracting work. Or, if work is put in, it can move fluid from low pressure chamber to high pressure chamber.
In essence, the Tesla turbine is a pressure engine, the P-domain counterpart to the heat engine's T-domain.
Sterling engines come to mind.
@@TheTubejunky Yep, exactly. Only that this (Tesla Turbine) is pressure-based while Stirling Engines are heat-based.

Imagine he married and reproduced dozens of tesla. 😃😲
At 7:50 he compares the diameter to a modern steam turbine. Wouldn’t a true comparison be comparing the torque output regardless of the size? Like what if a Tesla turbine only needed to be 1.5 meters to do the job a 3 meter modern turbine could do.
Yes, with a rpm like 4 times higher, the disc can be a lot smaller
@@prowhiskey2678 I work on jet engines and my best guess would be materials still. We have a small engine that does 40-60k rpm but the diameter of its rotor is around 6-8 In blades included. Last time I heard of one of those letting go it sawed the engine in half and left 2 inch dimples in the top of the enclosure. The walls of the enclosures for those engines are made of 1/2in steel with a sound deadening material held in place by a perforated metal sheet. One chunk went through a window and passed through a set of standup lockers (think high school hall lockers) 8-10 ft from the engine before imbedding itself in a file cabinet well beyond that.
If we have that much trouble with something that small I don't want anywhere near a 5ft rotor doing 40-50K... Plus I kinda question how long it'd take to get it spinning that fast. Thats a lot of mass to get moving. Then if you need it stopped though if you start pushing liquid the other way... ok stopping may be easier but still lot of mass to slow.
At this point I think we still need to be working on a material that can withstand that level of force first. Though strangely I've slowly been questioning if metal is the right direction for some things. Yeah the properties of it are great but is there something we've been missing elsewhere. I know composites aren't there yet but that's an example of looking elsewhere. Sadly my answers for that are probably either 60years or one solid alien invasion off

But the I'm pretty sure the rotor isn't anything to exotic or such and I'm positive the casing isn't either. I know some of the engine is titanium but which parts yeah. The Hot sections have a few oddball metals but frankly you'd be amazed what you can do with properly directed air to keep things from getting hotter than they should.
@TheChzoronzon you haven't been around some truly insane fanboys then have you... Life's not fun till you hit a Telsa coil show. And if you wanna try one at home ya gotta know enough about physics to pretzel em enough to be awesome without being fatal.
Problem: The U.S. electrical grid operates at 60 Hz, which means that, at any given moment, the electrical generators hooked up to it generally *must* spin at 3600rpm to correspond to the induction/magnetic field between the rotor and stator. A generator being spun at tens of thousands of RPM would not even be compatible with the Hertz and phasing of the electric grid. You would have to add some sort of complex gearbox (again made out of wonder-materials) between the turbine shaft and the generator shaft to reduce generator rpm. And that extra gearbox would result in a loss in overall efficiency.
And as others have mentioned, not only would the discs, themselves, have to have wonder-material-strength, so would the bearings holding up the shaft, and the lubrication within that bearing, and the seals where the spinning shaft penetrates the turbine housing. The lube system might have to get more complex as well to carry enough heat away from the bearings (extra heat exchangers, etc). The overall system would not necessarily be more simple than current systems just because one component (discs) are more simple than another component (blades).
couldn't one just separate the discs enough to limit the speed?
@@jesseprete2792 but according to the video, that limits your efficiency, which defeats the whole point. in order to get their miraculous (theoretical) efficiency numbers, the speed needs to be high.
@@jesseprete2792 I believe worm gears would do wonders to reduce RPM greatly with the fewest fast spinning parts. There are materials of extreme strength for heat and friction, particularly fluid friction for fighter jets. They're also unfortunately difficult to machine but sure would be awesome to somehow get discs flat enough. Just did some googling and I wonder if making half discs with coolant flows machined out so that when they're put together coolant can run through the disc and keep it thermally stable. Kinda wanna try it now.
I'm not an expert but I've been told that because of the failure rate no bank will give you a loan for a wind turbine that has a gearbox. We have a little 6kw turbine with three phase AC output. The frequency of the AC will depend on the wind speed so it's all rectified to DC, merged together, and then through an inverter to 50hz AC. It can then sync with the grid and it makes about £6000 ($8283) per year, it's windy here!
Possible options. But similar to a gearbox, every time you convert energy form, there are energy losses. So best case scenario, you max out at 3% losses through the Tesla turbine, then maybe 5% losses through the electric generator it spins, then 20% losses through the rectifier, then 5% losses through the inverter, before you reach your step-up transformer (which has its own losses) and go to the grid. So your 97% efficiency has dropped down to 70% or lower. And the extra equipment adds complexity and expense.
viscocity is beautifully described with the interesting animation... great and great...i am a fan of this team!...i feel sometimes, we missed such teaching aids to understand the concepts of physics... when i was studying engineering... may be we would have understood much better...however no regrets!
Its almost like a viscosity based "clutch" system- Or more to torque converter in a way- Though always "slipping"
Thats a good way of putting it, in fact this can be an advantage in high volume thruput setups where stealing a portion of the heat with high thruput becomes an excellent device
@@randyboone9352 ok then…
Yes, similar principle to a fluid coupling.
There is a very fundamental difference between torque converter and Tesla turbine.
Torque converter doesn't depend on the viscosity of the working fluid.

But still, radius of 1.5 meter with an outer speed of mach 13.... a tiny wobble or any loose parts and it will cause a catastrophic event.
Even if we find materials like that and can manufacture it precisely enough, it would still not be a good idea.
while the turbine may get 97% efficency you still need 3000 RPM (or 3600 RPM if you have 60 Hz system) to run the generators, witch will need some sort of transmission (with losses).
The conventional steam turbins usually run at 3000/3600 depending on region, so there's no need for a transmission, just couple the geneator directly.
(that's because synchronous motors spin at exactly the frequency of the power they generate)
Yes, the turbine is efficent, but it's characteristic is not suited for supplying the grid with power
I think it could have small scale application, assuming better materials, small enough that it wouldn't need large radius disks. Single house power generator, or maybe for a yacht. Combine it with a furnace heater to also provide power.
@@martinxXsuto I would think a gearing mechanism would be simpler than all the complexity of a bladed turbine. Not that a Tesla turbine + gearing mechanism is super simple, but it's hard to be more complicated than a conventional bladed turbine.
