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 RUclipsr 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"
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.
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.
@@ricardobautista-garcia8492 he stated that himself in his autobiography. He was a boy in Lika (Croatia) and read a travel brochure about Niagara Falls which stated the flow rate and surmised that it was an untapped power potential.
I want to build one with a hollow axle for the exhaust, hopefully it'd be strong enough. There'd have to be small holes in the axle between disks, which may complicate the fabrication process
08:30 Yet theres a nutter who wants to launch satellites by this method! And other idiots who invested 100M in this impossible stupid idea! 🤦♂️🤣 If only any of them knew basics physics or could search on YT for this video etc!
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.
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
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.
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
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.

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

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.

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%!

@@DozenDeuce pulling a vacuum costs energy, which reduces the performance. I'm not sure how the energy is meant to be enhanced more than the forces are offering.
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.
If you go further down the rabbit hole of his patents you’ll find that he started chasing the efficiency, adding Venturi system that would drop pressure on the output and increase pressure on inputs.

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
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!
Making out of control machines is easy... but you need to be Tesla to be hailed for it in the XXI century. It's frightening how ole Nikola (a gifted engineer and a lousy "scientist" with mental issues) has gone from unjustly unknown to a cringey and hilarious Pop semi-God in just a couple decades.

Quick comment from a Psychology professor entirely ignorant of engineering principles. The graphics of this video are stunning, and make the whole process crystal clear. Thank you!
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.

If it was practical to apply that that would make it good, otherwise no good. That is the whole point.

@@xsystem1 there is a big difference between not understanding how things were made and not understanding how to use his designs to improve modern technology. Imagine how far behind we would be if not for AC or the induction motor.
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.

"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.

As I was taught at university it’s centripetal force acting towards the centre of the rotation but as the diameter decreases so the force therefore it is greatest at the maximum diameter!
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.
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 RUclips 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.
Hi, just a question. 0.4mm gap is mentioned, where did this dimension come from. The research I have seen indicates 0.5mm at low speeds up to 1mm over 40/45K RPM with anything under 0.5mm. .decreasing output. Cheers John
i would argue that teslas efficiency number is correct, just because it cant reach that in practice doesnt change that is its theoretical efficiency, you just need a lighter yet still strong material to make the parts out of, which may be possible in a future alloy
Yes. The guy who made this video is a bit on the negative side. I'm an inventor and I don't like to say that it can't be done but how can it be done and try it, see if it works. And can't you make smaller ones and string the output together? Can't you make room for expansion? Can't you find ways to cool it? Use liquid nitrogen to cool it, or ammonia. Ammonia while heated up becomes cold.
This video is one of the best. The graphics are crisp, colorful and elegant, like the old-school instructional videos of the by-gone era. Produce more videos like this please. This video has Disney-class graphics.
@Imjust Observing Tesla wasn't the brilliant genius people make him out to be. If this was such an amazing invention, why is it NOT in use anywhere in the US? This WOULD be the best generator for use in hydroelectric plants if it was truly as revolutionary as people claim it is. Please name one thing Tesla invented that has been used in mainstream production anywhere at anytime in history. You can't. None of his parents have ever had any practical or real world value. Nothing he invented remains revolutionary or has any lasting or profound effect on anything. Tesla died broke and alone in a hotel room where he was a recluse who believed aliens beamed the ideas in to his head. He had embezzled money from his most wealthy benefactor, diverting funds to other projects which is why he wound up in this position.
@@ehomelessvillageidiot3051 you do understand that he needed to sell patents to have any money and do you know about alternating current probably not since he invented it and we ARE using it today and it was immposible to make a bigger version of this turbine and you do see that it Is used today but not for their original purpose but instead it Is a pump.
@@alagui7894 One look at the wikipedia page for AC motor will tell you that Tesla wasn't the first by years. Don't get me wrong, he was a gifted inventor and decent engineer but BOY is he overrated in history.
@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.
What it seems unrealistic now as engineer could be kids play in the future. Tesla still ahead of our current time and we still has long way to go to catch the application of some of his concepts. Best regards and be safe
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.

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.
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.
@@wildfirekingdom9466 there are a hand full of other more viable options than using marble. thank god we dont live in the stone age. Modern alloy, ceramics and composites provide us ample opportunity to fab discs for steam duty like this at scale.
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.
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.
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.
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.
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.
The genius of Nicola Tesla is indescribable!!! A man well ahead of his time. Just imagine if this man was here today and have available to him today's materials and technology. Imagine Tesla working together side by side with Musk. What a wonderful world it would be.
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.
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
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.
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.
Great animations, and video. I just want to clear some stuff up, that model in the video was actually an 18" turbine. I have the cad drawings on my channel, modeled exactly after the turbine from the original blueprints in the museum. I am glad to be a part of bringing this technology to life. Hang in there to see this through, I'm nearly finished with the production models.
@@iEnergySupply I agree, the video, animation and illustration of the turbine's fluid dynamics are outstanding. As with all animations, they do not compare to the real apparatus. I am glad to see so many Tesla Turbine enthusiasts here working together to bring this technology into reality. With everyone sharing their understanding and expertise, we can all experience the world re-debut of the Tesla turbine after being suppressed for over one hundred years.Yes, let's bring this technology to life. Everyone, thank you
Nicola Tesla: "I am limited by the materials of my time." Scientists in the future: "Keep going, we still haven't found materials strong enough for your machine."
@@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.
I'm so glad someone actually talks about tesla turbine drawbacks as well, so many videos out these talking about tesla turbine like it's some sort of perfection that engineers are blind to
Why did I never heard of this guy at school? I'm 60+. the only ones were Einstein, lot about him, and Edison. Even in today's media and schools nothing about him. His name only came famous by Elon Musk and his electric cars (Tesla). But from what I have read until now, he was the genius.
The Problem is, his ideas did not fit the world's consumption based model. Anything that can not be sold is discarded or hidden from us until they find a way to sell it to us. We are lucky that Solar energy, Oxygen and Water (which we as a species can not live without) are still free and in our grasps (most countries at least). but future generations will pay for it because those organizations that are supposed to stop pollution will make sure of that (by not doing crap against pollution)
You've heard of Edison because he invented the corporate laboratory: success doesn't get the actual inventor as much, but failure doesn't cost them as much either, so it makes innovation-based businesses practical as an ongoing concern. Edison did actually invent some other stuff, but corporate labs are the really _important_ bit. As for Einstein, his theories effectively disproved some of how Tesla thought things worked- both of them thought quantum mechanics was bunk, but Einstein proved it by trying to disprove it, while Tesla just rejected it. Further, the stuff towards the end of his life didn't pan out, whether his death rays (mercury was involved in some, and unavoidable the usage would have been a disaster to the surrounding area), his wireless power distribution (there was no way to charge for it, and so no way to support it- further, he was aiming for _worldwide_ distribution, which effectively would require a worldwide empire to governmentally fund it), and likely various other things that I'm not thinking of. Finally, while he had a strong showman streak, he also tended to be secretive in some aspects, which resulted in some misconceptions about him even from his fans.
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.
You know you are onto something interesting when you build something and it OVER performs... It gets TOO fast or TOO strong. When its the material strength of the hardened steel that is holding it back. At that point, whatever it is; can be counted as an engineering marvel.
@I love you but For overperforming he meant that it was so powerful it didn't even work. It has not to do with expectations but with actual results: Tesla's expectations, as a scientist, was to build something that worked. He did, but worked too much haha
Engineering is the process of using technology to create the possible. If you come up with something brilliant but it doesn't work it is an engineering failure.
@@kennethfharkin It actually works though. Certainly it's not about practically using the turbine, but reaching that incredibly high speed. The turbine reaches it, and then starts to break, not allowing it to be used as a turbine.
@@TheTechmaster1999 Lowering the RPM lowers the efficiency making the design less efficient than a traditional turbine so... not really a solution. If something has to destroy itself at the point where it becomes efficient it really isn't efficient.
@@samueleproiettimicozzi8134 "It works" isn't exactly accurate. The theory is proven to be sound with efficiency increasing as predicted at higher speeds but the theory falls apart in execution. Tesla's turbine almost certainly never reached the optimal speed and would have destroyed itself well before nearing it. As an engineer myself I refuse to call anything an "engineering marvel" which flat out does not work and this thing doesn't if you are trying to use it as it was intended. Now it functions to some degree as a pump depending on the application but I doubt we will ever seen a Tesla turbine operate as people imagine at anywhere near projected efficiency given the material and manufacturing limitations likely to be present for at least another hundred years and if we ever overcome those limitations a more suitable solution will have already be developed.
Instead of making them wider, just add more discs sideways. Car engines do this, v6, v8, v10, v12 ect. It might not even have to be as long as the blade turbine
This does not work. You aren't increasing the efficiency that way. The problem with that solution is that by adding more disks the efficiency stays the same, but the throughput increases (as you add more space to fill with steam). To increase the efficiency of these turbines, you need to increase the RPM, which is not done by adding more disks.
@@osteogenesisdev5268 I think what he meant is to have much smaller disks so that the high RPM's required for efficiency wont be an issue. Smaller disks mean lower structural stresses on the disks and lower mach numbers at the tips; however, smaller disks also means lower throughput so that's why he's suggesting adding more disks in parallel to increase to throughput.
@@jonathanmgoodman I don't think that benefits efficiency either. It might improve the efficiency with regards to speed, but you have more material, friction, etc. to deal with. Keep in mind that reducing the diameter has a quadratic relation to the surface of the disk. So say you halve the diameter, you need at least 4 times the disks to make up for that. Meanwhile the speed at the edge of the wheels scale linearly with the diameter, so it's quite a bad deal. As a result of that, I think it's simply not really worth it. In the end, the currently used turbines are already 90+%, so at the absolute best you could get 10% more efficiency, but you already need impossible materials to simply match the current turbines.
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!
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.
The materials exist to make this work with a six inch discs pump, unfortunately the efficiency with 35.000 RPM polymer/titanium, Kevlar, carbon fiber or ceramic/beryllium discs, will be far from 97%, and around 60-70%.
@Oog Oog It's a possibility, carbon fiber discs with graphene crowns might be an interesting option to get higher rpm from the turbine. But due to its high electrical conductivity and limited production for the moment, it might be difficult to manufacture these discs anywhere else than for prototypes. And more economically profitable uses of graphene (mainly electronics and high-end mechanics) could also limit its use for this purpose.
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 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.
This animation and explanation really deserves a lot of credit.... this is really good stuff, well done!
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 RUclipsr 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:

@@coolcat1530 what if we did have material that could handle that rpm tho, would it be outputting a lot of power?
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?
@@ricardobautista-garcia8492 he stated that himself in his autobiography. He was a boy in Lika (Croatia) and read a travel brochure about Niagara Falls which stated the flow rate and surmised that it was an untapped power potential.

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

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.

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.

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.
Exactly its so simple but so wisely put together that its just genius.
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 (or maybe 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 miracles for his co workers.
Way ahead of his day, died a pauper but left riches for all humanity. God Bless.

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

“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
The video animation designs produced are just superb. Thanks to the Lesics team.
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.

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.

@@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.

As I was taught at university it’s centripetal force acting towards the centre of the rotation but as the diameter decreases so the force therefore it is greatest at the maximum diameter!
Can we dam a shallow sea and build water based power plant?
Nobody gives a fuck about your credentials. Always remember this.
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.
more about da $$$ impossibility than physical metallurgy
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.
@@sycho-tech5104 or because we have to find solutions to this problem in some way
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
Tesla was just a poor business man. No Edison conspiracy necessary.

Hi, just a question. 0.4mm gap is mentioned, where did this dimension come from. The research I have seen indicates 0.5mm at low speeds up to 1mm over 40/45K RPM with anything under 0.5mm. .decreasing output. Cheers John
hello
When your boundry to overcome is no longer knowledge or technologie.
But the physical limits of matter.
i would argue that teslas efficiency number is correct, just because it cant reach that in practice doesnt change that is its theoretical efficiency, you just need a lighter yet still strong material to make the parts out of, which may be possible in a future alloy
Yes you're right! I hope we'll be able to achieve it in the future.
Probably something to do with carbon
We have some lighter and stronger alloys now
Yes.
The guy who made this video is a bit on the negative side.
I'm an inventor and I don't like to say that it can't be done but how can it be done and try it, see if it works.
And can't you make smaller ones and string the output together?
Can't you make room for expansion?
Can't you find ways to cool it? Use liquid nitrogen to cool it, or ammonia. Ammonia while heated up becomes cold.

Tesla was a genius. Probably one of the most underrated/unknown scientist in the general public compared to the impact of his inventions
@Imjust Observing Tesla wasn't the brilliant genius people make him out to be. If this was such an amazing invention, why is it NOT in use anywhere in the US? This WOULD be the best generator for use in hydroelectric plants if it was truly as revolutionary as people claim it is. Please name one thing Tesla invented that has been used in mainstream production anywhere at anytime in history. You can't. None of his parents have ever had any practical or real world value. Nothing he invented remains revolutionary or has any lasting or profound effect on anything.
Tesla died broke and alone in a hotel room where he was a recluse who believed aliens beamed the ideas in to his head. He had embezzled money from his most wealthy benefactor, diverting funds to other projects which is why he wound up in this position.

@@alagui7894 One look at the wikipedia page for AC motor will tell you that Tesla wasn't the first by years. Don't get me wrong, he was a gifted inventor and decent engineer but BOY is he overrated in history.

Didn't feel getting that far into the specifics really mattered.
@Zakarii Tsuki ok, but if you need something and cant outsource it, you make it yourself.
What it seems unrealistic now as engineer could be kids play in the future. Tesla still ahead of our current time and we still has long way to go to catch the application of some of his concepts. Best regards and be safe
*This is apparently the algorithm's current favorite video*
😂😂😂
Funny enough I found this video by searching for it instead
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
Ey! You two above, stop! This is a place exclusively for clueless Nicola fanboys, keep your physics and common sense outta here, please...
@@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.
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.
His mistake was using metal. Marble wouldnt warp. It would only break if it was already cracked. Has anyone ever tried it?
@@wildfirekingdom9466 you may be right, but I wonder if marble could handle the G forces of that high of RPM's? A marble disk might explode?
@@sarakajira solid marble shouldnt have a problem. It’s very dense
@@wildfirekingdom9466 there are a hand full of other more viable options than using marble. thank god we dont live in the stone age. Modern alloy, ceramics and composites provide us ample opportunity to fab discs for steam duty like this at scale.
Amazing Sharing My friend! Have a Great Day ❤👍👍
There's genius in Tesla - but there's some genius in such a good demonstration in this video. Hats off to the authors and illustrators.
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!
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.
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.
You had me at “let’s start a design journey”. That’s when I hit full screen and laid back.
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.
Poor Nikola, he was born a few centuries ahead of time. He’s one of the most misunderstood geniuses
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.
@@CastleKnight7 go outside.
A few centuries ahead of his time?
Even in his time he was not a genius. If you put him into modern times, he would barely be qualified as "educated".
@@Diviance The reason that the lights are on and the AC motors which drive the world you live in are all his inventions.
People don't get smarter with time like you think they do, and advancement is both subjective and not linear.
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.
sadly efficiency is not as profitable. :( RiP tesla!
@@Maradnus that's what fins on a turbine are for, to make this exact system more efficient.
It is not underused. It just does not work well under load.
The genius of Nicola Tesla is indescribable!!! A man well ahead of his time. Just imagine if this man was here today and have available to him today's materials and technology. Imagine Tesla working together side by side with Musk. What a wonderful world it would be.
Musk is nothing like Nicola Tesla.
@@bender9000 yep, Musk is much more like Edison...
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
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.

Why did I never heard of this guy at school? I'm 60+. the only ones were Einstein, lot about him, and Edison. Even in today's media and schools nothing about him. His name only came famous by Elon Musk and his electric cars (Tesla). But from what I have read until now, he was the genius.
The Problem is, his ideas did not fit the world's consumption based model. Anything that can not be sold is discarded or hidden from us until they find a way to sell it to us. We are lucky that Solar energy, Oxygen and Water (which we as a species can not live without) are still free and in our grasps (most countries at least). but future generations will pay for it because those organizations that are supposed to stop pollution will make sure of that (by not doing crap against pollution)
Tesla's system is running, they just charge us for free energy. Tesla's towers are everywhere, weather towers, water towers and more.
@@mb59621 yes Mike and Phytagoras...and others sure.
Because the US government/military shut him down because of his haarp technology
You've heard of Edison because he invented the corporate laboratory: success doesn't get the actual inventor as much, but failure doesn't cost them as much either, so it makes innovation-based businesses practical as an ongoing concern. Edison did actually invent some other stuff, but corporate labs are the really _important_ bit.
As for Einstein, his theories effectively disproved some of how Tesla thought things worked- both of them thought quantum mechanics was bunk, but Einstein proved it by trying to disprove it, while Tesla just rejected it. Further, the stuff towards the end of his life didn't pan out, whether his death rays (mercury was involved in some, and unavoidable the usage would have been a disaster to the surrounding area), his wireless power distribution (there was no way to charge for it, and so no way to support it- further, he was aiming for _worldwide_ distribution, which effectively would require a worldwide empire to governmentally fund it), and likely various other things that I'm not thinking of. Finally, while he had a strong showman streak, he also tended to be secretive in some aspects, which resulted in some misconceptions about him even from his fans.
If stuff was taught this well in my FINNISH 🇫🇮 high school and college, I would have finished with having chosen all the physics classes
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.
Can we dam a shallow sea and build water based power plant?
You know you are onto something interesting when you build something and it OVER performs... It gets TOO fast or TOO strong. When its the material strength of the hardened steel that is holding it back. At that point, whatever it is; can be counted as an engineering marvel.
@I love you but For overperforming he meant that it was so powerful it didn't even work. It has not to do with expectations but with actual results: Tesla's expectations, as a scientist, was to build something that worked. He did, but worked too much haha
Engineering is the process of using technology to create the possible. If you come up with something brilliant but it doesn't work it is an engineering failure.
@@kennethfharkin It actually works though. Certainly it's not about practically using the turbine, but reaching that incredibly high speed. The turbine reaches it, and then starts to break, not allowing it to be used as a turbine.
@@TheTechmaster1999 Lowering the RPM lowers the efficiency making the design less efficient than a traditional turbine so... not really a solution. If something has to destroy itself at the point where it becomes efficient it really isn't efficient.
@@samueleproiettimicozzi8134 "It works" isn't exactly accurate. The theory is proven to be sound with efficiency increasing as predicted at higher speeds but the theory falls apart in execution. Tesla's turbine almost certainly never reached the optimal speed and would have destroyed itself well before nearing it. As an engineer myself I refuse to call anything an "engineering marvel" which flat out does not work and this thing doesn't if you are trying to use it as it was intended.
Now it functions to some degree as a pump depending on the application but I doubt we will ever seen a Tesla turbine operate as people imagine at anywhere near projected efficiency given the material and manufacturing limitations likely to be present for at least another hundred years and if we ever overcome those limitations a more suitable solution will have already be developed.
Instead of making them wider, just add more discs sideways. Car engines do this, v6, v8, v10, v12 ect. It might not even have to be as long as the blade turbine
This does not work. You aren't increasing the efficiency that way. The problem with that solution is that by adding more disks the efficiency stays the same, but the throughput increases (as you add more space to fill with steam). To increase the efficiency of these turbines, you need to increase the RPM, which is not done by adding more disks.
@@osteogenesisdev5268 I think what he meant is to have much smaller disks so that the high RPM's required for efficiency wont be an issue. Smaller disks mean lower structural stresses on the disks and lower mach numbers at the tips; however, smaller disks also means lower throughput so that's why he's suggesting adding more disks in parallel to increase to throughput.
@@jonathanmgoodman I don't think that benefits efficiency either. It might improve the efficiency with regards to speed, but you have more material, friction, etc. to deal with. Keep in mind that reducing the diameter has a quadratic relation to the surface of the disk. So say you halve the diameter, you need at least 4 times the disks to make up for that. Meanwhile the speed at the edge of the wheels scale linearly with the diameter, so it's quite a bad deal.
As a result of that, I think it's simply not really worth it. In the end, the currently used turbines are already 90+%, so at the absolute best you could get 10% more efficiency, but you already need impossible materials to simply match the current turbines.
@@osteogenesisdev5268 you cant say it doesn’t work without trying it..😜😜😜

But due to its high electrical conductivity and limited production for the moment, it might be difficult to manufacture these discs anywhere else than for prototypes. And more economically profitable uses of graphene (mainly electronics and high-end mechanics) could also limit its use for this purpose.
