Tesla Turbine | The interesting physics behind it
Vložit
- čas přidán 2. 06. 2021
- The maverick engineer Nikola Tesla made his contribution in the mechanical engineering field too. Look at one of his favorite inventions - a bladeless turbine, or Tesla Turbine. The Tesla turbine had a simple, unique design, yet it was able to beat the efficiency levels of steam turbines at that time. Normal turbines are complex in design, with blades of complicated geometry and stator parts. Nikola Tesla once said the Tesla turbine is his favorite invention and he even claimed an efficiency level of 97% for this turbine. Let’s start a design journey to understand this interesting piece of technology, and towards the end we will also verify Tesla’s efficiency claim.

Man really said
"I'm limited by the technology of my time"
Technology is just knowledge.
That's Howard Stark!
I want to make a time machine but ""I'm limited by the technology of my time"
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.
@@coolcat1530 what if we did have material that could handle that rpm tho, would it be outputting a lot of power?
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 CZcamsr exposed.
Being a civil engineer who has studied fluid mechanics for 3 semester I am totally flabbergatsed by Tesla. This is mind blowing..
Tesla was robbed by anyone and everyone he came in contact with, incredible man, out of this world.
Heh... look at all his stuff regarding vibration. Electrical guy, sure... but he practically invented vibration analysis...

Edison after seeing this: Edison's turbine
Ill give you a gazillion dollars for it
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%! When used in a small form factor, in combination with a simple but specific generator geometry that uses non-ferrous magnets, this technology is absolutely perfect for every home to generate all the energy it would ever need using warm water.

@@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.

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.
the simplicity of the design just makes it cooler
"Simplicity is the ultimate sophistication."
-Leonardo Davinci.
More simple something is. The more design time spent
The design concept is simple but the forces and Physics utilized are way past modern steam turbines
KISS principle
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
idk why this was recommended to me, but this is quite interesting.
Same here. Subbed anyhow. Lol
Same here! Thats a really good invention but humans cant handle it 😂😂
it was Tesla himself,blessing you with a glimpse into his world lol.jokes aside,this guy needs way more respect paid to him than he has had.
Same and subbed, yee yee
Indeed. Now i can make my turbine.
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
The video animation designs produced are just superb. Thanks to the Lesics team.
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.

Some concrete pumps use Tesla discs because they can flow chunky materials, as long as a certain size of grain is not exceeded.
The grain thickness can't go past the thickness of the space between the disks

Don't they use rotary pumps for that?
@@the_flying_fox yeah I'm pretty sure.. you can't even find T pumps on the used market, I dont know where a concrete company would get them
@@the_flying_fox Yes, many concrete pumps are rotary.
I think Tesla's idea was that given sufficient materials capable of taking such forces it could achieve 97% efficiency.

Can we dam a shallow sea and build water based power plant?
My thoughts as well…..
Engineering mostly about doing the thing with the materials you have, not the materials you want.
He never produced anything that worked.......
The basic principle for the Tesla Turbine is well presented, but there are considerable number of secondary, as the speed ratio between the steam and the disks, and tertiary dynamics such as the turbulence in the boundary layer (which is the transfer energy vector ) when the relative speed between the fluid and the disk is changing are not noted at all, and these by themselves affect hugely the efficiency of the turbine. Also note these "bumps" in the shaft, these are fluid bearings (!!!). For those interested more, highly recommending "A new dimension for Power" book that represents some research and most of Tesla documented notes on the turbine.
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

@justan idiot your nick suit you
@@vasiliansotirov6976 Because it’s not the output that is the issue. It is the speed of the disc to achieve maximum efficiency.
“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
a source of energy - they are warm air, which is transformed into rotational motion in a concentric vortex.
The basis is a disk that rotates between the covers, creating a large vacuum in the center.
There is a hole in the top cover (it is also in the center of the disk to use both sides of the disk) above the hole there is a dome, in the dome on the edges there are holes through which warm air enters.
A vortex is formed in the dome, which rotates a small (compared to the disk) turbine - the turbine is attached in the center of the disk.
The drop in temperature is so severe that the bearings freeze (which is a big problem).
When accelerating, there will be a howling loud sound, you need to accelerate even more to pass this threshold, then the vortex will push the turbine and the disk itself.
This is a source of energy. Thank you...
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!

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 .

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.

@@user-fc9kq5vz4g It was full of physics. If you think physics is fancy math equations peppered with arrogance than you had a very bad teacher. :P
Physics is understanding nature. It does not matter, how you do that. The animations visualized very well the boundary layer concept. Anyway, I have never ever seen a really decent model made for tesla turbines. There are unsolvable theoretical equations and semi empirical approximations.
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.
i would introduce him to a magic substance called weed,he probably tried it anyways,his best friend was Twain,and he loved,as he called it "hasheesh" which was a very concentrated marijuana thingy....
Agreed
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.
@@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 CZcams 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.
So so true buddy...!!!
Super excited to see the explanation of the Teslar turbine very interesting to me. 👍
I love how Nikola Tesla’s Inventions can all be summed up as “ it works to good to work practically”
If it was practical to apply that that would make it good, otherwise no good. That is the whole point. Many inventions are out there that are great theoretically, but without the materiel science to bring it to life, none of these inventions are practical. My friend with Phd in Physics tells me this.
@@sevencostanza3931 Yeah but Tesla sort of an bodies that way of thinking
@@sevencostanza3931 the hilarious thing is that all of teslas claims have been-or are in process of being-proven. The dude was tony starks dad, ahead of his time, been dead for years and we are still getting schooled by him. You’re on a tesla device just by sending a message.
@@sevencostanza3931 "My friend with Phd in Physics tells me this." yea and you forgot to mention that noone knows him contrary to the Tesla...
Tesla work revolutionized the world, the guy was building RC models in XIX century and there was no material for this type of job.
Similar story with Wright brothers if everyone would wait for proper parts and proper material we would not be able to do powered flight to this day.
No to mention that from the video its clear that Tesla designs are used to this day and modern tech depends on his inventions more now that it was during his life...
@@Bialy_1 As stated in the video, many of Tesla's inventions were never developed & cannot be even to day cause of material science. There NOT practical. The main Tesla invention-AC induction motor & A/C power use---was the best invention & of course practical.
Damn! Serbian people must be really proud of Tesla🤘Greeting from Scandinavia ❤️
Yes, after his death they were proud.
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.
Thank you very much for this clarification ❤️❤️❤️
Its amazing that we are still trying to unlock the potential of someone who lived in the 1800's.
That almost proves that after 200 years the designs were never viable even with all those people trying to make it work.
@@Ureallydontknow
1) Not 200 years. Tesla as 1856-1943.
2) Many of Tesla's designs were viable. This one ... somewhat (as stated in video). However, Tesla had huge impact on workable designs still in use...for example with AC power and motors.
3) One of the remarkable aspects of Tesla's career was that he did much of the creative work solo.....in his case it was remarkably less a case of 'all those people trying to make it work'.
reading your comment, I remember the great pyramid of egypt. until now we can't actually point out how they exactly did it
@@Ureallydontknow He Was Smart Enough To Compartmentalize.
@@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.
That was the best simple explanation of a tesla turbine that I have seen, I'm glad you also explored the engineering challenges. Thanks for the video!
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.
believe me, not this one would have done it sooner or later
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.

OMG !!! THE ANIMATION !! THE PHYSICS!! ITS JUST PERFECTTTTTTTTTTTT!!!!!!!!! RESPECT !! GREAT JOB !!😍👏👏👏👏👏👏👏 that's it I'm subscribing
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

That boundary layer highly depends on the fluid being used. Tesla's design was based on water. There are many fluids that have very low cohesion like castor oil, but water has a unique property of high cohesion. Surely PTFE should suck for boundary layer. So, adhesion levels would be between the material of the disk and the fluid. Some kind of anodic fluid to metal substrate might be best, but wear out. It would be interesting to see more videos about titanium disks with some kind of cobalt substrate and cupric fluid for more magnetic type cohesion and adhesion. Anyway, the design is so simple, but has potential that people just left on the design floor. Crazy.
I think the newest members of the material world might play in there somewhere... "tantalum carbide and hafnium". But I really like your answer. I'd say time to bring in the science team and see if a better, more stronger carbiding or carburizing of these new materials is capable...
I'm just a software engineer so excuse my ignorance, but could you make disks that can sustain the centrifugal force out of graphene (once graphene is mass produced).
I think a lot of comments are misinterpreting this video. The entire video is to illustrate why the Tesla turbine DOESNT work even though it seems like it should be amazing.
The other thing that people seem to be ignoring is that modern steam turbines that don't use a Tesla turbine are capable of 90% efficiency. To achieve Tesla's 97% claim can't be done because of the restrictions on modern day material properties.
@@scottr397 well claim vs. speculation is always good to investigate if it sounds too good to be true. Exploring stuff like this interesting to everyone that responds in a constructive way. Even if the constructor is to provide/prove negative results
No. The principle applies to fluids and solids. Which fluids and solids are used would be a matter of choice.
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.

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
What a great video!!! Thank you!!
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.
So cool. I've never looked into this before. Pretty amazing that it's just flat discs.
I worked on and ran "dry-cleaning " machines back in the day. Big machines! Spencer 200 could take 200 pairs of heavy-duty cover-alls in a single wash! Wash them and dry them in one cycle or 1.5hrs. The pumps on that machine had a single disk with just a raised fin just 5mm (1/8th) on the outer edge and just 1mm (1/16th)to the inner edge, with 4 fins on the disk. That thing could pump 300gal/min !! (5gal a second!) Had to keep the fins clear of build-up on the low-pressure side,, a fine sticky compound. Had to keep an eye on the pressure gauge and if it dropped to low then we pull it apart and clean it. Only would take 10 minutes,, no sweat,, I think the machine was made in Germany.
wow excellent video in every way. informative, straight to the point, no extraneous nonsense, doesn't cater to the lowest common denominator. have a sub.
When your boundry to overcome is no longer knowledge or technologie.
But the physical limits of matter.
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.
Wow... amazing...i love viscous forces...
This is pretty neat. Probably not great for power generation but perhaps a large water battery. You pump water up during peak times and use the pump to generate power at night
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.

Your caption led me to believe there was some mysterious hidden knowledge about the physics of Tesla's turbine but this is more or less regurgitating published information that Tesla fanatics have been sharing and swapping with one another and have been experimenting with for decades. I do want to compliment you on your article and your explanation and illustrations. Twenty years ago your video here would have advanced my understanding a lot sooner because even if I understand it now, it was slow to get into my sometimes thick skull. Great video. I don't think we fully realized Tesla's true genius.
Thank you for such educational cartoned video lesson
Tesla has got to have been from another planet. That’s the only solution to one person being so ahead of his time with absolutely everything he touched.
Think along the lines of Quantum Science
Also explains why the government seized everything the man invented and kept secret in his safe the day he died. They still haven't released the documents or even General descriptions of the inventions he had in there
He was a real Inventor, probably the last one.
@Paul Robert oh. Silly me. Thanks for your well informed and eloquent rebuttal.
This looks like a great starting point for some Sci-Fi where we have a material strong enough for Mach 13 spin rates and can get incredible efficiencies from this turbine.
Right
Look into the speeds jet engine operate at. Spinning a simple disk at a high rpm, by comparison, is easy.
I refuse to believe this as long as Tesla gets even one penny of Government funding.
What interesting plot can you make from that starting point?
@@justingrey6008 Yes, but you forget to take in to account what he said in the video. In order to use these efficiently, the discs would need to be 3 meters, jet engine doesn't use a 3 meter disc to operate, they use fans and they usually spin at around 3k rpm, not 50k
I thought by changing between the plates would work. But on second thought I think by damping the exhaust's, the one could control the heat in the boiler and control the speed of the turbine.
This is a very well made explanation.

I am a degree plus qualified mechanical design engineer and this description of the effects is far and away the best I have ever heard! I have subscribed and I’m looking forward to seeing many more of your videos. The only thing I would say is that whilst most people understand the idea of centrifugal force it doesn’t exist! 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!
