  • Published on Jun 2, 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.

    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.

      @Zach Ruch The bladed turbine has had trillions of dollars thrown at it in R&D that continues today. All of that is to solve problems in design and materials. How much has been thrown at any of Tesla's projects? Outside of the university projects given to grad students as a thesis publication for graduation purposes and the "off the public" books of government experiment. (i am not a conspiracy theorist. let's face it the Manhaton Project is a prime example of government conpartmental experinment). How much do you suppose? Some of Nikola Tesla's works could make a lot of the top industrialists very poor and make the WEF irrelevant. One more question. Have you ever wondered why man was using horse and buggy up unitl the 19th century and gas to light up a room until the early 20th? If you go by the Bible Time line that would be roughly 4000 years of walking, pack animal, and horse. If you go by the Evolution Time Line that would be in the millions of years before any improvement. What was the catalyst that accelerated all of this industrial developement? Why do we have so many videos that say that Tesla's works are an engineering impossiblity?

    Wouldn't the next upgrade to the system naturally involve multiple smaller tesla turbines since the size of the discs is the limiting factor? Seems weird that it would go through such an evolutionary path but the question of micro scaling wouldn't be brought up. You could then scale the system up to handle the same amount of input and you would dramatically improve longevity as well by having less strain on the system. We also have materials such as microfiber nanotubes among others with incredible properties.

    • Daniel Hani

      The efficiency of tesla's invention is based on how much energy you get from the flow. This energy is a centripetal force exerted onto the disk and is a function of the drag on the disk, this drag is affected by the surface area. Minimizing the size reduces the area which reduces drag thus reduces the force and efficiency. The problem with the disks being too big for that speed is caused by an engineering concept called "moment" not the time concept but rather the behavior that raise the magnitude of forces. To understand moment in a simple way try opening the door by pushing near the handle it's easy because it is away from the hinges of the door that are on the other side. But try pushing the door open halfway through the door it gets harder and harder as you get closer to the hinge which would likely lead you to exert all your strength and barely make the door move this is because you are getting closer to the axis of rotation and the weight of the door cause a frictional force at the hinge which your body can't win against unless your force is increased. Moment is force x distance from the axis of rotation. More distance = more moment which means less of need to exert more force. But with this concept when it comes to going 50,000 rpm on 3 meter disks, at the edge of the disk 3 meters away from the axis of rotation you have more moment so much more that the material in fact every material will fail because we don't have knowledge of any material that can withstand that much exerted force. The only thing we know that's large and can spin fast is neutron stars that spin at 9% the speed of light but they have so much mass and gravity holding them in place that a tea spoon is literally a compressed earth.

    The 220φ engine accelerates the ions confined in a loop to moderate the relatarvistic speeds, and then varies their velocity to make slight changes to their mass. The 221φ engine then moves ions back and forth to produce ions, thus traveling in a vacuum line, so please use cruise control on the interstate.
    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.

    Thanks for another excellent video clearly explained and illustrated with great graphics.
    Perhaps Tesla's turbine could be modified to have max efficiency at much lower RPM levels if
    -the input pressure is increased e.g. by hydraulic head (gravity) and a tapered inlet
    -the surfaces of the disks were textured or even e.g. radially ribbed like millstones.

    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!

    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.

    Very good explanation, clear and on the point!
    Not all things are meant to be enlarged, some are, precisely, very efficient the size they are or even smaller. Several small tesla turbines connected to a differential, then a gearbox and so on you could harness a lot of power from several small turbines, and equal their overall output. If you make it a closed circulation system, try additives and options besides water, maybe efficiency can increase. There are different materials nowadays that can withstand incredible forces. I mean, steam turbines have received a lot of research, A LOT, it's only normal their efficiency is so high. Tesla turbines have a lot of potential!

    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.

    The interaction between a jet of steam and the buckets (vanes) of a modern impulse turbine is pretty close to an elastic collision, while the interaction between a jet of steam and a stack of flat discs is an inelastic collision.
    To put it another way, in a Tesla turbine, we are trying to achieve maximum friction, while in a conventional turbine we are trying to minimize it. This is why I have trouble believing Tesla's efficiency claims.

      @Jacqueline Brunder Time does exist, it's intrinsically linked to space. Spacetime is already experimentally tested and holds up to the greatest of scrutiny we've managed to date. Now gravity on the other hand, gravity doesn't exist. Something Einstein and Newton disagreed on, obviously, but Einstein proved him wrong almost immediately. Anything falling towards a given mass has an inertial frame of reference. Spacetime curves around mass. Gravity isn't real.

      @Blue Bandit Good point! Because they arent really inventions as they dont work (yet). Can easily think of a couple. But the thread also gives you a few examples. Like a space-elevator. Traveling to space is extremely costly! Spaceelevators would significantly decrease the cost of transporting stuff to space, however - We don't have materials that are capable to withstand the stress involved in such high elevators.
      But my point is, that it can be said about many things, if i only imagine materials with the properties I need for my invention.

      @Proton Neutron yeah on a clutch or an automatic transmission both of which rely on clamping pressure more than friction.
      In torque converters its the fluid being scooped up by the blades and "thrown" into opposing blades to "catch" the fluid that transmits power friction in a torque converter LOWERS its ability to transmit force.
      Also inertia is not friction. friction is to materials asperities interacting

    • Proton Neutron
      Proton Neutron 3 months ago

      @Adam Perry right the interaction of matter to matter causes motion. Another word for "friction" in physics is imparting inertia. Thanks for playing

    • Adam Perry
      Adam Perry 3 months ago

      @Proton Neutron no it doesn’t a torque converter functions as a conventional turbine. Your motor turns an turbine which propels fluid which hits a stator to redirects flow to an impeller, this fluid hitting the impeller blades is what transfers energy
      Your thinking of a either a clutch or a automatic transmission but they both have force applied to them to increase friction.

    • Adam Perry
      Adam Perry 3 months ago

      It’s because they are a novelty. The largest issue with Tesla turbines is that they generate an extremely small amount of torque. With the example they used as and industrial Tesla turbine it probably wouldn’t even be able to get up to the 50000 rpm range as it would t be able to overcome frictional losses.

    • KalasenZyphurus
      KalasenZyphurus 3 months ago

      A lot of Tesla's inventions are about maximizing for some attribute. Turbines are for turning linear fluid kinetic energy into torque. The fan blade design lets fluid flow past, and can't approach a theoretical 100% conversion. So he came up with a design that makes the fluid stop and leak out the sides perpendicular, converting all of that energy in principle. The faster the incoming stream, the faster the device rotates, and the more the fluid has to slow down before exiting the device.
      So basically Tesla saw people inventing "good-enough" solutions that could never maximize the desired result. He invented things that could get infinitely close to the best possible result. But the thing about infinites is that if you expand one variable in a system infinitely, you also tend to expand other variables infinitely. In this case, infinitely close to 100% efficiency also means infinite fluid speed, infinite RPMs, and infinite disk/casing durability. If you pull it back to reasonable inputs, it turns out that the "good-enoughs" that can never reach the theoretical maximum even with infinite input, beat the max-potential device. At least until we invent ways to increase the reasonable limit of the inputs.

    Making this more efficient is easy. Have scoops direct flow inwards at a diagonal angle. Have a swirl style channel and dimples and bumps on the plates. Have it exit at the center like normal. It now is trapped and producing viscous force throughout the swirl channels as fast as it can. Exiting with a good amount more force expended into the plates.

    I wonder how this would work with output potential at the lower speeds to keep the turbine in one piece until a load larger and larger load is applied and with the power output of the pump could be increased to manage the load until the demand is no longer needed, hence back off the turbine speed. I guess delta would have to come into play over power, delta being the time to get those higher rpms built and turning into mechanical energy. Guess I'm asking with so much potential sitting at any giving point how quickly can it be turned into a mechanical energy for larger loads like a end load? any quicker or efficient than steam turbine in the same event?

    My interests are not in a large size, I want to produce just enough to keep one resident going. I’m looking at the hydro concept. I like the encased example. First what if you add raised swirls on a disk and lit water come through an upper port as the Tesla example showed. Now if you were to force water through it in an controlled manner turning a small turbine with a shaft protruding out one side to turn a pump to return the use water back to its original point.
    This is what I’m thinking in my case . I own my own home, what if I was able to build a way to catch rain water from my houses roof. Then pump this water through an opening in a small turbine example given to us in this video. Now as the water flows through this system provide a reservoir to catch the water passing through the system 1. When the wheel turns you produce electricity as the water passes through the system . 2. When the turbine turns either as the wheel in the turbine turns use it as the the pump. Or you could the power it produces to move the stores back to its original starting point. Which I was thinking above the turbine you made. 3. I’ve been studying on how to make a homemade generator, I even have a Honeywell Redi- Line motor generator on hand to start the process. You could potentially have an in endless power source. Thank for getting the wheels in my mind going.

      How about this idea... you have a rainwater collection tarp (think an inverted pyramid that gravity pulls water to the exit at the bottom)
      You could have this water uphill on your property or elevate it, to use gravity for your benefit. Have the rain collected water go to a cistern size of your choosing (which would be filtered to your liking. I prefer reverse osmosis deionized filters, if I was building a home, they run about 2k)
      If you have the extra water from your cistern overflow into the entrance of your generator and irrigation system, now your free rain water turns into plants, and energy from your water wheel turbine!
      Some states have laws against rainwater collecting, and have certain stipulations about where you can direct rivet and stream water
      A few acres with a stream through it is a GREAT buy. The river is obviously invaluable, possibly fish, frogs, bugs, deer, rabbits. Potential kinetic energy as well
      So yeah man those are my thoughts on the whole deal
      Also consider what safety measures you would put in, in case of a flood

      ​@Tim Holmes
      I think the obvious problem would be how do you seal the vacuum in and still be able to move the fluid over the discs to generate angular momentum. The presence of the fluid itself alone nulifies the idea of a vacuum, as the fluid needs to have an intake and an outlet to generate spin.
      I was thinking about the possibility of designing the disc with small pins running across the discs at intervals holding the frame together to counter the effect of the centrifugal force causing the discs to warp. I wonder if this would adversely impact the level of wear on the assembly and severely impact the durability and practicality of the turbine.

    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.

      @Brian P Comparatively, to what we have?... its surprisingly little actually. Maybe not so surprising when you think of it like a puzzle with too many pieces. Eventually you will get most of the pieces in the right spot. Eventually.
      Most of our DNA is useless as it continually builds off the past. Well,.. I say useless... but who knows when one of those little switches will flip.
      Also... minor correction.... DNA is FAR from perfect. It's so flawed, that it hurts. But thats besides the point,... your assertion that it would need intelligent design to reach the point humans are at requires evidence. It's simply an unfounded statement. As it stands, there is more standing evidence to suggest that it CAN reach such a point without intelligent design, as opposed to the complete lack of evidence to suggest that it can't.
      That said... I don't think either of us would disagree that any concept of God, would simply be able to poof this all in. It stands to reason that an orderly intelligent design could certainly do it, and even do it better! But said God would still require more than baseless conjecture to be considered a possibility.
      "doesn’t address how these basic life forms expand their DNA over time to evolve into larger more complex creatures and certainly not in an ordered way"
      Actually it kind of does, life and death, creation, age and change happens on every level of existence for organisms.
      ... and you are right that it doesn't do it in an ordered way. It doesnt have to. Life, and essentially your DNA, has time,... its you that doesnt. There is nothing to assert that it would have to do any of what it does in an ordering fashion either. I would say it helps explain why it took so dang long to get where we are in the first place.
      Another correction "not biologically advantageous to carry around organs that are partially evolved that do not function yet"
      in some cases organisms do, you even have some things in your own body that will cause you more harm, and little to no good... were you not aware of this?
      in others, they function just fine in their lesser versions. Organisms evolve based on what works, and over time they change(but not necessarily improve)... those that didnt, die.
      "Thus we have an infinite cause, the source of the first motion in the universe, the prime mover, ie a God."
      Thats just one huge fallacy statement. One, you jumped from point a, to point z without a real connection- its just one big leap of logic. You have to assume you already have all the pieces and understand everything involved to even make the case. Its what all religious goons eventually fall back on... "BECAUSE GOD!" ... its stupid and lacks any real thought.
      Your use of a lack of information to confirm God in the positive, is worse than the lack of reason people give for claiming he doesnt exist. Appealing to ignorance is one of the worse arguments you can make.
      Besides,... we do know where our intelligence comes from. And we have a fair grasp on why it developed to that point.
      What we don't have, are humans capable of grasping just how lucky they are and accepting it.
      We have people asking, "What are the chances? There is no way"
      But we do not have anyone saying "No matter who it was going to be, they would end up asking the same thing" And why is that?
      It didnt have to be you. Stop staring life in the ass and making up narratives for how it came about. Try to actually understand it, rather than arbitrarily making crap up to believe.

    • Mr. Meow
      Mr. Meow 8 months ago

      @Daniel Wilkinson "a fool says in his heart there is no God."
      while flawed, its still far better than the fool who says in his heart there is a God without ever having set on a path to find God and confirm it.
      Without evidence and reason, to claim an answer to the complete unknown is the height of folly. Every religious argument for God, eventually falls back on nothing but pure belief.
      To answer in its negative, when no evidence suggest it in the positive, is still folly as a lack of evidence is not proof of its non-existance. But at least it lacks delusion.
      Also... please try to understand the topic material you bring up BEFORE attempting to use it as some kind of foundation for anything. You clearly don't understand DNA or evolution.
      It would also help to understand what science actually is, and that a process to discover truth cannot be compared to a cult that asserts truth arbitrarily(and thus cannot be seen as anything other than being made up... as in, untruthful or at the very least dishonestly given without being truly known and discovered). You don't have the points you think you do. This is the problem with you idiots. Science isn't just out to destroy your religion, its not on some scale where either science is true, or your religion is true... it could care less about it. It's just that your religion doesn't follow any logical form of thinking. Thus people start seeing how stupid it really is.

    • Brian P
      Brian P 9 months ago

      @Matt Brown cool article. However just because we were able to produce the basic RNA which presumably would be the basis for the first life forms it still doesn’t address how these basic life forms expand their DNA over time to evolve into larger more complex creatures and certainly not in an ordered way. Let’s consider organs for example, how many different parts of our DNA are involved in the creation of say the heart? The heart is a very complex muscle/organ and if even one part of it is not properly formed or is absent then the whole organ fails and the heart being critical in most creatures means the creature dies not allowing the progress of the random evolution to continue. Even if it was a system that wasn’t strictly necessary for that creature at that point in its evolution for its survival It does not seem logical or biologically advantageous to carry around organs that are partially evolved that do not function yet. Thus it would seem that while the basic RNA can be created via the correct conditions and elements, the expansion of that into some thing as perfect as the DNA required to produce a functioning complex being such as a human or even an animal requires atleast some form of ordered guidance which speaks to intelligent design. Where then did the intelligence come from? Our universe, built on the principle of cause and effect, tells us that there must have been an initial cause to give the universe motion and it had to come from outside our material universe. Thus we have an infinite cause, the source of the first motion in the universe, the prime mover, ie a God.

    the problem are the high rpm🤷‍♀️at 40-50k rpm everything goes bad, bearings, discs and so on...sadly🤷‍♀️

    Hasn't there been some advances in bearings over the years perhaps even replace the bearings with magnetic type bearings surely there must be a way to get this to work as Tesla intent.

      Bearings aren't the issue, the size of the discs are. Under the speeds needed to achieve the high effeciency levels, things literally start to fly apart because material science hasn't quite come up with something to withstand those forces.

    If only Tesla's technology took over the world instead.
    Can this be done with water flowing into canals? since everywhere has water canals from their homes pushing water back into reservoirs/treatment plants.

    Doesn't the fluid flow need to be fast enough to power the engine? in order to accelerate the engine, the fluid needs to have a speed higher than the linear speed of the disk at where they contact each other right? Is this speed usually achievable and how?

  • RSGTomcat
    RSGTomcat 9 months ago +160

    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.

      Increase the viscosity of the fluid or decrease the temperature of the disks

      Unfortunately no. Flywheels have been tried, but you run into a few significant issues. The high speed discs cause rotational / angular momentum and will counteract turning forces. The speed of the discs is hard to capture and transfer into power for the vehicle - imagine redlining a car and then shifting a manual transmission without being able to adjust the incoming rotation speed of the engine. Finally, in an accident, the energy needs to go somewhere, those discs are very deadly with all that stored energy. Finally, the waste of energy to spin up and not use the power - say stuck in traffic or making frequent stops to run errands, means that the energy is lost or wasted.

    TLDR: Tesla, back in those days, created a machine so powerful, even today we don't have materials nor physical capability to use his invention at full power.
    His invention (BACK THEN) is literally too powerful for us (RIGHT NOW) to contain its full power.

    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.

      @Wildfire Kingdom 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.

      @Wildfire Kingdom 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?

      His mistake was using metal. Marble wouldnt warp. It would only break if it was already cracked. Has anyone ever tried it?

    wouldnt the disk size be able to be reduced by adding more disks and increasing pressure? and wouldn't increasing the width of the intake nozzle to cover more disks work to help it too?

    • Aiden Aune
      Aiden Aune 5 months ago

      @hanelyp1 pressure turns into velocity when it meets a lower pressure system, that is why a hose sprays when you cover part of the hole. the turbine would be a lower pressure due to its higher volume relative to intake.
      increasing the width of the intake would help spread out that pressure over a greater area, reducing the pressure at the opening (with the pressure being due to it backlogging as friction reduces its spread to other locations), and thus increasing speed.
      increasing the disks would counteract the reduced area of the smaller disks too, increasing the effect to a similar point as the bigger one.

    • hanelyp1

      This is not a pressure driven turbine, but velocity driven. The inlet nozzle needs to convert pressure into velocity.

    How does the working fluid slow down and go into progressively smaller volumes (same gap between rotors, smaller diameter as you move toward exhaust.) without pressure going UP?
