Tesla Turbine | The interesting physics behind it
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.

    *_Think this guy is smartest? Seeing as the oldest computer is over 2200 years old, which came nearly 2100 years before Nicola Tesla was even born it leads me to believe there were way more intelligent people in the world, perhaps constrained to the technology available during their time period._*

    Nothing is said about loads... I don't think it would achieve the efficiency and speed of 10000 rpm with a load of significant size like a power generator.


    ⭐If we connect this small box with our home water pump then that pump serves dual purpose of filing our water tanks with ground water& providing free electricity. Maybe this machine is great for home energy production & not commercial electricity production.

    why would you need a turbine 3 meters in diameter. What about a turbine less than half a meter in diameter with the same torque. But I guess harnessing 50k to 100k rpms from turbine to generator would be difcult because turning a generator at such high rpms would be ????? I don't know but something small with a reduction of rpms could produce a hell of a lot torque. Power house in a small package.

    I wonder if the blades were made thinner at the edge could alleviate the problems. Thinning the edges would allow a greater area for the fluid to flow through thus reducing the drag effect.

    I'm no engineer but the tesla turbine sounds extremely inefficient. I would know if it was if you bothered to say how much power it takes to get the thing running in the first place instead of focusing on what it can do during and after it has an unknown amount of power. Also if this thing is actually being used why not use a photo of a real one instead of a 3d model?

    🤣🤣🤣 Every piece of technology is thanks to Nicholas Tesla. But, school only teaches about Einstein and Thomas Edison who never invented anything

    • Jared Maddox
      Jared Maddox

      Edison did invent a few things, but his only deeply important one is the corporate laboratory, because it makes science & engineering more economically sustainable (he may have personally invented the record player and film projector, but both are antiquated, and would have been old versions anyways). As for Einstein, he was a scientist, while Tesla was more of an engineer- meaningfully different fields. Einstein earned his fame by devising formulas to predict observations (including quantum mechanics observations, though he was trying to _disprove it_ when he did so), while Tesla was _mostly_ focussed on applying existing knowledge in new ways. Hence Tesla invented the induction motor and an early version of the electric grid, while Einstein is distantly related to some particular aspects of modern electronics (the transistor is built off quantum mechanics). I think Einstein had something to do with improving the understanding of thermionic emissions (which were used in vacuum tubes) too, but I forget the details.

    Louie Macorncan

    To add stupid but wonder in dwelling in question, what happens if you wield the disk, as in making small piller inside the tiny gap? I mean if you think about it, to stop the warping for there have to be a support beam to hold the disk in place and yes I am aware of the disk losing some power of rpm. If we can wield it and not lose rpms and able keep the flow right then it would be the best energy conducting for little tiny gizmo would power probably 2 or 3 houses.

    so all we need is a 6 inch disk that can go 35,000 rpm. if only there was a round item sort of like a high speed saw bade that can spin very fast like a high speed cutting tool. all joking aside would a composite Kevlar/ceramic plate work

    Does this work in reverse? If you spin the flat plates does it generate thrust?

    • Raycar

      It can be a pump or compressor, yes It does not produce thrust it produces axial rotation, which, when combined with a generator produces continuous electricity. This video got alot of things wrong... if your really interested I'll post a link to a decent presentation of teslas work.

    The efficiency argument is specious. Friction inherently causes dissipation. It probably depends a lot on the load, but the video does not address that. While the Tesla turbine is an interesting concept, traditional axial turbines work well enough, so the world will stick with them. The are millions of interesting engineering concepts, but the only ones that count are the ones that work in practice.

    • Raycar

      Tesla's turbine definitely worked. There are many people still using them today. Dont believe everything you see on an animated video less than 10 minutes long.

    It's ingenious, but in spite all the Tesla-fanboism on display, the prizes in engineering should go to the solutions that can actually be built and work efficiently. The Tesla turbine is great in theory (with currently impossible material science), but in practice only of use in edge cases (like pumping viscous fluids, or fluids with large particulate matter). In a sense, the Tesla turbine is like the space elevator: the best solution to a problem, if it weren't for the fact that we have no idea how to come up with the materials required, or if that's even physically possible under conditions on Earth.

    Hmmm. If the RPM is the problem of material fatigue, simply, you can't make it efficient by inventing new material. Yeah, generators can be adjusted. But also the turbine. Here's a theory: - add to the shafts flywheels which has some sort of magnets in it - the flow valve for the turbine is regulated through the flywheel electromagnetic induction that regulates the valve - valve is an electromechanical component, meaning, the more flywheel spins or vice versa, opening or closing of the flow valve is regulated - flywheels add rotational energy, so the generators internal resistance under load is being mitigated - it's a pain to optimise it but it's palusible. - power of generators is closely proportional to the size and weight of the flywheel - 3 phase motor with 36 poles is more than enough for 3000 RPM - you can always make a shutoff by making the generator as a break for the flywheels. Thoughts?

    i can only assume that physics plays a part in this. there by, shrinking the radius of the disk will ultimately slow the recorded speed of the outside circumference of the disk. we should all know that the inside radius of a disk spins slower then the outside of the disk at the same point, if you understand the "point" i mean. a disk with a 6 inch radius will spin faster on the outer edge then a disk with a 3 inch diameter at the outer edge. also, surface tension plays a huge role in this. if you use a smooth disk, with low surface tension, the less the force the viscus fluid will have.
