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.

    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.

    When the pressure can give you more than 50k rpm but you only choose to receive less than 10k rpm, you are literally wasting the energy... which means that turbines nowadays are still very 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?

    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.

    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.

    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.

    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.

    It's possible now with finite element analysis. The disc's don't have to be uniform and can be wider toward the edges compressing the outward expansive force. It would be possible to cause the water to compress and heat itself up especially if tiny dimples are added to increase the surface area. At high speeds its really a fly wheel, a type of mechanical battery and the spinning itself would not be a turbine and could power another turbine while also regulating the current like a capacitor. If it were not constantly thought of as a turbine we'd make some progress. Mechanical batteries of similar design are used in power plants as backup storage where the residual rotational mass like a fly wheel becomes its own battery. To charge a flywheel battery while heating up the water to create steam via pressure could be used to as 2 sources of power that counter balance between the steam turbine and the flywheel and the turbine. The turbine can be paired with Tesla valves to work as pistons. The original electric street cars ran in mechanical batteries and were only burned after gm and rubber companies killed the electric street car and forced us for use disposables wasting 100 years of our time causing war after war, and destroying the planet. Elon musk bought Tesla sued the original founders to force them to call him a founder, and his role is to keep us trapped in the belief that lithium should be the future. The stupid battery backup system he stole the contract for in Australia sucks and was designed entirely out of lithium ensuring its obsolescence. For 60 million dollars he bought about 10 million worth of lithium batteries and just connected them in parallel and series in a way that any 8th grader could when it should have been done with a new generation of mag lev fly wheel batteries which could have a risky need innovative.
