Does the torque depend on speed the same way efficiency does? Because if yes, a Tesla turbine would have less torque on start up, and would get stronger as it spools up. So with the right amount of resistance it might keep up the performance at high speed, but stall if it gets too slow. I don't know if traditional turbines behave like this too, but this seems like a setup for a very dangerous feedback loop.

@@NwoDispatcher Yes! I have seen this in Jeremia's recent releases. What do you make of it? I can only intuit that a thermodynamic process in which "kinetic" (both mass flow 0.5mv^2 and thermal (latent heat) energy is converted to rotational torque inside the turbine as a result of some kind of phase change and at some point this becomes self-sustaining, mass flow increases and the "resonant" pickup of energy takes place. Does this make sense or not? I have seen it happen, and I trust Jeremia is not fooling us. I am also inclined to ask if we need to go to the trouble of a cryopherous containing hot water in the first place? If instead a refrigerant like Butane were used, then at 2 atmospheres it is boiling at 25'C. A BPHE acting as an evaporator warrants pumping the warm water around under ambient pressure conditions without mixing it with our heat carrying fluid. This refrigerant can be optimised for the temperature gradients experienced. In contrast, flowing the heat storage medium itself through the turbine will always mean introducing dissolved O2 and N2 into the condenser, and that effectively is a dilution or contamination of the energy density (enthalpy density?) within the turbine. In practical terms I think the spin-up might be accomplished by any number of means (using compressed air, gas, the alternator during powered up) or by "cheating" approaches in which external energy is applied before the "heat extraction" phase of conversion. And we need T and P and flow rate sensors all over the system giving state information as loads are applied. And some handle on a "closed cycle" rather than "open cycle" cryopherous, and an answer to "What becomes of the heat that the turbine does not convert to mechanical power?" If have seen this written as: Heat (Entropy) in Mass Entering Turbine = H1 Heat (Entropy) in Mass Leaving Turbine = H2 Turbine Efficiency (Proportion of H1 converted to turbine shaft power) = X Generation Efficiency = Y (and I am sorry but I have lost the will to write temporarily) H1-H2 = H1 x X H2 = H1 x (1-X) My point is the heat in the mass leaving the turbine is not necessarily wasted to the environment (something Charlie Solis is rightly banging on about), it can be used or re-circulated back to the hot side. Likewise there is potential for recovery of utility from the cold side of this process.

The machine will, generally, perform its maximum work when the effective speed of the runner is one-half of that of the fluid; but to attain the highest economy, the relative speed or slip, for any given performance, should be as small as possible. This condition may be to any desired degree approximated by increasing the active area of and reducing the space between the disks.” -Nikola Tesla

In steam turbines, when the steam exits the final stage it is still steam but at a high level of vacuum, but on a Tesla turbine the power medium has to work its way inward from the outer edge towards the center against the force of the spinning wheel which requires additional pressure to overcome. This sounds like it could be a loss of efficiency to me.

In the explanation you missed one of the coolest aspects of the Tesla turbine. He uses the principle of conservation of angular momentum and it kind of self induction Loop a bit the way Tesla coil uses the voltage gain earlier in the coil to create a step up later in the coil which creates a voltage draw that increases the voltage earlier in the coil in a runaway self-amplification of voltage. In particular, any unit massive fluid towards the outside of the turbine has to increase its angular velocity as it approaches the center to conserve angular momentum, as it increases its angular velocity the speed differential between the center of the turbine and the fluid is increased driving the center harder causing the the turbine to rotate faster which in turn accelerates the fluid at the edge of the turbine so that it gains angular momentum, which start the cycle all over again. It's a self-inducing system that maximizes the frictional transfer between the fluid and the disc. The fundamental problem that I see with the design is that as it spins faster to keep the liquid moving in a circle you need higher and higher centripetal force which creates a high pressure around the edges, putting a lot of friction and pressure on any seal you have between the disc and the stationary housing

The video says the rotor must spin at a very high rpm, maybe 50,000 for a 6” turbine. The speed of a turbine is based on periphery speed not rpm. If a 6” turbine needs to spin 50,000 rpm to be efficient like the video says, that’s a periphery speed of 890.1 Miles per hour. If you want a 3 meter disk to achieve close to 891 miles per hour at the periphery, the rpm required is only 7,253. We have materials that can easily reach that speed.

Nikola Tesla patented an improved disc stack patent GB 186,082 in 1921, 10 years after the original and a decade of R&D. Vibration is not an issue when built correctly. “In the new design I employ two heavier end-plates which are machined tapering toward the periphery for the purpose of reducing the maximum centrifugal stress as much as practicable. The inside discs, of relatively thin material, are rolled, forged or ground tapering in like manner and with the same object in view, but this may not always be necessary and plates, made of sheet metal of substantially uniform thickness as furnished by the mills, can be employed. Each of the thick as well as thin plates is provided with exhaust openings, leaving a solid central portion like the hub and spokes of a wheel. Star-washers of similar configuration serve the purpose of keeping the discs apart in the center and for the peripheral spacing the thin plates have small holes drilled in them on a circle, or circles, of suitable diameter, and in these are driven tight-fitting studs which are upset at both ends by a special tool so that they will project beyond the metal on each side a trifle more than the thickness of the star-washers. When the plates are put together the separating studs do not come in line but are straddled in order to give opportunity for slight yielding, thereby eliminating constructional difficulties which might be caused by unevenness or other mechanical imperfections. Thus the rotor can be finished closely to predetermined overall dimensions and will run true on the outside even if the thin inside plates should vary a little in thickness or be slightly warped. To simplify this arrangement I provide only every second plate with studs, using plain ones between. Furthermore, with the object of cheapening the manufacture I dispense altogether with the former, accomplishing the spacing by means of small bosses or protuberances which are raised in the plates by blows or pressure and provide a die, practically reducing all the machine work on a thin plate to a single operation in a stamping press. The star-washers, while preferable, are not indispensable and may be replaced by round separating washers of a diameter about equal to that of the hub part of the discs.” -Nikola Tesla “This construction permits free expansion and contraction of each plate individually under the varying influence of heat and centrifugal force and possesses a number of other advantages which are of considerable practical moment. A larger active plate area and consequently more power is obtained for a given width, this improving efficiency. Warping is virtually eliminated and smaller side clearances may be used which results in diminished leakage and friction losses. The rotor is better adapted for dynamic balancing and through rubbing friction resists disturbing influences thereby insuring quieter running. For this reason and also because the discs are not rigidly joined it is safer against damage which might otherwise be caused by vibration or excessive speed.” -Nikola Tesla

amazing channel. liked subbed, applause and congratulations

I'm curious about cavitation, they work for heaters, instant steam generators. But ive read somewhere that it also helps with aerodynamics. A vehical with golfball size indents spaced an inch apart all over the car will supposedly more aerodynamic because it's ability to resist air friction by using its own cavitational eddy throughout the entire surface. Thus allowing air to flow against air with the boundry of that cavitation air/sound?.. Theoretically speaking it will only show larger improvements upon higher speeds. Research is hard to find on this subject matter, I'd test it myself if i had time and $. Thank you for your video content, i enjoy it very much!

Even shown proof of powering real up to 2650 watt electrical loads at only 9500rpm and and never using more than 20 psi at the nozzle 🤭 Add on the bacon bits of gasses increase in viscosity with temp, they get thicker when they get hotter and thinner/runnier when they get colder, the opposites of most liquids. This increase in viscosity as temps are raised to combustion temps reduces slip on the discs ultimately increasing the isentropic efficiency of the TesTur in addition to the increased thermodynamic efficiency efficiency from using increased temps.

That appears to be a Fitz I-X-L Steel Overshoot Waterwheel a few seconds in. It also appears to have faulty feedstock. A properly designed, constructed, and operated overshot/overshoot is very efficient - 88% to 97% energy conversion.

Funny you should show a Blendtech Blender. In one of my first jobs out of uni, I had to investigate why these blenders various programmed modes weren't running for the expected time when used in Australia. Long story short, the firmware incorporated the AC supply frequency in their timing calculations and it had been hard coded to 60Hz. While doing some MTBF testing on them, I found when used repeatedly, with little break inbetween cycles, the metal blades were conducting heat from the motor into the jug, boiling the liquid medium inside. Will it blend? Sure. It can cook too!

The explanation in the last few seconds for why they aren't used amounts to, "Eh, we just don't do it that way."

The thing I love about this invention is it is soooo tesla. The ability to have the turbine work in reverse is something he made use of in his electric devices. He looked at the water and was like, "you're gonna pretend to be electricity.;" and water being water, it didn't disagree...

I love the effort and love for Tesla turbines but I really wish these multi million subscriber channels would actually do their homework on the TesTurs before making a video telling people entirely inaccurate things about the working machinations of the TesTurs… Despite what everyone erroneously claims about TesTurs, chasing high RPMs is exactly why nobody makes Tesla turbines that actually work. That’s NOT how they are supposed to be run in the first place. TesTurs output PLENTY of torque and power even at low rpms. Efficiency is actually increased by reducing slip. Increasing the disc speed does nothing to reduce the slip, only increase the distance the fluid could slip across the disc which doesn’t increase efficiency. Just listen to what Tesla says to do, 1) increase the fluid speed relative to. the discs (not high speed disc) 2) increase surface area. 3) decrease the disc spacing. “Owing to a number of causes affecting the performance, it is difficult to frame a precise rule which would be generally applicable, but it may be stated that within certain limits, and other conditions being the same, the torque is directly proportionate to the square of the velocity of the fluid relatively to the runner and to the effective area of the disks and, inversely, to the distance separating them.

I build real actual working TesTurs that output actual power and torque even at low RPMs. Half the claims in this video are downright false. It would seem almost no research was done, and it would seem the patent wasn’t even read because the erroneous claim that the TesTur has to spin fast to work just gets parroted over and over and nowhere in the patent does it even say that. The only time it’s supposed to spin fast is when used as a pump/compressor because ALL centrifugal pumps/compressors performance is too speed dependent. “I have found that the quantity of fluid propelled in this manner, is, other conditions being equal, approximately proportionate to the active surface of the runner and to its effective speed. For this reason, the performance of such machines augments at an exceedingly high rate with the increase of their size and speed of revolution.” -Nikola Tesla But when run as a turbine and spun to fast the centrifugal head will counter the incoming fluid flow, reduing the pressure gradient across the nozzle, reducing the fluids final velocity after the nozzle, reducing the mass flow rate through the nozzle and ultimately reducing power. Spinning fast only has a slight increase in efficiency but at the cost of power. Again even Tesla himself knew they weren’t supposed to spin fast and even says they work great at high and low fluid speeds and speeds of revolution. “Still another valuable and probably unique quality of such motors or prime movers may be described. By proper construction and observance of working conditions the centrifugal pressure, opposing the passage of the fluid, may, as already indicated, be made nearly equal to the pressure of supply when the machine is running idle.

Did up to 2650 watt tests of real electrical loads with a 200 gal tank of compressed air stored at 150psi regulated/throttled to the nozzle pressure and dumped until it couldn’t keep going. The 250watt run kept going until the tanks fell below 35 psi, and that trend went up to the 2650 watt run that stopped being powered when the tank dropped below 95 psi in the tank. But yeah these were just compressed air tests. And compressed air is, for the most part, a collection of non polar molecules (O2, N2, CO2, etc) that don’t adhere well to metallic discs, or at least not as well as H2O steam does being a fairly polar molecule which has a much higher adherence to the disc faces. (Think “wetting angle”, also hydroPHILLIC surface coatings can further increase H2O adhesion, and on the other end hydrophobic coatings should increase non polar molecule adhesion. Essentially the right additional surfactants should increase adhesion.) Ultimately this increased adhesion force increases the isentropic efficiency of the turbine from the increased boundary layer thickness. Also there will be higher temp gasses. Which if you’re not familiar, gasses have a viscosity trend with temp that’s the opposite of liquids, they get thicker as they get hotter and thinner/ runnier as they get colder. So the further increase in viscosity, cohesion forces, due to the increase in temp results in reduced slip on the disc, which further increases the isentropic efficiency in addition to the thermodynamic efficiency increase from having increased fluid temps.

@@deucedeuce1572 so I would urge you to read a little more from his “magnifying transmitter” paper. He actually dispels the myth that the government and even J.P. Morgan had a hand in stopping him. In teslas very own words about wardenclyff… “The tower was destroyed two years ago but my projects are being developed and another one, improved in some features, will be constructed. On this occasion I would contradict the widely circulated report that the structure was demolished by the Government which owing to war conditions, might have created prejudice in the minds of those who may not know that the papers, which thirty years ago conferred upon me the honor of American citizenship, are always kept in a safe, while my orders, diplomas, degrees, gold medals and other distinctions are packed away in old trunks. If this report had a foundation I would have been refunded a large sum of money which I expended in the construction of the tower. On the contrary it was in the interest of the Government to preserve it, particularly as it would have made possible - to mention just one valuable result - the location of a submarine in any part of the world. My plant, services, and all my improvements have always been at the disposal of the officials and ever since the outbreak of the European conflict I have been working at a sacrifice on several inventions of mine relating to aerial navigation, ship propulsion and wireless transmission which are of the greatest importance to the country. Those who are well informed know that my ideas have revolutionized the industries of the United States and I am not aware that there lives an inventor who has been, in this respect, as fortunate as myself especially as regards the use of his improvements in the war. I have refrained from publicly expressing myself on this subject before as it seemed improper to dwell on personal matters while all the world was in dire trouble. I would add further, in view of various rumors which have reached me, that Mr. J. Pierpont Morgan did not interest himself with me in a business way but in the same large spirit in which he has assisted many other pioneers. He carried out his generous promise to the letter and it would have been most unreasonable to expect from him anything more. He had the highest regard for my attainments and gave me every evidence of his complete faith in my ability to ultimately achieve what I had set out to do. I am unwilling to accord to some small-minded and jealous individuals the satisfaction of having thwarted my efforts. These men are to me nothing more than microbes of a nasty disease. My project was retarded by laws of nature. The world was not prepared for it. It was too far ahead of time. But the same laws will prevail in the end and make it a triumphal success.” -Nikola Tesla

Can this be turned into a pump? Spin the discs to pump air or water out?

Theoretically yes and no. The center shaft is spinning which you could hookup to a belt to a second chamber which inside has propeller blades and 2 one way valves for an in an out. If your asking if the main section of the turbine itself can be... idk. Someone might come up with some design/modification to do that but I havent come across one yet.

I've always thought it would be easy to take excess solar power, use thst to compress air and release thst air later to generate electricity. This seems like a very easy way to DIY that into reality. Now I just need a massive compressed air tank and a compressor, thankyou action lab for putting the last piece of the puzzle together for me!!

@@CharlieSolis ahhh the TesTurs that you make are amazing! Keep up the great work! Everyone up and down these comments are demanding Tesla turbines can’t work/get low torque/have to be spun to fast to even work yet you’ve got all sorts of proof that Tesla turbines get a butt load of torque even at low rpms!! 🤤 How are these people trying to argue with your conflicting TesTur results? Do they just not know about your work?!

Since the pumped material does not impinge normally on the disks it can be a carborundum slurry or even concrete aggregate. There is vey little wear in the disks.

From experience I can tell the Tesla turbine can work just fine on Low rpm , I've replicated it from the ideas of (Charlie Solis) he can get from his 10inch turbine a about 5 horse power ! YES HP ! For my 7.5 inch 12 disc turbine whit a spacing of 0,5 mm it delivered 0,5hp at 7000rpm at 1,5 barr of steam pressure,. I really recommend checking Charlie's channel if you want to know how the Tesla turbine really works!

I'm not sure if I'm remembering it wrong, but I think Tesla turbines are used for some things in dams when producing electricity. It might also be the Tesla valve.. but there's something ringing a bell.

Would be cool to see a regular turbine with VARIABLE fins so you can optimize the angle and approach a Tesla turbine approach when the load allows. Would love to see that!

@@alangil40 yeah the variable geometry “nozzles” in those turbines are cool. The mechanism for the adjustable vanes is super simple. Although the pivot in them is the wear point over long operating lifespans.

Normal water turbines averages 90% efficiency , some reaches more than 95%. Even pumped hydro ranges between 70-80% where energy is lost in both operations.

missing something... the conversion of the water pressure or head, or potential energy, to kinetic energy, is always 50%. if you block the pipe completely with turbine... no flow, no energy to extract. all potential energy. if the pipe flows freely with no turbine...full flow, no energy extracted. all kinetic. somewhere in the middle, you get half... the peltons exactly the same, but in reverse. the pipe flows freely, the water achieves full velocity. then that velocity converts to pressure when it hits the blade, and the blade retreats at half the velocity... half... half... you will find the turbine is 85 to 90% efficient at THAT conversion... a pelton doesnt bring ALL the water to a complete smooth halt, theres some splash. a francis turbine doesnt quite turn all that pressure into velocity, theres eddies and turbulence...

@@paradiselost9946 what are you talking about is probably betz limit (altough not sure). And its not appliable on gravitational water turbines. It work on wind and open water turbines (with no pressure gradient). There you can theoreticaly take 59% of energy of medium so it can still flow. But in pressure devices like water turbines this isnt aplied since there is pressence of gravitation which is moving water forward to maintain flow.

@@Theeloberto sigh. what makes the water flow? gravity. so head is pressure. and head is potential energy. stationary. doing nothing. cant use it. as soon as any quantity of water starts moving from that height to a lower height, it is converting potential energy to kinetic energy. if it falls freely, it converts all its potential to kinetic. it still doesnt do anything. for US to USE the potential in that head, we have to let it develop kinetic energy. it has to flow. if we stop the flow, we dont do any work. if we dont stop the flow, we dont do any work. we have to stop the flow by HALF. irrespective of what type of turbine we stick on there, we can only use HALF the potential energy available, or half the kinetic energy that may be developed during conversion. the other half has to keep flowing, has to keep moving. betz law is entirely different, as there is no potential to be converted from, its already present as kinetic energy. all we have to deal with is mass flow over area. and if you broke it down to the potential required to induce the pressure gradient that caused that mass flow at that velocity, you would find that betz law is 59% of the 50%... and then turbine marketers get really sneaky and sell you a "90% efficient" turbine, thats actually only 90% of 59% of 50%... and hell, we havent even dealt with the actual generator part yet! but when it comes to wind power (or a mid river floating thing) we can happily ignore that first 50% figure.

Will it work in reverse? Turn the shaft and have a efficient compressor or blower or vacuum pump?

A 4" diameter Tesla turbine that I know of can reach 250,000 RPM. The trick is the fact the outlet to the turbine exits form the center, into the Tesla vacuum cycle. Tesla has stated his larger design needs 6 stages. But a 4" size 2 stage turbine can produce 125hp at 250,000 RPM.
