I think I read something about the tesla turbine ripping itself apart if it is going too fast and or has a to big disc, is that true and could you test that?? (mb some cool slowmow) And you could also test different entry flows, disk materials, disk spacings and different fluids?

[@lootemperor]

this technology is dangerous unreliable needs open Flames if you were to use Steam so it would be hot and burn air compressors use major amount of electricity and are load this turbine is also load it would not run or last as long as a thing that already exists called a generator moving it would be impossible when running you can kick a generator throw a wrench at it drop it it would still work and a shitty one could run for 3000 hours for like $300 it wasn't created or used because it's unpractical the wheel already exists

[@buzzsaw7989]

I had heard that too. Something about the faster it spins, the higher the efficiency and modern turbines have a 95% efficiency. Unsure of that is true but it is also neglecting the necessary technology to build, maintenance, and material sourcing. The very reasons why electric cars and batteries have to last longer than a combustion engine can last in order to pay off. I thought it was like 100k miles in countries with 100% green energy sources. Most countries do not have enough green energy to make electric cars worth the effort. It's mostly because of the battery.

It'd be cool to see data on this. Dynograph it, and efficiency tests.

As far as efficiency goes… (mind you this is a copy pasta 🍝 so it’s a bit long but it’s worth the read.) …My 2650watt electrical load run came in with a very low ball calculation of 40% isentropic efficiency. To start off, mind you that includes generator losses, 3 phase rectifier losses, and inverter losses to the electrical load that were not accounted for. So the turbine off the bat is already most definitely doing better than the 40% isentropic efficiency I’ve calculated from the already low ball test results. But for now I’ll just assume 40% isentropic efficiency so that I’m not over claiming what I can prove it can actually do for the time being. (I have nothing in the long run to benefit by overstating my numbers and only my legitimacy to lose. I’ve worked hard for my physics degree and don’t intend to tarnish it for a couple of extra views on the internet.) As far as inefficiencies to the system to fix, there’s 10x crappy ball bearings in this version, 2 crappy RC car gears, both losses will be gained for power out with a direct to shaft generator. (Minus two gears and 8 crappy ball bearings) There’s an 1/8 of an inch of space between the turbine endplates and the casing endplates on both sides of the TesTur. That’s a 1/4in of open flow area around the 2in wide turbine (that only even has a total of 0.75in wide of spacing between all the tight disc spaces for torque to begin with.) That means 25% of the open space for flowing through the casing, between discs and between the casing and turbine endplates, is just free flow over the side of the turbine still. (I’m using the absolute bottom of the barrel of machining equipment right now in my garage 🤷‍♂️) There’s no labyrinth seals yet to even attempt to further reduce that overflow… The nozzle is atrocious at the moment, when making the variable converging section have a tight convergence it causes the fluid jet to aim more centripetally (towards the axle) instead of tangentially (glancing off the disc tips) which severely effects the fluids natural path. This will be fixed with the new variable nozzle design I’m going with. Then even further in this specific casing’s assembly there’s two “pillars” in the middle of the nozzle. This is because the aluminum plates in the middle of the casing plate stack only had the variable nozzle bar and inlet holes cut out, and not the full nozzle geometry. So those pillars are just vertical bars in the middle of the nozzle for the air to smash into just before going into the turbine (hopefully the wet steam tests will just erode them down 🤭) Before all that there’s still about 100ft of air hose between the tanks and the turbine… plus a shell and tube heat exchanger and a TON of elbows and fittings. I’m sure I’m forgetting something too but between all that being fixed… I can almost guarantee we will be in the 60-70s % range and that’s all just still with room temp compressed air. Most forget, I’m using room temp compressed air and never went over 20psi at the nozzle for these tests. (Pressure differential and temperature differential govern efficiency) And even then I still only even have a single stage on it yet. Everyone wants to compare it to the efficiency of a very high temp, high pressure (1000°F & ~1800psi) multibillion dollar 15-30 stage steam turbines… 😮‍💨 That’s apples to rocket ships. 😅 But considering Rankine Steam cycles get theoretical max about 33% of input heat (due to latent heat of condensation and that’s without any regenerative boiler feedwater preheat, air fuel preheat, etc) and then 40% isentropic efficiency (considering the turbine as is) we’re looking at 13.2% thermal efficiency with steam. A more apt comparison for the TesTur would be something an individual can actually purchase, like 1-5kW piston gas generators that you can get from Home Depot or Lowe’s. These get 15-22% thermal efficiency off the plant floor. Good luck getting that 1 year down the line or later with all those moving parts. Also for reference, industry standard for micro bladed gas turbines is 25% thermal to electrical. Whole system efficiency can go higher in Combined Heat and Power (CHP) system, but alas the TesTur would see the same whole system efficiency increase in a CHP Auxiliary Power Unit (APU). In the TesTur you gotta replace…? 🤔bearings…? And still even then, only maybe 🤷‍♂️ depending on how good of bearings, balance, lubing, cooling. The TesTur, and other bladed turbines, only have one moving part. 🔥 So if those piston generators drop efficiency, even at all, the TesTur on its worst day is competitive with a gasoline piston engine electric generator.🤓😬🤷‍♂️ And the TesTur can handle any fuel that can burn, even solid particulate fuels like powdered saw dust, pulverized coal, powdered iron, biomass, etc. (noting the number of those that can be acquired without spending money… 🤑 opening up “low monetary cost”, even carbon neutral, fuel options for MILLIONS around the world) We have to remember that the TesTur doesn’t have to be the holy grail to be worth using if we have free fuels readily available like biomass, and even waste heat already being dumped out into the air and not used for anything. The TesTur just has to be a viable option for some to be worth doing. Even more, the mere fact that I’m using a low temp fluid for my 40% isentropic efficiency calculation means my TesTur efficiency is severely limited by thermodynamics and fluid dynamics. Increasing temps will automatically increase my turbines efficiency. This is because gasses have an increasing viscosity trend as you increase the temperature. This leads to increased isentropic efficiencies in the TesTur from reduced slip on the discs. (Meanwhile, we’re already talking about a piston engine using combustion temps as is.) Whereas bladed turbines see the increased viscosity as an increase in drag loss through the turbine blades. So we can’t always count on seeing increased isentropic efficiencies in a bladed turbine in practice when we go from low temp to a high temp. Again, to reiterate, this increase in viscosity in the TesTur only works to enhance the working action of the TesTur. (That being viscous adhesion to the disc faces increasing torque.) That’s all on top of the increased thermodynamic efficiencies of using a higher temp elastic fluid too! 🤓 Even more, the mere fact that I’m using a low temp fluid for my 40% isentropic efficiency calculation means my TesTur efficiency is severely limited by thermodynamics and fluid dynamics.

That’s all on top of the increased thermodynamic efficiencies of using a higher temp elastic fluid too! 🤓 The disc spacing for room temp gasses is not going to be the same for combustion temp gasses/steam because the viscosity of either increases by 3x fold. And I’ve designed these spaces for a higher temp fluid with a slightly higher viscosity so these will inherently be too wide at the current temperatures being used. So as we increase temps along with all these other really easy to fix mechanical issues (that only are a thing because I’m building this in my garage on a junk cnc machine) I have no doubt we will see more than competitive isentropic efficiencies compared to bladed turbines, let alone whole system thermal efficiencies that are through the roof. This is because of the heat recovery systems that can be added with the cost savings of using a TesTur vs a VERY expensive, and in my opinion, relatively delicate bladed turbine. Just getting tighter casing clearance with the turbine should give me at least 20% points back on efficiency putting my testur at the 60% range. Coming in with a 19% thermal efficiency in a Rankine steam system without any kind of thermal recoup.

[@CharlieSolis]

@@Chloe_Priceless hey thanks for the question! Simply put, it’s just because I’m using really cheap desktop cnc machines. With proper machining this wouldn’t have any issues with leakage over the side of the rotor. Along with adding in axial and radial labyrinth seals to the turbine to further reduce any overflow. If you look closely at component 27 in the Tesla turbine patent 1,061,206 image, you can see the labyrinth seals that Tesla drew in. They are very hard to see if the image looked at is low quality because they are so faintly drawn in. But I have high res photos of a lot of the original patent photos as well as the blue prints for the famed Tesla turbine that’s in the main Tesla Museum. I didn’t pay for the copyright licenses to show them in videos and stuff though 🫤 I hope this answers your question! Let me know if I missed anything.

[@vesstig]

And his comment was never heard from again

[@PrisonSoap]

It would take some iterations and R&D but theoretically possible. But with how far we've progressed with turbine blades, having it powered by wind would be cool, but probably not as efficient as u hope. Now if u had say attached it to a moving car or used it on a nearby stream with running water, you would have an easier time. I remember reading that at higher RPMs the blades start to warp slightly and lose efficiency. In Tesla's day they didn't have the manufacturing we have today, there are people actually trying to recreate his engine(gasoline powered) with higher efficiency than current cars. U could also potentially make a steam powered one at home, with some pipe and a tesla turbine printed in high heat plastic at the end.

[@Bullsquid592]

Sounds cool but I'd guess there's a reason small, close to the ground wind turbines aren't really a thing. Plus having it attached to a vehicle seems like more hassle than its worth with needing to take it off every time you drive, unless you find an infinite petrol glitch.. in which case screw the battery

[@joshuajames2785]

And if you incorporate something similar to a turbo on a diesel engine you could get more air compression=increased boost in psi. Add an electronic waste gate and now you can control the psi

[@kevinrdunnphs]

I'd be interested to see how efficiency compares with a similar output parson's turbine. Perhaps running both on steam, using a fixed amount of fuel and measuring the kWhrs of output

[@24680kong]

They're less efficient overall because they rely on viscosity (high friction) instead of transferring kinetic energy. That viscosity turns kinetic energy into waste heat instead of turning the turbine. That's why nobody uses them.

[@richardandreotta9396]

That's why you build a tiny one that is heat sinked to a larger one that itself is heatsinked to a larger one and you build them up like russian nesting dolls @@24680kong

[@The-KP]

Tesla turbine efficiency can reach up to 80%. What limits its usefulness is it becomes less stable as disc diameter increases. You can increase the number of discs along the shaft, and increase the shaft length, but there's a maximum velocity and torque that can be reached based on the diameter and flow rate and pressure. So, it's more useful in smaller applications compared with conventional turbines like the Kaplan.

[@Cheebzsta]

@@The-KP "Up to 80%" sounds... optimistic. I've gone through a few dozen papers on the subject and I don't think I've seen a single build over about 50% isentropic which is honestly pretty good for something anyone can make but is objectively pretty poor. Keep in mind that the isentropic efficiency is not the thermal or cycle efficiency. They're related (higher isentropic = better overall efficiency which boosts thermal efficiency) but the numbers are different enough that it's wise to uncouple them in your mind lest you come away expecting a 33% improvement over existing power stations. Sadly we've not really seem a unit's overall thermal efficiency. Thus far we know Charlie's got a Tesla turbine to work but don't have easily verifiable numbers to go on with regards to its overall fuel efficiency. Which will be an issue if it's sold as, say, an off-grid generator but if it's overall electrical efficiency is 5% than that'll be trickier. Making 5kwh of electricity that requires 100kwh of thermal or, in real terms, about 12kg of charcoal. Per hour. Aassuming 250kwh of personal electricity a month, which is below the average household where I live in British Columbia, you'd be looking at 3 cubic meters of charcoal burned every month. So unless you have a specific use that requires a LOT of extra heat for industrial purposes that'd be tough to justify outside of peak thermal needs. Maybe with a larger enough thermal battery but that ups the setup cost, etc.

[@ItsMeArda]

I feel like the biggest upside of using a tesla turbine is, like mentioned in the video, the possiblity of using "dirty" steam to spin the turbines. It would be cool if you could build a homemade high-pressure steam boiler and try to get the highest efficiency out of your own turbine. It would make an interesting comparison between conventional steam turbines and a steam-driven tesla turbine.

[@johpfit760]

The problem with using "dirty" steam is that pressure is directly correlated to temperature. The only real upside is the high tolerance to low steam quality. But that's also not really a problem if you use a steam boiler since all trace gases are purged relatively quickly. So all that's left is the ease of construction and cost per unit.

[@bogsp]

how about attaching an evacuated thermal tube to get steam from solar energy? maybe get a couple of them and make a steam module?

[@ItsMeArda]

@@francissmithson398 I was thinking about using salted water or ocean water to create steam. Conventional turbines suffer immensely from steam impurities since they damage the blades and increase maintenance frequency.

[@DeuxisWasTaken]

One of my favourite things about the Tesla turbine is that it gets more efficient with RPM due to the centrifugal force compressing the air and making it do more rounds before escaping through the middle, also increasing its stickiness to the blades. That moment when the air and blades synchronise and it noticeably jumps in speed is awesome. I saw it somewhere on youtube years ago and it blew my mind.

[@Cheebzsta]

That moment when it "hits" I think this is what Mikhail Goldshtik's talking about in his work describing the transition between turbulent flow into a laminar flow where the vortex stabilizes. Essentially the tornado hasn't happened properly until that moment and then BAM the thing takes off! It's pretty damn cool, I agree. If you dig that you might like Goldshtik's work. For a scientist he was pretty DIY. :)

Too rapid of acceleration with a rocket motor, maybe perhaps it could work, but majorly redesigned to take in to account the physics at play

[@brandonatherton]

I think steam is probably the best medium. While water would work, the extra viscosity would likely cause the water to back up and slow down the overall rotation speed, since the spaces between the disks are so small. Furthermore, I think you would have to be even more precise with the design to limit any potential for backflow or disruption of flow. I could see water potentially being better for lower speed, higher torque scenarios, but I think steam would be the happy medium. More viscosity than air, but also maintains higher speeds than water itself.

@@CharlieSolis Hey i was thinking, how about maybe try to make the finish of your disc rotor rougher, increasing the cohesion even more? Btw you mentioned that the turbine generates the biggest torque at low RPM's how does that work? It'd be nice if it could have good torque at greater RPM's still, increasing the power band basically, so it could run on high and low pressure and keep a good torque going. One thing about though that i thought about the longevity is the centrifugal force, you said you use aliminium discs. But wouldn't aluminium result in a shorter life, since it experiences fatigue failure way more easily than steel, so maybe a test at high RPM's with steel and aluminium discs would be worth doing.

The TesTur, and other bladed turbines, only have one moving part. 🔥 So if those piston generators drop efficiency, even at all, the TesTur on its worst day is competitive with a gasoline piston engine electric generator.🤓😬🤷‍♂️ And the TesTur can handle any fuel that can burn, even solid particulate fuels like powdered saw dust, pulverized coal, powdered iron, biomass, etc. (noting the number of those that can be acquired without spending money… 🤑 opening up “low monetary cost”, even carbon neutral, fuel options for MILLIONS around the world) We have to remember that the TesTur doesn’t have to be the holy grail to be worth using if we have free fuels readily available like biomass, and even waste heat already being dumped out into the air and not used for anything. The TesTur just has to be a viable option for some to be worth doing. Even more, the mere fact that I’m using a low temp fluid for my 40% isentropic efficiency calculation means my TesTur efficiency is severely limited by thermodynamics and fluid dynamics. Increasing temps will automatically increase my turbines efficiency. This is because gasses have an increasing viscosity trend as you increase the temperature. This leads to increased isentropic efficiencies in the TesTur from reduced slip on the discs. (Meanwhile, we’re already talking about a piston engine using combustion temps as is.) Whereas bladed turbines see the increased viscosity as an increase in drag loss through the turbine blades. So we can’t always count on seeing increased isentropic efficiencies in a bladed turbine in practice when we go from low temp to a high temp. Again, to reiterate, this increase in viscosity in the TesTur only works to enhance the working action of the TesTur. (That being viscous adhesion to the disc faces increasing torque.) That’s all on top of the increased thermodynamic efficiencies of using a higher temp elastic fluid too! 🤓 The disc spacing for room temp gasses is not going to be the same for combustion temp gasses/steam because the viscosity of either increases by 3x fold. And I’ve designed these spaces for a higher temp fluid with a slightly higher viscosity so these will inherently be too wide at the current temperatures being used. So as we increase temps along with all these other really easy to fix mechanical issues (that only are a thing because I’m building this in my garage on a junk cnc machine) I have no doubt we will see more than competitive isentropic efficiencies compared to bladed turbines, let alone whole system thermal efficiencies that are through the roof. This is because of the heat recovery systems that can be added with the cost savings of using a TesTur vs a VERY expensive, and in my opinion, relatively delicate bladed turbine. Just getting tighter casing clearance with the turbine should give me at least 20% points back on efficiency putting my testur at the 60% range. Coming in with a 19% thermal efficiency in a Rankine steam system without any kind of thermal recoup.

@@kevinbuiiedOf the sun’s light energy that hits the earth 10% is UV, 25% is in the visible spectrum, and a whopping 65% of it is in the infrared, heat, spectrum. Solar PV cells can only use a portion of the visible spectrum and use none of the IR spectrum and in fact lose efficiency from heating up from the IR. So at best you can get maybe 20% of the suns total light energy to electricity to charge and discharge a battery at 90%. So only 18% of the suns light energy gets to your wall plug. And then UV light makes them go opaque and be at 1/2 their rated power in 10 years. So, conservatively down to 10% of the suns light gets turned into electricity 10 years in. With solar thermal collectors you can collect all 25% of the visible spectrum and all 65% of the IR spectrum and store it as heat in a thermal mass. So 90% of the suns light energy can be collected and stored as heat in a thermal mass. Let’s say 10% loss on storage So 81% of the suns light energy is then available to be put through a steam Rankine turbine system, which at theoretical best can get 25-33% thermal efficiency to electricity. 44% is the recorded best (And that’s without any thermal recoup, boiler feedwater preheat, etc to bring up the Rankine cycle efficiency and/or going to an organic Rankine cycle with a refrigerant in the closed loop instead of steam for higher pressure gradients with the same temp gradient, for high efficiency) So that’s 20-26% of the suns light energy can be put directly out as 60hz 120vAC. About a 10-45% increase in energy out for the same footprint of collectors. And then even after that ALL the heat energy rejected/dumped out by the condenser from the latent heat of condensation and loss not turned into electrical power can then be used for home heating. Sooo since about 60% of the energy stored goes out the condenser, if it’s used for heating then somewhere like 70-80% of the suns total light energy can be utilized for electricity and heating. Admittedly those are high temp steam system numbers for the Rankine thermodynamic system. But with the property built thermal batter that stages a high temp sand/rock thermal mass battery (at least up to 500° storage) embedded in the center of a water thermal mass batter (Up to at least 80°c if at atmospheric pressure) the water mass batter can be used to come up vaporize and then the high temp thermal battery is used as a superheater. Solar can get that hot if done right but I would personally suggest a hybrid biomass and solar thermal system to make sure there is carry over for long no sun periods. Yard clippings, annual leaves, etc can be collected for use to charge the battery. And if done right biomass can not only be carbon neutral but carbon negative. And again admittedly this might not be a solution for everyone around the world. But if you need heat too this will be a banger 😎 And considering geothermal 🤤🤤🤤 when even just one geothermal site in California has more energy than the US needs for the next 1000 years and TesTurs see no damage from multiphase motive fluid flows I’d take even just 10% thermal efficiency over the zero that the bladed turbines can offer. The same goes for solar steam boilers because it’s very difficult to have a residential solar boiler that doesn’t produce wet steam. Furthermore bladed turbines can’t use low grade fuels like biomass, woodgas, and definitely not solid particulate fuels like sawdust, powdered coals and pulverized iron. That’s not an issue for the TesTur for the exact same reason that condensate and cavitation in wet steam doesn’t damage it. Because there’s no lifting surfaces for the particulate to smash into.

[@aaronlavers3148]

Man this is absolutely fascinating. I'd be really interested to see this expanded in another video where it could be field tested in areas where 'low quality' steam/sources were available as a real-world test!

Use the Tesla turbine to display mechanical torque by using it to lift, move, or drive something. Amazing content keep up the good work!

[@Argoon1981]

Not that I know much about this but based on what i know, I don't think it would be good for that because steam or air has less to push against than on a blade turbine, so it would in principle skip or slip but It's rotation could be used to power a AC electric motor (using a DC to AC transformer) that itself pulls up or down a heavy object, two Nikola Tesla inventions working in unison. :)

[@iXenox]

Also comparing it to other turbines that he has!

[@CharlieSolis]

Hey thanks for the suggestion, I love this idea! We will be doing full combustion gas and steam turbine’s here very soon and we will be putting them in everything from lawnmowers, to motorcycles, EV backups generators, to full power by wire automobiles. You could realistically remove the 1500lb battery pack from a Rivian truck and stick one of our full combustion gas TesTurbogenerators in the bed and just plug the generator’s rectified DC output output into batteries hook up and it would work just the same. And for half the weight of the battery we could provide a TesTurbogenerator and fuel tank that could far out perform mileage than the battery pack due to the weight loss alone. Liquid fuels have a 20x energy density than battery systems, which is the name of the game for land vehicles and even more for aerial vehicles.

[@CharlieSolis]

@@Argoon1981hey thanks for the comment ❤️‍🔥🙏 to be clear there’s no issue with the fluid having enough to grip on with the discs. The difference with the Tesla turbine is it doesn’t rely on the fluid to “push”. Infact the fluid actually pulls on the disks as the fluids kinetic energy is transferred to each disc in the shear forces/cohesive forces within the fluid and then through the fluids adhesive forces then attach the fluid to the disc material at a molecular/electron orbital level. When designed correctly the TesTur can output plenty of torque and power and will have no issues in high torque demanding operations. If you have any further questions I’m always happy to answer them! 🤓

[@CharlieSolis]

During power output the turbine was spinning at about 12,500RPM For an exact calculation of the torque it’s outputting in this 1200 watt work light load test specifically, Hp = Torque * RPM / 5252 Torque = Hp* 5252 / RPM 1200watts = 1.63Hp Torque = 1.63hp * 5252 / 12,500 = 0.684ft-lbs of torque These preliminary tests are just to see how much electrical power can be produced with room temp compressed air driving the Tesla turbine. Peak numbers to the shaft we’ve measured is 6.22ft-Ibs of torque at only 4150rpm and +4.25kW between 6000-12,000 rpm on the dyno. The TesTur nozzles never went over 20psi at the nozzle for the 2650watt electrical load test and not over 40psi at the nozzle for the 4250watt dyno test. This is so I can get a baseline for what to expect as I increase the temps to combustion levels. When using elastic gasses the counterintuitive thing most overlook is that the viscosity of gasses goes up with temp. So not only do we see an increase in thermodynamic efficiency from increased temps but the TesTur isentropic efficiency also goes up due to the reduced slip from the increased viscosity. Let me know if you have any questions!

[@Bildo1986]

I'd love to see this on a larger scale. I work in power generation and think this would help make maintenance so much easier.

[@CharlieSolis]

Hey thanks for the comment! 🙏❤️‍🔥 We are working on it! Next bench mark we are shooting for is 10kW then going for 100kW and 500kW with our 10in diameter turbine once multi-staged. Then we will be going to larger discs. One step at a time though! 🦾🤓👨‍🔬 Thanks again!

[@hydranos1058]

@@CharlieSolis Can you talk at all about the tradeoffs of larger discs? My intuition is that you'd be trading max RPM for improved torque. But there's also the fundamental limitation of the disc being unable to spin once the outer edge of the disc reaches a certain multiple of the incoming fluid's speed. (And the multiple probably isn't 1x because a point on the inner part of the disc will be spinning slower than the air up to the point where you have to exhaust the air. But once the outer edge is spinning faster than the air it would be slowing the system down because of drag?) Then I'm sure for a small operation there's challenges related to manufacturing larger components. And eventually your disc will spin itself apart even if you can provide it with infinitely fast input fluids. Semi-related to discs blowing up: how about graphene as a disc material at some point in the future? That seems like it would provide the theoretical limit of disc surface area to strength and thickness.

I'm really curious about this too. Even just with the aluminum, testing a gradient between smooth like a mirror and so rough there are gouges taken out would be really cool to see. Maybe it wouldn't be as simple as "x finish is the best", but instead certain finishes might perform better for certain requirements. If the finish does significantly impact performance, I could see multi-finish disc assemblies becoming a thing, too.

[@CharlieSolis]

Hey thanks for the comment! And really cool information. I hadn’t hear if Fantom Vacuum before. I’m going to look into them now! As far as Tesla figuring this all out, he briefly notes on this in his “Dr. Tesla Talks of Gas Turbines” article. This is what he said, ““I have been working at this a long time. Many years ago I invented a pump for pumping mercury. Just a plain disk, like this, and it would work very well. ‘All right,’ I said, ‘that is friction.’ But one day I thought it out, and I thought, ‘No, that is not friction, it is something else. The particles are not always sliding by the disk, but some of them at least are carried along with it. Therefore it cannot be friction. It must be adhesion.’ And that, you see, was the real beginning. “For if you can imagine a wheel rotating in a medium, whether the fluid is receiving or imparting energy, and moving at nearly the same velocity as the fluid, then you have a minimum of friction, you get little or no ‘slip.’ Then you are getting something very different from friction; you are making use of adhesion alone. It’s all so simple, so very simple. “This is the greatest of my inventions,” Tesla went on with great enthusiasm.“ Hope this helps! And thanks for the info!
