@@andrewselberg649oh were you the dude in the back when everyone cheered? Yeah you got a good gig...lucky boy lol say hi...dig his look...like he came from that era...enjoy 😊
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?
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.
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
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.
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
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.
@@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.
@@CharlieSolis Same here! I've been trying to make him aware of your content for a while. Did one of you reach out to the other or did a comment lead to the connection?
Honestly, as a theme for the channel, I would be fine just testing a bunch of parameters of this engine with Charlie. I'm not an engineer myself, but I imagine that there's a lot of R&D still left in this thing that many of us would be fascinated to see in a followup video or three. Thanks for making a video on this!
Suggestion: Easy to print wind turbine that can actually charge a reasonably powerful battery (such as a car battery), that can be mounted to a motorhome or a stationary car?
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.
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
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
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.
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.
@@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.

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.

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.
imagine when they pump plasma so that magnetic field modifies viscosity. how many electronvolts plasma can reach beeing cold. when it makes enormous pressure but low temperatute plasma is it possible.
@@CharlieSolissorry not read all of it … but came across the too much space free air flow section … why not using a hard disk drive and modify it ? There is as little as nearly no space left between the platters so maybe orientate on that knowledge ?
@@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.
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!
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.
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. :)
What a brilliant channel and video. Without guys like you and the creator in the video, the Telsa turbine would have been consigned to the bin after a brief look. The fact he took a deeper look and got it to work when others would have gave up is fantastic. How many more of Tesla's ideas need a fresh look with an open mind?
I’m glad you featured Charlie Solis and his work. I’ve been following him for years. He is a national treasure. I hope you can do follow up with his cryophorus, or his plasma jets.
Loving all the scale builds on uncommon mechanisms! Have you considered doing a video on the Sarich orbital engine? Was prototyped in the 70’s, would be cool to see one built for compressed air! Apparently even Wankel looked at the piston motion.
Why do you think that? For me its not intuitive for water to be better? Well it might cool the disk which might reduce the expansion, but just a thought tho
@@vyvyyv8vohvgu77 I think it sticks better to the surface because of its higher viscocity so more energy is convertet into motion. But wouldnt it be interesting too, to try this with Steam
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.
Long time subscriber, first time poster. Your channel has got to be one oe the best ! Not only do you show how you came about the idea of testing a theory BUT, also the hurdles you encounter, what you did to over come them AND, your failures. It has long been that a smart man is one who learns from his failures and mistakes. You have exemplified this to its maximum. THANK YOU Ssooo much for all of your work. PLEASE DO NOT stop ! 😊😊😊😊😊
Love the video, I'm 27 year old blue collar worker(plumber) working on an invention! Your videos are very helpful. Would be dope to see a video on the complexity of treating water 💧
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. :)
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.
@@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! 🤓
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!
Not only makers should help eachother, we all should! Love this video man, im in extacy for seeing someone take Tesla his genius inventions, and evolving it so it fits more in the day to day life Keep on doing the great work you do man, youre one of the few channels that, when i see a new video, i emmediatly click on it!
When you understand how it works with steam your mind will be truly blown. It functions as a condenser, extracting almost all of the energy before it escapes.
As a woodworker please look into how dangerous the table saw cross cut technique at 9:54 is. You’re a smart guy Charlie, the world needs you in one piece.
Yeah, as someone who has had wood kickback at me with luckily no injuries... that shot made me shudder. Didn't see a riving knife on the blade either, but I could be wrong.
Curious to hear the longevity of a unit. I realize Charlie isn't building them for that at this moment but would be great to see. Even "can we run this for [x] hours straight at 20psi" with good data monitoring. Hopefully he starts raising money to make it work :)
Hey thanks for the comment! ❤️🔥🙏🦾👨🔬🤓 We’re working on the residential closed loop steam Combined Heat and Power (CHP) system right right now in fact to be able to do endurance tests next! Just finishing up the hot water supply circuit for the boiler side and it’s go time! Stay tuned! Again thanks for the love!
@@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.
@@CharlieSolis, if you had 50kg of water at nearly 100C and boiled all of it, that would take approximately 113,000kJ of energy. How much of that energy could be recaptured by this turbine?

@@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.
Yaassss!!!! Well done Joel! This was so good! Andrew and I had so much fun hanging out with you for the week! 🙏❤️🔥🦾🤓👨🔬😎 Thank you for coming out and spending your time with us. Until next time!
@eblman5218 In a different video i heared that one of the big problems of those tesla turbines are the centrifugal forces. So heavy discs are actually counterproductive.
@@CharlieSolis aw shucks man ☺️! Same to you brother! And seriously, take a friggin bow dude ;) You've been putting your life energy and passion into this work for a while now! And one extremely exciting prospect (and a specific passion of my own, as I think you know) is that as you do production runs, or builds, and gain momentum, you can evolve to a point where more time can be devoted to optimization - at both component level and system level. And you clearly have the tools and talent to climb those mountains. Just as you conquered the torque issue, i believe you still have many dragons you will slay in this quest for continuous improvement. You da mannn! Very exciting Charlie! Can't wait! 👍
@@Charlie-Oooooo aw dood… your making me blush 😊 you’re too kind! Thanks for coming along on this adventure with me! It’s been a long haul so far and we’re just getting started!
I like the way you think about creators, helping eachother in making their creations. I watch your videos for the same reason that I get to see new invention, different perspective, you share a energy of doing something.
This dude gets me so interested in engineering things I never would have known about before, love it. As for the video idea, maybe looking at some invention the creator deemed a "failure" and trying to recreate it and improve it?
I think it would be really cool to have a video of you studying the relationship between blade spacing and the ability to generate RPM and torque using fluids with different viscosities. It would be cool to see the impact of a higher velocity viscous fluid like the Devil Toothpaste.
The principle of operation is boundary layer shear force. The closer the vanes less blow by there is. Also, it is an extremely effective water pump if you want to pump water. Just, be respectful of how powerful a laminar flow of water is.
Just astounding!!! I am always like a little kid on Christmas morning when you post a new video! And while I really love your projects, it's also really cool when you do ones like this introducing your viewers to other channels or makers and their projects!
This is incredible. I'd love to see a comparison of energy consumption/output of this turbine vs other turbines. I'd also love to see the torque of that thing in action. Great work as always, Integza!
The reason why Nikola Tesla never made the Tesla turbine mainstream was because it was literally so efficient that the materials at the time would have ripped apart from the speeds it reached
Here's my video idea! It would be expensive but I think testing different materials and surface finishes on the disks could pull a non-insignificant amount of additional power out of the generator, I'd start the surface finish tests on the cheapest material if it were me lol.
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.
@@poipoi300 I never even thought about optimization across multiple platforms, I'm absolutely sure different finishes would result in higher or lower torque in different flow or environmental conditions even within the same flywheel. I could never do it but I will sit and watch a 30+ min. Video on it and smash that like button lol
@@devonmcnealy8900 Oh I wasn't thinking of different environmental conditions, but yeah I assume you could totally take advantage of that. Say your fluid is full of heavy particulate, it might be good to have small grooves to catch their inertia before spitting them back out.
As someone who has been involved in cutting edge technology for over 30 years when it comes to process control, I love to see great new uses for existing tech and also new ideas. I tip my hat to you sir, I have spent the last 3 hours watching your videos. Your habit of creating videos that blow our minds is a gift. Please keep it up.
The man had a pocket vibrator that could shake whole buildings. The turbine was hardly Tesla's best invention but that's a matter opinion. Great video tho and how awesome it is that made a working model. Keep up the good work my dude...
I always enjoy your videos! I would love to see a head to head of all the different generators you have avaiable to see what has the best output potential for the longest period.
His videos and community posts on his TH-cam channel are a goldmine of info! He does have a few posts about wireless transmission of energy and a few videos - some of them may be on his Instagram too.
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!
@@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.
While we are on steam power, I think it would be super cool if you could do a video on the Doble e 20. One of the absolute most interesting applications of steam engineering in my opinion.
video idea: make a mini generator to charge your phone using the blade-less turbine and some kind of steam source. love your vids keep up the awesome work!
It's great to see more Nikola Tesla's inventions on your channel, really enjoyed it! I wonder if it would be possible to build a small car with this and some kind of boiler with steam.
You should do a follow-up video with everyone that has won a 3D printer. You can ask what they have created with it and to allow them to talk about how the printer has helped them with their creative process.
For the 3d printer, I recommend a video as a follow up to how these turbines could be implemented in a real life scenario. How could it get natural energy?
I’d love to see a video about optimizing a hydrodynamic drive, using electromagnetic energy to drive a submersible. I’m sure there’s a lot of different variable you could test
This is really cool, but the thing that fascinated me the most was actually the way they did CNC on those thin pieces of aluminum. Would that be something you could explore more in the future?
For mass production of the discs a stamping machine would probably be able to produce more per hour. But at maker-scale CNC makes sense. Joe Pie did a video titled 'Pressure Turning' where he clamped a stack of aluminum foil to make really thin shims. Something similar should work with a milling machine, clamp a stack of sheet aluminum between some plywood held in a frame. Plywood will be sacrificial (scrap it after the batch is done), frame is reusable. Maybe possible to use multiple clamping setups and reuse the plywood or make some holding pieces from metal instead of plywood. First stage - cut out the center while clamping down on the top from the side. Second stage - base has a mandrel extending up that the top holding piece is bolted to , and the top holding piece is a thick disk the same diameter of the discs being produced. Second stage top holding piece would also have holes matching the holes to be cut in the disks. Also need a notch in the mandrel and a small protrusion in the center hole of the top holding piece, for angular alignment of the holes
@frontiervirtcharter Yea, I was more interested in how they did cnc in such fragile materials. I know it's not the most efficient way to do this, but it's still interesting
A mesmerizing journey into Tesla’s visionary mind! The bladeless turbine, a testament to his genius, dances with fluid dynamics and whispers secrets of energy transformation. Thank you for sharing this captivating exploration!
I'm quite impressed. I didn't think you could harness that much power from a unit that size. I've always wanted to build one of these, but I considered it a toy. I think i could actually build a vehicle apu out of something like this...
hey thanks for commenting. 🙏❤️🔥 I really appreciate the love and support. So just to be clear I do have a degree in physics and many years of working with industrial machines. And now I don’t want to discourage you but I need to be abundantly clear though that sadly, these are not toys. They are VERY dangerous if not designed or handled properly. I do not advise anyone who doesn’t already have a background in mech engineering/physics etc. to attempt to make one of them on their own. If you wouldn’t feel comfortable taking apart a jet engine and putting it back together and know that it would work properly again then I would think twice about taking on this endeavor. That being said. If you would like to start I would suggest by consuming as many mechanical engineering class videos as you can on TH-cam. Learn all the thermodynamics behind steam and gas turbines. Specifically for Tesla turbines it requires a great deal more chemistry due to the Tesla turbine operating on molecular viscous adhesive forces between the fluid and discs and not in mechanical collisions with the blades like traditional blades turbine. So making sure to have the right surface treatments for the proper motive fluid is very important too. “Don’t French fry when you’re supposed to pizza or you’re gonna have a bad time.”
I also have a degree in physics and other things... I'm curious as to why you're not using air bearings in your design. They're pretty easy to build and implement. In addition, you can use your Tesla turbine as a pump to pressurize them thereby eliminating the need for a secondary system. Once the system reaches its static equilibrium pressure it won't bleed off much more additional energy and certainly less than your cooled bearings.
Typically, if you increase the diameter of the disk, you'll get a lower max rpm, but a bit more torque. increaseing the thickness of the disk wouldn't be as helpful, as its just more mass for the fluid to pull, and less surface area.
@@beaverbear9157 thats not what he is saying he is saying make some of them small and some of them larger or maybe 25% small 10% medium and 65% large i think what he is getting at is you may have better effeciency as the smaller disks woiuld help it achieve the better torque and still have a more power. as for rpms it doesnt matteer what size the disc is you either have more torque or more power the rpms will be the same what do you think the discs would actually gain a higher rpm because of diameter? no my friend it has more to do with mass of the object so you would achieve higher rpms becuase you get to use more of the fuel as its lighter and easier to spin. diameter has nothing to do with what the rpms achieved would be.
@@petejones6827 hey thanks for the comment but that’s not exactly accurate. The torque on the discs is proportional to the square of the difference in the fluid speed and the disc speed and the surface area but inversely proportional to the disc spacing. So the disc tip speed is the important factor here. For any given fluid supply in, the nozzle will have a max fluid velocity. So the turbine disc tips will have a max speed set at that fluid speed irrelevant of radius, for a given nozzle. Now if you keep the tip speed the same but increase the radius the RPM decreases. And if you keep the same tip speed but decrease the radius, the rpm increases. Listen to what Tesla says in the patent even, “When apparatus of the kind described is employed for the transmission of power certain departures from similarity between transmitter and receiver are necessary for securing the best results. It is evident that, when transmitting power from one shaft to another by such machines, any desired ratio between the speeds of rotation may be obtained by a proper selection of the diameters of the disks, or by suitably staging the transmitter, the receiver or both.” -Nikola Tesla I hope this helps clear things up.
The small steam engine looked very cool! I think it would be cool to see how you would design a steam engine. Like maximizing for coolness or efficiency!
I’d love to see you make your own wind tunnel and maybe 3D print airfoils for testing! Or see the difference between different wind generators used in a wind tunnel like a blameless fan and a turning engine or the ionic engine and what effect they have on an airfoil
I think an interesting field to explore is plasma jet engines or magnetoplasmadynamic engines. An interesting topic from an educational perspective is in what way they are different from ion propulsion which you've covered before.
Wondering if this format could be applied to sea currents or be an upgrade to the current turbine systems in dams today? The Di Pietro compressed air turbine is also an impressive design.
Brilliant video, so cool seeing Nikolas inventions being tested. I was thinking you could do a video of the different types of stirling engines, which types would be the best for power generation (propane burner)
I'm subbed to your channel. At first I thought enginnering was difficult. You definitely made it easier for me and a lot of other people. Here's a video idea/ theme. "Engineering Marvels: Unraveling the Secrets of Cutting-Edge Tech and Physics"
Very cool video! I'd love to see this setup with a steam input. Relying on compressed air isn't the best idea for using the engine in the case of blackouts. Being able to go off-grid by using steam or gravity-fed water would be interesting to see!
Hey thank you for your insightful comment and genuine curiosity! It's a great opportunity to delve deeper into the potential real-world applications of the Tesla turbine and to clear up some misconceptions. First and foremost, in terms of using high pressure, low temp gases in actual generator capacities, Compressed Air Energy Storage (CAES) and Liquid Air/Cryogenic Energy Storage (LAES/CES) are very viable solutions, and they're being employed at industrial scales as we speak. When we look at how engines function, they typically compress air, heat it, and then expand it. Most gas turbines and turbojet engines possess a compressor, operating on what's known as the Brayton cycle. For those unfamiliar, the Brayton cycle comprises three main processes: compression of the air, combustion (where heat is added), and then expansion of the air. If we're talking about steam systems, only heat needs to be added to vaporize the fluid. Systems like ocean thermal energy conversion (OTEC) can vaporize steam, or even function in an organic Rankine cycle, at significantly reduced temperatures. Tesla's improved turbine patent GB 186,083 is particularly noteworthy here. It cleverly uses heat from the turbine exhaust to generate steam. This steam then cools the combustion jet before it enters the turbine, thus significantly reducing the compressed needs typical of most gas turbines. While regular gas turbines require an air-fuel mix in the range of 100:1 to 200:1, thanks to this innovative approach, Tesla's patent slashes the load that the compressor puts on the shaft, making it efficient even with stoichiometric mixtures around 15:1. Moreover, Tesla's patent GB 186,084 combines combustion and steam turbine functionality, eliminating the need for a compressor altogether. Our current tests with the Tesla turbine aim to establish baselines. We've already achieved impressive results with the 10in diameter TesTur- 6.22ft-Ibs of torque at 4150rpm and over 4.25kW between 6000-12,000 rpm, while maintaining relatively low pressures at the nozzle. It's crucial to understand that, counterintuitively, the viscosity of gases actually increases with temperature. This means that as we hike up the temperatures to combustion levels, not only do we anticipate a boost in thermodynamic efficiency but also a leap in the TesTur's isentropic efficiency, thanks to reduced slip caused by the heightened viscosity. Our endgame at TesTur Energy is all about energy independence. We're passionate about tapping into underutilized energy sources and stores, such as biomass, solar thermal, geothermal, and even unconventional fuels with high particulate content. The ultimate goal? To harness these energy stores with systems that can manage multiphase fluid flows, ensuring longevity and efficiency.
Additionally we have a full closed loop steam system for the turbine that is about to get used for testing it in the vacuum steam conditions. Already showing 150-300watts out with the inlet steam at 65-70°c at -10inHg vacuum pressure and the turbine exhaust/condenser at 55-60°c at -22inHg vacuum 🤭 Just imagine what will happen when we actually use some real heat. 🦾🔥🤓👨🔬
Tesla is so misunderstood even for today’s times im glad you guys are putting in the effort to show his work. My favorite Tesla invention is the valve. Keep up the good work
I think it would be a neat experiment to use your instant steam generation project in conjunction with this turbine to drive something. The Hydrogen Peroxide steam generation could provide instant steam to run the turbine, and the turbine could drive something else, like maybe a ducted fan, or stepped way down to run something like a go kart/ powered skateboard. Think that would be pretty cool.
they say there's a lot of untapped potential in grid water pipes, it'd be cool to see an idea to integrate this with a pipe fitting and flow water through it at normal house pipe water pressures to see how much power it can generate. i know some cities utilize the pipe pressure of the water grid already, just imagine the potential.
it's a TANSTAAFL situation, the energy abstracted from water flowing in a pipe has to come from somewhere which is often a pumping station. Having said that if you live somewhere with an unmetered water supply it might be economic on a personal level to generate your own power by wasting a few thousand gallons of water a day.
@@Steve_Coates I actually have unmetered water in a urban area (the hose water is unmetered, but the house water is metered) but I don't think I'd feel very good dumping perfectly good water out on a moral level.
Yo can you make your own superconductors? By now you've probably heard of the report about the new superconductors and I think it would be really cool if you made it yourself, as well as other superconductors. I wanna have my own lab someday and watching your videos inspire and motivate me to keep on learning how to make stuff myself, like using Blender and Python and all that. Yes I don't know what I'm doing. I just want to make new things.
I would love to see you build a giant Tesla coil that will actually work. I think that you can do it and made Teslas dream of wireless energy come true!!
An insanely popular (and INCREDIBLY useful; note how the news such as on Zerohedge is picking up the topic:) follow-up video would be building a biogas reactor/digester that integrates this with a small boiler. Thank you for sharing this! I was starting myself on this Tesla Turbine technology and this just shortcut'd my efforts tremendously!
Hey Integza, a possible theme for a future video could be powering an RC car with a tesla turbine and a rocket providing the air pressure! Great video and amazing channel. Always interesting and new content!
Idea for a future video, build a "1 Stroke" INNengine next?! I am sure you will come up with some crazy Inegza spin on this cool (and weird) new engine. Or experiment with running it on hydrogen as the manufacturer suggests this as a development idea? It's shown in this video from driving 4 answers th-cam.com/video/9I0_3qFmPUM/w-d-xo.html I mean, sure, it's actually a 2-stroke as even the creators explain, but it's a 2-stroke without all of the normal drawbacks of a 2-stroke.
it would be really great if you could design and build the small size steam engine that would run the turbine. there is none that i know of on the market to fit this bill. i hope to see that in the future. great job as always!
The immediate brilliance of the fluid moving closer to the center of rotation as it slows down from imparting energy to the disc, thereby moving to a slower moving portion of the disc as it slows down, is remarkable. Less slippage. More efficiency.
Hi all, as a suggestion, demonstrate solar boiler with Fresnel lens (less than $2) boiling (low pressure in boiler using tesla pump on both sides of turbine) pump water, with steam injector at pump outlet (return steam, vapor or water to boiler). also send output of boiler to storage (use aircret or aerogel for isolation); now you have seasonal storage turbine runs non stop, build two for zero fault tolerance (there cheap). If one fails use the other while repairs are made. Runs forever as hours of sun light provides weeks of energy to run the turbine without fuel cost, now pump water from oceans across deserts or any where water is needed (as system produces distilled water), and get green hydrogen and electricty free!
Awesome video! I think a really cool idea for a video would be an in depth on how to go about the patenting process for any of the creative minds that you inspiring. 😊

Thank you so much ! 😁
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?
Thats a problem with all turbines its why wind generators have breaks on them to stop them spinning in high winds
600 likes in 20 minutes?? xD
What emerald said, they all have limits. I’m sure the physicist took everything into consideration, but I like how you think :)
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.
One way you could look at it, the tesla turbine had a larger surface area per blade vs a general turbine
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
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.
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
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.
@@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.
Stoked you are helping Charlie out with a platform. Been following his progress on Instagram for awhile. Props to both of you!
Hey much love! Thanks for coming along on this journey with me! ❤️🔥🙏🦾
@@CharlieSolis Same here! I've been trying to make him aware of your content for a while. Did one of you reach out to the other or did a comment lead to the connection?
Honestly, as a theme for the channel, I would be fine just testing a bunch of parameters of this engine with Charlie. I'm not an engineer myself, but I imagine that there's a lot of R&D still left in this thing that many of us would be fascinated to see in a followup video or three. Thanks for making a video on this!

Will you be uploading an LTX video?
Great video it was very cool and i hope you keep making videos. Maybe try making an Ram jet or a scram jet. That would be cool.
When is the moustache coming back?🤣
Suggestion: Easy to print wind turbine that can actually charge a reasonably powerful battery (such as a car battery), that can be mounted to a motorhome or a stationary car?
And his comment was never heard from again
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.
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
With a wind tunnel to supply air so it runs while you’re driving down the road. Like an alternator
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
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.
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.
how about attaching an evacuated thermal tube to get steam from solar energy? maybe get a couple of them and make a steam module?
@@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.
@@ItsMeArda The problem with using salt water isn't that it damages turbines, the problem is that it damages the boilers.
@@francissmithson398 I think the problem is getting the water pressurised. You will have to use some sort of heat to pressurise your fluid.
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! 🤓

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.
imagine when they pump plasma so that magnetic field modifies viscosity. how many electronvolts plasma can reach beeing cold. when it makes enormous pressure but low temperatute plasma is it possible.
@@CharlieSolissorry not read all of it … but came across the too much space free air flow section … why not using a hard disk drive and modify it ? There is as little as nearly no space left between the platters so maybe orientate on that knowledge ?
@@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.
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!
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.
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. :)
What a brilliant channel and video. Without guys like you and the creator in the video, the Telsa turbine would have been consigned to the bin after a brief look. The fact he took a deeper look and got it to work when others would have gave up is fantastic. How many more of Tesla's ideas need a fresh look with an open mind?
Thank you my friend 😁

I’m glad you featured Charlie Solis and his work. I’ve been following him for years. He is a national treasure. I hope you can do follow up with his cryophorus, or his plasma jets.
Thanks for showcasing really fascinating engineers working out of their garages, the maker community is so dang wholesome!
Loving all the scale builds on uncommon mechanisms! Have you considered doing a video on the Sarich orbital engine? Was prototyped in the 70’s, would be cool to see one built for compressed air! Apparently even Wankel looked at the piston motion.
Your channel should be in the millions the quality of your videos is just amazing. thank you for all your time and effort.
can you run this with a rocket? and wouldnt it be more efficient to run this with water? Tomatos are disgusting !
Why do you think that? For me its not intuitive for water to be better? Well it might cool the disk which might reduce the expansion, but just a thought tho
@@vyvyyv8vohvgu77 I think it sticks better to the surface because of its higher viscocity so more energy is convertet into motion. But wouldnt it be interesting too, to try this with Steam
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
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.

Long time subscriber, first time poster. Your channel has got to be one oe the best ! Not only do you show how you came about the idea of testing a theory BUT, also the hurdles you encounter, what you did to over come them AND, your failures. It has long been that a smart man is one who learns from his failures and mistakes. You have exemplified this to its maximum. THANK YOU Ssooo much for all of your work. PLEASE DO NOT stop ! 😊😊😊😊😊
Love the video, I'm 27 year old blue collar worker(plumber) working on an invention! Your videos are very helpful. Would be dope to see a video on the complexity of treating water 💧
It's really great to see you going from just plastic models to real time recreations.
Use the Tesla turbine to display mechanical torque by using it to lift, move, or drive something. Amazing content keep up the good work!
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. :)
Also comparing it to other turbines that he has!
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.
@@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! 🤓
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!
Not only makers should help eachother, we all should!
Love this video man, im in extacy for seeing someone take Tesla his genius inventions, and evolving it so it fits more in the day to day life
Keep on doing the great work you do man, youre one of the few channels that, when i see a new video, i emmediatly click on it!
When you understand how it works with steam your mind will be truly blown. It functions as a condenser, extracting almost all of the energy before it escapes.
As a woodworker please look into how dangerous the table saw cross cut technique at 9:54 is. You’re a smart guy Charlie, the world needs you in one piece.
Yeah, as someone who has had wood kickback at me with luckily no injuries... that shot made me shudder. Didn't see a riving knife on the blade either, but I could be wrong.
Push stick. You can download a print.
Curious to hear the longevity of a unit. I realize Charlie isn't building them for that at this moment but would be great to see. Even "can we run this for [x] hours straight at 20psi" with good data monitoring. Hopefully he starts raising money to make it work :)
Hey thanks for the comment! ❤️🔥🙏🦾👨🔬🤓
We’re working on the residential closed loop steam Combined Heat and Power (CHP) system right right now in fact to be able to do endurance tests next! Just finishing up the hot water supply circuit for the boiler side and it’s go time!
Stay tuned!
Again thanks for the love!
@@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.
@@CharlieSolis, if you had 50kg of water at nearly 100C and boiled all of it, that would take approximately 113,000kJ of energy. How much of that energy could be recaptured by this turbine?
@@kevinbuiiedAs far as efficiency goes… (mind you this is a copy pasta 🍝 so it’s a bit long but it’s worth the read. There will be 2 parts the first longer than the second.) …My 2650watt electrical load run came in with a very low ball calculation of 40% isentropic efficiency.

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.

The reason why Nikola Tesla never made the Tesla turbine mainstream was because it was literally so efficient that the materials at the time would have ripped apart from the speeds it reached
Here's my video idea! It would be expensive but I think testing different materials and surface finishes on the disks could pull a non-insignificant amount of additional power out of the generator, I'd start the surface finish tests on the cheapest material if it were me lol.
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.
@@poipoi300 I never even thought about optimization across multiple platforms, I'm absolutely sure different finishes would result in higher or lower torque in different flow or environmental conditions even within the same flywheel. I could never do it but I will sit and watch a 30+ min. Video on it and smash that like button lol
@@devonmcnealy8900 Oh I wasn't thinking of different environmental conditions, but yeah I assume you could totally take advantage of that. Say your fluid is full of heavy particulate, it might be good to have small grooves to catch their inertia before spitting them back out.
You've had some pretty awesome videos in the past and this is definitely one of the top ones for me. Pretty cool!
As someone who has been involved in cutting edge technology for over 30 years when it comes to process control, I love to see great new uses for existing tech and also new ideas. I tip my hat to you sir, I have spent the last 3 hours watching your videos. Your habit of creating videos that blow our minds is a gift. Please keep it up.
The man had a pocket vibrator that could shake whole buildings. The turbine was hardly Tesla's best invention but that's a matter opinion. Great video tho and how awesome it is that made a working model. Keep up the good work my dude...
I always enjoy your videos! I would love to see a head to head of all the different generators you have avaiable to see what has the best output potential for the longest period.
2:16 bro knew what he was doing
I think you should make a video exploring more solutions for at home manufacturing that will hopefully allow even more complexity in future builds.

The best part is at 7:00 minutes. A man standing proud of his work. (about 7:08)
This is literally re-engaging me in engineering! A video with your attempts on any types of wireless transmission of energy would be SO COOOL 0.0
newbie, he doesn't do wireless power. he's only an engine guy, and a bad one at that.
His videos and community posts on his TH-cam channel are a goldmine of info! He does have a few posts about wireless transmission of energy and a few videos - some of them may be on his Instagram too.
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.
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!
@@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.
Graphene thought is interesting although an aerogel demo would be funny af
@@CharlieSolis be careful not to unalive yourself with shots to the back of your head
@@vgnhdhewhy would that happen? If anything someone will steal his idea and profit from it, no assassinating needed.
While we are on steam power, I think it would be super cool if you could do a video on the Doble e 20. One of the absolute most interesting applications of steam engineering in my opinion.
video idea: make a mini generator to charge your phone using the blade-less turbine and some kind of steam source.
love your vids keep up the awesome work!
It's great to see more Nikola Tesla's inventions on your channel, really enjoyed it! I wonder if it would be possible to build a small car with this and some kind of boiler with steam.
Could use a giant tank of compressed air.
Man this inspires me to work on my solar steam boiler again. Something like this would be the perfect input for the steam that it makes
Dude! That sounds like such a sick project, passive energy projects r so dope
You should do a follow-up video with everyone that has won a 3D printer. You can ask what they have created with it and to allow them to talk about how the printer has helped them with their creative process.
With all the load sheading in south Africa you have given me hope to make myself one to keep watching your channel keep up the good work
For the 3d printer, I recommend a video as a follow up to how these turbines could be implemented in a real life scenario. How could it get natural energy?
I’d love to see a video about optimizing a hydrodynamic drive, using electromagnetic energy to drive a submersible. I’m sure there’s a lot of different variable you could test
This is really cool, but the thing that fascinated me the most was actually the way they did CNC on those thin pieces of aluminum. Would that be something you could explore more in the future?
For mass production of the discs a stamping machine would probably be able to produce more per hour. But at maker-scale CNC makes sense. Joe Pie did a video titled 'Pressure Turning' where he clamped a stack of aluminum foil to make really thin shims. Something similar should work with a milling machine, clamp a stack of sheet aluminum between some plywood held in a frame. Plywood will be sacrificial (scrap it after the batch is done), frame is reusable. Maybe possible to use multiple clamping setups and reuse the plywood or make some holding pieces from metal instead of plywood. First stage - cut out the center while clamping down on the top from the side. Second stage - base has a mandrel extending up that the top holding piece is bolted to , and the top holding piece is a thick disk the same diameter of the discs being produced. Second stage top holding piece would also have holes matching the holes to be cut in the disks. Also need a notch in the mandrel and a small protrusion in the center hole of the top holding piece, for angular alignment of the holes
@frontiervirtcharter Yea, I was more interested in how they did cnc in such fragile materials. I know it's not the most efficient way to do this, but it's still interesting
@@xXfzmusicXx Use a straight flute mill. A spiral flute will pull the material up and scrap every single one in the stack.
A mesmerizing journey into Tesla’s visionary mind! The bladeless turbine, a testament to his genius, dances with fluid dynamics and whispers secrets of energy transformation. Thank you for sharing this captivating exploration!
Great video
I think you can try putting one of your jet engines on arc plane and use it to drop tomatoes
Great idea
i agree
Awesome video, it's great to see Tesla's creations put into action.
I'm quite impressed. I didn't think you could harness that much power from a unit that size. I've always wanted to build one of these, but I considered it a toy. I think i could actually build a vehicle apu out of something like this...
hey thanks for commenting. 🙏❤️🔥 I really appreciate the love and support.
So just to be clear I do have a degree in physics and many years of working with industrial machines.
And now I don’t want to discourage you but I need to be abundantly clear though that sadly, these are not toys.
They are VERY dangerous if not designed or handled properly.
I do not advise anyone who doesn’t already have a background in mech engineering/physics etc. to attempt to make one of them on their own.
If you wouldn’t feel comfortable taking apart a jet engine and putting it back together and know that it would work properly again then I would think twice about taking on this endeavor.
That being said.
If you would like to start I would suggest by consuming as many mechanical engineering class videos as you can on TH-cam.
Learn all the thermodynamics behind steam and gas turbines.
Specifically for Tesla turbines it requires a great deal more chemistry due to the Tesla turbine operating on molecular viscous adhesive forces between the fluid and discs and not in mechanical collisions with the blades like traditional blades turbine.
So making sure to have the right surface treatments for the proper motive fluid is very important too. “Don’t French fry when you’re supposed to pizza or you’re gonna have a bad time.”
I also have a degree in physics and other things...
I'm curious as to why you're not using air bearings in your design. They're pretty easy to build and implement. In addition, you can use your Tesla turbine as a pump to pressurize them thereby eliminating the need for a secondary system. Once the system reaches its static equilibrium pressure it won't bleed off much more additional energy and certainly less than your cooled bearings.
Thank you so much for covering this.
Wow amazing video once again! 🔥🚀 Can't wait for your next video, how about exploring the science behind supersonic propulsion?
Pretty sure this guy is buying likes on his comments
He had the same comment when the video was 20 minutes old with 500 likes
What would happen if you were to alternate either the size of the disks or thickness? It would be interesting to see how it affects the output.
Typically, if you increase the diameter of the disk, you'll get a lower max rpm, but a bit more torque.
increaseing the thickness of the disk wouldn't be as helpful, as its just more mass for the fluid to pull, and less surface area.
@@beaverbear9157 thats not what he is saying he is saying make some of them small and some of them larger or maybe 25% small 10% medium and 65% large i think what he is getting at is you may have better effeciency as the smaller disks woiuld help it achieve the better torque and still have a more power. as for rpms it doesnt matteer what size the disc is you either have more torque or more power the rpms will be the same what do you think the discs would actually gain a higher rpm because of diameter? no my friend it has more to do with mass of the object so you would achieve higher rpms becuase you get to use more of the fuel as its lighter and easier to spin. diameter has nothing to do with what the rpms achieved would be.
@@petejones6827 hey thanks for the comment but that’s not exactly accurate.
The torque on the discs is proportional to the square of the difference in the fluid speed and the disc speed and the surface area but inversely proportional to the disc spacing.
So the disc tip speed is the important factor here.
For any given fluid supply in, the nozzle will have a max fluid velocity.
So the turbine disc tips will have a max speed set at that fluid speed irrelevant of radius, for a given nozzle.
Now if you keep the tip speed the same but increase the radius the RPM decreases.
And if you keep the same tip speed but decrease the radius, the rpm increases.
Listen to what Tesla says in the patent even,
“When apparatus of the kind described is employed for the transmission of power certain departures from similarity between transmitter and receiver are necessary for securing the best results. It is evident that, when transmitting power from one shaft to another by such machines, any desired ratio between the speeds of rotation may be obtained by a proper selection of the diameters of the disks, or by suitably staging the transmitter, the receiver or both.”
-Nikola Tesla
I hope this helps clear things up.
The small steam engine looked very cool! I think it would be cool to see how you would design a steam engine. Like maximizing for coolness or efficiency!
I'm sorry I haven't found this channel sooner, what a fantastic; presentation. there needs to be more of Tesla's ideas put into practice. THANK-YOU.
I’d love to see you make your own wind tunnel and maybe 3D print airfoils for testing! Or see the difference between different wind generators used in a wind tunnel like a blameless fan and a turning engine or the ionic engine and what effect they have on an airfoil
I think an interesting field to explore is plasma jet engines or magnetoplasmadynamic engines. An interesting topic from an educational perspective is in what way they are different from ion propulsion which you've covered before.
Wondering if this format could be applied to sea currents or be an upgrade to the current turbine systems in dams today?
The Di Pietro compressed air turbine is also an impressive design.
Brilliant video, so cool seeing Nikolas inventions being tested.
I was thinking you could do a video of the different types of stirling engines, which types would be the best for power generation (propane burner)
2:08 sees this.
*sighs*
Checks comments section.
I'm subbed to your channel. At first I thought enginnering was difficult. You definitely made it easier for me and a lot of other people. Here's a video idea/ theme. "Engineering Marvels: Unraveling the Secrets of Cutting-Edge Tech and Physics"
Very cool video! I'd love to see this setup with a steam input. Relying on compressed air isn't the best idea for using the engine in the case of blackouts. Being able to go off-grid by using steam or gravity-fed water would be interesting to see!
Hey thank you for your insightful comment and genuine curiosity!
It's a great opportunity to delve deeper into the potential real-world applications of the Tesla turbine and to clear up some misconceptions.
First and foremost, in terms of using high pressure, low temp gases in actual generator capacities, Compressed Air Energy Storage (CAES) and Liquid Air/Cryogenic Energy Storage (LAES/CES) are very viable solutions, and they're being employed at industrial scales as we speak.
When we look at how engines function, they typically compress air, heat it, and then expand it.
Most gas turbines and turbojet engines possess a compressor, operating on what's known as the Brayton cycle.
For those unfamiliar, the Brayton cycle comprises three main processes:
compression of the air, combustion (where heat is added), and then expansion of the air.
If we're talking about steam systems, only heat needs to be added to vaporize the fluid.
Systems like ocean thermal energy conversion (OTEC) can vaporize steam, or even function in an organic Rankine cycle, at significantly reduced temperatures.
Tesla's improved turbine patent GB 186,083 is particularly noteworthy here.
It cleverly uses heat from the turbine exhaust to generate steam.
This steam then cools the combustion jet before it enters the turbine, thus significantly reducing the compressed needs typical of most gas turbines.
While regular gas turbines require an air-fuel mix in the range of 100:1 to 200:1, thanks to this innovative approach, Tesla's patent slashes the load that the compressor puts on the shaft, making it efficient even with stoichiometric mixtures around 15:1.
Moreover, Tesla's patent GB 186,084 combines combustion and steam turbine functionality, eliminating the need for a compressor altogether.
Our current tests with the Tesla turbine aim to establish baselines.
We've already achieved impressive results with the 10in diameter TesTur- 6.22ft-Ibs of torque at 4150rpm and over 4.25kW between 6000-12,000 rpm, while maintaining relatively low pressures at the nozzle.
It's crucial to understand that, counterintuitively, the viscosity of gases actually increases with temperature.
This means that as we hike up the temperatures to combustion levels, not only do we anticipate a boost in thermodynamic efficiency but also a leap in the TesTur's isentropic efficiency, thanks to reduced slip caused by the heightened viscosity.
Our endgame at TesTur Energy is all about energy independence.
We're passionate about tapping into underutilized energy sources and stores, such as biomass, solar thermal, geothermal, and even unconventional fuels with high particulate content.
The ultimate goal?
To harness these energy stores with systems that can manage multiphase fluid flows, ensuring longevity and efficiency.
Additionally we have a full closed loop steam system for the turbine that is about to get used for testing it in the vacuum steam conditions. Already showing 150-300watts out with the inlet steam at 65-70°c at -10inHg vacuum pressure and the turbine exhaust/condenser at 55-60°c at -22inHg vacuum 🤭
Just imagine what will happen when we actually use some real heat. 🦾🔥🤓👨🔬
Tesla is so misunderstood even for today’s times im glad you guys are putting in the effort to show his work. My favorite Tesla invention is the valve. Keep up the good work
I would love to see you make a jet engine with the external chambers, like frank whittle's original one.
I think it would be a neat experiment to use your instant steam generation project in conjunction with this turbine to drive something. The Hydrogen Peroxide steam generation could provide instant steam to run the turbine, and the turbine could drive something else, like maybe a ducted fan, or stepped way down to run something like a go kart/ powered skateboard. Think that would be pretty cool.
they say there's a lot of untapped potential in grid water pipes, it'd be cool to see an idea to integrate this with a pipe fitting and flow water through it at normal house pipe water pressures to see how much power it can generate. i know some cities utilize the pipe pressure of the water grid already, just imagine the potential.
Or by using 24v water pump or replace it with permit magnet motor to generate votage just by running water!
it's a TANSTAAFL situation, the energy abstracted from water flowing in a pipe has to come from somewhere which is often a pumping station. Having said that if you live somewhere with an unmetered water supply it might be economic on a personal level to generate your own power by wasting a few thousand gallons of water a day.
@@Steve_Coates I actually have unmetered water in a urban area (the hose water is unmetered, but the house water is metered) but I don't think I'd feel very good dumping perfectly good water out on a moral level.
Video Idea: use Tesla Turbine to power a flywheel energy storage system
I would love to see a variation of your electric jet but spun by a steam turbine rather than an electric motor
Yo can you make your own superconductors? By now you've probably heard of the report about the new superconductors and I think it would be really cool if you made it yourself, as well as other superconductors. I wanna have my own lab someday and watching your videos inspire and motivate me to keep on learning how to make stuff myself, like using Blender and Python and all that. Yes I don't know what I'm doing. I just want to make new things.
I second this. 🙋♂️
Before you know it, you’ll know what you’re doing and be inspiring people yourself
Nobody has replicated the superconductor research yet
I don't think it's easy or cheap to make, its relatively straightforward but I think it has low yield and is slow
I would love to see you build a giant Tesla coil that will actually work. I think that you can do it and made Teslas dream of wireless energy come true!!
Bruh that would be awesome
Nikola Tesla would be so proud of you integza, I look up to your smarts and revolutionary ways you find to make things work.
i would love to see you build a plane or something like that using the bladeless turbine
Great video, first time i heard about this type of turbine!
Kinda similar to a video I saw, where someone made an RC plane using the Magnus effect.(Magnus is a great name lol)
Yeah, it is
Lol at 0:09 it looks like there's a dead rat in the turbine housing
An insanely popular (and INCREDIBLY useful; note how the news such as on Zerohedge is picking up the topic:) follow-up video would be building a biogas reactor/digester that integrates this with a small boiler. Thank you for sharing this! I was starting myself on this Tesla Turbine technology and this just shortcut'd my efforts tremendously!
Hey Integza, a possible theme for a future video could be powering an RC car with a tesla turbine and a rocket providing the air pressure! Great video and amazing channel. Always interesting and new content!
Yesssssssss
2:07 🤨📸
Idea for a future video, build a "1 Stroke" INNengine next?!
I am sure you will come up with some crazy Inegza spin on this cool (and weird) new engine. Or experiment with running it on hydrogen as the manufacturer suggests this as a development idea?
It's shown in this video from driving 4 answers th-cam.com/video/9I0_3qFmPUM/w-d-xo.html
I mean, sure, it's actually a 2-stroke as even the creators explain, but it's a 2-stroke without all of the normal drawbacks of a 2-stroke.
I think I saw that video a few weeks ago, it's a very interesting engine idea. Would be cool to see @Integza build one.
Would be cool to see Integza's spin on it!
I know the parsons family 1:36 . Honestly nicest people I've ever met
it would be really great if you could design and build the small size steam engine that would run the turbine. there is none that i know of on the market to fit this bill. i hope to see that in the future. great job as always!
🎉Free Onshape!!!! I wanted Onshape forever but didn't want to pay money!
The immediate brilliance of the fluid moving closer to the center of rotation as it slows down from imparting energy to the disc, thereby moving to a slower moving portion of the disc as it slows down, is remarkable. Less slippage. More efficiency.
Awesome. Tesla blows my mind every time I learn something new. Thanks for everything!
Suggestion, make a tomato processor including bladeless skinner and Steam precooker with jet engine baking.
Hi all, as a suggestion, demonstrate solar boiler with Fresnel lens (less than $2) boiling (low pressure in boiler using tesla pump on both sides of turbine) pump water, with steam injector at pump outlet (return steam, vapor or water to boiler). also send output of boiler to storage (use aircret or aerogel for isolation); now you have seasonal storage turbine runs non stop, build two for zero fault tolerance (there cheap). If one fails use the other while repairs are made. Runs forever as hours of sun light provides weeks of energy to run the turbine without fuel cost, now pump water from oceans across deserts or any where water is needed (as system produces distilled water), and get green hydrogen and electricty free!
Awesome video! I think a really cool idea for a video would be an in depth on how to go about the patenting process for any of the creative minds that you inspiring. 😊
New subscriber here! Love your Tesla videos, been binge watching them. As a fellow Tesla fan boy, I'd love to see you build and test his Radiant Energy Harvester!
This is freakin awesome and i hope to be able to buy one. Seems like a really cool guy. It was really nice of you to share his website. God bless
That Tesla turbine would work perfect paired with a compressed air battery! Great video, cheers
Incredibly knowledgeable video
