This is the last of the three part series of building a micro Tesla turbine. It was exteremely challenging just to make it spin at these speeds with almost no clearence from the end caps and the housing. It didn't perform as I was hoping, but in the future I plan to do some updates on this one to see its real potential. The biggest problem is the fact that I never managed to balance it properly as I do not own any equipment for that. It's performace would be different, especially if the output shaft was geared. For those who will ask why I used the faulhaber brushless dc motor as generator is because it's very smooth when rotated and the vibrations which was a lot from the turbine alone wouldn't increase.

81,000 rpm - damn. Johnny, i'm very grateful and proud to have discovered this video. Very very proud. Today is my birthday, i'm 56. I've worked on lathes in metalwork shops for years. Your video was beautiful to watch. The comments also made me happy. Thanks. I see it's 2 years later Johnny - hope all is well with you. As an electronic technician i've always loved Nikola Tesla's work. This video has made me so happy. All the best Johnny and everybody else. Thanks again.

At that scale, he should have no problem hitting 200 k RPM. At those speeds, the rotor is so sensitive to balance that it must be balanced by spin polishing. It's the only way. It would also probably work better if he used air bearings.

@leshreddur 2 жыл бұрын

You really made a great device from scratch and must give you my utmost respect. Job well done. 89k rpm at 50 psi is obscene fast. My shade tree advice would be, as far as balance goes, you need to do several things different. 1 weigh machined disc and spacer and they need to be very, very close to the same weight. Were talking 8 digits past the decimal point close, I say that because I saw you sand them by hand, use 5000 grit or higher and wet sand them with water. 2 no soft metals, use the strongest materials you can get your hands on so there is less flex, because at those high rpms, they will flex. 3 use a rectangular air inlet port to more evenly distribute the force to the disc's or they will definitely flex and create imbalance because most of the force is coming from the middle and right by the inlet, they are flexing and causing imbalance. 4 and probably everyone's biggest hurdle is don't have just one inlet, ideally, you want 4 to prevent parts flexing and causing harmonic imbalance. North, south, east and west. And because it's output is so high, you need 2 exhaust ports, again chasing that imbalance problem away. 5, you should try to make it a practical application. The idea was to turn heat into mechanical energy that could then be used to create electricity. I'm not crapping on you at all, what you did was magnificent. What I'm saying is you've made it very far, why not try and cross the finish line that Tesla didn't have the time or resources to try? To further your principal of your device, it needs to run on steam. Because in the long-run if you create a proper working model, we get free heat from the sun via heliostat farms. Where a field of parabolic mirrors shine the suns light to one tower and that light boils water and powers a steam turbine. Then you run off batteries at night. Normal turbines can only run at 80% efficiency, tesla turbines run at 97% efficiency but back then no one could make one big enough that it didn't destroy itself because of imbalance creating so much friction, it would get to hot and soft and explode. Tesla didn't have as good of machinery as you or access to titanium. Maybe they need lots of little tesla turbines and not one large one. A Tesla turbine doesn't start to reach 97% efficiency until they are going around 50k rpms, you've shattered that with a homemade, handmade device. If you come up with the balanced mechanical formula that can be replicated and you patent it, you'd change the world as we know it, you would have tesla turbines extracting energy from dams, powering airplanes, creating solar power. Who knows what else. Something to think about when trying to go to sleep at night. All the best.

There is one thing frustrating about these projects. Mechanically, they are beyond awesome, all the work required to craft such fine machinery. But the "97% efficiency" is PURE MOONSHINE. Tesla got 100HP "out of a hat" all right, but the amount of steam that "went into the hat" was insane. This is why bladed turbines are in common use. The problem is that it is difficult to measure the power input in the gas stream (you need pressure & volume flow-rate, & nobody measures flow rate). I would suspect that the efficiency of this is on the order of 5% TOPS, probably more like that of my model 1/8th scale steam engine: 1%. If 10W were coming out, more like 500W was going in. How do I know? ANY thermodynamic engine has an efficiency limited by the temperatures of the inlet & outlet streams. If this were fed with steam at 50PSIG, temperature is 150C or 423K. If exhaust is to atmosphere, exhaust temperature is 100C or 373K. Efficiency of PERFECT engine is (423-373)/423 = 18%. The problem with ANY turbine is that is doesn't work well until you get to megawatt output size. I once got 75W out of a turbine (a little larger then this one, but much crappier in fabrication & design), but it was consuming more steam than my 1/8th scale 10 wheeler boiler could put out continuously! By the way, DO NOT gear down the output to the generator. generator's output is proportional to the speed SQUARED. At 90KRPM, a small magnet chunk & a small coil will do it! (At these high speeds it is better to go "ironless" in the generator). The generator & the turbine should run on ONE set of bearings, spaced so the rotor is BETWEEN, not overhanging, the bearings, to keep the critical speed as high a possible. You should not hold this in hand while it is running! If it fails, you could be impaled by disk shrapnel bursting through the case.
