Micro Tesla Turbine MK2 | Part3 | Finishing and Testing 

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.

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.

What I'd like most of all is for someone to jump from recreating to practical applications and I think you are one of the few minds that actually could...

This is literal gods work. And we watch it on the internet. Such an amazing time to be alive

I am retired after many in a so called profession. I have watched every minute of your work and I am spellbound

The work you put into this is just amazing. You didn't just make a working part. This is artistic work at its finest.

Being able to convert pressurized air into light is the essence of what makes engineering so great.

It's wonderful to see your work with so much attention to detail. Working on a 4-prong mechanical lathe with everything adjusted is only for differentiated professionals. I am a dentist, and I live in Brazil, in the city of Florianópolis. But I did a mechanical turning course in my teens and I miss them a lot. So seeing your work is inspiring

An absolutely beautiful piece of work, the clearance between the blades blew me away. I can't even imagine the number of hours that went into this (don't tell me, it'll just make me feel bad about my own level of dedication to my projects ;) )

Now I understand why you've not been uploading any videos for a while. Keep up the good work :)

Its ppl like your self that bring us to a new and ever growing future of clean and effective ways to live. Just Amazing!

As a mechanic in fine arts I'm very very impressed !! A masterpiece created by a master. I take a deep bow 👍🏻👏🏻👏🏻

Young man I think you will be a great engineer one day and change this world. You have the gift and ability. Great men endeavor to do good for the benefit of all!

congratulations, is a pleasure to see how you go through the whole process.

Disregard my comment from the last video, I see the testing is in part three. Phenomenal work. Very intricate and impressive.

The sound it makes (not the imbalanced portion) is simply incredible! Excellent work!

Very cool, your craftsmanship is inspiring :D

Love this video it amazes me every time. Yes I’ve watched it over and over again.

When you suspended it between the 2 magnets with the piece of glass, it made me so happy, I've never seen that before and its brilliant!

Incredible. What dedication and determination to make 5 of those rotor assemblies. Just wow. Fantastic work. BRAVO!

Respect to all the hard work and dedication that went into this!

Simply beautiful. I loved every minute of watching this. Fantastic job.

Such workmanship. Just mesmerizing to the max.

Just wow. I love lathe work and tolerances on miniature machines. Your vids are brilliant to say the very least. I built a tiny jet motor compressor using similar techniques and size as your rotor. I never was able to spin it with fuel, but I regularly use a vacuum cleaner to spool it up and the sound was incredible. I will now go and binge watch the other vids u made. Thanks for uploading this set of videos. I love you're work mate.

A Fascinating Project, Real Dedication, Nicely Done.

Very high quality, fantastic work

I'll say one thing Johnny, you demonstrate more patience than I will ever be able to muster. Nice work sir...

You are without question, a very tenacious engineer, and I truly admire your diligence .. .

I'm so glad you did not give up on it!

great job....and great perseverance...congratulations and , thanks for inspire & motivate other people

Wow, really incredible patience and engineering. It's amazing to see what can be done at home!

Oooohh I like these three videos very much, thank you. You are the moving parts guy for when non-moving parts won't suffice, many applications apply for quite some time, more so in robots and drones.

Awesome! So much work.. Your machining skills are incredible

Totally amazing!!! You are truly a master craftsman.

A beautiful work of art, engineering, machining and patience. Thank You

that was stupendous! one of the best times i've had watching a demo video. extremely high quality production as well. wow!

excellent job, i enjoyed all your presentation. This shows how people can achieve a perfect result with perseverance and diligence.

Wow. I'm impressed. A lot! Amazing perfect work!!!

These videos of yours are the BEST on the site. I can't stop thinking about ways to try to use this in my applications!

Someone please give this person a medal 👏👏👏 his work is really appreciative and I did subscribe and like.

You did this song justice, good job! :D

Many thanks for sharing your great job!

I love to see your work and this is what I wanted to see, ceramic bearings and an alternator! Brilliant design work and machining keep it up. I was a machinist prior to becoming disabled, so I'm living vicariously through you. I have so many ideas and suggestions of where I would like to see you go with this, but I am refraining. I'll wait in anticipation of your next video.

I love your channel. Your designs are executed extremely well, and even when they fail, they never fail to amuse me. Great job, I hope you figure out a solution. Never stop innovating.

im happy that you made this happend all this effort testing materials its just amazing to see end product of your hands congratulations stay awesome 😎

3:21 It sound just like VTEC Just Kicked In Yo!

i don't have the slightest idea how this works, but watching you make it through the three vids was mesmerizing. You are a great craftsman. great backing tracks too.

what do u do for living?, what did u major in? I dont know how I even got to this kind of videos but all these look so interesting, nice work!

obviously youre not married. Just kidding. fascinating group of videos. totally enjoyed the pursuit of perfection. Watching the lathe was mesmerizing. your video expertise and volume of background music was unparalleled. Wish more people on you tube would understand that. Thank you for an entertaining and brilliant show of craftsmanship.

This is the coolest thing I have ever seen anyone make! Thank you!

Anything done on that level of perfection is inspiring. I was carried away.

Re-design the housing and internal rotor so the exhaust vents on both sides. If you look at some centrifugal pumps they do this as well. It'll remove the lateral thrust loading from the flow going to only one side, as it'll be balanced out.

awsome vid really nice edeting and music like!

masterclass right there people....truly inspiring to watch engineering at its highest level...thankyou for sharing

Amazing innovation in the design! I've been watching your videos for a while and they just get better and better!

I love this video. the turbine, and the music is awesome. Cheers mate.

I was wondering if you had tried Dry Nitrogen instead of compressed air. The compressed air (unless it has been run through a drier)will contain moisture that might possibly be part of the imbalance problem. Just a thought.

INCREDIBLE! I absolutely love your craftsmanship!!!

love everything about this project, video, music, great job man!

wow...one fantastic video with a fantastic song(the fatrat-xenohenesis)

With speeds that high, a minute imbalance is enough to make the whole thing vibrate... a very delicate and hard build for sure.

Congratulations your patience & attention to detail are extremely hi level can’t wait to see what you make next 👍😊

You have skills that's for sure! Your concept, design through to fabrication is amazing. I'm hooked now :)

Wonderfull work ;)

Lots of thinking before going to sleep i bet

That was awsome. Couldn't stop watching. What a great series of videos.

You are a master! Watching the machining in the last vids was mesmerizing.. . Thanks!

Why am I seeing this only after 4 years? What is RU-vid algo doing?

I wonder if it could be used as a small turbo for my bike? ;-) Great work!

Your patience and commitment is outstanding.

Amazing project and great workmanship, very good art.

When I saw that rotor suspended in a magnetic field, my inner Jesse Pinkman got through (loudly so) great videos

well done, magnificent ! I wonder how can it be turned in a 5 to 10 KW wind powered source. It would be a great benefit for a lot of people all around the world, not mentioning the name of TESLA as legacy! However, laser cut would improve the titanic work you've done...

Keep up the videos man. You give me some inspiration every time I see a video.

man u are realy maniac. i could not made such small turbine even if i have all equipment. my nerves will stop me after 10 minutes !! good job man !!

Hey u showed make a website and sell these because I would totally get one, these are awesome, keep up the good work👍

Top 10 amigo

Very impressive project and....AND.... truly amazing videography ...... every detail well lighted and clear....WELL DONE!

Just amazing how you work and 5th generation is awesome!

Nice. Maybe try running the turbine in a vacuum box for a higher rpm? Since regular turbine blades have trouble operating pass the speed of sound(complexity).

Can it be used in high powered rc planes as a separate air compressor for especially for turbine engines

I love this precision! For what ever it is needed....I love it!

I am most impressed over the entire production. As I am not an expert on the turbine, I would think that a no load limit of 89k rpm on this tiny device is a SUCCESS. Thank you for the entertainment as well as the education.

Hey Johnny, have you ever had any catastrophic failures of your rotors/turbines?

At the risk of sounding arrogant, could the imbalance have been caused by finger grease?

WOW, what a credit to you for your engineering prowess..beautiful work..

Dude... ¡you´re an artist! - congratulations. It´s a pleasure see your work. Grettings from Argentina

You might have reached a limit on what your materials can withstand I believe your vibration issues are from material creep. To make a more balanced one you could use titanium or nickel superalloys to make the turbine this would limit the material creep

Ah sweet, a turbo for my Honda! 89,000 RPM? That'll crush Lambos no problem

Exceptional workmanship

Outstanding workmanship. Bravo!

Its really cool and innovative, but what function will it serve? What will it be used for?

This... is... beautiful... How much for one ?

Awesome build man! I was very entertained and learned a lot from watching you do this!

Found It just now I it’s absolutely awesome!!! Was definitely worth stopping everything else and watch all parts of it :D

the imbalanced rotor sounds way cooler tho ;)

Are Tesla turbines used at all in products or industry today?

Superb piece of engineering. I admire your tenacity!

I really enjoyed watching a natural born engineer at work. What a beautiful piece of work, despite the rotor imbalance.

Is it just me? I can't click on the videos in the outro
