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...

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

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

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

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 :)

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

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

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!

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.

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.

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!

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

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!

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.

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