"who are you?" "i'm you but better"

Make a copy of the copy and make it better! 5 fins and less clearance !

“Can I copy your homework” “Yeah just change it so it doesn’t look the same”

My favorite part is when he says "someone make a copy. And I like it"

they had copied your design because you posted a TUTORIAL HOW TO MAKE ONE!

Greatest honor an engineer can receive: being copied :D

The amount of negative comments on this video is bizarre. Apparently people like to comment before watching the video, it takes him just over 45 seconds to say that he liked the design and he even included the smiley emote in his comment. Its obvious that he liked the improvement and seemed to be shocked to see something on the market that resembled a passed project of his.

Why is this comment section so full of butthurt angry people? Did you even watch the video?! He said he THINKS someone copied his design, there is NOTHING there that implies he's angry about it. He even said he *LIKES* the "copy" for crying out loud!

i love how you didn't go the negative route and actually liked that someone copied and improved upon it. way to go man. if only there were more people like you, science and tech would progress a lot faster.

2:55 you've been bamboozled

The best part of engineering is to be copied and see what others come up with which is really fascinating. not only you will know the flaws of the designs but you will also improve and develop it much more which in a way is like an endless competition. Cheers out to both of you guys you and the copy respectively.

this is why its good to share ideas because someone out there will always make improvements you overlooked

I appreciate your humility in sharing a similar product which performs better than yours! Do you plan on improving yours?

Didn't you copy the turbo and just made it micro?

When you put the two together I thought it was gonna take off in your hand, sounded awesome. 👍🏿👍🏿

If I ever get a metal milling machine I might have to make a copy for myself! Thank you for really showing the detail and providing measurements! I could have fudged it all but as an engineer I like to have a reference

Would both fit in my Honda

... It is not about "He who invents". It is about "He who patents it first."

Imitation is the ultimate form of flattery. 😊😊

imitation is the greatest form of flattery, personally it's an amazing design and i can see the practical uses for microturbines

Thats just how every air Turbine is desingned, even 20 years ago , but okay you are the inventor

Its hard to say its a copy since you have used basic specs from the 1800s, besides that enough difference between the two exits to claim completely different designs despite any similarities between the two. Claim coke is the copy of pepsi when other colas we're already in the market.

If someone copies your designs, be happy, because you inspired these people to produce something ... Many people would love to be doing these things, but they do not. Congratulations on your channel, your projects and your shared knowledge .. Great hug!

Its great how this guy isnt mad in the slightest how someone else just made a bigger version.

if you would have patented the design would you not get a cut form banggood then?

He linked to the copy in the description...It may be a copy, but he's most likely making money off of it... He also gives a coupon code... #AD

I designed a laser sighted Pool Cue and then found out someone had copied my idea a couple years earlier as it was already for sale before I even came up with a final design. I hate it it when people steal my ideas then go back in time to profit off them.

You should be proud that someone liked your design so much that they built one like it. Imitation is a form of flattery.

like you're the first one on earth who thought of this design...

It looks well made even if I prefer the look of yours with the pressed bearings plates. I guess they could be more secured in place with the screws. At least it is a nice copy.

Very modest of you to publish this, a rare move on KZfaq :-)

I love the fact you didn't get mad, you went all scientific and dissected it and compared it to your own. And then you concluded it was an improvement on yours. Well done. I don't understand the coments saying you're mad and knocking. By the way, that sound at the end where you connected them in series....how good was that!

No one copied you because it wasn't your design in the first place.

Yeah, looks like your fins also block more air inbetween passes of the blade. Like how the copy is rounded which applies a longer stream of air per fin pass. Cool stuff

Notice the rotor blade profiles are curved in opposite directions (relative to air flow) in the two turbine examples. This may be one reason for the significant performance variance.

Can you connect two of those via axis and make a mini turbocharger? ..like one turbine will be hot side, and the other one will be cold side, and put it on RC engine, would that be possible?

Copied? Looks more like schooled you.

Well, at first glance, it would appear that the designs have similarities but the one you describe as a copy does have additional improvements to the design. For instance, the housing is larger and the turbine is larger. The modifications to the new design also seem to increase performance of the turbine by about 13,000 RPM at 2 bar while not under load. The improvement to performance under load is significantly more impressive with an increase of 13,800 RPM (6,200 - 20,000) at 2 bar. Additionally, the rotor designs are similar but not exact as they seem to have optimized the design of the rotor blade to provide better RPM while under load. I love your channel and the work you do is amazing, there is no doubt about that. I must admit that sitting here late at night watching your channel, I often see what you have built and begin thinking of ways to utilize, adapt, or improve upon your creations. If you do not already, please go through the process of patenting your designs. There are situations when an invention can receive adequate patent protection with a utility patent and a design patent. If your invention has a unique structure/function (utility) coupled with unique ornamental features (design), then you should consider filing both a utility patent application and a design patent application. This can be a difficult situation and it is recommended that you speak with a patent attorney prior to choosing this path. Both design and utility patent applications will provide you with “patent pending“ while they are pending at the Patent Office. For the most part, the patents granted by the U.S. Patent and Trademark Office are for *improvements to existing products* or for innovations *similar to products already patented* and patents can also be granted for the successful miniaturization of an existing technology. Here is a great article that explains a lot about how the patent process works: www.ipwatchdog.com/2014/05/03/the-successful-inventor-patenting-improvements/id=49396/ As an aside, it speaks volumes about your character that you are cool with the new turbine. Keep up the good work.

He improved it. You should be proud. That's what open source is all about. Love this channel.

0:47 Atleast watch and get some context first...

3:32 sounds like a twin prop starter.

Emulation truly is the sincerest form of flattery. I'd be stoked about copycats. If someone somewhere would think it's worth it to reverse engineer my designs, and even improve on the performance somewhat, all the while selling it for dirt cheap prices, i'd be over the moon. This is awesome!

As long as you’re OK with it, then I guess it’s the ultimate form of flattery!

OOPS I'VE BEEN SEARCHING FOR THAT TOY PART

Imitation best form of flattery ;O)

I think that your attitude is wonderful and to be applauded. To have someone copy and improve on your hard work and for you to recognise it for what it is and also to like it, well, I could not respect you more. What a wonderful and refreshing attitude you have and if more people had your attitude, well, how much better would this world be. Thank you, you are to be congratulated to the highest degree

They say that it's the utimate and most wonderful compliment "to you" when someone copies your design. I'd be proud of having made such a beautiful little tubine and have someone copy it. They obviously saw the potential and beauty of your design that they decided to explore it a bit and make their own version of it. I love that little turbine and i know who made it too, JohnnyQ90. Happy science fellow designer.

I just see complaining in the comments.. He only said he thinks that someone used his design as inspiration and "copied" it. And he just compared the two. "Copy" is just a word.

Just a thought, did you have your impeller in the wrong way around as well?

This kind of turbine (with another turbine connected by the shafts) could be the basis of a pretty cool turbo design for maybe an rc nitro engine

You could use these to make a turbo system for a nitro engine. Of course, with the two-cycle engines you use in your other projects, having boost wouldn't really do much. It'd just blow right through the ports an out of the exhaust with the piston at bdc. You would need to use a 4-cycle nitro engine, but the only examples of those I've seen are for aero use and therefore don't have adequate cooling and aren't meant to run without a propeller. But it could totally be done. I'd LOVE to run a turbo setup on one of my airplanes...

He not only copied but improved it...

I think your turbine installed in opposite direction.

So awesome! Great video and sweet turbines! @3:37 it looks like the nut on the "copy" vibrates loose

I 'invented' the Bernoulli lifting surface for an aircraft I thought would take advantage of the surface area for armor. It was to shuttle troops. I abandoned the idea. Years later, I saw someone else using it in R/C aircraft. I felt so good someone used the idea, that I wanted to get all 'geeky' about it. They took that as a threat, "Sure you had that idea.". Here, that whole deal all I felt was smart because I had an idea that worked. You get pride involved in anything and it spoils it.

3:01 Third Reich beats Isle of Man

mini turbocharger?

They improved the design a little. Where did you get the copy? How much did it cost?

Wow, the product everyone hopes to get on wish... The knock off that's better then the original. The end covers bolted on is a nice added touch too. Giving a good natural mounting point and higher strength.

the guy who copied your made a video saying you copied him

I don't know if it's considered "clickbait, cuz' the title sounds like it's making a pretty serious accusation, but the video didn't really back up anything. :X

imitation is the most sincere form of flattery

Also angle between inlet and uotlet it is quite different. I think can do the difference, considering different number of elements on rotor.

Hello, what is the purpose of this turbine?

Doesn't the "original" have its rotor blades angled the wrong direction? Shouldn't it be "cupping" the air that is being pushing in?

Super awesome. What are some practical uses for these ?

You inspired him :) You should be happy that you made him do this.

You just copied what engineers designed a century ago!

Adoro esse canal 😍😍😍

Innovation, my friend. :D At least, the copy made improvements in terms of RPM. Be honored because you started the idea which leads to more room for improvements.

Nice video on the comparison - This micro business is fascinating

lol the rotor of the copy looks kind of like a swastika...

The copy looks a little better no offense its because its factory

I would like to see if you could connect the two of those together similar to the way a turbocharger is set up and add a combustion chamber and remove a bearing from the front but leaving a small opening so it can suck using some centrifical Force 2 send it to the combustion chamber and then you leave the back bearing open for Clear exhaust port thus a really small jet engine

i think he is glad that someone perfecting his craft

copy ? Turbine already exist many year

The copy looks better

thanks for sharing the good knowledge and i appreciate your effort mate.

MKaybe I missed the storefront but i'd be interested in buying one to play around and experiment with. I am an electrical engineer and solar-energy hobbyist playing with ultra-low voltage/energy harvesting robotics and circuit applications. This seems useful for a lot of stuff!

While you made a great turbine and I enjoyed your video building it, let's be honest, the basic design has been around for a very long time. So I'm not sure you can take credit for it being a copy.

New macbook cooler ;)

cool. i have always wanted a micro turbine for myself

Very Educational videos thank you sharing them publicly!

i mean, i can understand being upset, but they significantly improved on your design, and made it more widely available, and i think technological advances based upon transformative work of a pre-existing design ought to be encouraged.

Looking for 13B parts for my FC RX7

These things have been around since forever, one of my tutors at college showed me one from round about the seventies.

Looks like the impeller is a little improved over the first one with somewhat smaller clearances - guessing.

I know what you feel. I'm the one who invented the wheel...

its a trick guys for more views on the video which appears to have worked.

Them: can i copy your homework Johnny: NO! THEM:IDC LMAO

which device did you used to put air in that turbine?

That's like the person who invented the bicycle saying the person who invented the motorcycle copied his design...

Not much of a copy....

I remember compressed air power used in indoor and free flight models from the 70s,the were using a small piston and turbine motors to spin propellers. Your turbine may not be as original as you think

Remember "Ideas Are Bulletproof" they can only be modified but the idea will never vanished easily..

Its a Tesla Turbine and someone made a similar one, worlds smallest violin.

Dude never give up they can't copy your mind keep it up...

i use to make these when I was a kid, very common part. Good lesson in equidistant definition geometry. parts must measure relative to each other. btw your rotor is in backwards.

just to point out a flaw in the copied design, In that last test, outlet of one to the others inlet, the copies housing bolts were vibrating loose and visibly rotating. Not too comfortable with a 90,000 rpm core being held back by vibrating screws, especially in a notably vibrating motor
