CD TESLA TURBINE 2 VLOG MAKE A TESLA TURBINE OUT OF CD DVD

[josephdupont]

So what did you use as a spacer?

[brotherboy77]

talking, talking, talking............ you actually managed to make a video about making tesla turbine, without actually make it *lol*

[schbrachbolidsei]

And so what? Using energy to produce energy got to be a loss of efficiency!

[d3dreaper]

Holy self-destructing discs batman!!

[sshukri0]

How can I build one with a louder "jet turbine" sound?

[sharpshark2323]

I have an idea on a self generator machine, I need help geting the parts to put it together, im here looking for help, please let me know if u can help. It looks promising on paper,

[Guitardude1616]

dan do you think that if i put a tesla turbine in a go kart that it would work? i think the biggest problem would be with acceleration.

[floyd5666]

How could one use compressed air to turn permanent magnets? Would this work to make electrical excess? Would it be possible to gear up this process to refuel the compression? I hope this makes some sense.

[DarkoMFS]

@floyd5666 just attach it to a permanent magnet motor/generator and it will generate electricity. Its the same thing as putting magnets on the disks with coils around them. If you though you could make a perpetuum mobile machine, you're wrong. You can't generate more energy then you put into it. Btw if its air powered you would need to run a compressor, and compressors are quite inefficient machines, except for rotary screw compressors. Btw im a mechanical engineering student, fluid engineering.

[Eaglebird]

Measure RPM from the edge for an accurate reading. :)

[csjmiller]

when you make the real one you should sharpen the edges of the discs to allow more air flow inside to create a faster and more powerful turbine

[Matsutom]

So what they didnt tell in history class is that Tesla knew how to make free energy... What i want to know is. How can we build one at home that would supply power for a whole household. And what i also want to know is what happens to excess energy that is produced?

[Eaglebird]

@Matsutom You don't want one of these for home power, much less power generation at all. Tesla turbines are good for speed, not torque, and the losses you incur in switching speed for torque is worse than losses from a normal turbine or even a reciprocating engine.

[bootsinbed]

Very cool Demo!

Can we combine this technology with the fuel-less heater I've seen on youtube and make it go forever?

[gjtai]

Y esto que coño tiene que ver con Tesla?? Acaso este tio no sabia que si soplas aire a presion sobre una superficie plana esta se mueve?? En fin, de catetos esta lleno el mundo, y de cortos que los admiran tambien.

[Glem911]

Nikola Tesla patento esto en 1913. En ese entonces la eficiencia maxima de las turbinas de aspas era aproximadamente de 30%

Usando los principios de vizcosidad y de adherencia de los fluidos (ya sean gases o liquidos) para hacer girar esta turbina con mucha mas eficiencia que las demas de su tiempo.

Y probablemente incluso ahora, mas del 70% de la poblacion no sabe que si soplas aire a presion entre dos discos ligeramente separados puedas llegar a 12000 RPM o incluso mas.

[Glem911]

@gjtai

[WEBBY514MTL]

sounds like a car

[Tagz3339]

why not use free compressed air to drive it I can show you how to compress air for free

[autonymouse]

This isn't even close to the way a tesla turbine works! A true tesla turbine works with fluid adhesion (yeah, that includes gasses), the pressurized medium moves BETWEEN the blades and out the center. In this vid the air gets one small contact point with the disks and so is 99% wasted.

Look it up kiddies, it's way cooler than this! (100,000 rpm is possible with a real TT!)

[juggernautxtr]

@autonymouse

i'd say 9139 rpm is pretty damn good.more than enough to turn a alternator or generator .

[walkertongdee]

This is a simple demonstraion better than you can do you are just blowing hot air... Ps: dont insult me by calling me an kiddie you twit.

[Jackle61]

@autonymouse: He mentions this in the first thirty seconds of the video.

[cornsqueezins]

you should use a shield and safety goggles

[proverb311031]

you are luck my cousin put a CD in her computer that had a crack in it, and when she called me over to fix it all I found was dust, you could have hurt yourself bad dude!

[Patriotgal1]

Dan- you need Denise there- you aren't measuring the RPM's until it is ALREADY slowing down!! Y'all come out to my REAL Machine Shop, we'll destroy the planet!! (Accidentally, of course!) But, what fun we could have doing it!!

[Patriotgal1]

As a Pilot, I'm VERY familiar with "boundary layers"!! And a Tesla Turbine- ULTRA COOL!! ALWAYS wanted to build a BIG one!! Another great one, Dan!

[nathanel1313]

ok that's cool, but how do you use it in real world? I mean, you're not gonna power it by wind...

still, a great concept of using the cds

[beatthinker]

ok.. but application?

[zayres29]

how do the cds not fly apart?

[nakedtruther]

15 seconds in he says "we've glued 5 compact disks together".

[lieberman70]

Hi,

Could you let it run against a piece of whool at one side (180 degrees of a surface) and against a copper brush hardly touching it against the other side of a single disc?

Wire the copper brush to a copper ball. Place another but grounded copper ball close to it.

How big will the sparks get in inches? Or by placing a voltmeter between the balls, what does the reader say?

[copperhead228]

does it matter how many discs you have

[wendlo1]

I love the tesla turbine Idea. In the 70's there was a man in our area that made a tesla turbine but drilled holes in th plates by running an oil through it it made a lot of heat enough to heat his home with a small quarter horse oil pump on it. I would love to see more of the tesla turbine to see how it would work with refraction heat for water or oil to heat a home

[jmm1233]

i wonder if there was a way to fit the turbine as an engine for a electric car using a quick burst of air from some fans powered from the turbine itself , and as the car moves it bring in more air to power the turbine ,

[ragtime40]

its over 9000!!!!! thats fast

[dinmamma1336]

ITS OVER NINE THOUSAND!

[teslstirlputt]

Proof of concept? What concept, that if you aim a stream of compressed air at any object stuck on an axle it will turn?

The title is "Make a Tesla Turbine. Not "Spin Something with Air"

You could demo the only "proof of concept" in this video by spinning an English muffin on a pencil.

[77camosoul]

@teslstirlputt you are stupid on parade...

[teslstirlputt]

@77camosoul Perhaps I am. But I machined a real disk turbine 8 years ago from home poured castings, including machining the disks, milling proper disk ports, etc. You can aim a stream of air at the periphery anything on an axle and make it move. And yes, a heck of a lot faster than 8000 RPM with good bearings, small diameter, and reasonably low mass. That's not a Tesla disk turbine if the air exits the periphery of the disk instead of axially at the spindle. Back to the parade.....

[77camosoul]

@teslstirlputt So you admit your description of this is false? Not everything needs to be precision engineered. Of course it won't work as well, but that doesn't make it any less of an example.

[teslstirlputt]

@77camosoul Precision isn't the problem here. The Tesla concept is for gas spinning between two disks in a spiral towards the center, then exiting axially through center ports at the spindle and case.

The flow in the video above is along the disk periphery and past it radially. Basically demonstrating a crude frictional radial turbine. Like an undershot waterwheel.

A case and axial ports are what make a Tesla Turbine act very differently than the above example, and what was unique about it.

[DigGil1]

@teslstirlputt Do you think a simple cylinder can rotate so fast with air going around it?

[lunewhite]

Funny thing about CD rpm when me and a freind was messing with a computer we got the hard drive upto 13000 rpm the disc broke smashed out of the drive nearly blinding me and just missing my freinds head.Dont do this at home or at least wear protection and stay away from the direction of force.

[teslstirlputt]

This is merely a bunch of CD's spun by a jet on the periphery. The action of a Tesla turbine requires laminar adhesion to the disk walls -- you discussed this as the reason for eliminating spacers. However this requires that the exhaust exit at the center of the disk pack. Spinning these gaps the way you did tends to produce as much outward (pump) airflow effect as inward, actually negating any Tesla turbine effect or gap flow at all. You're just getting periphery impact flow.

[heftycat]

Did you black out at :30 seconds or something?

[IdahoViewing]

If you watched both vids he explains what you said and that this was just a proof of concept test.

[bingusLootruss]

If there's any chance it could be an effective component of a home power plant, I would bet $ that Mythbusters would intentionally make it _not_ work.

[yoyodude7407]

why do you say that?

[dontsend36]

This guy is not a genius. This video is not good. This is stupid.

[DabQc]

I saw a real engine like this in 1996. You have to find the right angle of the nosel attack to produce the maximum rotation. I think it was about 60 degrees.

[BOREDUMBAS]

Try bouncing a neodyme between 2 larger magnets using coils to throw it both ways & if your magnets are strong enough & you can set your system with enough power to throw the centre magnet HARD against the outer ones with efficient coils around the point where the magnetic field compresses at each end to pick-up that energy (Plus secondary coils around coils throwing the centre magnet) you're going to make a vibrator or perhaps something more...

[akumabito2008]

Would the concept also work in reverse? If you provided power to the shaft, could it pump and compress air - similarly to a jet engine?

[LMF5000]

yes it will work in reverse (there's a youtube video showing someone pumping cranberry juice with a "tesla pump" as they're called), but you'd get an air (or water) PUMP, not a jet engine. Not sure whether it will also COMPRESS air as well as PUMPING it though.

[truinfini]

it sounds plausible. we could take that to Mythbusters and see what they can do with it.

[mikhasya1976]

Mythbusters made by Masters of Money :((

Wake up!

[truinfini]

wheres the food? (WTF) does that mean?

[redyoshi1985]

I want to see the next one you make. where you complete the whole thing. When are you going to make the next one. its been almost a year...

[Bullettube]

Even Tesla realized the inefficiency of his turbine. You still have to supply the air, or steam, or gas to drive the discs,  which in turn drive something else. The answer of course, is why not use the primary source as your driver and bypass this turbine entirely?

[navy2kq]

"The turbine efficiency of the gas Tesla turbine is estimated to be above 60, reaching a maximum of 95 percent" even 50% efficiency at the time this turbine was proposed was enormous. The problem was not the efficiency but the intricate production process needed to produce massive perfectly flat platters but if you would build it, it would have the same efficiency or above the current tourbines at a still higher production cost

[Bullettube]

The keyword here is estimated. Even a modern car engine is close to 90%. You still have the issue with placing a useless motor in between your power source and your work.

[LMF5000]

because your primary source is for example superheated steam from a boiler or a nuclear reactor - i.e. not something you can use directly as your driver (which is where the turbine comes in)

[kevinstuartfr0st]

just one thing i was playing with a cd on the end of my hobby drill (before seeing these videos)and at 35,000 rpm it shattered and i did have my hand in front of face and was glad i did because it f ing hurt :)

[pinballrobbie]

Its a badly spelled Tesla! my bad

[vincent7520]

what is a tesla or tesler effect ????

[pinballrobbie]

this is rubbish,its just ordinary air friction impelling the rotors-no Tesler effect here.

[ParapaDrifter]

no doubt, what is this guy thinking? He could have just spun a block on a peg and shown just as much.

[ak2600]

niewiem o co mu zabardzo chodziło przeciesz tak działają szlifierki na powietrze ale powinni zrobic autka na powietrze z takim napedem

[theONEpbS]

i am very curious to know how you held the cds/dvds onto the shaft with out them breaking by being pinched and also there is a video on here somewhere that shows a guy using a HD platter and gets it working with simply his breath from a straw very good videos and nice info keep it up and please make a completed tesla turbine thank you very much for your time

[rantingone]

I would like to build a parabolic solar collector to turn water into steam, then pipe it directly to a tesla turbine. Since the tesla turbine does not use blades, i would think it would be much quieter. Do you know tesla's design works well with steam, or better with just compressed air?

thanks for the video!

[imikewillrockyou]

Except how are you going to generate any power from a CD Tesla turbine? Can't use steam the CDs couldn't take the heat.

[cameronnoremac1]

but by painting an extra layer on it and putting a reflector on it wont the rpm change from a normal cd\dvd?

[Ckevinh]

fail.

no tesla turbine here.

[O0XFOREVER0O]

lol im naked! n

[tomacco123]

Why haven't you shown the top speed of the tubine??

[OptimusPanzer]

Can a Tesla steam turbine achieve the same efficiency as the ones in use in modern steam power plant?

Both with comparable size and moment of inertia of course.

[jimbodepot]

I remember I did a biography on Nicolai Tesla in 8th grade. I was amazed on what I found out about him. Now every time I read about his inventions its like hearing about him for the first time. A True Genius.

[GREENPOWERSCIENCE]

Yes, he was way under credited for his amazing accomplishments. Before his time for sure.

[wjbombo]

I love what you're doing Dan! Keep it up!

I would like to see more on this project.

Have you made any further progress on this?

Thanks for you efforts!

[GREENPOWERSCIENCE]

Hi,

Thank you, I will have a video soon, trying to cover a lot and it is a bit of work:-) Thank you again.

[rendrageed]

ever seen cd fly apart at 23000 RPMs? its funny

[hoser4]

Dan,

CD-ROMs are safe up to about 15000 RPM (think of 52x CD-ROM drives!), so as long as you keep it around 12000 RPM or less, you're quite likely going to be safe.

Additionally, you'll find that if you drill out exhaust holes near the center shaft AND put it in a proper rotor housing, you'll find that you can extract FAR more work from the turbine.

I might like to suggest hooking your turbine up to your solar flash boiler -- I think it will run quite nicely!

[davidsaliba]

52x is not done by revs but bi reading multiple tracks at a go and disassembling the tracks in memory on the drive transparent to the OS. the dvd drives do not have enough motor energy to spin so fast. some hard drives spin up to 15000 though :-)

drilling holes will ruinb the balancing of the dvds and they will shatter at high rpm most likely. drilling the holes needs CNC prcision.

[dvgurjao]

davidsaliba,

What if we drilled small holes in the shaft?

[dvgurjao]

hoser,

I thought about that too. Could we make a Tesla turbine run well with just concentrated solar rays? How about the fluid? Should it be water? Or just air would do it?

[motosmiley]

You probably hear this all the time... but Dan is the MAN.

[GREENPOWERSCIENCE]

:-)

[TheSolarBloke]

Hi Dan, enjoyed the demo' and was wondering if using hard disk platters would be a safer thing to try. They are stronger and designed to spin faster, better balanced and not so risky.

Cheers

[GREENPOWERSCIENCE]

G'Day:-)

Yes, platters are a much better idea. I have a video taking an old HD apart with 8 platters and spaces. The only problem is, the spacers are too wide for air. The ridge on the DVD is perfect for air. I will try the HD PLATTERS with water. What do you think? Thank you GreenPowerScience

[ohmslaw111]

Make a perendev. You will get tons of comments.

[kd5txo]

might make an interesting vehicle drive system where the turbines are integrated into the hubs of the wheels. Just a thought.

[DancingSpiderman]

too much drag.

[BILLNYYE]

Does the air have to be traveling at 164 MPH as well like a standard impeller?

[GREENPOWERSCIENCE]

Like this no. In a fully functional Tesla Turbine sort of. Because this is open higher speeds are reached as the air flows across the smaller portion of the disks. This acts like a transmission gear with the outer being first and the innermost being 4th. On a conventional impeller the flow only reaches the outer area so the area that covers the most distance can only go as fast as the air or fluid flow. In a completed model I do not currently know the speed reduction across the innermost section

[GREENPOWERSCIENCE]

Ask MrfixitRick and see if he can help with a fully build model.

[hybridracers]

While Im interested in your videos. Im not sure why we spent 10+minutes on watching you mildly explain what it was you were building and then you playing with RPM measurements. Im going to do some research on the subject and see what I cant figure out

[GREENPOWERSCIENCE]

It is a starting point for a Tesla Turbine and testing the concept.

[JavaLessons]

You think this could be an alternative for windmills, where you shield one side ?

[GREENPOWERSCIENCE]

Very Good Idea. Maybe funnel the wind. May not have a practical use compared to other systems but...... it might be...Any ideas?

[vlpod]

Hi Dan. I've just recently stumbled across a company called Tesnic that uses Tesla turbine discs in the wind turbine they produce. They've also got some footage on youtube.

Best regards.

[boxa888]

also i found a british patent that does what you say, its like a funnel that spins the tesla turbine.

[JavaLessons]

Maybe this tech is something to combine with the solar tower principle, you know, solar heated 'greenhouse' with tower in the middle, where the air rises.

Keep it coming, Dan !

[wilmadan]

looking forward to see your program working on a large scale so that many poor people will benefit.

[MrfixitRick]

Excellent demo of the Tesla Turbine idea! As a builder of Tesla CD Turbines, I too was initially surprised by the rpm capabilities of the air-powered design. So much so that lately I've been sticking with my safer faucet-powered one instead!

[GREENPOWERSCIENCE]

Thank you Mr. Rick, You have an excellent youtube channel. Keep up the awesome videos. Love the pumpkin carving.

[ShinsengumiTaicho1]

I can't wait to see what this can do with a load on it!  Keep up the good work!

[jesslessthemess]

Hi Dan, Love it! You know you've inspired me...maybe i'll in turn, inspire you! I'm going to take my computer fan, which is brushless motor design, and replace the fins for a solid disk..like you've done...and see what kind of energy i can illicit with the air pressure. I was also thinking that some ceramic skateboard bearings will help reduce drag and increase your output. Thanks again!!

[GREENPOWERSCIENCE]

Thank you so much. Please post a video when you have it completed.

[USACitizenJames]

Great job! Awesome vids on your channel.

Have you thought about getting into HHO Generation for a project?

[GREENPOWERSCIENCE]

Yes, I have 3 stainless steel pipes in descending diameter. I plan on using the Neutral Plate design. I am hoping to run it into the air intake and see if it really boosts MPG or if it throws off the sensors. Have you tried it yet?

[USACitizenJames]

Not yet... but I have made a testing generator.

I'm firstly going to make the HHO cutting torch, but I see many people have made some interesting progress with their vehicles.

[RevolutionaryJam]

excuse my igonarance but what can this be used for?

[GREENPOWERSCIENCE]

GOOD QUESTION!!! This with CDs is really nothing more than a gadget as it cannot be used with any solar or heat source, only recycling old DVD and CDs I suppose. But it does illustrate the power of the Tesla design and the boundary layer effect, metal plates spaced similarly could harness steam. The question is, will the design out perform a standard turbine or is it just a gadget. I found a source of plates that are heat resistant and will work perfect. Future Video.

[RevolutionaryJam]

can you turn it into an energy device that will save you money and stop you being fucked by a buck by energy companies?

[GREENPOWERSCIENCE]

I am hoping to at least soften the blow.

[RevolutionaryJam]

hahhaah sweet i saw a great british video of a solar powered air heater on here, it's in my favourites if u wanna check it out
