SinkScience #03 - Tesla CD Turbine With Magnetic Balls

[minijimi]

Funny delayed reaction at the end...

[uniblab1000]

waste of money

[MrfixitRick]

@uniblab1000

I'll give you 100% of your money back.

[FiEctro]

The Cake is a Lie.

[MrfixitRick]

@FiEctro

What "Cake" do you refer to?

[csb04d]

@FiEctro LOL didn't expect to see a Portals reference here XD

[flashinmahcash]

imagine what rpm's you could get with a pressure washer...

[Sorenish]

It had a climactic ending. I also liked the plastic cake cover and cd/dvd spindle used for construction.

[sikomaggto]

Nerds!!

[RomeoReject23]

Dude, I would so not have put my face near those things. lol

[neezocrene]

the ending is chaotic..haha

luv it...;p

[Phacias]

Tesla turbine has magnetic balls! Oh my!

[MrfixitRick]

@Phacias

Tesla needed metal balls to put up with the crap he received a hundred years ago!

[Phacias]

@MrfixitRick That's right. A hundred years... Quite a long time, impressive, innit?

[railstoruin]

Auto Focus.....

[AnselmoFanZero]

I dont get it....

[MrfixitRick]

@AnselmoFanZero

The turbine has magnets on the discs that make the magnets in the bowl move.

[AnselmoFanZero]

Practical use?

[MrfixitRick]

@AnselmoFanZero

No practical use i know of, other than to demonstrate magnetic forces.

[WEBBY514MTL]

only if you could mace a perfect circle tube to hold the balls and make them travel really fast

[dhudson369]

i want to put a magnetic viewing card over that see what kind of fields its giving off

[Re4dSetH]

have you tried playing with a Rodin coil yet?

[MrfixitRick]

not yet, but perhaps soon! Any particular ideas?

[user9893]

Hey! wow I am so intrigued by this! I saw the other one where you had one ball and a glass bowl, and i thought it would be nice if you had more balls in it, but it would be even better if you would do one with different size balls with different magnetic intensities. I would love to see that! would the smaller ball revolve around the large ball while both is going around the glass... hmm you should do like at least 2 big and 2 small... can you do this for me please!?!!

[MrfixitRick]

Hehe, I've tried using different-sized magnets, but then they start sticking to each other. The bowl has to be at the correct height for each size ball, to repel each other of it's same size.

You seem really interested in magnetism, and I suggest that you try some of your own experiments. The homopolar motors are a great start, or maybe consider building a magnetic turbine!

[Penksimo]

too many balls involved ,, i don't like it

[brimstone555]

I'm not the backyard inventor I'd like to be, but that would mean the actual turbine would have conduct electricity like a multipoint rotating tesla coil?? wish you best of luck.. maybe that the perpetual engine no one can discover yet!!

[MrfixitRick]

The rotating multipoint Tesla coil is not such a bad idea. I hope to try experiments with it by using a high voltage spark to cause special implosion effects in the water that will power the turbine.

[brimstone555]

interesting 1!! gives me good idea for electric gap discharge... could be a useful component in future turbines??

[MrfixitRick]

I would like to experiment with a spark implosion process using the magnets to activate the spark.

[anfokg]

inside is vacuum?

[MrfixitRick]

No, the turbine uses household water pressure and is full of water. The magnetic balls are in the open air.

[anfokg]

rullets?

[MrfixitRick]

what are rullets?

[repeatedjellyfish]

One word, cool.

Science is cool. Keep up the experiments and keep posting the videos please.

Thanks.

[spydude007]

why dnt you both grow up....

you know these youtube arguments get you know where so build a bridge and get over it

[pyrorar]

wow....

do you not know the meaning of the word "safety" or what?

[MrfixitRick]

In the interest of mad science, I take risks so you don't have to. I often do wear my Tinfoil Safety Toque which has protected me so far.

[pyrorar]

I might be able to take that as sarcasm, if any of your other videos had any hint of proof that you aren't a complete moron to begin with...

but then I guess you get what you pay for... Nothing but a half baked homemade physicist with a severe complex for avoiding proper experimentation and safety techniques..

How about a bit of lateral thinking? Maybe some kind of actually interesting experiment, or use for this "motor" you've constructed out of your mothers kitchen faucet and old cds..?

lol

[MrfixitRick]

"Proper" experimentation? With CD's in a CD Case? Give me a break. Why don't you get away from the computer once in a while, and actually DO something instead of complaining!

Even though I lost my job, can't work and live in pain and complete poverty, I still put out, buddy. Have a look at my two dozen other CD Turbine videos first. Each is different and shows something special.

And I've never been hurt by any of my inventions.

[pyrorar]

Yeah I couldn't imagine how brass ball bearings spinning around at 3k rpm could pose ANY possible imminent threat to anyones health...

I'm the one whos crazy here. Right, gotcha.

[MrfixitRick]

1.) They are sphere magnets, not brass. Pay attention.

2.) It's 300 rpm, not 3000 rpm. Do you even bother to watch this movie before being so critical?

3.) You don't have a clue about what can or cannot hurt you. Always wear a helmet, would be my advice to you.

[pyrorar]

I'm not even going to bother trying to explain sarcasm to you, but lets break this down a bit shall we..?

Are you going to be thankful that they were only sphere magnets and not brass balls when they happen to break loose of your impressive protective "barrier" and lodge themselves into your retina?

That wasn't 300rpm, and again, does it matter?

I have a clue about what can possibly go wrong when working with machines under pressur and take precautions accordingly. You should try it sometime

[MrfixitRick]

I've been a full-time mechanic for 40 years, bub. I know a bit about working around machines.

You should try actually doing something with your hands instead of your head.

[pyrorar]

Why don't you get lit up and sit behind the wheel? Try streetracing some kids hanging around your local wal-mart parking lot.

Its completely safe bud. No one will get hurt

Until the day the inevitable happens and someone does. lol

But hey, what do I know? You've been a professional greasemonkey for how many years of your life now? What am I thinking even trying to comment on your practice and procedure?

Maybe for christmas this year your mother will buy you a starter science kit from toysRus

[DancingSpiderman]

Nice drum roll there

[projectsnowflake]

and your point?

[MrfixitRick]

I just wanted to see what would happen to magnetic balls attracted to the magnets of the turbine. I showed there are patterns in the rotation of the magnetic balls, which varies with rpm, and that six balls can be rotated simultaneously.

I also show a cheap magnetic Tesla Turbine that can run on faucet water pressure and can be used for a number of fun experiments. It is a shaft-less, seal-less, bearing-less disc turbine, with a magnetic drive coupling it to various attachments.

[Anothercoilgun]

Don't give Vegas no ideas :)

[MrfixitRick]

You mean like a glow in the dark Tesla Turbine Bingo Machine?

[Anothercoilgun]

No I mean like control of Roulette wheel.

[MrfixitRick]

I actually did an experiment, with a mini roulette wheel, and a magnetic ball on top of the turbine, but it wasn't fun enough for a movie.

[sobal79]

thats awesome dude!

pls make them fluorestic and switch off the light. cam from the back(no from the top)!

[vipersrules]

Where is the water going??

[MrfixitRick]

In this case, after leaving the centre exhaust of the turbine, the water goes into the sink and down the drain. My later CD turbines are on a re-circulating system, rather than drawing from the well.

[vipersrules]

Coool :D

I'm wondering if I should do one of these for my science fair project, don't wanna kill anyone though :D

[MrfixitRick]

For a really cool project, check out what my student, Rowan, did for the local Home-School Science Fair. See YouTube/watch?v=6kQiZoccoFU

[xCharbel]

I want to see these on the glass plate.. with much less resistance ... will they go backwards... ? They must...

[cheetawolf]

or maybe theyll bounce and shatter it

[SpeedMetal4635]

???

[MrfixitRick]

Could you be a little more specific about your question?

[RogerDodger69]

Magnetic vortices..... higher speeds require better balance. This rocks  (no pun intended :D )

[halosux4life]

just an idea.... if you make a turbine that can withstand extremely high rpms and use extreme compressed air like out of a scuba tank that is around 2800 psi you could make somthing interesting happen eh!?!

[MrfixitRick]

That something would be my Tesla Turbine-Assisted Bicycle idea!

High rpm carbon nanotube discs and a carbon fibre case would make a lightweight Tesla turbine capable of high power.

Great for short bursts to pass cars...or race motorcycles!!

[halosux4life]

haha sounds quite cool

[AHW214]

Do the metal balls jump because they cant keep up with the magnetic field of the super magnets, so instead of following the magnets every move the balls jump sections of the magnetic field to keep up with the magnets?

[MrfixitRick]

The magnetic balls tend to jump before any slippage of the magnetic field occurs. That is, they stay lined up with a corresponding magnet of the turbine.

The mag balls swing out with increased rpm, and the north/south relationship of the ball to the turbine can get partly flipped into repulsive mode, bouncing it temporarily.

Maybe. Could be just magic.

[airbear213]

i dont wanna sound stupid lol but whats the point of this all i can see is some magnetic balls bouncing around ???

[MrfixitRick]

The six magnets of the turbine under the bowl interact with the ball magnets in certain patterns depending on the speed of the rotating turbine magnets. I found some of the patterns fascinating to observe, as I am very interested in how magnetic fields behave. The experience I gathered here, led to other discoveries later, notably the reverse rotating ball effect.

[onthecuttingedge2005]

I'm not paying the water bill this time!

[MrfixitRick]

Hey, at 5 cents an hour for electricity for the well pump, it's the cheapest fun in town!

[henrjohw]

interesting

[MattyH101]

how efficient is the tesla turbine?

[MrfixitRick]

Tesla claimed the original Tesla disc turbine could achieve 98% or more efficiency. Most modern Tesla turbines are around 30 to 40 % efficient. That number may increase radically with new materials available soon.

My Tesla CD Turbine is more like 2% efficient. Using a CD cakebox and CD's is just not the most efficient way to go!

[ubtalking2jz]

just using water pressure... not purptual motion =(

[cadian14758]

is there any way to control the speed, e.g slowly stop the magnets from spinning, opposite to the start? or will they just group together like they did at the end. and how expensive are these magnetS?

[MrfixitRick]

The ball magnets can be slowly stopped without grouping, if done carefully.

The six 3/16 inch ball magnets are quite cheap at about 35 cents each, but the turbine magnets in this design work out to be about $50 altogether, between the spacer magnets and the top drive magnets.

[chronotyphoon]

yes i did enjoyed it, and wats funny to is that people think that you could link them to gether and make ur own energy,XD. (if u could ,XD, u would be rich becouse u would have a perpetulem mobile <-- prop not good english:P)

[dibbuck]

erm?

[MrfixitRick]

Could you formulate that question a little more exactly such that even I may understand it ?

[chronotyphoon]

HAHAHAHAHAHHAHAHAHAHHAHAHA too funny

[MrfixitRick]

Wow, you almost maxed out the Seven HAHA Limit for Youtube!! Glad you liked it, though.

[theultimatekoopa2]

There's a limit? HAHAHAHAHAHAHAHAHAHAHAHA

[microprophet]

Oh snap you go da AIDS

[kevinstuartfr0st]

hi good video,i know nothing but i wondered if you could put a strip magnet like on fridge doors around the edeg to stop the ball magnets from hitting the sides,like some others said i would like to see slow motion video,it seems as it the ball magnets brake away from the base magnets but not from its magnetic field,they seem to jump up and loop,

[joshuaharl]

whats the difference between this and a magnetic tumbler besides being water pressure driven? - Just curious...

[MrfixitRick]

The magnetic tumbler, or a magnetic stirrer, will generally have a rotating horizontal North-South bar magnet whereas the tesla CD Turbine uses 6 North-up magnets for it's magnetic field.

[disndat11]

Are neodymium that you mention same as NdFeB magnets?

I just ordered 120 pieces from China to mess around with.

Greetings from Iran

[MrfixitRick]

Those are the ones...congratulations on starting a new career!

You will have lots of fun...after you figure out how not to pinch fingers!!

[NickRoman]

That's kind of cool how the magnets jump around like that. I think it's mostly only interesting from a pure science perspective, which makes me also say that it would be nice to have a better camera setup to actually see it better, and a slow motion of course. So, you guys sell a lot of magnets? I would think so with all this youtube promotion.

[MrfixitRick]

For the best selection of neodymium supermagnets, I use K&J Magnetics. The link is found in the "more info" to the right >>>

[Vince878]

Looks fun. What's the thing with the water connection? Does the water pressure make it all move? How could you convert this into power and are there anymore in this series?

[MrfixitRick]

The device is what I call the Tesla CD Turbine. It uses CD discs that rotate from water pressure through a nozzle glued onto the side of the CD cakebox.

There are magnets glued to the discs and they create a rotating magnetic field which can do many things, including develop power.

Click on "more info" to the right>>>

There are links to my cdturbine website, as well as to my Instructables that describe step-by-step construction.

Check out my other videos in this series at Youtube/mrfixitrick

[eddiefreddie39]

That is really cool.

[MAllen7424]

That would be interesting to see with a slow motion camera!

[kadukov]

or with a strobo, a lot less expensive xD

[MrfixitRick]

Use the K&J Magnetics link posted in the "About This Video" to the right>>.

[warmingtone]

Again cool! You should see if you can develop a kind of casino or old time arcade game with this thing, maybe a lotto number extractor!

[MrfixitRick]

Good idea, perhaps in a steampunk look.

I do have SinkScience #06 which is a faucet-powered, random game spinner, "Holiday Decision Maker".

[ewmegoolies]

Hi ya Rick, just drop a CD under the magnets to smooth out the traveling surface.

[EasyQuest]

Where can I buy the cheapest n50 magnet?

Those really powerful ones that can crash fingers

[EasyQuest]

Where do you get these magnets?

[MrfixitRick]

There's a couple of sources I use. One is K&J Magnetics, and the other is Supermagnetman.

K&J has the best selection for the thin 1/32 inch spacer magnets between the turbine discs.

Do a Google search to get the site.

[EasyQuest]

is there any retail store that sell magnets?

[MrfixitRick]

Sometimes novelty shops sell them, and craft shops often have, say, 1/2 x 1/8 inch neodymium magnets which can be useful.

K&J is still the best for the thin spacer magnets, through the internet. You could use something else for the spacer magnets, and just put magnets on the top disc, to save money.

[TWISTYTWAT]

omg are they jumping

[MrfixitRick]

Well one jumped out at the end, but mostly they do this kinda cloverleaf pattern while staying on the surface of the bowl.

[outcast444]

have you ever tryed to put MagnaView Fluid on it too try and see what is happening?

[MrfixitRick]

I would like to try magnetic fluid.

[rozdani]

very cool!!

TESLA IS FUTURE!!

[MrfixitRick]

"Let the future tell the truth, and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I have really worked, is mine." ...Nicola Tesla

[AdminOnDuty]

Diamagnetic water, this is a great demonstration for those that understand the effects. LOL at the shear disruption there at the end. :)

[MoldytoasterVideo]

nice

you should do some more sink science

[MrfixitRick]

Thanks...there's seven so far. Only 93 more to go!

[surfertricker17]

That was intense. I love your videos. Ive been interested in Tesla for months. He's amazing. Your voice sounds like john hutchisons.

[MrfixitRick]

Keep up the interest in Tesla...it's worth a lifetime of study!

Also, I've just put up a new web site for things related to the CD Turbine. (just add dotcom after cdturbine)

[MrfixitRick]

So to sum up, this effect has nothing to do with the shape of the bowl. It works with any rotating ball magnet, singly or in a symmetric group. It even works the same underwater. Good observations ratthead. Thanks for your comments.

You should try this! You would be amazed and delighted with various effects.

[ratthedd]

[comment limit = 500 characters...] Also, what happened at the end of the video? Did the turbine start spinning faster than what the spherical magnets could keep up with in their track?

[MrfixitRick]

Although yes there is a track, magnets don't follow the track. (it's the same effect in a smooth bottom pyrex bowl only much louder!) They follow the corresponding magnet underneath in the turbine. That is, until I speeded up faster, the balls got a little more chaotic, and eventually connected with each other.

[MrfixitRick]

Have a look at my new SinkScience 07 video "Ball in a Bowl" for more observations on this weird effect.

[ratthedd]

I'm a bit confused: Is the track the sphere magnets are running in on an inclined plane? It looks like the spheres are running in a circular track near the bottom of the video frame, but when you move the camera view up, the spheres appear to trace a cardoid or even a multi-cardoid curve. Is that a trick of the light or is something funny happening with the magnets?
