SinkScience #06 – Tesla CD Turbine Holiday Decision Maker
By
The Tesla CD Turbine is a little home-made turbine made from CD’s, CD spindle, supermagnets, and glue. This CD Turbine runs on faucet water pressure. The Decision Maker is a simple game spinner, magnetically-coupled to the CD Turbine by 2 neodymium magnets glued to the pointer. Turning on the faucet water pressure rotates the spinner. Turning off the faucet causes it to stop on one of the activities on the spinner card. Pretty simple. Kids love it! So do I, hehe. Watch as I take it for a spin … I always order magnets from: www.kjmagnetics.com For more pics, videos and info on how to build this Tesla CD Turbine see my instructables at www.instructables.com The Tesla CD Turbine website: www.cdturbine.com
Running demonstration of the water-pressure powered Tesla CD Turbine III and Magnetic Coupler, running smoothly and safely at up to 1000 rpm at the sink. The CD Turbine is made from recycled CD’s and neodymium magnets. In this video, the Magnetic Coupler is seen levitating in the magnetic field of the CD Turbine. This vividly shows the interaction between magnetic fields. Then, the Magnetic Coupler is engaged at speed with the CD Turbine. The magnetic clutching action is shown, as well as the self-centering effect of the coupler. Order neodymium super-magnets here: www.kjmagnetics.com The Tesla CD Turbine web site: www.cdturbine.com To learn how to build Tesla CD Turbines, visit my Instructables site at www.instructables.com Check out my best videos at HowCast, the How-to site: www.howcast.com

Free energy has been here all along ,But Elite controllers don’t want ppl to be free from the costs of energy,if you want a real Free energy Magnet Motor, get the blueprints at LT-MAGNET-MOTORdotCOM ,Join the energy revolution!

i get what you mean , like tesla coil fusion reactor , that would be so awesome

I agree that the two should be combined. One Tesla turbine could be used to generate the hydrogen, and with ceramic discs, another turbine could handle the heat of burning it.
I think the ultimate would be to have a hydrogen plasma based turbine, with magnetic fields involved. (see MT Keshe movies on radical new magnetic plasma theory at YouTube/watch?v=wtf5bp76ArE )

i just wonder actually and i am having a look at how big a tesla turbine would have to be to power a water electrolysis vat to make burning hydrogen , it would be an interesting concept if the two could be combined in some way ,

When I hooked up a heater motor in reverse as a generator, I was only able to get a couple of watts out of this CD turbine. Most of the power of the faucet water pressure was used to overcome the turning resistance of the generator.

lol , i don’t think Tesla had thought of that one , awesome though to see it working , how much voltage and current did you get from it ?

what a joke, get a life

Hehe, repel mode is when the like poles of the magnets are facing each other. So the magnets don’t stick and drag like in attract mode, but more push each other around instead.
Some of my other videos show a magnetic coupler, engaged with the turbine, that is always used in repel mode.
October 26th, 2011 at 1:26 am
What the fuck is repel mode?

I think the main point is that the great inventor Nikola Tesla developed a really cool Turbine about 100 years ago. Now, for under $40 anyone can build their own model Tesla CD turbine based on the same principles. And maybe even learn a few things about Tesla which they conveniently omitted from the history books.

What the fuck is the point of this whole stupid cd water turbine, i think it was a waste of time to what that
October 26th, 2011 at 2:40 am
no marnujesz tylko wodę dziwaku!!!
October 26th, 2011 at 3:34 am
hhaha you could go hit some golf balls in the dark at your neighbours house you dont like
October 26th, 2011 at 3:45 am
Have you thought about using some sort of low friction bearings versus the cd spacing plate as a bearing? It seems that friction kills the momentum. Friction and heat are the devil to a lot of ideas.
October 26th, 2011 at 4:28 am
arent you wasting a lot of water?

@RonRay
Thanks for recognizing the possibilities!
Now, imagine this idea running on fuel at high rpm, perhaps in a Tesla car as a range-extender /battery charger.
A high-efficiency vortex external combustion chamber that runs on any fuel including wood would be ideal.
October 26th, 2011 at 6:02 am
Whoa! That is so neat!
With a field that strong surrounding the case, I can imagine that with properly spaced copper coils (and wiring), you could generate a lot of current!
I’ve never seen anything like this before! … NEAT!

In all Tesla Turbines, the fluid (whether air or water or steam, etc) always travels in a spiral, rotating several times inside the case in smaller and smaller spirals, before exiting out the centre spindle or exhaust.
The discs rotate in the same direction as the inlet nozzle flow, just as you suggest. You can have two nozzles, one for each flow direction, and then reverse the turbine at will.
October 26th, 2011 at 7:26 am
When the water goes in does it travel around the CD case in a circular motion before it exits out the spindle? Do the disks always rotate in the same direction? If you had the water going in the left side would the CD’s rotate clockwise and if you had it go in the right side would they rotate counterclockwise?

@thaiboxerty
Lots of other fun videos, but nothing (yet!) on filtration. I have some ideas, though…;)
October 26th, 2011 at 8:50 am
Thats pretty impresive. Have you any videos on tesla homemade water filteration/distillation devices
October 26th, 2011 at 9:25 am
Good job! But i think you would use more water, than you will make eletricity (money talking)
October 26th, 2011 at 9:33 am
For a self-contained CD Turbine set-up using a recirculating pump in a bucket and solar energy to run it, see my video YouTube/watch?v=tIWPsckaiCw
October 26th, 2011 at 9:39 am
its cool, but u should figure out how to use water hydrolics to use the same water to spin the turbine…no waste of energy :}
October 26th, 2011 at 9:50 am
true, but you get no cool points.
October 26th, 2011 at 10:04 am
that attachment on top could work as a tire

Running a garden hose onto a bicycle rim demonstrates the same boundary-layer effect and adhesion of a fluid to a surface, that exists inside a Tesla Turbine. That is what makes it different than any other turbine in use in the world today.
I have simplified the Tesla disc turbine design by eliminating the shaft, bearings and seals, through using a magnetic coupling between turbine and accessories. I think that is a major engineering step forward and it’s something I pursue.
October 26th, 2011 at 11:04 am
I don’t understand what you’re trying to show here in this overly complicated set up.
I can achieve the same thing by turning a garden hose onto a free standing bicycle wheel.
October 26th, 2011 at 11:18 am
Since watching the first water test and then this one… have you gone back to the air design and looked at any potential loss of power through air gaps (like you had loss through the gaps with the original water test)?
October 26th, 2011 at 11:55 am
Yes, other materials can be used for the spacer magnets such as washers made from stainless or polycarbonate. They will have to be no more than 1/16 inch thick and 3/8 inch diameter.
The top drive magnets need to be used if you want to get useful work out of the turbine with a magnetic coupling, otherwise you must have a shaft, bearings, and seals.
October 26th, 2011 at 12:50 pm
Most of the CD’s I use are already scratched! They are glued together with crazy glue and magnet spacers.
However, it’s interesting to note that the real Tesla Turbine designs feature little or no wear on the discs from abrasion.
October 26th, 2011 at 1:31 pm
does that scratch the CDs in the turbine?
October 26th, 2011 at 2:20 pm
can we replace the magnets with other stuff ?????

Closed caption is a feature on Youtube that can be turned on by clicking on the arrow at the lower right corner of the video, then click on the CC symbol. It makes text show up on the screen so you can read what someone is saying, or what sounds are happening. It’s mostly for deaf folks, but it’s great for language translations, too.
It only works on videos that it is enabled on. I had to type in words and set it up.
October 26th, 2011 at 3:23 pm
What is closed caption?
October 26th, 2011 at 3:38 pm
Thank-you too.
SinkScience # 02, 03 and 04 are now available as Closed Captioned. (more to come!)
October 26th, 2011 at 4:26 pm

BIG THANK for set it up closed captioned in here video,,,
BRAVO,,,
thank
October 26th, 2011 at 5:17 pm
Closed Caption is now available for this video, and I will be working on my other videos as time permits. I will do SinkScience #02 next.
It was a bit of a learning curve, but thanks again for the idea.
October 26th, 2011 at 5:50 pm
