The Making of the Tesla CD Turbine Prototype

The Making of the Tesla CD Turbine Prototype is the story of how the Tesla CD Turbine idea came into being.

It starts with the initial thought process (What if McGyver met Tesla...), then continues with the narrated assembly of the first crude prototype, using recycled CD's, cheap neodymium magnets, and dime store ice-cream scoop inlet.

And this thing actually works!

what the hell do you need to spin cds for

@cazz096

To me, the sound of music is a high-speed turbine. The Tesla Turbine is what the World's Greatest Inventor said was the greatest of all his inventions. I hope to reinvigorate interest in the Tesla Turbine through my videos.

Quick question:

This movie was made about four years ago. One of the points of making this cd stack was to try to use it to turn a turbine and create power -

How did that go, exactly? Has anyone at all defied the laws of thermodynamics just yet?

@TheRealityofNature

I went on to create 34 more Youtube movies of Tesla CD Turbines in action. I've also created several Instructables at Instructables(dot)com/member/m­rfixits that you can check out.

Basically, I use faucet water pressure or compressed air...and then both together, to spin Tesla CD turbines as high as 15,000 rpm. I've made them run without bearings, shafts or seals.

I am developing a 2 inch Tesla turbine generator, but haven't defied thermodynamics...or gravity yet!

@MrfixitRick

ah, righto, so how efficient are the turbines? forgive me if I don't want to watch 34 movies in a short time to find out the answer to my question in a short time.

thanks.

@TheRealityofNature

The efficiency of the Tesla turbines I made from recycled CD cases and CD's was not at all my priority. The fact that it could be done at all, and besides drive a magnetically attached skilsaw blade, at high speed, on air or water pressure, is somewhat amazing, I figure ;)

However, I calculate my Tesla turbines range in the 2 to 10 percent efficiency range under load, if that is the number you are looking for.

@moqutpar

 I prefer spinning liquids instead of them spinning me!!

@DukeObjectivist

Sorry you are disappointed.

You must get that a lot in life.

For a faster moving experience, see and hear my 15,000 rpm Tesla CD Turbine revving up at YouTube/watch?v=L8v_dnIn-s0

@MrfixitRick , History channel finally came clean about Tesla and Edison. I think a movie is in order..

[gamercode100]

ahh 240p we meet again

[NOOBTUBEURASS]

most great inventors had mustaches!!!!!!!!!!!!!!

@Gerardo203

Exactly! The boundary layer effect is the principle behind the Tesla Turbine. Tesla determined it was viscosity and adhesion of fluid to the discs (emphatically not friction ;) that produced the transfer of momentum from fluid to discs.

The same boundary effect can be explained using either air, water or combustibles as the fluid source.
