The Making of the Prototype Tesla CD Turbine





Introduction: The Making of the Prototype Tesla CD Turbine

This video shows the initial thought process and first attempt to assemble a working prototype Tesla CD Turbine.

The thought process starts with... if McGyver met Tesla, and they wanted to do something cool to recycle CD's, and save the planet besides, what would happen?

A neodymium magnet ring comes into the picture, and a prototype Tesla CD Turbine is constructed.

You can order the BEST neodymium super-magnets from K&J Magnetics here.

    Well, if the idea behind omitting the written explanations was to remove we not anglo-speakers, has turned out of wonders. I can read the English acceptably, but I don't understand anything when I listen it. Especially if the pronunciation is not very clear.

    I admire this work and i feel you can be of great help to me. Im working on a tesla turbine project and i had a few questions which could aid me if answered. Could you work backwards to create a prototype? Like starting from the power? What do you recommend as a choice of power rate for a small scale tesla turbine prototype like yours?

    The power range for a small Tesla turbine is quite varied, depending on the rpm potential, the pressure and volume of fluids going into it, and the number of discs. Generally, a 5 or 6 inch size Tesla turbine might range from 1 watt (like mine on faucet water pressure), up to 50 kilowatts like Tesla's first small turbines that ran on steam.

    More pressure = more performance = more money required for exotic materials and processes

    There is a saying in racing, "Speed fast do you want to go?"

    The power rating of a Tesla Turbine will be directly related to the nozzle inlet pressure, specifically the speed and mass of the particles. The power increases with the square of the speed of the discs, and directly with the number of discs. (Double the speed, 4X the power. Double the discs, 2X the power.)

    The turbine nozzle will be designed to be small enough to give a maximum speed to the incoming particles, but large enough (or use many nozzles) to pass enough volume of material.

    Starting from the power, you need to decide what type of power. The Tesla Turbine can run on all these materials and more: steam, compressed air, gasoline, propane, water, helium, straw and hay, etc.

    Will the turbine run on compressed fluids, or by burning a combustable?


    But, you felt compelled to produce this practically unintelligible video instructuble! So much for progress.

    I made this video before my 3 instructables. It shows the initial thought process for inventing and prototyping. Guess I'm an idiot for thinking it would be appreciated. I guess intelligence isn't your specialty, either.( "instructuble" is spelled "instructable".)

    Your work IS appreciated, mrfixits.

    I propose you "the second mile": to write the speaks of the video as text. I like your work.

    Hmmm, good constructive idea, rimar2000. Thanks, I'll think about that!

    Thanks, I have seen them already, and they seemed me very interesting. My observation about the video was more by the purpose to bother than because I fell it thus. I am a little joker, but not always that is done evident. Besides, I understand that this page is in English language and I have to accommodate me it, in the measure of my possibilities.

    hey man, i reelly like this thing, im gonna attempt to make a hydrogenerator using the radiator fan engine, but i dont quite get how u made the inlet pipe.
    i understand that water flows throught the cs box making them turn but what does all that complexity about the pipe connecting the tap to the box have to do with anything?
    if it's crucial i hope u can elaborate for me on what to do about it :)
    also, does it matter if the magnets inside the cd box are like triple the size of the ones u used? cuz i cudnt find ones that small...
    thanks man ur awesome :D
