  1. Yes, it's a generator, or more correctly, an alternator. The circuits in the flashlight change the AC to DC before charging the built-in battery. Nikola Tesla originated the AC motor and alternator, so the shakelight is kind of appropriate with the Tesla CD Turbine.

    Folks have suggested different generator setups, and I will explore some of these in future videos.

  2. It costs less than 6 cents an hour for the well pump to run the turbine = too much fun for very little!

  3. lol, that is cheap, if only my water didnt cost that much…. ahh.. the possibilities….

  4. You could run a recirculating setup with an inline electric pump. Then you could play for pennies.

    Or use the CD Turbine outlet water for some useful low-pressure application like a garden, a pool, or to simply fill up the sink.

    I happen to be near rainforest conditions, with plenty of water to go round!

  5. Innovative 🙂

    Keep up the good work!

  6. I really enjoy your videos. I love the faucet water driven turbine. I think it is very cool that you are able to get the second flashlight to shake just by its proximity to the first flashlight. *****

  7. I think Tesla would have enjoyed an AC flashlight recharging wirelessly on a Tesla Turbine.

  8. know what you should do… make one big copper coil and see if you can power your computer. good idea though put counter weights so your turbine won't shake to destruction.

    A question how much is you water bill? by the looks of it, looks high

  9. The turbine won't be able to put out enough power to run a computer without hooking up to more pressure…i.e. the mountain creek next to me. I will try wrapping the entire case with wire at some point.

    My water bill is nil, just a few cents for power for the well pump. I could see that this would be a problem for some on water bill, in which case recycling would be preferred. Run the turbine outlet to fill the sink, a barrel or the pool, or use for low-pressure garden watering.

  10. I considered that i have all the materials all i need is magnets. will it work with ordinary magnets or does it have to neodymium

  11. You need neodymium magnets or the clutch will slip, that is, the magnetic coupler won't work. I used 1/2 x 1/2 inch N42 neodymium cylinder magnets, but you could get by with smaller ones, especially if they were more powerful. Check out my building instructions at Instructables(dot)com, see link in About This Video

  12. Hey Rick.. when will 9 be up??
    Good job though!!

  13. It's coming real soon,"SinkScience#09 – Tesla CD Turbine Power Generator." using a Subaru rad fan motor as a generator. A couple more videos in the works , too!

  14. I did consider a compressed air inlet to give a pulsed boost to the water flow. I'm familiar with the venturi principle from automotive carburettors, but I don't know if the introduction of atmospheric air into the inlet would work.

    What you suggest would be an interesting experiment, and I do need to work with different size and shape nozzles now to see what is best.

  15. hey man good work
    i was thinking about Tesla and maybe use Patent number: 390721 or Patent number: 381970
    somehow?

  16. Hey that's a cool idea!
    Too bad it broke, but now you have a great neodymium magnet to do homopolar motor experiments…see my videos called "Homopolar Motor With 5-speed Shifter " and "These Hearts Are On Fire"

  17. I selected that shake flashlight out of several because it didn't work right, and thought it would be good to show the charging action.

    If you want that effect with yours, you need to bypass the little battery they have wired into the circuit-board for the light. Or find a shake-light at the dollar store that only flashes without charging.

    Most shake flashlights have a supermagnet in the on/off button in the outer case. So pass a magnet over the light circuit-board to turn your light off.

  18. Ok…1-2 GPM gets it spinning, 30-40 psi water pressure at the nozzle. This CD Turbine unit does NOT work with steam; warps the polycarbonate CD discs within 2-3 seconds. Will work with compressed air…but gets dangerous at 15,000 rpm.

    A true Tesla Turbine loves steam. Nikola Tesla built his first 8" to operate at 35,000 rpm and about 40 horsepower, later models into the thousands of horsepower!

    There are hard-drive platter Tesla turbines on the web.

  19. GREAT VIDEO. I now have 2 favorite sites.

  20. Read the "more info" >>> for some more info.
    To sum up, the Tesla CD Turbine is a disc-type turbine based on the invention of Nikola Tesla 100 years ago.

    My turbine uses CD discs spaced by magnets inside of a CD case with a nozzle glued on, and this one runs on faucet water pressure.

    The turbine, having magnets, drives a magnetic coupler which has a connecting rod attached to the magnet inside a shake-flashlight. A second light charges by its magnet moving magnetically with the first one.

  21. Hehe, I tried that and it didn't work too well. The all north-up magnets in the turbine don't produce enough power from the coil to light the LED. It might work better with alternating n-s-n-s magnets, or with multiple coils in series.

    I kinda like the vibration and con-rod linkages…like an old Briggs & Stratton or steam engine!

  22. Tell you what…you make and sell them and I only ask for 5 percent of the gross for my share. Deal?

  23. Thanks for comments.

    The impeller is quite wide, and was an experiment to look at the vortex effects and the flywheel effects of a larger mass of fluid.

    It spins up to 1200 rpm, at about 2-2.5 gallons per minute. What you see here is indeed about 300 rpm, but with a load.

    I have found it difficult to reach above 1200 rpm on 50 psi water pressure. Do you have a CD turbine working design that does so?

  24. Do you use a central opening and the Tesla design? Or are you talking about an impeller which is an entirely different design?

  25. Sorry, I meant, do you use a central exhaust outlet like the Tesla design?

  26. Hehe, What you are talking about is an entirely different type of turbine.

    From WiKipedia:
    "The Tesla turbine is a bladeless centrifugal flow turbine expander patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. "

    The Tesla Turbine uses a different principle involving viscosity and adhesion, and smooth discs, instead of cups or blades, to transfer the power.

  27. ahah…really got you thinking, eh? thanks for the refreshing attention to detail!
    I optimized the radius of the rod on the magnetic coupler such that the magnet was moved through the coil far enough to light the LED. If the rod is any closer to the center it won't have enough back-and-forth motion to flash the light.

    Believe me, I spent a few hours with this rig to get it to do this!

  28. Tesla's design works on the principle of adhesion.

    The fluid goes into a nozzle, where it is accelerated. (Same as your designs, I presume.) As the high-speed fluid leaves the nozzle and enters the case, it is forced between a series of smooth, closely spaced discs. The fluid spirals into the center outlet, while releasing it's energy to the discs.

    A Tesla Turbine or pump will not cavitate, and the design can handle shock waves and implosion better than any other turbine or pump type.

  29. The magnets have several functions, attachments are one of them.

    There are 1/32 inch spacer magnets between the CD discs in the turbine to space them at the correct distance apart.

    There also are 6 larger 1/2 inch magnets on the top disc inside the turbine. This enables a magnetic coupling to the magnetic coupler (also with 6 magnets) that you see on top of the turbine.

    The magnets also create a rotating magnetic field that can generate electrical power with coils.

    And more…much more!

  30. Good question!

    The arm is close for best torque, to push and pull the shake-light magnet through the magnetic resistance of it's coil of wire. Also, any longer of a radius will make the rod hit on the shake-light case.

    Also, the turbine has limited torque, so it was a fine balance to get the radius to the con rod arm just right, especially to enable adding the second light.

  31. Good guess, and I certainly tried it that way, but that didn't work.

    What happens is that the neo magnet in the second flashlight gets pushed and pulled by the direct magnetic coupling action of the magnet in the first flashlight. No electro, just magnetic!

    The electromagnetic coil in the second light charges it's battery from it's own magnet movement.

  32. The shake lights are designed with very thin wire, just enough to run 1 LED. Running too many LED's could overamp the wiring. The voltage may need to be increased as well.

    But it might work for one or two extra LED's..try it!

  33. You are one cool Dud ! ! !

    Love your videos

    5 stars

  34. 私は将来を参照してください !!

  35. looks like a fuck machine

  36. jeez, you use 100 Watts to light a 0.1 Watt LED. Nice work!

  37. Very astute! Most folks just waste that power every time they turn the faucet on…what did you do with it today??

  38. beauty is in the eye of the beholder…

  39. One could set up things like you say, and the only way it will work is because of the flywheel effect to bring the linkage past that "dead spot". The momentum of the discs and magnets inside the turbine would keep the linkage moving.

    Same effect as a car engine, which wouldn't work without momentum to bring the crankshaft around.

  40. Respect for those who are capable of "DIY". I Know people who don't know how to change a light bulb. Regards!

  41. That's right, it would work, but perhaps need different circuitry.

  42. You are mad! MAD I SAY!

    I am so jealous!

  43. This movie is now available as Closed Caption.

  44. invent a dildo for girls that can do that

  45. It depends on the particular circumstances, and who is doing the measuring of what.

    For example, a regular turbine won't run on straight biomass combustion gasses without clogging up. It needs expensive filters and polishers to prepare the gasses for burning. A Tesla Turbine has recently been proven to work well in that situation, making it more efficient in that sense.

    See the wikipedia entry for "tesla Turbine" for more info on efficiency.

  46. Don't be jealous…you, too, can be insane!

    Insanity beats jealousy every time.

  47. it would be interesting to use two turbines, and reorient the output of the first to the input of the second. As well as reorienting the light output to be forward. Would be an interesting experiment.

  48. so basically youve just made a pint sized hoover dam…neat?

  49. minus the magnetic coupler of course.

  50. With enough pressure and volume, the Tesla Turbine design can power anything. Tesla had designs for cars and ships up to 10,000 horsepower. His smallest commercial turbine could be held in one hand and developed 110 horsepower. They were mostly run on steam, but are capable of running on any fuel.

  51. I like your green generator. The bottles are a cool idea. I wondered about what was used to attach the tubes to them?

  52. i wonder how much is your water bill every month

  53. My water is on a well…costs me 5 cents an hour for a whole lot of fun!

  54. How does the load of a second flashlight affect its performance?

  55. Good question! The second flashlight slows down the CD turbine a couple of hundred rpm.

    A third flashlight can be added if the water pressure is having a good day 😉

  56. I figured so, with the weight of the magnets inside the flashlight. If you're open to new ideas, maybe solder a USB slot to the battery inside the flashlight and charge an iPod? If the voltage is sufficient of course. I think a turbine iPod charger would be pretty fresh.

  57. Make a circuit with some capacitors to smooth the current.

  58. You misunderstand… the point was not to make it quiet and efficient. It's to make a cool mechanical way to charge 2 flashlights at once. For the fun of it.

    I am building a dedicated turbine-generator similar to what you speak of, but that is a whole different project, as the N-S magnets cannot then be used as drive magnets like I have done here.

  59. Yes, very similar to a steam engine setup on a train.

  60. The magnets do more than just hold shit together. Yes, they do help hold the disc pack together, but the crazy glue works better.

    The magnets act as a drive system for many attachments.

    The magnets make possible to eliminate the shaft and bearings and seals of the turbine, which is a very big idea.
    A shaft-less, bearing-less, seal-less turbine could have many applications.

    The magnets can also give power directly by using coils of wire to pick up the energy.

  61. The first thing I did with the first turbine I built was mount a skilsaw blade on it magnetically and run it at very high rpm.

    I admit it did have low torque and would only carve a pumpkin or cut 1 x 2 pine. But hey, its a CD case and CD's !!

    If I had money I'd build a powerful Tesla Turbine for a vehicle.
    But I don't, so I do funky home experiments of ideas that might inspire others.

  62. Thanks for the reply. I do apologize to a point. And yes I was having a bad day/night. And I watched that one already. And that ain't my truck and thank you for letting me know that is was still on my page so I could delete it. As for your stuff in general it ain't that impressive but neither is mine. But don't waste stuff when your doing it. Use a pump. And I'm some what sorry about all the language.

  63. Wait I got more. Why don't you put some type of fins such as old Cd's cut into slices in between the Cd's in the turbine so that you can get better rotation from the same amount of pressure. Maybe even drill holes in the center for the water to run out of where the fins meet the center, I think you would gain a bit more force there to. Also might relieve some of that pressure that is bloating out the spindle case. But I wouldn't listen to me.

  64. I appreciate that some folks have concerns about the faucet water used. I live in a rain forest where a lack of water is not so much of a concern.

    My latest movies show a recirculating system with 12 volt bilge pump run by battery and solar panel, and compressed air through a 12 volt compressor, battery and solar.

  65. Thanks for the suggestions.

    The Tesla design uses only flat discs with spacers, and relies on the boundary layer adhesion (drag) on the discs, in a smooth gradual manner by the fluid, rather than by diverting the flow abruptly. Fins change the nature of the turbine into a normal cupped or bladed design.

    The Tesla design must maintain pressure in the case to work properly. The fluid exits out the centre after doing its work on the discs.

  66. That is hard to estimate. It would depend on many factors. It would likely cost between $2000 to $20,000 to build a 10-20 horsepower Tesla Turbine. With mass production these costs might only be 1/10 of that estimate.

  67. Hi, MrfixitRick if you have any technical drawings, can make you calculation of real cost for one and ten turbines. Or enibody who is interest.

  68. What kind of turbine are you interested in? A CD Turbine like this one, made from a CD case and CD's and magnets? Or do you mean a true Tesla Turbine that will run on steam? How big do you want?

    I don't currently have technical drawings. They are available at places like Phoenix Navigation and in Tesla Turbine books.

    The cost for a 23 disc CD Turbine like in my movie is about $80. The cost for a small Tesla Turbine with metal discs would be from about $200 to $2000, depending on materials.

  69. I mean real one, i work like designer in compani who manufacture fans, we have all kind of machines. And 2000 USD is weri weri hight, I will tomorow create at work one tesla turbine from metal and will show it here, will put there drawings and price.

  70. Looking forward to it!

  71. So have add wery short video respond, about turbine what will in short time build

  72. Cool! Thanks for the video. I wish you success in your turbine building, and let me know how it goes.

  73. Can you allow me video respond, that can ewerybody see what we are talking about.

  74. Thanks for the reminder; it's been approved.

  75. The water can go where it is needed…to fill a sink, water a garden or any other low-pressure supply. I have a well that costs 5 cents an hour to run to provide the water, and live in a rain forest with no lack of the wet stuff!

  76. Thats nice.. whats fun when you think about it is that you can use the same mechanism but to power another product… 😛 that can be usefull if the power goes out, you can charge your flaslight, then maybe power something else? ike a radio? or would it need more power?

  77. @skullzcrusher

    It can make a watt or so of power from faucet water pressure, so it could power a small radio. The usefulness in power outages works as long as the water pressure continues.

  78. Love it bud, great use of free power…id have gave you 6 stars but it only went up to 5 😛 Now if the power goes out ill be getting free power from my tap and the phone lines 😛

  79. LOL I was thinking, that it's kinda cool, but kind of defeats it's self because your expending power to power it. But then the second one added! Still kinda useless, but a very cool theory.

  80. Those shaker flashlights are SO useless!

  81. And yours was useful?

  82. lol Just buy a flash light that plugs into the wall, that flash light is suppose to avoid using power from a utility company, ether way I like it and I get where your coming from. You solved the true problem with it, that you have to shake the damn thing for it to work. Dude Im just a lazy. However you could have just used your time and energy to shake the damn thing rather than inventing whatever that contraption is you got going there

  83. Funny machine, but exactly what is the practical use?

  84. I would love to know how grossly inefficient this system is: how little energy that shake light is putting out for how much energy that water pump is using?

  85. @HeBreaksLate

    If the water pump is running anyway, say to fill a sink, then this system is 100% efficient. If the pumped water is not used, then this system is about 1% efficient.
    BTW, efficiency was not one of my criteria in this experiment.

  86. @MrfixitRick I figured efficiency wasn't a prime concern. It never was for Tesla. A lot of amazing proof of concept stuff, but very little that we practically use today.

  87. @HeBreaksLate

    Tesla invented the radio…is that not practical?

    Most AC electric motors today are of Tesla design, such as found in the amazing new Tesla car.

    AC electric wires on poles over long distances have also proven to be fairly practical; Tesla pushed hard to make that happen.

    And I understand that the original Tesla Turbine at Niagara falls is still working…

  88. @LUCKY4908
    I get water pumped from a well. It's rained for about 8 months, so there is no lack of water here.

  89. I was wondering if you know this? if the magnet was an electro magnet connected to a battery then moved in and out like your doing here …would there be more electricity generated?

  90. @bkfilipi

    There could be more additional electricity generated if the magnet was an electromagnet…but it would require additional force to make it run.

    Unfortunately, this device was at the limit of power that the faucet water pressure could produce, so an increased magnetic field with an electromagnet would stall the motion of the device.

  91. wont the capacitor blow up from over charging?

  92. @lookkool3

    Yes, anything could happen. This is an experimental apparatus and should not be left running unattended.

  93. hey jw. if u can mod the shake flashligh to a stronger LED?

  94. Did you tried a pendulum to do the magnet movement in this flashlight? I would love to see the efficiency of such device for charging batteries.

  95. A very heavy pendulum might be a good way to charge batteries. I suggest you try making your ideas, because it is important to learn about magnets…and you might come up with something nobody else has thought of!

  96. i'll rev it up and see if it still holds together, 😉

  97. do you have any idea how much power you're producing?  

  98. Thank you. I've had an old one for a long time and it still works good.
