    "But the merits of this lighting outfit do not rest on the turbine alone. The dynamo associated with the same is perhaps equally noteworthy by its simplicity of construction, high efficiency and rare and valuable properties it possesses. It consists of a smooth cylindrical body mounted on the turbine shaft and arranged to rotate within a magnetic field of novel forma. There is no brush or sliding contact whatever, the current being taken from stationary terminals to which the ends of the generating coils are connected. By employing the best materials and workmanship and resorting to artifices of design, a most economical electrical generator is produced, the efficiency being over 90% even in machines of very small size having rotors of not more than 2 1/2" in diameter. This generator possesses extraordinary qualities, especially desirable in electric lighting. It is capable of furnishing a current constant within a minute fraction of 1% through a very wide range of speed variation, and as such is ideally suited for running arc lamps or kindred electrical devices in series. More surprising still and also of greater commercial import is its capability of maintaining a constant potential. Such results as are obtainable with it are wholly impossible with other types of electrical generators. It has been found in practice that all lamps but one can be turned off suddenly without the slightest perceptible flicker and even without any observable effect on the needle of a delicate instrument indicating the voltage.

    That an apparatus of such simplicity and presenting so many salient advantages should find an extensive use in electric lighting might be naturally expected, but its overwhelming superiority will be better appreciated when it is stated that it occupies hardly more than one-tenth of the space of apparatus of the usual forms and weighs less in proportion. A machine capable of developing 1-kilowatt, for instance, goes into a space of 8 x 8 x 10" and weighs but 40 pounds. It takes not more than one-third of the steam consumed in other turbo-generators of that size.

    The guiding idea in the development of this new machine was to evolve a mechanism approximating a static transformer of energy in simplicity, efficiency and reliability of operation. Every detail has been worked out with this object in view. There is no exciter, no commutator, brush or sliding contact whatever, no centrifugal regulator, voltage controller or any such complicated and hazardous device. The machine consists of but a stationary solid frame and two smooth cylindrical steel bodies mounted on a strong shaft arranged to rotate in bearings virtually frictionless. No oiling is required, although a small quantity of lubricant is provided rather as a precaution than necessity. A perfect dynamic balance is secured in a novel manner and insures a steady and quiet running without tremor and vibration. The whole apparatus can be boxed up and depended upon to operate uninterruptedly through long periods of time. The outfit can be constructed in various sizes up to 100-kilowatt or more, and should meet more satisfactorily than any yet devised the varied requirements of electric lighting on railroads, boats, in public buildings, factories and mines, and may also be advantageously utilized in connection with existing plants for replacing belt driven dynamos and storage batteries, and relieving larger engines through the night and hours of small load."



      I watched this video and decided to buy the book to see if I could learn anything else.

      I accidentally got the 1913 book instead of the 1909 book. However, it still had the information in the video above.

      What I did find interesting is this fact.

      The combustion engine replaced the "steam engine".

      The steam engine replaced the "atmospheric engine".

      So Nikola Tesla went back to basics and made the new version of the "atmospheric engine".

      • Here are the builder in Idaho's last two videos. The machine features two discs and one 8 bladed washer in the motor and two discs and a 3 bladed washer in the vacuum pump.

        None of the discs are tapered and the gaps are not very tight in the casing.

        It is also not using a diverging nozzle. It has a straight port.

        • HEAT ENGINES (BEING THE NEW EDITION OF "STEAM") 1913 By William Ripper, D.Eng. (Sheffield), Hon. D.SC.Eng. (Bristol)

          "Where the pressure inside the turbine is less than that of the atmosphere, air tends to leak into the turbine and reduce the vacuum"

          Well in Nikola Tesla's case it has to spiral down the plug hole and create even more vacuum!

          • A tight fitting balanced rotor is critical to success!

            VACUUM IS THE KEY!

            • Hi soundiceuk. I'm still here, following along with an open mind.

              Thank you for the .stl and Solidworks files. I can't see the Solidworks files (yet), I only have AutoCad 2000i. I think there is a viewer available for Windows though.

              Ok, now I'm beginning to see how this might function by recovering the latent heat of evaporation in the turbine itself.

              Something I just read in one of the Tesla interviews, “The undeniable fact is that the machine does operate, both expansively and impulsively.”
              This strikes me as an important statement when viewed in the context of a turbine and compressor combination.


              • Yes, you are right Cadman and I came to that conclusion myself within the last few days.

                This is why the boundary layer and impact compliment each other. Discs and star washers.

                Here is the first attempt at printing the one of the sides of the casing on a £200,000 polyjet 3D printer.

                It went a bit wrong according to the 3D printing company!

                They left the file on print over the weekend for 20 hours and something happened to the print. So I get this part for free even though it may be salvageable.

                They are going to have a second go after servicing the printer tomorrow.

                Here are some pics. I think the part can still work.

                I've had some amazing prices for having 50 of these made . Around $220 US dollars for both transparent sides of the casing. Which is a steal compared to the cost of one which is around $3000.

                I can get the axles done in grade 5 titanium @ £60 UK pounds each if there are 50 orders or stainless 316 @ £50 UK pounds.

                I can do 50 x stainless 316 standard Mk2 rotors for £350 each


                I can get 50 blueprinted stainless 420 bullet proof Mk2 rotors made for £700 each. An exact 5" copy of the British 186,082 patent but without the studs. I worked out the studs are for much bigger diameter discs.

                Has anyone realised that the previous post by me was the educational proof I needed to realise that air bearings made with just an air gap around the axle and no ball bearings maybe enough to support the weight of the rotor completely after an initial turn because of the vacuum?

                With air bearings the top speed goes up dramatically and also the noise level goes down as the ball bearings are not silent.

                • I have just received these photos from the 3D printing company.

                  They have serviced their 200k machine and got it to print properly.

                  I'm really happy about that!

                  I will show the other half of the casing when it is done.


                  • Hi guys, I’ve had the axle manufactured.

                    They are adding the key way on Monday but let me have it to do some experiments over the weekend.

                    The second half of casing is also done. It will be delivered today. I’ll get some pictures posted soon.

                    Here is a teaser:

                    I could have gone much faster but the reflective strip flew off. Was also worried about the axle escaping.

                    • Grade 5 titanium axle without key ways.

                      Key ways are being cut tomorrow.

                      Axle and bearings in exhaust section of casing. Looking from above down the exhaust ports.

                      Exhaust section of casing. In my effects to eventually make the casing completely transparent, I've hand sanded this face with 600, 1000 & 2000 grit so far.

                      Yesterday I received some 3000, 5000 & 7000 grit sandpaper.

                      The next step will be plastic polish.

                      I would like to get all the faces lapped and also the rotor discs but I've run out of money.

                      I've got just enough to pay for the rotor, washers and shaft to be finished.

                      I'm aiming to for a full disclosure for 4th March which is my 39th birthday!

                      Here are some shots the 3D printer sent me of the inlet section of the casing.


                      • Hi folks, here is an update.

                        The engineering company manufacturing my axle and finishing off my rotor didn't get the 17mm reamer for the star washers on time. So the parts will be completed this week.

                        In the meantime I have been sanding and polishing my casing.

                        The hard work is paying off. The strange discovery was that the material is like a hologram. You can't see through it on the X axis but you can on the Z axis and also at various angles.

                        There is still loads of sanding and polishing to do to finish it off.

                        Here are a few photos of progress.

                        I lay claim to the simplest turbine design that uses the fewest tools for assembly / disassembly.

                        Here are a couple of possible gauge attachments to fit into the port at the top of the casing. One is vacuum and pressure and one is pure vacuum.

                        I will update my progress in the week.

                        Word from Idaho is he has rebuilt the Tesla Turbo that made its first appearance at New Years Eve. It briefly showed itself as a holy grail machine and because he glued the rotor to shaft it went into a polycarbonate meltdown because the rotor made contact with the casing.

                        We chatted on messenger this morning and he told me he put hot humid air into the turbine and snow came out of the twin pump exhausts!


                        • What a impressive looking build! Can't wait to see that baby run!!!


                          • Congrats on your progress. Really looking forward to see it run. I'm thinking this could be a real asset for drawing water from deep wells. Regular AC deep well pumps take a tremendous surge on startup, and generally add a significant cost to one's electricity bill. I'm looking at alternatives for mine.


                            • What is even more interesting is that you won’t have to pump the water from the well.

                              The machine is a condenser.

                              A mechanical capacitor.

                              Air goes in and cold imploded water and air comes out.

                              Still waiting on my rotor and axle to be finished.

                              I’ve bought a couple of other parts today just for fun. I will share them soon!


                              • Cool.This is also consistent with the findings of Viktor Schauberger regarden vortex-related phenomena in water and air.
                                Looking forward to seeing more.
                                All the best.
