    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!

    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 A NEW EDITION OF "STEAM") 1913



    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".

    NIKOLA TESLA'S HIGH SPEED TURBINE DRIVEN DYNAMO


    "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."

    "This is the greatest of my inventions," Tesla went on with great enthusiasm. "Now take my 'rotating field', do you know my rotating field, are you familiar at all with electricity? There are millions invested in it already. Well, that is a very useful thing, but the field is limited to dynamos and motors. But here you have a new power for pumps, steam engines, gasoline motors, for automobiles, for airships, for many other uses, and all so simple."

    "But is it really true that you have produced 110 horsepower from a wheel only 9 3/4 inches in diameter and two inches wide, as has been reported?" asked the interviewer incredulously.

    "Oh, yes!" was the reply. "And more. We could get more power. We had 125 pounds steam pressure and no vacuum. We ran it that way for hours."

    "Was it sustained power?"

    "Yes, sustained power. And we could only use part of the drop in pressure; we would have twisted off the shaft, it was so light, if we had been able to use all the energy of the steam. I had to put in a smaller nozzle on that account."


    I'm in the same boat with my turbine design. I've calculated that a rotor weighing 1500 grams with a 127mm diameter, spinning at 156,000rpm will have more than 500 horsepower stored in inertia.

    The axle I'm having manufactured starts off life as a 20mm grade 5 titanium bar.

    The axle parts that stick out of the bearings are only 8mm.

    I've no idea how much load this can take.

    I'm not really looking to run loads off the shaft long term.

    It would be interesting trying to build the dynamo Tesla describes on page 1 of this thread.

    I'm all ears for ideas on that, especially as my speciality is more mechanical than electrical.

    Hi folks! I'm going to write a bit about the British Patent 179,043.

    Until I understood the fountain patent it was my favourite Tesla patent.

    It is responsible for opening up my eyes to the possibilities of what the Tesla turbine can do when built correctly with a tight fitting rotor and bearings that are capable of ultra high speeds over 100,000rpm.

    Tesla must have understood that repetition is key to teaching because he repeats himself a lot in the turbine and related patents. On some subjects more than three times per patent.

    I've highlighted the parts that I think are most important in this patent.














    Here is the cleaned up version of the British Patent 179,043 "Improved Process of and Apparatus for Production of High Vacua"

    https://www.dropbox.com/s/ezqztmbah3...79043.pdf?dl=0


    There are some important things I've noticed within this patent.

    1. Tesla states adding a vacuum to a turbine will increase efficiency from 50% to 100%.

    2. He claims this is the evolution of his pump from previous British Patent 24,001. This is the same patent as US Patents 1,061,142 & 1,061,206

    3. Tesla claims that by having this vacuum pump fitted, a hole of considerable size can be drilled in the condenser.

    THE TURBINE IS THE CONDENSER!!!

    4. Tesla claims that having a low back pressure is essential to high economy.

    5. Tesla claims the vacuum pump works best inserted between the turbine and other pump. I believe he is referring to the 1,061,142 patent or fountain patent.

    I think there are many designs of rotor that will work.

    The tear shaped rotor is a definite. Tesla Mk2 rotor is another candidate.

    Not only will is pump the fluid, it will also increase the power of the vacuum. Now looking at the YouTube video of the collapsing railway tanker we all know that inches of mercury count.

    The larger the pressure difference between atmospheric the more economic the machine.

    If 1/25 horsepower does that many gallons per minute. Imagine the lift the design I present will have when it can store over 500hp worth of inertia.

    Drawing a few horsepower should be like a fly trying to stop a train!!

    "But in all such cases independent pumps of small volumetric capacity were used to raise the water to an appreciable height which involved the expenditure of considerable energy, while the spectacle offered to the eye was uninteresting. In no instance, to my knowledge, has a great mass of fluid been propelled by the use of only such power as is required to LIFT it from its normal level through a relatively short space to that from which it overflows and descends as a cascade, nor have devices especially adapted for the purpose been employed."

    There are a number of alternate designs that appear to use the discs but have no holes. There was another that appeared to draw water through a fluted turbine which in turn turned a generator to produce power.

    Edit: There does appear to be some variants that do employ the use of his pump design but are quite different from the ones shown above and there is no volute.

    Hi Charlie,

    The fountain patent mentions pump.

    Now we already know Tesla's best fluid pump with a volute is featured in his two stage machine.

    So the turbine is used as the propeller and the pump used as an amplifier.

    This is a device that features some specific magic. I think we'll all be shocked when we see the results!

    This is the stage 2 I'd like to build most. I used to fly in my dreams when I was younger but it was hardly ever like superman. It wasn't always very smooth hahaha!

    Looks like I've stumbled onto a better dream!

    The motor at the top isn't needed as the fluid leaving the turbine propels number 9.

    This then amplifies what the turbine is capable of as the casing gets cleared at a faster rate.
    Just trying to catch up here after being away:

    I've been studying this for a little while and I believe that the reason he didn't use his pump version for #9 is that he is looking for lift as opposed to lateral force as I believe he mentions in the patent.

    If he is accurate with his amounts of flow, 100 gallons (834 lbs.)/minute is capable of doing considerable work properly configured.

    Paul is right that as the the flow cycles, the impeller shown will need less and less driving force and he was probably aiming for something that would self-run.

    Here are my parts coming together for the build of the Tesla Turbine Mk2


    Bearings rated at 156,000rpm - 22mm OD, 8mm ID, 7mm wide (Skateboard size)




    Air Tap & Male to Male 1/2" BSPP Fittings






    Casing Nuts & Bolts M10 x 150mm Stainless Steel A2 + Nyloc Nuts & Washers:








    Mityvac Vacuum / Pressure Gauge - Choice of 2








    Fitting for Gauge - Wade Hex 123 (Needs Machining a little)




    Rotor (Not complete yet)




    The casing will have to be tapped with a 1/2" BSPP for the air tap and 1/4" BSPP for the gauge fitting after it is either CNC machined, 3D printed, inject moulded or die cast.


    The port can be used to start the turbine and then replaced with a gauge once operational.

    I've got the casing in production being 3D printed in transparent acrylic. This is for educational purposes only.

    A commercial version would be better suited to die casting.

    I guess the best Tesla had in his day was casting from iron or possibly an alloy.

    The rotor is at the machine shop where I am getting the shaft, washers and end plates manufactured.

    They are going to bore the centres of the discs, washers and end plates. Then true the discs and end plates to their final diameter.

    The final step before I put the whole rotor assembly into the casing to do a test run will be balancing.

    I've found a company to do this. Their machines can balance down to 0.001g

    I'm looking forward to the test run using compressed air to start the turbine.

    I want to see all the strange behaviour my research partner in Idaho has witnessed. Pops, vapour clouds, cold air coming out, water coming out, strange water droplet patterns inside the casing and ozone production with a flame.

    Also Tesla's "Self-acting machine" is the holy grail!

    Apparently he saw that too! I saw videos, but nothing with my own eyes in front of my face. It was enough to make me sell the farm though haha! The Tesla Turbo died very shortly after new year. The rotor was super glued to the shaft. The rotor made contact with the casing and there was lots of polycarbonate that melted.

    My version should be bullet proof!

    I'm currently working on a blueprinted rotor that features 420 stainless (spring steel) sharpened discs that are lapped and weigh the same. The star washers will also be lapped and weigh the same too.

    I should have my new permanent magnetic bearing prototype finished soon too. This will allow completely frictionless rotation.

    If the vacuum machine from British Patent 179,043 is added. The rotor will be in a complete vacuum so no friction whatsoever.

    That will be interesting!

    I hope that someone else can carry the torch if I get stopped in my tracks!

    My research partner in Idaho is currently rebuilding the Tesla Turbo Mk2. That will be interesting too!

    I found this picture online. I'm not sure I agree with all of it but it is interesting.

    It was called CERN.jpg


    So after Nikola Tesla had patented the Turbine/Motor, Pump/Compressor in 21 different countries, 8 of which is his only patent, Japan, Australia and India being 3 of them.

    What did he do next? His Fountain!

    Moving onto possible Stage 2 machines:





    Fig 1 & 2 appear to be a fountain. However, Fig 3 & 4 appear to be a rocket exhaust in disguise!

    Number 9 is to be replaced with a pump rotor with tear shaped holes.

    The motor at the top isn't needed as the fluid leaving the turbine propels number 9.

    This then amplifies what the turbine is capable of as the casing gets cleared at a faster rate.












    If you want to build an air ship don't forget to build Tesla's vacuum British Patent 179,043 and then add the Fountain as stage 3

    "I know the answer: This turbine uses the boundary layer effect. That is like friction that the air has with the surfaces inside- you know that part already. This type of friction has two modes: static and kinetic. Just as with a brick sliding on the floor, the coefficient of friction is much higher from stationary than when the brick is already moving. Hence, once the turbine gets to a high enough speed, the coefficient of friction increases and the motor becomes nearly 100% efficient. This is an over celebrated effect though, because the motor cannot be in this efficient zone if it is actually doing something useful. That's why bladed turbines are used in real world situations."

    +Reginald Ford Hi, can you detail your point "This is an over celebrated effect though, because the motor cannot be in this efficient zone if it is actually doing something useful." ?

    "Yes, Pedro, I'd love to go into detail. When the blades are going close (enough) to the speed of the incoming air, the RELATIVE speed of the air and the blades is low, hence, the STATIC coefficient of friction starts to take hold. This causes the blades to start going exactly the same speed as the incoming air, which is a rare 100% efficiency. If a load is on the turbine, this will not happen. So people are always running these Tesla turbines with no load, where they excel well: going fast and doing nothing useful. Loaded, though, they might not even turn at all! Hence, as I said, bladed turbines are the real world use. IF you get the tesla turbine to that 100% efficient zone, you may be able to connect a load WHILE it's spinning and gain a useful advantage, but if the load is too much, the kinetic coefficient of air friction comes in , and the turbine will become nearly useless again."


    --------------------------------------


    I don't know if it is just increasing efficiency or if the turbine is causing a suction that exceeds the pressure of the incoming air. If so, maybe in can feed itself at a high enough speed.



    That guy posting that comment doesn't think it will happen under load. I don't know.


    Maybe gear up a motor to spin the shaft of one at high speed while pumping water and see it at a certain speed the motor becomes unloaded. That might be a first basic test. Maybe some others with experience with Tesla Turbines can comment??
    What these guys didn't understand is the three spoke washer on US Patent 1,061,206 TURBINE or 8 spoke star washer British Patent 186,082 Mk2 Rotor are the blades of the turbine.

    The are cleverly situated on the fluid path to the exhaust ports.

    The pump has round washers as does the compressor US Patent 1,061,142


    The turbine has spoked washers to take full advantage of the fluid moving centripetally from the outside to the centre taking the kinetic energy from heat.

    The pump / compressor has round washer so it can take full advantage of the fluid moving from the centre to the perimeter adding centrifugal force to the fluids kinetic energy.


    The turbine/motor is an implosion machine and the pump/compressor is the opposite machine.

    Harnessing heat centripetally and centrifugally.

    Nikola Tesla
