Build a 15,000 rpm Tesla Turbine using hard drive platters

Build a 15,000 rpm Tesla Turbine using hard drive platters
Here's a project that uses some of those dead hard drives you've got lying around. In the Tesla Turbine, air, steam, oil, or any other fluid is injected at the edge of a series of smooth parallel disks. The fluid spirals inwards and is exhausted through ventilation ports near the center of the disks. A regular blade turbine operates by transferring kinetic energy from the moving fluid to the turbine fan blades. In the Tesla Turbine, the kinetic energy transfer to the edges of the thin platters is very small. Instead, it uses the boundary layer effect, i.e. adhesion between the moving fluid and the rigid disk. To build a turbine like this, you need some dead hard drives, some stock material (aluminum, acrylic), a milling machine with a rotary table, and a lathe with a 4 jaw chuck. Wikipedia has a good review article ( as well as articles about I run my turbine on compressed air (40 psi), and it easily reaches speeds of 10-15,000 rpm. Related:  Nicolas Tesla - A Classer

Build an Amazing Tesla CD Turbine Build a real working turbine from recycled CD's! This Tesla CD Turbine is based on the Tesla turbine, which was invented by Nikola Tesla in the early 1900's. Tesla's pumps and motors were unique in that they only used discs, and took advantage of the boundary layer effect. His smallest designs were over 100 horsepower. This Instructable is an introduction to my recently developed Tesla CD Turbine, which is made from CD's, CD spindle, pipe fittings and glue. The basic model Tesla CD Turbine shows how the boundary layer idea works to deliver power. The advanced model has many cool features, such as the use of neodymium magnets to separate the CD's with the correct gap and a Magnetic Coupler to attach implements, and much more. My next CD Turbine Instructable shows how to make a Magnetic Disc Pack and Magnetic Coupler for more advanced CD Turbine experimentation. However, please be forewarned that this turbine on air pressure is not really a kid's toy or particularly safe to operate.

S'attaquer à la turbine de Tesla! Que faisons-nous? «Puissance de Tesla! Good morning everyone! I’ve been spending the last few days doing very in-depth research on the design of an efficient tesla turbine, and I’ve come to share my results thus far! To be honest, I never knew a tesla turbine could be so complicated and advanced even though there are few moving parts and construction seems so simple. However, do not be fooled! For this turbine to have descent torque, high horsepower, and obtain efficiency up to Tesla’s claimed 95%, this turbine requires an engineer’s intellect to be properly calibrated to the most fine detail and precision. Anyway, I hope I don’t blow your mind and I provide enough sources to appease the wiki readers! Three Main Factors The most important thing to keep in mind on building a tesla turbine is the fact that we know something is important on it, but what? Inlet Nozzle Configuration The most important part about the inlet nozzle or hose is that it can deliver a high-powered jet stream directly to the gaps in the turbine.

How the Tesla Turbine Works" Most people know Nikola Tesla, the eccentric and brilliant man who arrived in New York City in 1884, as the father of alternating current, the form of electricity that supplies power to almost all homes and businesses. But Tesla was a prodigious inventor who applied his genius to a wide range of practical problems. All told, he held 272 patents in 25 countries, with 112 patents in the United States alone. You might think that, of all this work, Tesla would have held his inventions in electrical engineering -- those that described a complete system of generators, transformers, transmission lines, motor and lighting -- dearest to his heart. But in 1913, Tesla received a patent for what he described as his most important invention. Interestingly, using the word "turbine" to describe Tesla's invention seems a bit misleading. If this is true, why hasn't the Tesla turbine enjoyed more widespread use?

Wind Turbine Permanent Magnet DC Motors - Working Principle Wind energy, being one of the most important renewable energy sources, and wind turbines, which are necessary for producing wind energy, are very important in today's environmentally aware world. Below we outline detailed information about generators, with many power options right up to 7 MW, as well as one of the most important components of wind turbines and motors that is used in place of generators in individually made wind turbines. Permanent Magnet DC motors are the most important components that can be used in place of generators. The magnetic fields produced as a result of the spiral movement of the magnet within the component is that which produces electricity. Why Use a Motor to Generate Electricity? The most important reason is that it is cheaper than electric generators and it also contains many components we utilize in our daily lives. Permanent Magnet DC Motor Types for Generating Electricity Permanent magnet DC motors are divided into two groups. a.) 1.) 2.) 3.) Or; Examples

la turbine de Tesla - Partage d'idées et de connaissance Cette turbine a été conçu puis breveté par Nikola Tesla en 1913. Sa caractéristique est qu'elle n'utilise aucune pale. Comme exemple : une pale d'hélice d'avion ou d'hélicoptère. Plusieurs pales (le plus souvent au nombre de 2,3 voir 4) qui sont fixé à un moyeu central. La turbine de Tesla est connue sous les noms de turbine à couche limite, turbine à cohésion. "L'entente d'une des grandes centrales électriques de chaleur terrestre de l'avenir. ""All that is necessary to open up unlimited resources of power throughout the world is to find some economic and speedy way of sinking deep shafts." Une turbine de Tesla est conduite par un jeu de disques lisses, avec des buses appliquant un gaz sous pression sur les bords des disques. Nikola Tesla a ecrit : "'Cette turbine est un moteur efficace capable de démarrer par lui-même qui peut s'employer comme turbine à vapeur ou à fluide mixte librement, sans modification de sa construction et est très pratique de par cet aspect.

How to Pick Motors for Linear Motion | Motors/Drives content from Machine Design The easiest way to design a linear-motion system is to add components one by one. Then, step-by-step calculations relate input to power dissipated moving a load in a specific amount of time. Linear systems drive everything from inexpensive seat movers in passenger vehicles to precision laser cutters and CNC machines. The second and third steps of the approach outlined here are to choose the motor type and size. One approach for designing a linear system is to list basic requirements, add components one by one, and define every force interaction along the way. Define the problem To begin a linear design, determine the mass of what moves and how fast it goes from A to B. Load's mass = 9 kg Mass orientation: Vertical A-to-B move distance and time = 200 mm in 1.0 sec Dwell time = 0.5 sec Move profile = 1/3-1/3-1/3 trapezoid–controlled acceleration and deceleration Rotary-to-linear conversion = TFE-coated leadscrew Ø8 mm and 275-mm long Overall size: Limited to the smallest volume possible 1. 2. 3.

Tesla Turbine Wanted: these sections used to be from separate pages, i just dumped them here in the meantime. if someone can clean these up before i get back to them, that'd be awesome :) On the Tesla turbine - proceed to the simple steam engine, please. I know of one commercial tesla pump, and it is very expensive. I know of no commercial Tesla engines. We considered the Tesla turbine seriously, I had materials quotes lined up - and then I found out that a typical implementation is 40% efficient, and the best documented one is 60 at When I recognized this - and considered limited working fluid in a solar concentrator sytem - I said bye-bye turbine. I can provide a much longer discussion on the above.

solar-thermal electric generator Initial idea by Miriam EnglishAlina Friedrichsen - suggested using DS1820 for temperature measurement, and Inkscape for SVG diagrams, also pointed to some ways to program Linux to read ports. If you want to make suggestions then feel free to comment at my blog. Soon I hope to be able to add comments directly to the bottom of this page. Alternatively you can always email me via steg at miriam-english dot org to make suggestions, comments, or anything. The neat thing about this is that it gets around one of the major limitations of solar photovoltaic panels, that they only work during daylight. None of this is secret, in fact when I am finished building and testing it I'll publish all data on the net for anybody who wants to build one too. It uses the thermoelectric effect, but approaches it a slightly different way than usual. It is easiest to understand by starting at the bottom of the diagram. A solar heating panel is filled with water. Orienting the solar collector Modifications

La turbine à vapeur Tesla Nikola Tesla, célèbre dans le monde entier comme électricien, étudie actuellement un nouveau type de turbine à vapeur. Les détails précis sur le rendement et les qualités mécaniques de cette machine manquent ; mais elle a, pour le moins, le mérite de l’originalité. La turbine à vapeur est, de par son principe même, un appareil d’une grande simplicité, M. Tesla a réussi à la simplifier davantage encore, et sa solution a, en outre, le mérite de fournir une turbine rigoureusement réversible, pouvant tourner à volonté et avec le même rendement dans un sens ou dans l’autre. Voici, d’après Scientific American, les caractères essentiels de la nouvelle machine. Dans les divers types de turbines aujourd’hui en usage : de Laval, Parsons, Curtiss, Rateau, et autres, la vapeur d’eau abandonne son énergie aux ailettes motrices, par choc, par pression, ou par réaction. Le fluide pénètre par B, ajutage qui peut être divergent, droit, ou convergent. M. Signalons aussi que les études actuelles de M.
