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 Nikola Tesla the boundary layer effect ( and Reynolds number ( (which determines if the fluid flow is laminar or turbulent).

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.

How I built an electricity producing wind turbine Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. I found a great piece of property. Energy By Tesla - Create Your Own Tesla Power System For over 90 years “Big Energy” has successfully convinced the US Government to smother and bury the biggest invention of our time… They tried to keep it hidden from you forever. Why? Because this one, simlpe invention can produce all the natural, clean ELECTRICITY! But now it’s time to expose the truth. It’s time to reveal the only system that can easily produce FREE electricity. And it’s finally time to help you – and millions of other Americans - reduce their utility bills… once and for all.

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. 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!

DIY non-hub builds, the why and how (part-1) Common hub motor kits have a simple construction, which keeps the price low (especially with Chinese mass-production). The low price and easy installation makes them the big seller by a wide margin. However, if you want a build which has unusually good efficiency (so a smaller battery can provide longer range), or…you want unusually good hill-climbing…a non-hub drive system just might be necessary to deliver your goals. Be aware that a non-hub system will by definition be more complex, probably more expensive, and is likely to be noisier. And…the biggest problem is that a non-hub system will be either very expensive (like the EGO, and the M-Drive), or the more affordable drives have issues with longevity and component breakage (Cyclone and GNG). We’re not knocking Cyclone and GNG, they have no way of knowing if a customer is using their kits for light duty or racing…and non-hubs are often about reaching for exceptional performance.

Tesla Coils: Unleash the Aether Nikola Tesla's most significant contribution was not AC power, radio, or the induction motor, but what we call the Tesla Coil - a tool which allows for the power of the aether to be unleashed and harnessed. Now being launched through an open source project. by Hank MillsPure Energy Systems News The inventions of Nikola Tesla are numerous.

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.

DIY Homemade Tesla Coil Check our facebook page for updates and special offers The aim of this design was to get the highest voltage (or longest arcs) possible from a single self contained unit. Check out the new 1kW Tesla Coil! WARNING: High Voltage Device! This coil operates from 12V or 24V SLA batteries. A pair of car ignition coils are used to provide around 20kV for charging the capacitor bank. Nikola Tesla On His Work With Alternating Currents VII. Theory and Technique of Energy Transmission Figure 78.Experimental demonstration in the Houston Street laboratory, before G.D. Seeley, Examiner in Chief, U.S. Patent Office, January 23, 1898, of the practicability of transmission of electrical energy in industrial amounts by the method and apparatus described in U.S.

Tesla Turbines From PESWiki Directory of Tesla Turbine technologies. Rather than using blades and friction, the Tesla Turbine uses parallel, closely spaced disks that tap viscosity. 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.
