The Tesla Turbine is not to be confused with the Tesla Magnet Motor. Both of these
inventions look similar and often get mentioned together but are not the same at
The magnet motor is a perpetual motion device which runs on magnetic energy, basically
creating a continuous supply of free energy. On the other hand, the tesla turbine
requires an external energy supply usually in the form of steam or some other fluid
supplied at pressure.
This article is going to discuss the Tesla Turbine in terms of how it works, it's
overall efficiency and the best place to get plans to build your own model.
The Tesla Turbine, also known as the bladeless motor, boundary layer turbine and
flat-disk turbine, was patented by Nikola Tesla in 1913 and is widely known to be
his most prized invention of all.
The main difference between the tesla turbine and the more common conventional turbines
is that the Tesla Turbine does not have rotor blades or anything which provides any
sort of resistance in order to turn the turbine.
Here's a quick breakdown of how it works.
Basically the design features a number of carefully packed smooth parallel disks
mounted on a shaft and arranged inside a sealed chamber. The dimensions and quantity
of the disks can differ depending on factors related to particular application.
Whenever any gas or fluid is permitted to go in the chamber and pass between your
disks, it causes the disks to turn by way of the boundary layer effect, which in
turn rotates the shaft. Since the fluid moves in natural pathways of least resistance,
free of the constraints and troublesome forces triggered by vanes or rotor blades,
it encounters gradual alterations in velocity and direction. What this means is more
energy is shipped towards the turbine.
This rotary motion may be used in a number of ways, from running pumps, blowers and
compressors to running cars and planes. Actually, Tesla stated the turbine was the
best and also the most simply designed rotary engine ever designed.
Tesla Turbine Kit Unfortunately there hasn't been any major commercial or government investment into the development of the Tesla Turbine. Many universities and government agencies have successfully built and constructed Tesla Turbine models, but there are not currently any models available for commercial sale. The two most popular and best models of the Tesla Turbine can be found at the Stanford University Tesla Boundary Layer Turbine page and the University of Washington Physics Department site. The Stanford site includes single and multi phase Tesla Turbine models with broad instructions and thumbnail pictures, which you can enlarge. The site design is one very long page and is quite basic. The UW site has steps to make your own tesla turbine from hard drive parts and includes instructions, pictures and a You Tube video.
Tesla Turbine Efficiency The turbine efficiency from the fluid or gas Tesla turbine is believed to be above 60%, reaching no more than 95 %. Tesla pointed out it would take 2-3 stages having a vacuum about the final stage to attain a greater than 90% efficiency. Since the price of creating this kind of turbine could be much greater compared to a (60%) single stage turbine, it does not make economical sense to create turbines of the efficiency in a commercial sense. Probably the most likely scenario would be that the first commercial turbines are going to be single stage models, most likely to be used in hybrid technology products..
Tesla Turbine Plans For domestic energy production the Tesla Turbine is not really the best choice. Tesla's perpetual motion magnet motor device is far easier to make and run for home made energy. But..... if you really insist on making your own Tesla Turbine there are two very good sites to help you and they are; the Tesla Engine Builders Association which provides free tesla turbine plans, drawings and photos but the site is difficult to navigate and not user friendly. The next best site is the Phoenix Turbine Builders Club which have plans for $90 plus $6 postage because it comes as a CD (Update: we don't recommend these plans because we've heard lots of negative comments about them, check out our top product reviews on this page).
