There are two systems that come to mind. One would be a high-speed Tesla Turbine burning gases produced from a plasma furnace type system. The high temperature, velocity and shear effects break down and combust any residual particulate matter inside the turbine, leaving quite a clean exhaust.
A better way is a thorium reactor that has no radioactive byproducts. They are being developed and are a viable no pollution, safe energy source. It could produce heat to drive a Tesla Turbine.
Whats the point if it has to be connected to an air supply? I could use an outlet? if this used some sort of interesting powersource that didnt need to be made by another machine.
Using air pressure is a fun way to demonstrate the basics of the Tesla Turbine, a 100-year-old design that Nikola Tesla said was "the greatest of all my inventions". Tesla had over 600 patents.
The Tesla Turbine can be run on any fuel (gas, diesel, propane, alcohol, natural gas, biofuels, sour gas, etc.) or pressure source (compressed air, steam, water pressure), and is the only type of engine to be able to do so. It has even run on direct combustion of oats!
The torque of a Tesla Turbine is dependant on the nozzle velocity and volume of fluid, and the diameter and spacing of the discs.
Most Tesla turbines have relatively low torque, but they make up for it in high RPM. Therefore, the total horsepower could be very high for the size and weight of the Tesla turbine.
Tesla claimed he got between 5 and 10 horsepower per pound of engine weight!
could you make some instructions for this?? i tried to copy the design but mine didnt work like yours :/ maybe its because i blew into it with a straw and not an air compressor xD
Yes, you need an air compressor for this project. And a polycarbonate cover like mine (or equivalent) for protection.
No instructions for this baby. You see, if you were to try this and it accidentally revved up too high, the magnets and CD disc shards could fly out and maim or kill you.
There are no bearings so the turbine must rev up to 1000 rpm or more to float on the "air bearing" between the CD's and the case. That's why it won't work by blowing into it with a straw.
The point of this pencil-sharpener video is to present my invention of the simplest turbine in the world. Perhaps you didn't see that in your haste to simplify.
The only problem is Mr. FixitRic babbles on & on. There is a certain group of people who will watch this video and we do not need to be spoken to as grammer students. GET TO THE POINT! Test your product prior to filming so everything works as you intend. You show a lot of good stuff but need to cut down on the jibber-jabber.
How strong are those magnets? are they more or less powerful than the rare earth magnets of the same size? I imagine that a lot of the rpm loss is directly related to the loss of pull on the magnets( not couting the pencil pressure ). love the vid..keep talkin lol. love applications like this..makes my brain work. Thanks
I use the strongest N-52 neodymium rare-earth super-magnets.
The magnetic coupler does not use any extra power. The magnets do act as a flywheel to allow better pencil-grinding under load, but the weight tends to limit the rpm's.
Ok, somebody 'splain why this is a big deal. If you use the same pressurized air line and a little turbine bladed disk on a shaft you can spin the pencil sharpener too. And not have the super-magnets pull your karmic aura force out of wack ;)
And why not just use your arm to rotate the pencil sharpener manually and burn off some of that lunch?
I like the magnetic coupling but the amount of torque would have to be less then that of one connected to a runner or shaft like in the patent designs. This isnt to say it's a bad design but i would be using this design in areas that require minimal torque, like building a generator by this method near a source of water etc... It CAN sharpen a pencil but i believe it would require less energy to sharpen the pencil if it was done using shaft mounted discs. This is a great design and keep going
me and a friend are trying build a Tesla cd turbine, but unfortunately it seems that the orbit watermaster extension nozzle has been discontinued. I know you say that many objects would work for a nozzle, but I was wondering if there was a specific nozzle that you would recommend?
(irish accent) i dont think she can hold up to th' stress capt'n
lol you should add a weight to increase inertia, of course it will be slower to start up but when it gets to speed it will stay there, i would make one but i dont have the extra cd's or the time to do it.
“I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success... Such emotions make a man forget food, sleep, friends, love, everything.” Nicola Tesla
I imagine we will soon see these devices advertised on Tee Vee for the usual $19.95! (But wait! Order now and we'll send you TWO turbine pencil sharpeners, just pay additional shipping and handling)...
Seriously, a great video, I really enjoyed it.
I assume the magnets are simply for coupling and the discs are the Tesla turbine?
Tesla was a genius. Where would we be today without his AC power?
You are correct that the magnets are used for coupling. This is my attempt at a bearing-less, shaft-less, seal-less, improvement on the Tesla turbine design.
Haha is that polycarbonate stuff expensive? Also is it chemically resistant? I'm building a fume hood at the moment, that stuff looks perfect for the window. Then again im not gonna be detonating any C4 in there so it might be overkill.
Polycarbonate (Lexan) is expensive, but so are new eyes.
If there is any chance of flying debris, use polycarbonate. For example, acrylic is not bulletproof like polycarbonate, and it will shatter when stressed.
These magnets are the neodymium supermagnet kind, 1/2 x 1/2 inch size. they are available online for about $2.50 each from K&J Magnetics. The link is in the expanded description box.
I never mentioned getting more energy out of the system. The energy comes from the sun (solar panel) which charges a battery which runs an air pump into a storage tank. No grid power.
One point is that I have invented a tesla turbine that is the simplest means of making rotational force from air pressure. It has no shaft, no bearings except air and no bothersome shaft seals.
The other point is at the end of the pencil, and it was a heck of a lot of fun getting to that point.
The Tesla turbine has many practical applications, and it can run on fuel and is much more efficient than an auto engine. A Tesla turbine with a magnetic coupling could have lots of applications when made of proper materials.
This is great! I've done you one better though... I've taken my Tesla turbine powered pencil sharpener and made it more environmentally friendly. It took a little machinist work, but I removed the air connection and replaced it with a hand crank. Totally human powered!!! Needs no other power than a bowl of Wheaties in the morning. I need to do some more time tests but I think I have developed a circular cranking technique that will compare (speed-wise) to the original compressed air fitting!!
Great video ! just one question... when you say you can run it from a air storage tank ultimatly fed by a solar grid, how long does it run with a fully charged battery ? and how long does it take to fully recharge in optimal conditions ?
The fully charged battery will run the air pump for the storage tank for probably about a half-hour to an hour. It takes about 15 minutes for the little compressor to fill the tank to 120 psi. The full air tank will only sharpen a pencil or two before getting too low in air.
My solar panel is small, and would take several days to fully recharge the 12 volt deep-cycle car battery. A larger solar panel and bigger battery would be a better combo for real-world use.
I completely agree with the statement at the end. Funny that I can't go 2 hours at work without food, but when I work on my creations I can literally go without food or sleep for 2 days at a time. Kinda unhealthy, but hey, nothing would ever get done if we all threw in the towel at 5pm. What part of CA do you live in, you look familiar? Great entertainment! Keep it up!
The Tesla CD Turbine goes way beyond being a pencil sharpener. The pencil sharpener magnetic attachment simply demonstrates the potential of a magnetic Tesla disc turbine design.
The Tesla CD Turbine is a model based on the same principles as the original Tesla disc turbine, which the prolific inventor considered his "greatest invention". I added the magnets to it.
Tesla said his disc turbine would "scrap all of the heat engines of the world", and it is my intent to continue that plan.
Thank you very much for a thorough explanation. It is very interesting--seems like a good way to reduce wasted energy from heat radiation. I'm a bit rusty on my physics but I think I get it.
THE most awesome and most dangerous pencil sharpener i have ever seen! i don't expect to find this in the average classroom anytime soon:) incredible job by the way.
Ok, what am I missing? I see an air hose hooked to a couple of CD's. The air makes the CD's turn. Which in turn is hooked up to a pencil sharpener. What are the magnets for? I don't see him disconnecting the air supply? Are the magnets doing anything? I know I must be missing something??? I don't get it??
The CD's are not hooked up to the pencil sharpener. There is a 1/8h inch air gap between them. The 4 magnets of the turbine form a magnetic coupling with the 4 magnets in the flywheel of the pencil sharpener. This enables the torque of the turbine to be transferred to the pencil sharpener.
Records could work ok with a water-pressure based system, but I consider them too dangerous for high-rpm use on compressed air, because they could fracture. CD's are at least designed for more than 33 rpm!!
Could be fun to determine the upper rpm limits of LP records, though...
Because as humans we still need to learn to live with each other and take responsibility for ourselves before we are allowed to have unlimited energy.
That is one of the best utube comments I have ever read. Are those the same as rare earth magnets? I use them when building RC planes and I can get them dirt cheap...if they are the same. Also how does increasing the # of discs increase torque output. I understand the turbine itself would have more inertia but how would this affect transmitted torque without a physical connection? What is the efficiency between the turbine and the flywheel? Sorry aboot (hehe) the questions! PM me. Thanks
Each disc has a certain amount of torque that it generates due to the forces of adhesion and friction pulling on it from the fluid movement. The forces are additive: if one disc can produce 1 ft-lb of torque, 10 discs will be 10 ft-lb, etc. (As long as the fluid volume is increased)
The rotating inertia of a flywheel is a separate issue from torque.
yeah buti kno its a awesome design but kno one get fiqure out any torque thats the only thing it would do 10,000 but as soon as u load it up the revs drop straight away u could hook it up to a gear box through a centfrifgual clutchs but .....
I was going to hook it up to a fishing reel to get a 3:1 reduction in speed, and a 3 x increase in torque. If there were more discs in the turbine, the torque would increase.
I plan on simply adding another turbine to the existing one to double the torque and increase rpms too. They will stack and couple magnetically. I hope to make them modular, so it's easy to add 2-disc turbines to increase the power when required.
Imagine 100 CD jewel boxes all stacked up to make a 2 foot long motor...
Tesla offered his Tesla Turbine to several auto manufacturers including Ford, but was turned down. The internal combustion auto engine and all its inefficiencies became the norm. Even before Tesla's turbine, major development money had already been put into bladed and cupped turbines with secured patents.
However, now there is a chance that, with modern nanotube/ceramic materials, the Tesla Turbine may still do what Tesla wanted, "to scrap all of the heat engines of the world."
I mean your carbonite... unbreakable box. not the turbine. Tesla was too much before his time... people found something to make money and didnt care about health... we failed.
Oh, I get it... sorry for the confusion. Cars are not made of polycarbonate because it is very expensive compared to cheap-and-subsidized steel. Some cars are made of strong plastic, like the Saturn doors.
i was worried that this was going to be another one of those crazy free energy devices, glad to see you arent claiming that. cool device, Tesla was way ahead of his time.
I only claim "free" energy when I run this turbine by way of a air storage tank, pumped up by a 12 volt compressor, that is fed from a battery with a solar panel charging it. Then it's free energy in the sense that it doesn't cost for grid power.
tesla was scary to think someone could invent such things. If he said that was his greatest invention it makes me wonder why we dont use this tesla turbine......
The original Tesla Turbine had some problems with disc warpage due to heat and stretching due to rpm. It is my belief that both of these problems can be surmounted with the use of modern materials such as carbon nanotube ceramics.
Since the price of these exotic materials is becoming more reasonable, the use of the Tesla Turbine may soon become a reality. A quiet and reliable Tesla turbine-alternator would be the perfect addition to extend the range of electric cars, for example.
I have to say AC electricity was his greatest invention! If it was up to Edison we would have DC power plant's like we have TELCOS for phones today!
Tesla kind of got silly towards the end with the wireless idea and that's why he lost investors... A great mind...could you imagine what he would create with today's technology?
Tesla was the greatest inventor ever, he also invented fluorescent lights, cordless electricity (thats right no power lines needed), and an electric car powered by energy from who knows where (the cosmos?), among others. His great inventions would have taken power away from his financiers, thats why they are not in use today.
There is only one turbine in this movie. It is the CD jewelbox. I am demonstrating a revolutionary magnetic Tesla Turbine, not a bladed or cupped turbine or a waterwheel.
Awesome invention, I want one in my trig class, my pencil always breaks from so many notes! I like your taste in music too. Nice to see that people of all ages like Wolf Parade
Looks to me there would be a significant lack of torque, unless you had an incredibly heavy flywheel, which may make it more difficult to drive. But, as drafter200 said, there's a lot of energy loss in this. Drive it with something other than air and perhaps it would be greatly efficient.
The Tesla design was made to run at high rpms.That means from 15,000 rpm to 30,000 rpm would be the sweet zone of torque and efficiency for this size turbine.
Unfortunately, my $5 turbine will blow up long before that!
If you want more torque out of a Tesla Turbine, increase the disc size or the nozzle pressure, or gear it down.
The point is not to improve the electric pencil sharpener, but to show something different in concept.
This is just a first step to incorporating magnetic fields and shaft-less magnetic drive into a real Tesla Turbine. The turbine can then act as a generator or as a magnetic drive, or both at once.
The Tesla Turbine can run efficiently on any fuel. With modern nanocarbon ceramic materials, it could power your home or car, with less emissions than an internal combustion engine or a furnace.
please excuse my ignorance but ive seen a good bit of interest from different users on the topic but i fail see whats so great about the tesla turbine. i understand the elegance in the simplicity and high speed rotation always sounds cool but i dont see many advantages over other air engines. I admit ive done next to no research into the topic, that being said please school me on the advantages of the tesla turbine.
As seen here, this Tesla CD Turbine is basically an air engine and not very efficient. The original Tesla Turbine was designed to be used with steam and combustible fuels and can be quite efficient.
With the correct materials, a Tesla turbine can run on any fuel with little or no pollution. The Tesla disc design was recently proven to be the only type of turbine that can run directly on 100% biomass combustion products.
The "simplicity and high speed rotation" you mentioned translates to cheaper, lighter, and more power for its size.
Tesla was getting 5 to 10 horsepower per pound of engine weight, and we should be able to get at least double that now. Compare to a V-8 at 1 to 2 horsepower per pound.
The Tesla turbine is small and simple, yet powerful and quiet. Fitted with an alternator, it could be the perfect auxiliary power supply for an electric car...or power a house.
u have to consider dat da tesla turbine is good in some applications but it doesnt have any torque n u not need rpm as much as u need torque in a pencil sharpener.
You could shoot air onto the disc, but it will not develop enough power to grind a pencil. The CD jewelcase directs the air in a circular spiral into the centre. As the air passes through the CD discs, it takes a long path of several feet to disperse its energy. That can't happen in the inch or so of airstream exposure to the flywheel disc on the sharpener.
I wish my teacher called me Mr.Student lol

I need to do some more time tests but I think I have developed a circular cranking technique that will compare (speed-wise) to the original compressed air fitting!!

MrfixitRick 2 years ago
Great video ! just one question... when you say you can run it from a air storage tank ultimatly fed by a solar grid, how long does it run with a fully charged battery ? and how long does it take to fully recharge in optimal conditions ?
Keep up the good work !
chuz00 2 years ago
@chuz00
The fully charged battery will run the air pump for the storage tank for probably about a half-hour to an hour. It takes about 15 minutes for the little compressor to fill the tank to 120 psi. The full air tank will only sharpen a pencil or two before getting too low in air.
My solar panel is small, and would take several days to fully recharge the 12 volt deep-cycle car battery. A larger solar panel and bigger battery would be a better combo for real-world use.

seems like a lot of work just to sharpen a pencil...what's the point of a Tesla CD Turbine...shoot--what exactly IS a Tesla CD Turbine?
joejumps4fun 2 years ago
The Tesla CD Turbine goes way beyond being a pencil sharpener. The pencil sharpener magnetic attachment simply demonstrates the potential of a magnetic Tesla disc turbine design.
The Tesla CD Turbine is a model based on the same principles as the original Tesla disc turbine, which the prolific inventor considered his "greatest invention". I added the magnets to it.
Tesla said his disc turbine would "scrap all of the heat engines of the world", and it is my intent to continue that plan.

Thank you very much for a thorough explanation. It is very interesting--seems like a good way to reduce wasted energy from heat radiation. I'm a bit rusty on my physics but I think I get it.

toiletman666 2 years ago
Ok, what am I missing? I see an air hose hooked to a couple of CD's. The air makes the CD's turn. Which in turn is hooked up to a pencil sharpener. What are the magnets for? I don't see him disconnecting the air supply? Are the magnets doing anything? I know I must be missing something??? I don't get it??
mageedis 2 years ago
The CD's are not hooked up to the pencil sharpener. There is a 1/8h inch air gap between them. The 4 magnets of the turbine form a magnetic coupling with the 4 magnets in the flywheel of the pencil sharpener. This enables the torque of the turbine to be transferred to the pencil sharpener.

Records could work ok with a water-pressure based system, but I consider them too dangerous for high-rpm use on compressed air, because they could fracture. CD's are at least designed for more than 33 rpm!!
Could be fun to determine the upper rpm limits of LP records, though...

hominidae7sp 2 years ago
That is one of the best utube comments I have ever read. Are those the same as rare earth magnets? I use them when building RC planes and I can get them dirt cheap...if they are the same. Also how does increasing the # of discs increase torque output. I understand the turbine itself would have more inertia but how would this affect transmitted torque without a physical connection? What is the efficiency between the turbine and the flywheel? Sorry aboot (hehe) the questions! PM me. Thanks
B4its2L8guy 2 years ago
Thanks for questions:
I live on Vancouver Island by Sooke.
Yes, they are rare-earth neodymium magnets.
Each disc has a certain amount of torque that it generates due to the forces of adhesion and friction pulling on it from the fluid movement. The forces are additive: if one disc can produce 1 ft-lb of torque, 10 discs will be 10 ft-lb, etc. (As long as the fluid volume is increased)
The rotating inertia of a flywheel is a separate issue from torque.
Turbine to flywheel = 100% efficient
MrfixitRick 2 years ago
yeah buti kno its a awesome design but kno one get fiqure out any torque thats the only thing it would do 10,000 but as soon as u load it up the revs drop straight away u could hook it up to a gear box through a centfrifgual clutchs but .....
Tunerboii2045 2 years ago
I was going to hook it up to a fishing reel to get a 3:1 reduction in speed, and a 3 x increase in torque. If there were more discs in the turbine, the torque would increase.
I plan on simply adding another turbine to the existing one to double the torque and increase rpms too. They will stack and couple magnetically. I hope to make them modular, so it's easy to add 2-disc turbines to increase the power when required.
Imagine 100 CD jewel boxes all stacked up to make a 2 foot long motor...

RythmTR 2 years ago
Tesla offered his Tesla Turbine to several auto manufacturers including Ford, but was turned down. The internal combustion auto engine and all its inefficiencies became the norm. Even before Tesla's turbine, major development money had already been put into bladed and cupped turbines with secured patents.
However, now there is a chance that, with modern nanotube/ceramic materials, the Tesla Turbine may still do what Tesla wanted, "to scrap all of the heat engines of the world."

Fermions83 2 years ago
I only claim "free" energy when I run this turbine by way of a air storage tank, pumped up by a 12 volt compressor, that is fed from a battery with a solar panel charging it. Then it's free energy in the sense that it doesn't cost for grid power.
MrfixitRick 2 years ago
tesla was scary to think someone could invent such things. If he said that was his greatest invention it makes me wonder why we dont use this tesla turbine......
TheElectricUndead 2 years ago
The original Tesla Turbine had some problems with disc warpage due to heat and stretching due to rpm. It is my belief that both of these problems can be surmounted with the use of modern materials such as carbon nanotube ceramics.
Since the price of these exotic materials is becoming more reasonable, the use of the Tesla Turbine may soon become a reality. A quiet and reliable Tesla turbine-alternator would be the perfect addition to extend the range of electric cars, for example.

Tesla was the greatest inventor ever, he also invented fluorescent lights, cordless electricity (thats right no power lines needed), and an electric car powered by energy from who knows where (the cosmos?), among others. His great inventions would have taken power away from his financiers, thats why they are not in use today.

Tesla also invented AC electricity, and the radio. The first automobile speedometer, ignition coil, and sparkplug are among his hundreds of patents.

Looks to me there would be a significant lack of torque, unless you had an incredibly heavy flywheel, which may make it more difficult to drive. But, as drafter200 said, there's a lot of energy loss in this. Drive it with something other than air and perhaps it would be greatly efficient.
mrhinman 2 years ago
The Tesla design was made to run at high rpms.That means from 15,000 rpm to 30,000 rpm would be the sweet zone of torque and efficiency for this size turbine.
Unfortunately, my $5 turbine will blow up long before that!
If you want more torque out of a Tesla Turbine, increase the disc size or the nozzle pressure, or gear it down.
MrfixitRick 2 years ago
this is nothing more than a Rubegoldberg device your using magnets to transfer energy from an air compressor
eliminate all this and just use the electric motor from the air pump. you'll elliminate a lot of wasted energy.
drafter200 2 years ago
The point is not to improve the electric pencil sharpener, but to show something different in concept.
This is just a first step to incorporating magnetic fields and shaft-less magnetic drive into a real Tesla Turbine. The turbine can then act as a generator or as a magnetic drive, or both at once.
The Tesla Turbine can run efficiently on any fuel. With modern nanocarbon ceramic materials, it could power your home or car, with less emissions than an internal combustion engine or a furnace.

please excuse my ignorance but ive seen a good bit of interest from different users on the topic but i fail see whats so great about the tesla turbine. i understand the elegance in the simplicity and high speed rotation always sounds cool but i dont see many advantages over other air engines. I admit ive done next to no research into the topic, that being said please school me on the advantages of the tesla turbine.
rdzombie 2 years ago
As seen here, this Tesla CD Turbine is basically an air engine and not very efficient. The original Tesla Turbine was designed to be used with steam and combustible fuels and can be quite efficient.
With the correct materials, a Tesla turbine can run on any fuel with little or no pollution. The Tesla disc design was recently proven to be the only type of turbine that can run directly on 100% biomass combustion products.
MrfixitRick 2 years ago
The "simplicity and high speed rotation" you mentioned translates to cheaper, lighter, and more power for its size.
Tesla was getting 5 to 10 horsepower per pound of engine weight, and we should be able to get at least double that now. Compare to a V-8 at 1 to 2 horsepower per pound.
The Tesla turbine is small and simple, yet powerful and quiet. Fitted with an alternator, it could be the perfect auxiliary power supply for an electric car...or power a house.

u have to consider dat da tesla turbine is good in some applications but it doesnt have any torque n u not need rpm as much as u need torque in a pencil sharpener.
jithin15 2 years ago
It's correct that the Tesla turbine tends to have low torque, especially at low speeds. Adding more discs to the turbine would increase the torque.
I had the option of making a gear reduction out of a fishing reel, or try a flywheel and more rpm. I chose the flywheel because I had the parts.
Although it doesn't actually increase the turbine torque, the flywheel stores some of the energy and makes the sharpener work smoother.
MrfixitRick 2 years ago
why use the magnets at all? ycouldnt you shoot the compressed air directly onto the disc connected to the sharpener?
madoo15c 2 years ago
You could shoot air onto the disc, but it will not develop enough power to grind a pencil. The CD jewelcase directs the air in a circular spiral into the centre. As the air passes through the CD discs, it takes a long path of several feet to disperse its energy. That can't happen in the inch or so of airstream exposure to the flywheel disc on the sharpener.
