when i worked for lockheed i saw them working on magnetic bearing system without magnets they were using light and high density plasma to generate the magnetic field had to wear anti static suits wired to a ground around it the plasma formed into lines of force looking like a toridial pattern looking allot like a rodin coil
interesting - never heard of it - thanks mate
Sounds like you were working at area 51
Wouldn't a generator spinning whit magnetic bearings be superior to current friction bearings ?
This is great. I love it. You comment to view ratio is super high so you are getting a lot of people who are interested and curious about what you are doing.
is it? I didn't know that and to be honest that is super cool - it is a fascinating world!
I absolutely love how you utilize the precise machining of manufactured objects in DIY projects. You need to drill a hole in the center of the magnet? Well this thing has a magnet in it with the center already marked in the factory :) cheers man.
Right, DIY'ing using stuff others made is pretty fun. Who needs to make their own magnets when you can have them factory made and shipped to your home for super cheap lol.
@@Rick-the-Swift unless u dig the ground with your bare hands for the materials, u're using somethibg that others made. it's about finding a good threshold
@@timucinbahsi445 Agreed, I admit I was being a bit facetious, as I perhaps mistakenly thought you were in your original post as well. But yes, I like to upcycle, whatever whenever I can. For instance, why throw out a toilet when it makes a perfectly good garden planter?
Totally agree- don't underestimate the value of well engineered and manufactured ingredients when mixing your own concoction.👍
Thank you for reaching this. I’m thinking this concept should be used with a bedini circuit
That was a great idea Rob I got so many ring magnets from magnetrons but now I am going to start collecting them off speaker cos that center drilled out is the bomb !
it just makes it so say mate
@@ThinkingandTinkering easy it does !So I suppose you could convert a remote control car to maglev suspension then ? 😂😂 would be great!
Glad to see you doing this. I just use 1/2" PVC with some microwave magnets. Depends on the center diameter of the magnets. Stacking block magnets in circles will increase the strength of a single ring magnet. FYI use a metal base to face the magnets all the same direction. The north pole lifts more on the northern hemisphere. The south pole lifts more in the southern hemisphere.
nice info mate - cheers
I am definitely going to make one of these Robert thanks you for your brilliant ideas and inspiration to me that's the easiest and most effective maglev iv ever seen thanks mate 😊👍💯❤
I can see you making good use of this mate - it would make a very good generator for sure - cheers
That's great! Thanks again mate 👏
I am glad you liked it mate and I am sure you will find a use for it
@@ThinkingandTinkering for sure! 😎🙌
awesome lol
Beautiful mate. Its like real life magic
magnets are the closest things to magic in this world.
Now slap some magnets on top of the flywheel snd aluminium pan above it to see if we can brew some coffee by induction :). great vid as always
Thanks again TNT fascinating video, it just up my thinking as a garage scientist, and I'm sure quite a few of the others watching new things to be discovered..🤔👍🤔
Glad you enjoyed it
it could be a nice water engine too . thx for all the fantastic info
Great stuff Rob 🎉
Would be fun to watch a quick part 2 video with a stack of round magnets as the shaft or different long cylinder magnets as the shaft to see how their fields interact with ring magnets
That’s really interesting Rob. Look forward to the next vid 👍
cheers mate
It is very interesting video Tom Stanton made on the subject. I’m glad to see you giving it a go. As it would translate to a turbine nicely. a combination of the three type of levitation would work even better. Magnetic induction being the driving force. It would be cool seeing a load of these scaled up and stacked up. Glad I’m not the only one thinking this is a good idea. Kudos to you rob. There might be a brake through in energy physics yet!
I think you said a lot of what a lot of us on here agree on many things be discovered yet just up my garage scientist thinking..🤔
Isn't this concept unviable unless on gas bearings in a vacuum or something sophisticated like that? I guess this might be good for low power applications like in survival for running a light. I've often thought about this design but couldn't come up with the practical applications for it or how the energy ROI works out.
cheers mate
Great project! Will the radial forces on the bearing be excessive?
Would make a great wind driven generator 👍
it would indeed
Cool! Just thinking, a heavy flywheel like that on an efficient magnet bearing ~ would smooth out gusts of wind on a Vawt turbine. The flywheel would keep spinning when there wasnt any, until the wind picked up again. Would support a whole lot of weight too :) Anyway, have a great day, suns out
If you remember those plunger toys. Where you just repeatedly pressed the plunger and it would cause a disk to spin well. That sound exactly like what the wind would do here. Like it! Great thinking!
@@jasonhaymanonthedrawingboard oh yeah, i remember those. A spinning top, with a plunger, and it used to humm lol
@@jasonhaymanonthedrawingboard Hi, ive sent you an email. Some ideas
@@DiyEcoProjects nice! I’ve already replied with a few suggestions.
always a good day when the sun is out mate
Great idea, could be modified easily into a Hatem ou cogging device.
interesting cheers
Good stuff!
Does magnets loses magnetism while in sudo levitation ?
Very cool idea. 👍👍
Thank you! Cheers!
I have been wanting to make a flywheel gen from old drum brakes w compressed air/vacuum forces to spin it
I have been thinking for a long time that using a magnetic bearing you can make a super efficient fan or even an air turbine, with a very small input Watt.
The flywheel can be used as a propeller with magnets in a circle)
4:00 Spin it in the same direction as water going down a plug hole
ok
Free energy when people who go gym make energy and not waste it
yep!
Could you machine out a vee cone in the two magnets as a pair of bearings to support the shaft ??? That would be totally self supporting and make for totally frictionless bearings. Then put it in a vacuum somehow and the flywheel should spin for may be a week or more. Just an idea.
Interesting... a horizontal wind turbine? I'm thinking!? Thanks!!😁😁
The flywheel can run in a vacuum and vertical? Close to zero resistance?
SO i am assuming "absolute ages" is one minute . I like your videos .
pretty much - time is such a relative thing as are the forces applied lol - I am glad you like the videos mate - cheers
Nice!
Another 3 magnetic and you have a fully balance flywheel that can be in any position. Yet go with the Earth axis ;)
Gerard Morin has the right idea but had no magnetic bearing and over 4 years ago i said i would make one. I did way better?
Legend
Oh neat! You fixed the cogging issues with a baring. Now how do we keep a spin on it? With more magnets? Magnetic cogging is much more difficult to solve to make the magnet wheel spin forever. It requires good magnetic shielding and that was difficult for me. To overcome the magnetic cogging bump is the hard part.
Not sure yet
Why isn't it possible to use a central magnet of lower power surrounded by stronger magnets around it to create a magnetic valley in which a magnet could sit within (create 3 arrangements like this), then have 3 magnets stuck to a triangular platform (to prevent it flipping over) sitting in the 3 magnetic valleys? then you would have a totally isolated magnetic damping platform?
Question is can this be done in a stable manner, with the right amount of mass on the platform, you would think this might work.
Combine that with an upright wind turbine and let the wind continue charging your flywheel...
Now in a vacuum and a vertical mag bearing
awesome! 😆
lol - cheers mate
If I invented a geometric shape of 2 round magnets that can levitate above each other and lock in each other's magnetic field, would you be interested?
How many RPMs can you get
I am developing a friction-free, fully free-floating, maglev axle design. It utilizes the natural curvature of the magnetic boundary in the X and Y axis of possible motion to refute any push off and hence, true magnetic stabilization. I may release the plans in the future. I may not.
maybe but it is well worth working onion you do mate
@@ThinkingandTinkering if i can get it working, I will be sending you the plans to build it. Its simple in theory, but requires a bit of precision balancing and bloody strong magnets for the X and Y axis. A key factor to note is that the stronger the gauss rating of a magnet on it's surface, the less it's magnetic volume will be, but, the greater its flux density. Knowing this, you can use extremely strong N52 magnets as directional stabilizers for multiple axis.
Is it not doing work or having energy taken drained from it by the magnetic field?
no mate - it's doing work because I spun it
@@ThinkingandTinkering but being a magnet in motion is it not creating a current in it's vicinity whether or not there is something conductive there to resist. If that doesn't slow it down you could remove all air resistance by doing it in a vacuum and then seek a solid material that is magnetic but not metallic or conductive and you have a levitating and spinning object that will spin forever
@@SodiumInteresting look into M.E.S.S. technology. Mass Energy Storage Systems.
I guess this is a perennial question, but how do permanent magnets do work, eg holding up a weight against gravity, without dissipating energy?
I don't mean to be facetious here mate - I am being serious - but I suppose in the same way a table does after all that holds up weight against the force of gravity. I believe surfaces don't actually touch they just look like they do there is a very short range force called the Casimir force that keeps them apart. If all the drains in a material are aligned like in a magnet we can see that separation - I think that is pretty much what is going on here
@@ThinkingandTinkering Point taken. I think the issue is whether work is being done, if so, laws of thermodynamics should apply....or if not, we just accept it's as you say, a mysterious quality of nature like gravity, that we just accept as a given.....
@@mfr58
I tend to ignore these so called "Laws" as laws they are not. Just workable opinions to help attempts to decribed what is observed. They are assumptions, not Laws, base on a fixed set of circumstances like gravity, air pressure vs a vacuum.
The so-called law of conservation of energy is a perfect example, as it is a theoretical construct never intended to be applied to the physical universe yet is applied by people to the physical universe erroneously all the time. When I question these people of letters phds and such I remind them that the law of conservation of energy is a theoretical construct and was never intended to be applied to the physical environment. The usual have nothing to say but insist it's a law, even when I get them to admit it doesn't apply to the physical universe.
Einstein's theory of everything failed because what applies in large cannot be applied to what is in the small it breaks down.
In college Tesla's professor called his alternating motor concept a Ponzi scheme.
If you plan to think outside the box you may want to look at all assumptions of reality as possibly only applying to a fixed set of predetermined things like gravity, air pressure, vacuum. Take these fixed forces out of the equation or counter them and all of a sudden laws don't apply.
All who made advancement in any Field of endeavors challenged what was already accepted.
OHM'S so called Law was heavy rejected and he lost his job over it. Was in practically hidings for some 30 years.
Same for Tesla they prosecuted him mercilessly.
connect it to a wind turbine and hey presto!
go for it
A Tesla turbine perhaps?
It's a little stressing for me when you overlap videos where you are talking. It's so interesting what you're saying that it feels like someone keeps interrupting you.
Random personal confession 😂
I understand mate - but I am trying this method out to see how it goes - keeping it fresh mate lol
Interesting, I quite liked when it became a voice-over because you could see what he had been doing as he was talking about it.
wrong. you still have alot of friction when using actual bearing to keep it on a vertical axis
you do indeed - but this pseudo levitation not levitation - just to say wrong is a bit insulting you know - you might want to rephrase that a bit - just a hint lol
Why does everyone I've seen try this use flat on flat magnets?
that's what they have and what is easy to get hold of cheaply?
Availability and some ignorance combination.
@@ThinkingandTinkering availability for some yes, folk that repurpose what they have (repurpose is good, done so all my life) but there are folk that would drop $$ on projects too I've followed the magnetic bearing set-ups used for a while and I just don't see anyone trying to work with geometry other than flat on flat which I really find odd. When I have thought about this, what comes to my mind is: with bar magnets, and the speaker magnets (well ring magnets really), you could arrange the bar's in a V shape and the speaker as shown. Using say two off the shelf plastic oil funnels as shape forms, glue attache the bar magnets to the outside of one and inside of the other. Like to like of course, that should remove a lot of the X and Y wander, then use the pair of speaker magnets as shown here to retain the cone in cone so there is Z-axis stability as well.
practically impractical, otherwise speaker manufacturer would be making bearings
Out of context but I got a great idea I would like to share with you all:
We can combine the soda train principle with serpolet instant steam production system!
Soda train like others steam engines were gave up because they were storing the steam and therefore had an explosion risk due to excess pressure inside the tank. But this issue was fixed by the serpolet steam engine, made by the Frenches Serpolet brothers. On top of the fire run a pressure resistant pipe inside where the water move in a very thin patt by capilarity. Water enter one side exit at steam at the other side. Therefore no risk of explosion.
So a bit of soda and water can produce steam for a while, then be replace by a "fresh" dry soda, adding some water to it to keep going on. Since soda exothermic reaction produce 300*, there is 200* available to use for drying or at least starting to dry the used wet soda. Now since i beg that the steam from this process may content some soda, it can be reuse in a closed system to wet again some soda.
Even part of the water used for the turbine may be recollected by condensation (adding an urea endothermic reaction that produce cool could be an extra option).
An other possibility is just to use soda generator on this principal to charge battery for electrical car, plane and so forth.
never heard of serrpolet before now mate - brilliant heads up many thanks for sharing the idea
What if you put a third magnet on the other side of the flywheel magnet, and flipped it horizontally, secure them on the far ends.
it would fall out - with horizontal arrangements the weight is a bit of an issue
@@ThinkingandTinkering a well fit bearing on the shaft wouldn’t fix that?
I’m thinking the repelling magnetic forces would secure the middle magnet if the two on the end are secured, then reduce resistance but that’s not using your 2lb flywheel
yes but what then would be the point as it would be the bearing carrying the load not the magnetic field
give it a go mate = let me know how it works out
