Looking forward to this. Your really good at explaining things, how they work, and how to do it.

I come for the Turbines, but stay for the spin art. Cool vid Dan, great ideas!

Dan, that's a neat demonstration.

Thanks. I needed a support bearing for spraying abrasive ceramic material on a spinning work piece so not a great environment for a conventional bearing - abrasive dust makes it a non-starter. I had thought of air bearings and magnetic but after playing with some small magnets I was troubled with the sideways tendency ( anyone who has pushed same poles together will hopefully know what I mean ) I had convinced myself that I would get lots of additional friction on the spindle because of this. I can see from your demonstration that is not the case and your weights are in the range I need to deal with. Gut feelings are not always reliable - sometimes you gotta suck it. Great - sharing something helped someone else on their way - thanks for sharing.

awesome demo of levitation. . very interesting!!

Great work. Thanks for posting.

Wow, that was great!

@MrSterlingHarris You're a legend. One of my favourite Brockway calls!

Exactly what I was thinking! Would be an interesting concept!

You should have a look and see what is happening to the magnetic fields on those magnets!

Thank you for the nice comment.

This would make a great support for a turntable plinth. Provided the eddy currents didn't affect my tone arm and related components. Thanks for sharing this with us!

Exactly what I needed ❤️ Thanks mate

Spin Art...cool!

@MrMaleBee Thanks!!! Garage Band and the free loops they have, there is a ton you can do with that program. I actually do most stuff on a Mac Mini with Garage Band and Imovie 6 (Newer imovies stink)

Great video

Neat idea. I've been playing with Neo magnets for a long time and see how useful they would be in this application. I have also built a tangent bearing by drilling a hole partially thru a thick alum plate of a dia slightly larger than my shaft. Then drop a steel ball bearing into the hole for the shaft to ride on. Thus, the only contact point is the top tangent of the ball meeting the shaft. My first turbine would spin like crazy with practically no friction. The only prob was replacing the ball occasionally because it would rust in the weather.

Nice Flywheel ! Regards, Stefan.

You are freaking awesome! I honestly think hoverboards are on their way!

Wow a great video. I will watch your other videos too. Nice spin art, didn't know about it until now. Will try it some day it seems cool.

Brilliant!

Yes I was trying to make a handmade magnetic carosel for my nephew for Xmas but failed B4 seeing your superb video. I see my mistakes now & am inspired to try again. MERCI ! Mark Summerland BC Canada

Thanks for sharing, good instructional!

Top Spin + this

Cool stuff!!

I have a teflon addition and a stainless rod for the newer version.

hi dan. your videos are great, been watching for ages. i hope you're well and start to make more again when the weather gets better. just rediscovered this, but can't find anything on the suggestion made by another commenter regarding two vawts spinning in opposite directions. did you ever try it?

The poles are to isolate in this central rotation. I am working on a DIY generator/alternator but there is a ton of loss with current DIY setups. Trying to figure ways of maximizing the current. For now, standard Permanent magnet motors are tough to top. Dan

:-) Thank you for the nice comment.

where do you purchase those magnets from?

i need some of those magnets now!!

That type of magnetic thrust bearing idea has been used on watt hour meters so theres no mechanical thrust washer to wear out letting the disc drop, and drag and make the readings slow

Hi Dan, I like the neodymium levitation idea. Could you post a link as to where (and which ones) you got the magnets I'd love to get a set for my project VAWT. Thanks and cool art!!

that's cool you could totally make you own clay/sculpture spinning thingy!

Thank you. This is very helpful, I'm trying to build a vertical PMG to get free electricity

@4eightyvolt :-) THANKS

My first turbine worked great - (see previous note below) - but I had trouble building the generator because I didn't have machine tools to get the close tolerances req'd. But since one can buy a generator, I decided to focus on building a very good turbine and just buy the gen to couple to it. I would use the "Freedom II PMG" from Missouri Wind and Solar. I suggest you watch Jeff's video on it - on You Tube. Skewed coils so NO cogging for a couple hundred $$'s.

nice! Makes me wanna do this too! I still didn't get the turbine thingy yet though..

wow those magnets are pretty sweet. I need to get a set of those and a rod. I could have a lot of fun with this.

Dan, I got some Neodymium ring magnets to create a magnet bearing for a kinetic sculpture. The problem appears to be that the rod itself seems to have some pull to the magnets which does not allow the rod to turn freely in the magnet. Does the rod have to be a non-magnetic material? The rod you are using appears to be a steel rod. How is that not causing a problem?

Where did you get magnets with holes through them? Thanks for a great video.

I am enjoying your videos, and i am learning new things about wind turbines and how to make one. I am very interested in making a wind turbine , i didnt know anything about the neodymium magnets and it seems like a good idea. hope to see more of your ideas

Great explanation, Thx... ;) It will help my friend understand my project I want him to help me build... ;)

Nice, as usual, I wish you could do 5 videos a week, that would be great. 5 star.

bloody interesting, sir, thx for posting

Nice job

Looks like you're having way too much fun there Dan ;)

what strength and size neodymium magnets did you use? If I was to build a wind turbine what would you reccommend me to buy in neodymium? size, strength form?

Nice idea

Just wondering, where did you get those magnets that you are using as the suspension and shock absorbers? What are the dimensions of them? Thank you for sharing and your cool designs.

im going to make a concept drawing for a piece of art with this :) im not really into physics but the effects of these cool things are really interesting.

you re the coolest mn this s incredible thnks so much for sharing the vid

do they have magnet springs for cars?? pretty cool to think about it

You are the einstein of engineering man!

well, thats great. Can u guys show it in a video(if possible) so we all can see a bit clearly how it works on larger scale ?

Excellent

AWESOME!

Hi, the two magnets, being metal also produce eddie currents in each other - so it will damp any up and down movement

question is the repelforce of a magnet the same as the pullforce

Nice. What's the second half about?

Does the magnetic force fade over time..?

how did you get the hole into the magnets? did you just clamp it well and put her on a drill press?

wow oh wow. awstrucked. really superrrrrr

awesome!

cool vid!

It would be neat to use the same magnets for both the levitation and generator, a dual use, it would be good also.

When he was pushing the magnets together, I was waiting for his hand to slip and the magnet to fly up and hit him in the face...

Impressive

oh ... and also i didnt understand the thing with the bearing in the center of the magnet ? And larger system? what do u mean how much larger?

execelent.............. nice structure...

They do not get hot, and also a bearing on a larger system would be recommended in the center of the magnet. The magnets basically act as the load bearing and damping system. If the magnets were to ever fail, the unit would just come to a slow stop.

very nice video !!! this is real art

Hi, This rod was steel but a stainless steel rod will have less resistance. You will still get some resistance from Lenz's law with any metallic rod but not an issue at RPM below 1000. The weight and diameter of my turntable makes the resistance a non-issue. Smaller diameter flywheels and lighter weight tables would need stainless or carbon fiber/ fiberglass fishing rod.

do they use these for suspension for cars and stuff..and how long does they repel

I love your videos and always wait for you to come out with new cool ideas. What i was thinking about this levitating turbine was that. Would it be possible to have them with least possible friction and then use a DC motor with a battery to rotate them, while having a magnet and coil configuration much denser to produce more power then what is consumed to rotate the turbines ??

do they make car suspensions with magnets? or just springs and ir ones?

Great video Dan! I cant wait to see the finished turbine, especialy the part were you will show us how to stabilise the horizontal axis. I am trying to build a VAWT magneticly levitated but I do not know how to stop the top part from wabeling all over the place :P Once again thanx for the video and kep up the good work Dan. Apreeciate all your vids ;)

How long will the magnets support that weight before loosing their magnetic energy ?

at the end looks fun ;D

it's really cool.......and sound gud

You could make a good sit and spin outta those

Interesting the uses arre endless. Magnetic energy... will be a big part of the future for sure.

How long will it spin with those weights on(30pounds), if you give it a good spin?

Hey Dan if you would put a strip magnet around the wheel or the table under the wheel and use magnet reversed just like the center to balance and have almost no friction or cut grooves in the wood near the center and make them opposite of a center and again no friction. I have a million Ideas but no one to help. I have a bad back and enjoy you guys sharing your ideas we should have free energy by now.

ok thers one question im interested in : u said that theres less friction... i want to know if theres some little amount of it does the magnets heat up ? .... and if they are what temperature can they reach ???? i rly need to know that pls respond asp .. ps great clips

been a while since video. magnets look good need to be balanced as shaft bending repeatedly. I am looking at 20' diameter 30' high. center shaft be supported top and bottom.

ide still see if i can slip in a bearing or 2 somewhere for the horizontal wear.

@mancamiatipoola i am unclear on how your generator would function. How does it generate power exactly? Are you suggesting a permanent magnet motor in space?

Does this mean the resistance force of the magnets is less than the pull force of one of the magnets? Thought it would be the other way around...

is it possible to set up these magnets in a way so that they opose eachother to create some sort of magnetic field like a generator?

would it wobble less if the magnets were larger radius? and fit tighter to the axis? trippy ending...cool stuff

how long these magnets can levitate?

Have you thought about getting magnets with a larger center hole and inserting low friction ceramic bearings into them?

wow, hey where can i buy those magnets i'm very interested

Hi, Folks like me, really appreciate your videos...I personally learn from them, BIG THANKS! Q: What size NEODYMIUM MAGNET are you using (to hld 35lbs of weight separate)? And what do they go for these days?

I was thinking this would do absorber for vehicle. would the total weight differ after the load levitated?

@Ultranothing Thank you ;)

Newbie. I find this very informative

How much load could that hold if you had used the more expensive N52 magnets?

where did you get your magnets?
