An unusual arrangement in that it uses magnetic bearings - for the bearings you will need 1 12mm ball bearing,2 x 15mm by 3mm neodymium magnets, 1 x 10mm by 5mm magnet nd 8 x 10mm x 2mm magnets
That combined with your previous pen nib bearings and in a drainpipe would make an awesome hydrogenerator
yes it would!
@@ThinkingandTinkering hi Robert thankyou for the informative videos. Do you know if AA size salt batteries exist
@@ThinkingandTinkeringif the fan was mounted in a tube just bigger than the blades and you collect the wind from a bigger cone at input to basically compress the airflow but also guide it down the tube to minimize the wobble on blade could that work?
@@pietpompiepompiepiet940 dude I love the way you think. I would love to see a practical application for this. Maybe collapsible cone, I would love to see one approximately 12" or 30cm model. If it could recharge a phone or tablet this would be marketable.
@@mingwangchung hi thanks for the reply. If I had a 3d file of the cone impeller then I would print it to the scale of the tube just to proof the theory.
Hello, from Kalamazoo Michigan Robert . Archimedes turbine, 1 ball bearing as pivot, magnets, some opposing. Wind powered generator, using only human breath. I can see lots of school science projects coming from this and many other projects that Robert has done.
This is a good idea! Smaller turbines require less wind to rotate than large turbines. This could be scaled up with several small turbines in a fence and then have a screen around it to prevent birds from flying into it.Also it could be built into architecture such as bridges and property fencing to reduce optical blight. Awesome idea!
It's doing the same work as a 3 cent solar panel.
I'm not sure a screen would be ideal. I think you'd be robbing your efficiency
Wind is a fickle thing...
It is disturbed by the smallest things in ways that are detrimental to the ability to use the air movement to harvest power.
Normal recommendation is the bottom of the wind turbine be 30 feet above the highest obstruction within a very large radius.
Your screen, even "chicken wire" would naturally interfere with the wind and greatly diminish the ability to harvest power.
Interesting concept. Look forward to a scaled up practical implementation.
Interesting concept. Look forward to a scaled up practical implementation.. your enthusiasm & energy are contagious, keep up the great work.
I agree....
This is a very interesting design Robert. I see great potential for this design to provide ultra efficiency output for the owner
The Texas Engineer has the US Patent on the Tornado Turbine many years back. . It is regarded as the best windmill design for generating electricity. Photos of it are included in wall posters of various designs of windmills. Looks like a farm silo at a distance with small upper 360 degree automatic directional vanes catching the breeze and the air swirls down inside the spiral large vanes to the main large electrical generator that is above your head. The fast air exits out the sides at an upper level.
the archemedies turbine due to its shape is also self cocking and works in winds of just a few kmph. it will always point into wind just because of its shape so its always receiving maximum possible wind load on maximum amount of surface
The exact video I needed as a follow-up to the last. Great work as always Robert!
Glad it was helpful!
Your video is very interesting; you remind me of the first steps of Mr. Gernot Zippe (Mr. Steenbeck's son-in-law),
when he was looking for the right compromise to build his first centrifuge.
For the record, he used the magnet (1948/1952), and the needle at the bottom was made of piano wire steel,
to make a beautiful little needle, (like the needle of the phonograms of the time)
the needle turned at the beginning in a small concave oiled container!
Finally, it is also the fact of creating a vacuum in this process which allowed great reliability of the rotations...
Marvellous !! I love the joy you show about your working project. Makes me laugh in sad times. Thank you.
Ball point bearings!!!! Always a joy to watch
Do you think it reasonable to use a pointy insert on the end that floats into a matching cone-shaped dent in the frame, and then fine-adjust the distances so that the point would enter the dent just enough that it stopped the excessive wandering around of the floating end?
I will say, it's always fun to see your face light up like a schoolboy at the little joys...like huffing and puffing away on a new toy. 🫶
YEEEEEESS!!!! I've always pondered exactly this when I saw those holders!! Thank you for sharing Rob!!! Cheers!
Finally a power generator driven by hot air - we should strap one to every politician’s mush
Might be more efficient to capture the methane from their BS
Would love to see a 3d printed fluidyne engine! Using household copper for the receiver and running on solar energy. A Great channel for the young engineers like me!
Great suggestion! i like the fluidyne
one design adjustment ... then ends should to be swap-able the Metal Bearing end will probably wobble less with the generator magnets attached then the free float magnets end
you have way to much fun
Amazing! I was recently thinking how a Di Vinci Aerial screw between magnets, thank you for being awesomely innovative, and ingenious.
Love it! Was a lil concerned about you passing out though, Rob.😂
lolol - me too
That little giggle at the end😂
Fascinating, as always! If I get the assembly, the ballpoint bearing is on the windward side of the turbine, so the wind thrust would pull the bearing away from the bearing surface. Would turning the turbine around allow the bearing to carry the wind thrust? That might stabilize the wobbling a bit and support the thrust.
Dear Robert,
Here in Chearsly , Bucks, we have a three phase supply lines to an
empty disused and unconnected old pig unit.
A hillside location, where two telegraph poles hold
the transformer above the removed old metre
Inside the building are lots and lots of electric fans, some quite big
Millling ones, grain bins etc. others ventilators
So from what I have learnt from your lessons; I hope is:
It would be mad not too collect all the biggest motors
Four biggest for first morning
Get them on the Hill by the power box
Support them facing upwards (as high as possible)
Use farm made barrel turbines. Out of plastic 50 gallon barrels
Or whatever’s best under trial
Get a bod and electrician too collect the whole lot together and open a new power company account metre below
transformer for them
to connect too and start feeding power
back down lines
Robert , assuming that the sparkys know there stuff ;right this and that wires etc
and the fans turned with the prevailing wind
I can’t see what’s not to like
Am I mad or not
Using barrels would protect motors from rain up on two gate posts
Love what you do
Sincere one
Henry
P.S I’ve worked on the farm for twenty seven years, but my channel videos make it look like I am a rock star
I am not. Only for fun.
Possibly also create a magnetic or electromagnetic stabilizer, so it's completely frictionless.
Robert Murray-Smith the Happy Inventor Genius
Just found your channel.
pure platinum, my friend.
If you ever want to visit Alfred University, I'm sure I could get that ball rolling.
The issue with magnets for bearings is: The rotor wanders a little. When trying to generate electric power, this can cause The rotor to contact the stator since you want the gap as tight as possible for maximum efficiency. Also when the electrical load changes the gap will change again. Fun for demonstration purposes but not practical in real life.
The wobbling can be resolved by aerogel rings laden with water 💦. Water has its own ability to move electricity ⚡️ and aerogel is insularité as it is cushy. The pressure will release counter pressure from water as it wobbles.
Safe for space
@@diversitylove5460 not practical for wind turbines. Normal bearings work just fine.
cool. I bet that turbine would make a really good boat propeller.
Nice video! I'm so going to 3d print this to play with!
What a beautiful design. I'd love to make a wind turbine like that in my backyard on a large scale and see how my neighbors react =)
make sure you put it on a easy swivel pedestal as archemedies turbine self cocks due to shape so it will always point into wind if you give it a swivel base. theres a german company that makes them about 1m across that turn out 1.5kwh in anything 4kmph or higher wind wise
i was lobying a decade ago to get them installed on all floors of office blocks above third story because due to wind currents they make they always have 4kmph+ winds & it would have turned office blocks into power plants rather than massive power sinks but nothing came of it, they dont do it the way they do it because its cheaper in short term they do it way they do it because they hope to steal most of the resources when it all collapses
Omg you are my idol! I never knew someone could do this as a job… Now I have a goal !
That is really cool! I wonder if you can put enough magnets to make it so strong it could have a pulley and belt, or a sprocket and chain added to it?
Could you constrain the wobble with magnets around the axle?
Water tubine. In an expanding tube. Magnets on edge of wheel. Coils outside tube walls. And as another commenter said, put the bearing on the other end.
I'm retired now and I worked with Rotary Screw NH3 (Ammonia) refrigeration compressors for the most of my working life. I was aware that there was research and some progress with magnetic bearings both for the large electric drive motors and the compressors. Something like that would reduce starting amps and in essence be frictionless for stationary rotating equipment. Have you ever heard of this path of research?
Scaled up equals more bearing magnets and even less friction. Love the turbine too.
cheers mate
It's not a turbine but just a windfang. A turbine is used to work against a force to produce energy. How do you want to transfer this energy without pushing your mechanism out of the magnetic field?
Man i love this idea.keep up the good work!
You can literally use a brushless DC motor (from an old record player) for this and it's pretty efficient. I've taken one I've had fro MANY years and put an old microwave fan blade on it and attached the contraption to an 1/2 inch PVC pipe and stuck it high in the air. It made about 14 V - 19 V easily without a load.
This will be useful for my project. Thank's a lot.
Theoretically, could a few small and virtually disposable generators can trickle charge an EV or house battery system?
The energy you used was more than it created. Kind of like the fusion test at Livermore.
We missed something. If the turbine is configured to suck air from each end of the turbine, opposing forces would neutralise all torque forces upon the turbine drive bearings and drive shaft. In effect, using high-volume vacuum pressures to drive power devices
Could you please, Robert, run that tri-blade Archimedes screw in reverse to turn it into a propeller and do a whole episode on this propeller concept’s performance? That means the blunt side will be the front that scoops the air in and the pointed side becomes the back where the air exits. Use physical bearings, though, rather than wobbly magnetic ones for this experiment. I imagine it will be super quiet and very efficient! Please. 🙏
Is the goal to stop the bouncing?
If so why dont you go with the bounce? The two wavy pieces or all components could potentially go with tide ?
you are a great teacher
That was interesting. Thank you Robert. :-)
I think you would do good as an infomercial pich man. You got good energy and great punchy voice.
Love the vids 🥰🥰😊😊
Wow, thank you
@@ThinkingandTinkering you are most welcome Sir ☺️
Thank you for all the gizmos and ideas you try to expand all our ideas 😊😊
Thank you for sharing this piece of information.
Fabulous. Thank You.
Cant wait for this to become the next new breakthrough in turbine disign.
"Insert toroidal prop joke here"
Many wind turbines have one problem: high winds. As the wind speed goes from a normal speed to 80 - 120 miles per hour, the turbine spins so fast that it can be torn apart. In the large 3 bladed wind turbines the blade changes position relative to their mounting hub. The more the blades rotate relative to the hub the less force the wind can exert on the blades. When the blades are parallel to the wind direction, the wind turbine stops rotating and the high speed wind won't destroy the turbine.
I think they have brakes to get the speed down
Focused magnetic field in the right angles to spin blades = perpetual motion. More strength, more pull, no resistance.
What happens if you combine the 2 designs. Use the "pen style" and then use opposing magnets at each horizontal end of the turbine?
First time watching, thanks for the upload :)
Very very cool Robert, love how fast you can bang proof of concepts with a 3d printers, imagine Tesla with one of these, instead of designing and hiring out contractors to build something, Inventing has never been easier, tinkering has never been fast and efficient.
t s astounding how 3d printing is helping - to think only a year ago - less probably - would have been in the '3d printers are rubbish camp' - how things change!!
@@ThinkingandTinkering I was using 3d printers 5 years ago and it was like "why spend so much time building and tinkering with the 3d printer when I can just build what I need faster than making the printer work to make it:, but now they work out of the box and with filesharing and easy cad wysiwyg web programs, you would be insane NOT to go the way of the 3d printer, the day of super speed inventioning and prototyping is upon us, nice to see you at the forefront :)
Nice guy. Joy to watch
This might be a waste of magnets but my thinking on the magnetic bearing with the pen is to add repelling magnets all the way around and tighten them up closer together to reduce the wabble.
Magnetic bearings work best in a vertical orientation and the method of holding the bearing in position requires correct placement of the magnets to have an attract and repel setup. I made one as a demonstration using an old CD storage case to make the bearing mount and the spindle as a proof of concept that had the desired effect of both working and shutting up those who claimed it couldn't be done.
done videos on it in vertical too mate
Same in the Netherlands right now along the coast. May take another week to change back into something remotely resembling summer
An upscaled and refined turbine like this plus some good bellows may make man powered electricity feasible.
I've asked the question on multiple videos of people demonstrating this floating axel setup: Can the point contacting the retainer plate be replaced with 2 opposing force magnets, making it a contactless axel? What fails if the axel has an outwardly facing south pole and the retainer plate has an inwardly pointed , opposing, south pole? One would assume that the 2 magnets could be arranged so that the tip of the axel is magnetically floating above (beside) the magnet on the retaining plate, making the entire axel a truly floating mechanism. Seems logical in my head, but I've never performed the experiment. If you have a few minutes to set that up, it would be great to see the results.
the simple answer is no - the explanation of why is long - which is probably why you haven't had an answer yet - but the simplest thing is try it and see - good luck
Hi Rob, been noticing lately some audio lag/out of sync soundtrack, anyone else notice anything? no big deal though
Well, that prop design in a chamber could be used to propel a boat I think. But in reverse. Brings in large amounts of water, compresses it and ejects it to the rear. I will not say it would be quiet underwater.
Perfect ,all the best .
Brillant as always
If i did that much huffing and puffing i would have passed out from hyper ventilation😂
Ever thought of using using a CDROM moteor as a generator? All the ones I've used in the distant past, used a three phase winding so you need a 3 phase rectifier. Used to connect it to a modiified Fan to drive the gennie.
Just curious... Are You aware of electrogravitics? My dad worked on it with TT Brown. The piece featured on My channel discusses it.
your enthusiasm & energy are contagious, keep up the great work
Having a disk of magnets impairs the flow of wind however. Still a fun experiment.
use a convex shape of magnet to create a cavity for the turbine to be held in. will reduce a lot of instability.
I recall a man (but not his name) that built very high-speed gyros that had horizontal shafts on magnetic bearings. They were spun up (charged) to well over 100,000 rpm by an integral motor-generator, and all of it was sealed in a casing vacuumed down to prevent drag on the wheel and other spinning components. Once they were at full speed, they could generate electricity to power such things as cars and satellites.
The trouble with cars, is that they hit bumps in the road, which is hell on magnetic bearings. He could control the gaps, both longitudinally and radially, with a microprocessor and gyros to sense the bump, to increase or decrease the power of the magnets in the bearings. His biggest problem was containing the detonation of a large wheel at high rpms if one were to fail. He also had issues with the speed of the sensors and the reaction time to power the magnets. Processing speeds and sensor quality has increased greatly since then.
I believe that at least a few satellites were put into orbit to test the power packs. Obviously, they would be recharged by solar cells, since long extension cords are very expensive. 😉
Interesting, as i was watching this i was thinking about how most people in subdivision and such are forbid from having a wind tubine.
Then the idea popped in my head of how the air flow in an attic works .... cool air in the soffit and hot air out the ridge vent .....
Would it be possible to put a turbine in front of the ridge vent if we could get them to spin freely enough to produce energy and not be seen?
how about running the current back into a small electromagnetic floating bearing to strengthening it. Till a certain level of power level is achieved. then release the remaining to power the light. while still strengthening the bearing. achieve high speeds, more stability?
I love all your inventions, and the joy you bring to these videos. When the "Mad Scientist" is the good guy: "I'm going to bring unlimited clean energy to the WOOOOOORLD! HAHAHAHAHAAA!" Meanwhile at the Justice League: "Well now he's just making us look bad." 😉
Oh to have a workshop kitted out with all the semi-random stuff that you have! I don't have the room to store things on the possibility of them being useful!
Thankyou for this, it is definitely heading in a direction that interests me. Now to hunt down some relevant ideas and do some cogitating.
What about to make a similar one in a vacuum chamber without air friction ?
On the ballpoint bearing model, would adding magnets on top reduce the wobbling enough to make it useful?
It should serve to make a more strongly defined local energy minimum afaics.
Very interesting, thanks
At 1:32 all you need to do is clamp the rotating shaft with another 4 magnets above the shaft magnets this should stop most of the wobble. Basically duplicate the bottom plate above the shaft. Ultimately you should clamp the rotating shaft in place totally with 10-12 magnets and no ball bearing the only friction would be with the air.
If i am reading your proposition correctly, that wouldnt work.
It has (unfortunately) been mathematicaly proven that levitating an object using only dipole permanent magnet is simply impossible. The best you can achieve is a meta stable sysem (basically as stable as a lead pencil resting in equilibrium on its sharpened end), which would immediately fall and break as soon as it'd start moving.
Lovely, very intuitive idea, but unfortunately physically impossible until we discover permanent monopole magnets 😞
I used 4 magnets....2 on bottom 2 on top (not symmetrically spaced) to help dampen the wobble. It does work...I can spin my horizontal magnetically levitated motor to 2500rpm and she runs pretty dang smooth. I even have an axial flux rotor attached and I can get the stator very close.
@@Dave_D. Im assuming you still kept a point-contact tho, like the ball-point bearing the video shows. Im specifically refering to a system that would achieve 0 degrees of freedom from magnets only. Using mechanical joints and bearing, it is as you could say staggeringly easy to achieve it.
@@colinlapierre-fecteau316 I thought @kevin was simply talking about the shaft rotation bearings....where Robert's 1st example showed just 2 underneath. If you add 2 more on top - to form more of a complete circle, it helps hold the shaft stable while it rotates, as there is forces acting on all sides, not just the bottom. Yes, I still have a pen ball point as my contact against tempered glass. I don't think it's that easy to eliminate the single point of contact and use magnets...I think I MIGHT have seen one example where he claimed to have done it....and I've looked at a lot of stuff on levitating a rotating shaft. Search for 'flywheel with magnetic bearing' (synterr)....he has 4 magnets and it's so smooth. He does have contact points on both ends...I only have 1 and my shaft is 2 feet long.
@@Dave_D. that's interesting!
Its true that what i've seen said was about a static equilibrium, so it might be possible to have 0 contact as long as it keeps moving..
In any case I'll be sure to watch what you recommended, it seems like interesting stuff!
Always cool stuff, Thanks!
cheers mate
I love the idea. Compared to your model, an actual magnetic bearing turbine would need a perfectly balance turbine. Yours was not balanced which caused friction from the wobble to slow it down. I would love to see a perfectly machined/balanced replica of this!
Even if you had perfect balance, I think a direct source of wind not perfectly centered could have the same effect of being off balance. Maybe it could be machined perfectly and have a funnel directing airflow to the perfect spot?
Curious as to how it would work if the Turbine was reversed so that you blew on the big end like a Jet Turbine?
Hopefully when you get into the 2030s I'll stop having my brain think the video title references a year
Cool, the only problem is that the magnets lose strength over time. You could scale it up, and produce electricity, but once again the magnets would need to be replaced regularly!
That would make an excellent design for a water turbine, have you tried yet ?
Spins good, does seem to wobble a bit though! The pen is mightier than ..., like your new way to utilize it!
yeah i saw the wobble too - hmmm
@@ThinkingandTinkering Yes, but I know U can solve it, waiting' 4 Ur fix.
Is it possible to exploit a system like this with air bearing, i don't know how to impliment this mechanism of ultra low friction but I think air bearing can be exploit more
Very cool! Just curious, how do you think this would work in space? But since we can't go there on a whim, how about fully submerged underwater? Like if you placed this in a fish tank and spun it with your finger. Would it work? Would the stability issue be solved?
Imagine putting it in an exhaust pipe to generate electricity, probably won't save the world, but every little bit helps
Ha good thinking. I had the exact same idea 5 years ago with this exact turbine except I had it hanging vertically above my living room radiator from a screw and had the bearing attached via a tubular magnet glued to the turbine. When the heating came on the turbine would spin. Hardly any resistance this way, the slightest breeze and it flies!
Very creative.
Enough to charge a battery?
Why couldn't you take a cone magnet and use it for the end and machine a female to the cone tip that was the same polarity either as a magnet or a piece of iron with a magnet attached to give it the polarity desired? The cone "should" provide a constant on both ends without the need to touch on either end. This would remove all drag. You could even stand it upright and further reduce gravitational interference.
Have you scaled this up? Brilliant.
Have I just watched a new measure of power invented? 1 RMS = the puff power required to light an LED for X amount of time.
lololol
awesome, being archemedies turbine it will auto cock itself into any wind also :) i can see small varients of these being included on e vehicles to scavenge power it ofc can never equal the power needed to move it along but with so little friction & being self cocking design without need of extra power i think it could be as useful as pasive breaking systems are for energy reclamation
Watching Robert blowing while trying not to laugh is so funny🤣
I just subscribed with my nose.
bright ideas...make happy!
i think part of that giggling 4:36 was inspired by the hyperventilation.....i speak from experience, but it's an avocational hazard of having so much fun tinkering.
