037 A Flywheel Generator

[@gerryjamesedwards1227]

I've been fascinated by flywheels, ever since helping to start an old Stuart Turner engine. You have to spin up a massive flywheel before releasing a clutch to turn the engine over. It takes longer than hand-cranking a (very) old car engine, but it gets easier and easier as it gathers momentum and doesn't need a special grip to avoid a broken thumb!

[@Eaglepass]

I very much can appreciate all flywheels. Thanks for the smiles Professor. Great recipes at a fraction.

[@Chris-bn1bn]

I had an idea a while back, but never found the time to verify it. 2×2 meters plywood .25" made in an X .75×3.5". Put 5 kilo's at each end of the plywood. If you're creative, use something aerodynamic for the weights. This confifuration will balance easier which as you know, robs lot's of momentum. Now if you use magnets rather than bearings you lose more friction. I don't need to tell you how torque would be generated with all the mass at the perimeter. If you're curious, I'd be quite excited to see what potential this design produces. I'm certain that you'll have your own modifications. Thanks for your terrific channel!

[@IstasPumaNevada]

Source of energy loss is not only bearings of course, but also air resistance/air friction. And the losses due to air resistance/friction increase exponentially with faster rotation speed while the bearing losses increase roughly linearly. With good bearings at high speeds I would imagine the losses to air resistance are much higher than from the bearings, so it's always a good idea to make sure the flywheel itself is as smooth and uninterrupted in shape as possible.

[@thesentientneuron6550]

19:20 Not sure if it's been answered already but I worked it out to be 6 rotations per second (5 frames per rotation at 30 frames per second) which is 360RPM approximately. Edit: Have you thought about driving the coils from a source to spin up the flywheel? As in, use the same generating coils to also store energy.

[@_SimpleSam]

You want the flux perpendicular to coil. So, I would think leaving the floor of the rim uncut, and cutting the edge of the rim to bend out and around then in to the center might be better. The idea being that the north south flux travels into the tab, around the floor of the rim, and then back down the other side tab to the next door opposing magnet. Since the tabs from the rim wouldn't reach all the way across, it would probably make sense to use the entire rim, and stagger the tabs, either side. I would think that arrangement would make a world of difference. That make sense?

[@beautifulsmall]

Taking the flywheel to the extreem is the axel-less flywheel with all the weight in the outer ring and the drive coils completely encircling the rotor. The ring motor, which Ive prototyped but would work best in space. Always a pleasure to watch and learn.

[@SSGrille]

I find your curiosity so contagious. It is the best. I have always wanted to modify the rear wheel of my bike to a flywheel. Only hiccup would be trying to stop, and turning, but wonder how fast a human could get up to by slowly adding power to it, then having to only add tiny amounts to keep it going. Could you mount an 8’ dia solid machined steel disc into a frame with a set of gears sized to get that spinning, apply that to the drive wheel, and maintain that spinning mass? I know there is such a waste of effort to get it to speed, I’m just curious what happens.

[@RyanJBarnard]

Generation at the rim with a flywheel is a truly neat idea.

[@jameshughes3014]

You make it look easy. That is one big project and it was great to see it come together.

[@TabooRevolution13]

I got an idea Robert. Put the same motor on both sides of the flywheel... Use one as a generator to power the original motor with a capacitor. Now on the edge of the flywheel... also add magnets back and forth positive / negative with a coil that also powers the original motor!

[@paddy2661]

Awesome Rob yep I was going to comment half north half south but you tested the theory , I have a 40 year old bicycle dynamo (lights generator) It's feels like 50/50 north / south but possibly 4/25% 6v 3watts output. Your flywheel motor generator setup should become the new electric car motor design , more torque the bigger the wheel (hub motors) Love it this is cool thanks Robert Washing machine pump motor has 50/50 magnet on shaft approx 50mm long by approx 20mm hopefully fits inside microwave motor coil if so could mount 4 microwave motor coil side by side and have pump magnet internally , with iron bent over on coil. Have to check fitment myself.

[@paddy2661]

@@oakmot5477 yep spoton it would have to be a manual to keep motor momentum going all the time , but at the lights stopped atleast there's no power required for few minutes. One minute uphill would be ok , regen would need a separate generator as the flywheel energy would keep the car going and cook the brakes. .

[@markhodgson2348]

Feed output through a microwave oven transformer nice to see you teaching people

[@velcroman11]

Power = voltage x current. I think you will find the arrangement of the magnets will produce the same output power regardless.

[@AllSeeingHeart]

So, with a large enough flywheel, spinning at a sufficient speed, we can power a whole village, or city, efficiently - cost effectively? Tax free or lower cost power? I apologize for critically thinking, but I imagine when I think of such things as 'free energy', or in the least, more cost-effective energy I think of what you show in this video. I imagine Nikola Tesla imagined such 'nonesense' when he thought he could bring wireless 'free' energy to the GoOD people of the Earth; but his big daddy did not agree since profits would be minimized when regular people can access "energy" without paying for it. Hence, the "power" struggle WE live in 2023, and soon to be 2024. Strap in, prepare folks, more fireworks coming. K33P UP the GoOD Work Sir. Strength! GODsp33d!

[@joecool7165]

What is you use magnets for bearings instead of bushing bearings? This should cut down on the friction quite a bit. The trick will be balance, avoiding sticking.

[@dougwardle2175]

So what would happen if you wound the coil around the flywheel and placed the magnets on the outer rim??

[@krishampton8163]

You'd have to come up with a fancy way of pulling power through the axle because you wouldn't be able to connect a couple wires to it

[@diyathomevn]

I've been fascinated by flywheels ever since I helped start an old Stuart Turner engine. What is this for?

[@stephaneislistening6103]

I'd love to see here a battery that can replace these catching fire in cars. I was sure it would arrive here years ago. Is it simply a bit delayed?

[@DavidLlewelyn-p2w]

Is it correct to assume that the outer rim is actually a 'single turn primary' for the outer winding ?'

[@jcl5m]

Hi, i've been curious about fly-ring concepts vs fly-wheel because the kinetic energy proportional to square of the square of radius and mass distirbution. YT keeps recommending your videos when I do my background research. I would love to get your thoughts on the idea if you are open. Much of the mass of the unform flywheel is near the middle which doesn't contribute as much to the stored energy. Flywheels which have thinned out centers are limited by the tensile strength of the spokes are higher velocities. A fly-ring in tension , perhaps even supported externally would optimize mass distribution, radius, and potentially support higher velocities. One challenge is a low-friction hubless support system for the ring. If a modular ring support were possible, it would allow scaling to very large rings. Would working on a project like this be interesting to you. I might be willing to fund the prototype/exploration since I haven't found much information online.

[@rommelfcc]

@TNT Omnibus Robert will you make a permanent magnet bearings for the flywheel?🎉

[@stevestogsdill5791]

With the flywheel bus as diagramed above, does the flywheel have and additional benefit of gyro stability to the bus? Also, isn't this the tech behind F1's KERS units?

[@VeniceInventors]

Two variants I know of were used on Swiss buses, the one on the diagram @4:40 which powers an electric motor did spin really fast, and had some strong gyroscopic effect which was a problem because inclines would put stress on the bearings, which incidentally had a bad habit of failing prematurely. What would be interesting to know is if the gyroscopic forces would be sufficient to keep the bus upright when the right wheels are in mid-air over the edge of a mountain road 😀 The other more recent variant with flywheel was used on gas/diesel buses as a purely mechanical way to recover energy from breaking, and getting it back when accelerating. I recall the bus company stating that it saved around 30% in fuel, which is significant. That was in the 80's, I don't know if they still use them now.

[@familygarlick179]

Fascinating the flywheel generater I could not see clearly how you bent the flux by the lugs could you explain clearer please

[@PatrickGunderson]

Wind turbine + gear reduction + Flywheel + ratchet? Seems like a good way to harvest and smooth the output from a wind turbine.

[@jlh2119]

Thank you for information, video and effort you put into your channel. Do you have any completed projects where you use the invention / configurations to actually charge up a 12V / 100AH battery recording how long it takes to charge the battery? It's hard to tell how many of the configurations are folly or would actually work to charge a storage battery in a reasonable amount of time? A reasonable amount of time 4-6-8 hours perhaps? What actually works and what doesn't?

[@dondywondy]

Oh no, sir! Now you have started me on a new diversion which, I think, could consume months or years! Ha Ha! I'm thinking of a horizontal massive concrete flywheel spinning on a pointed steel shaft riding in a lubricated steel 'divot' in the floor. Then: how to spin it up, and how to retrieve the energy put in......... Oh boy this is going to be FUN! Thank you for your videos, we all know it takes a lot of work to plan, record, edit, and post.

[@parrotshootist3004]

a fly wheel powering leds? Wasn't there an old torch like that?

[@onbedoeldekut1515]

You can even combine it with something like a kite-sail for almost limitless power. Or go a safer way by adding a simple separate wind turbine, which could also store some energy just to spin the flywheel, constantly topping their own energy for when the flywheel requires spinning.

[@jimparsonage5709]

Just a thought, why not take the spool of wire and fit a drive cog to it connected it to the bicycle wheel with chain an alternative to concrete poss a roll of 1" lead (old water main) in place of tyre. And magnets fixed in frame arround spool of wire. Same rpm but more constant interaction of NS fields? Poss less work. Lead from any plumber or scrap yard and spools already wound.

[@stevefrancis4949]

What about making a flywheel out of a hub motor into a generator are hub motors the right kind of motor

[@branni6538]

Rob does that led plate have any diodes and capacitors attached?

[@jitone1]

it was hard to see the way you cut the rim. i wonder how long it will spin w/o load

[@colleenforrest7936]

I went to an experimental eco house that used a professional flywheel system. The flywheel was in a vacuum chamber in a near (but not perfect) frictionless environment. Anyway easy home tinker way to put the wheel into a reduced air chamber? I figure any amount of air reduction would increase efficiency.

[@sorryplease5071]

Flushing with helium before pulling a vacuum can help reduce the mass of air left in the chamber.

[@stevegamble4549]

This is wonderful information. It was my first time seeing him.

[@cartertanya1258]

Hi, just a thought . What about using the flywheel to charge capacitors lower power used , but putting on a generator to produce usable power . Capacitor charge to respond flywheel. Just an idea.

[@quanticthinking1517]

i would try north, half north, half south, south for a balanced voltamp output

[@snowstrobe]

Could be used to make power for lights etc in rural places off the grid.

[@David_Mash]

I've been tinkering with the idea of a flywheel with variable mass for a few years. Using fluid. Fluid in and fluid out. Needs baffling.

[@cbobscountrybunker2312]

If you cut apart a automatic transmission torque converter. that might give you some ideas.

@@guerraguerra8621 gravity engine?

[@kevinbuiied]

This has some call backs to a Transverse Flus Generator. For N numbers of slots in the bike, you should have 2*N magnets, alternating North and South. All the Norths should land on a slot at the same time, and as it rotates, all the south should also land on the slots. So in an alternating fashion, all the norths cross, and then all the souths cross. If possible, I would say to have the slot width and the tab widths be equivalent, so that a N and S magnet pair do not cross over a tab or slot at the same time. You want all the north flux crossing over a tab at the same time, while the south flux passes through the slot, and vice versa.

[@justtinkering6713]

Fill the holes with magnets

[@victorbruce5772]

I've long wondered why electric motors has been made larger diameter like 26 inch bike wheel so that power is applied over longer leverage arm than typical electric motor. Could even have dual stator inside and outside of rim rotor.

[@deanrowles3665]

Hi robert, a friend of mine used to have a engine that was taken from a water pumping station, it had a massive flywheel connected to a diesel engine, the engine used to fire about every 30 turns of the flywheel, used hardly any diesel but ran and ran for ages. thought you would like that.

[@carllafrance5510]

Sounds like an old "hit and miss " engine just just when you thought it was going to die it fires back up again the governor controlls the fuel input slow downs adds more fuel at a central rpm shuts the fuel off and coasts till it slows down enough to give it more fuel have a good day

[@andredesouzadasilva5597]

Excelente trabalho, gostei da ideia.

[@glencahalin4786]

Presumably you could also tune the output, volts & amps, somewhat by having 2 norths & 2 souths ( or 4 of each etc ) The thing that I think would be really interesting to explore is decoupling the coil from the cage. The reason being, if you could do that then you could contra rotate the magnets and cage but have a stationary wire electric output no slip-rings/brushes to wear and maintain in a contra-rotating dual wind turbine. My aim there is to get something useful from the lowest wind speeds, with least compromise from medium to higher windspeeds eg have the cage rotating on the lowest start up windspeed turbine and the magnets on a more medium speed one. Maybe even experiment with different types of VAWT eg Drag inner and lift outer ( Ugrinsky centre and lift type outer? ) I know it seems a bit like having your cake and eating it but I'm being optimistic and seeing it more as, eating your cake slowly while the next one's being made ;-)

[@glencahalin4786]

Combining the contra rotating magnets/cage with a tapped coil ( that switches in the full coil above a certain level of volts out ) would further lower the start up windspeed needed to get something out, but not negatively hamper the medium/top speed outputs.

[@lexxsimf2]

At least, somebody in the internet showing how to create an electric motor from scratch, instead "me build electric bike, me buying motor, controller at aliexpress, me screwing it up". Couple of thoughts to begin with.

[@donscottvansandt4139]

Awesome stuff! Got my wheels to turning... lmao 😂 but I think this would work good with hydro power? Because of the tourqe ..

[@historyisfake9153]

wot if you hand crank the fly wheel to speed and now and again did the same and had a motor to speed it up??? ? there must be a way???

[@frederickbowdler8169]

quite good for stalling prevention in cars

[@Tims_Projects]

I think you have cut the holes wrong in the outer. I could do a drawing, but I don't know how to link it. if links are not allowed. Take a good look at the little motor with both top and bottom metal plate back together. without the magnet, look how the fingers of the metal are arranged. The metal ends up wrapped around the from the back (outside) of the coil with fingers inter locking (inside) alternately with an air gap in between? Having the metal fingers wrapped around the coil alternately creates the north south fluxes at the magnet passes?

[@calcoin4199]

Could you just use a bycycle tire filled with sand it would be self balancing theoretically too

[@uncleasshole3787]

Sand and antifreeze. Theoretically works. But it takes out the tire from the inside tire. Sand is very abrasive as it turns out

[@quantumenergysolutions9128]

Seen the new plasmoiod video?

[@Wuuz]

... now fill whole oil barrel with concrete (with bar trough it for bearings) and make magnets to lift most of the weight out from bearings and use bicycle bearings only for aligment

[@jasongooden917]

regenerative braking will stop it though

[@AlienLivesMatter]

Larger front chainring will allow a much larger leverage to be applied across the chain. 77tooth crank and an longer arm is recommended.

[@petevenuti7355]

Im thinking the rim inside the flywheel is shorting most of the magnetic flux! ..., you might have been better with the aluminum rim(even though it will be damaged somewhat by the CaOH and alkali silicates in the concrete).

[@quantumenergysolutions9128]

Mate any chance you can 3d print the Donni Watts gen?

[@zipperdeedooha]

[@William_Hada]

The Donnie Watts generator has never been successfully built by or verified to work by independent institutions or trusted individuals. Most likely a scam. There is money being made from it by bilking investors and selling plans to people that never seem to be to get it to work.

[@Clintimtired]

The best flywheel and I have one is a hay baler flywheel you get the shaft and the bearings in it it's it's terrible heavy and it's already balanced so if you got a old hay baler scavenge the flywheel off it be prepared they're heavy and you get all the hardware with it it's a square baler little one not a big round baler I don't know what those have for anything in them there's a lot of old square balers that are just resting away but the flywheels are good in the scrap yards My hey Baylor flywheel is one that uses belts that run on the outside they're an older model but they're extremely heavy and well balanced

[@karlmccreight8172]

I have been thinking about utilizing the forces that occur when you allow the flywheel to precess in order to get a little more energy back out then with a flywheel with a fixed axis. Its quite impressing when you acellerate a gyrotwister by simulating a precession with the wrist of your hand holding the gyrotwister with the moving gyroscope inside of it. You have to use a lot of force when feeding the gyroscore with new energy to keep it turning this way. The same with a whirling bycicle wheel when tilted.

[@michaelvaughn7137]

Kinda there was a man some years ago now that developed a car that has multiple flywheels at each wheel of the car they spun at 3000 miles per hour the car hasn't been allowed into production because if the car were in a reck it would be like multiple grenades going off at each wheel effected .

The amount of energy stored in this wheel is too small for the size of the device. This means that the effectiveness of this solution is low.

[@Renvec]

15:33 at this point you've just finished explaining and you explained by showing us the device from I'm guessing about 6 ft away from the camera so we couldn't see anything about what you were talking about points going this way or that way which direction of flux went. One of the few things I have to critique about your videos when you're doing talking head teaching moments but you don't explain with the visuals that you're describing you just kind of point at your desk and say this is and it does this but we can't really see it. I've seen some of yours where you get very detailed into describing it and it's why I keep coming back but today didn't come up to that standard. I would generally say keep going with what you're doing some of your videos are very enlightening. Just remember when you're showing us something from 6 ft away that's about 4 in or roughly 8 to 10 cm it's not really visible on screen so you're not really showing us anything.

[@Chris-bn1bn]

Sorry, that was .25"

[@dongraham4760]

Oh dear !! You keep going on about the voltage your barmy projects produce . Voltage alone has never done a days work in history .Current times voltage equals watts , watts is the real measure of work done ! This ill designed "flywheel " producing 10 volts at 5 milliamps or .05 watts and even that is doubtfull because when you measured the current with your meter , that puts a load on the system and I am sure the voltage would have sagged significantly ,approaching zero at the time of measuring so the true output would also be approaching zero . Why ? Because the coil around the circumstance of the flywheel is useless . The magnetic fields from the magnetics need to cut the coil or coils perpendicular to their placement , your "coil" will NEVER work to even extract the smallest fraction of the work put in . The "voltage " and "Current" you are seeing is being generated from the field lines cutting along the length of individual wires of the coil and leaking out which you measure , a more inefficient way of producing power I do not know of!

[@mozpogson3639]

Your hypothesis of the flywheel helping to keep the engine turning is a false conclusion. Note that flywheels have gotten lighter over the years as racing cars have very light flywheels for better performance. Engine speed increases and decreases faster with a lighter flywheel.
