This is such a cool project.
This is such a bland comment. Especially coming from someone as talented and intelligent as yourself. Edit: for all the pissheads below that don’t get the point of my comment, it’s a spambot
Such a cool KZheadr visiting an equally cool KZheadr.
Why doesn't white phosphorus reacts when stored with water ? But it can react on the oxygen in air. I saw it from one of Nile Red shorts
Yes very cool, amazing
@@Monkey_D_Luffy56 I’d guess it can’t because water is too inert, and under normal circumstances the phosphorus has not enough energy available that could break the covalent bond of the water molecule and free the oxygen. Someone with more sophisticated chemistry background please correct me if I’m wrong.

@@drink15 no, dw
I am glad to see you here Destin.
I had one of those levitating desk toys growing up. Mine had LEDs built in that were driven by the spinning of the toy, so it never needed batteries and would illuminate with bright red stripes when spun. The setup you've engineered is pretty awesome!
I wish this video was available, when I studied electrical engineering. It would have made understanding the concept a lot easier. This is hands down the best explanation of how a full bridge rectifier works, I've have seen. It's rare to see someone who can simplify things so that they are understandable yet not simplified so far that they are essentially wrong. Great job.
If you need this overly simple video to understand bridge rectifiers as an electrical engineer then god help us.

If Electroboom has taught me anything it's what a Full Bridge Rectifier does.
Don't you mean to say... FULL BRIDGE RECTEFIER!
Exactly, it's not some dumb single diode rectifier
Actually I heard him saying it over and over again but it wasn't until Tom explained it that I knew what it does
Ikr 🤣
Full bridge or no bridge, all the way home
wow this video alone taught me exactly how an alternator generates electricity and how a rectifier can make direct current.
seriously i finally learnt rectifier working here
In 1995, I was a young "lad" just visiting a foreign country (England, London) for the first time, and wouldn't you know, the device displayed @ 1:38 had me captivated. I was only 15, but between this device and some lego's before a trip to Bath... amazing life experience. My grandmother took me and for some odd, but likely predictable reason, this kind of video triggers in me a great sense of appreciation. I wish you the best Tom. Lots of love and admiration for your efforts. I just hope you spend a fraction of a time wondering what some of your viewers have experienced... because it's pretty damn amazing to share these kinds of experiences.

I am starting to think Tom is obsessed with flywheels
Nahh I don't see the obsession?? 😂😂
The mind learns something new and then extrapolates
Sir, you are wrong. He surely hates flywheels.
Ofc he is
It's a passing phase. Just like how he obsessed about pneumatic contraptions for awhile.
Love it, you made an easy to understand flywheel mechanical battery and by levitating it you decrease the maintenance cost (lubrication) and reduce the friction.
This is what a future home/house energy storage system looks like.
Not likely.

Tom, This is the best video I've ever seen. Your entire presentation and explanations at each step are spot on and easy to understand. Great job keep up the good work.
I cannot express how inspiring this video has been. I’m curious if you ever measured the power you could get out of the generator for a given flywheel rotational speed. It would be great to see you take some measurements (volts, amps, rpm) and then optimize this similar to the rail gun optimization. Best regards!
Che utilità può avere quel generatore? In altri termini: le bobine frenano il volano o no? Se no, l'elettricità prodotta potrebbe essere usata per muovere a sua volta il volano...
Well not much energy is captured in such a small flywheel, when rotated by hand. To get a better feeling for how much effort a human body must spend for an every day job of an electric device. There is a video on KZhead where a cyclist is making a toast using his legs.
I can never hear the term 'full bridge rectifier' without hearing electroboom say it in my head
Yeah I was almost disappointed he didn't reference Mehdi when he used the term :'D
U mean a FULL BRIDGE RECTIFIER?
Same here, but he elaborated the concept more comprehensive
The common name is "full-wave rectifier" (FWR). A lot of power is lost in the diodes of an FWR. Transistors can be used instead of diodes with much less loss. This is called a synchronous rectifier.

FULL BRIDGE RECTIFIER!!!
You know electroboom right?😂😂
I was expecting the comment to be posted by electrobook
THE MOTHER OF FULL BRIDGE RECTIFIERS‼️‼️‼️‼️
Erik Johnson is a time traveler! 🌈
Whoa easy myg guy..
I believe the flywheel alternator can also function as a brushless motor with a suitable brushless controller to spin up the flywheel.
And you could "charge" the flywheel when you have surplus energy and then use it when you have higher energy demand.
First time I've seen anyone explain a full bridge rectifier - so thank you! This contraption makes me thing of old foot powered sewing machines... and how that'd go.
The good stuff is called “turned ground and polished”. It’s high quality, exact measurement on the o.d., steel rod. Try that for your axis.
get this comment more likes and replies so that tom can see it!
May be it would have been better to use a bad, unstraight axis and achieve higher rpm than resonance. After resonance frequency rotor would balance itself. With bad axis resonance frequency is lower so it is easier to overcome
still wouldn't work if we warp it when trying to insert the flywheel
@@oadka No you didn't even do any capitals or ask nice. :P
Also wondering if he could use opposing force magnets on the ends of the rod to locate it, eliminating all points of friction.
"This method of levitation was heavily inspired by this small toilet I bought off Amazon."

@@HelloKittyFanMan. I create my own reality. You should give it a go!

'crocodile clips' Makes sense, no reason why they have to be alligators

I lost it when he said it tho.

@@ooxRAINB0WDASHxoo No. In the UK they are called crocodile clips.

Next trebuchet build coming up ?
Flywheels are kinda tricky in vehicles due to conservation of angular momentum.
Very nice concept. I must say, your explanation on how alternator work is the best I have heard so far.
Could this be hooked up to some type of sterling motor that runs off temperature difference ??? That would be an exceptional machine for sure
Hi
i think F1 engineers worked on this.
Oh yes do you intend to use magnetic levitation bearings on the hot air engine ?.To be honest I have a feeling that the magnetic bearings may be no better than ball bearings and of course the latter are much more constrained and keep an errant flywheel in check. Air bearings may be better but they do require energy input. Toms flywheel is only working at low speed as I suppose a hot air engine would.

For those wondering: the alternate current after passing by the bridge rectification will come out as "waves" of positive energy. Those waves are not exactely direct current because it has valleys. Tha'ts what the capacitor is for: storing enought energy to fill the valeys in the time btween waves from the bridge, creating a proper direct and stable positive current.
Nice
True but it is however exactly direct current. As long as the current doesnt reverse its always direct. No matter how deep the valleys or how high the tops as long as its not crossing the 0V line its always DC.
@@fluke9972 you are absolutely right. Poor choice of words from me hehe
If only my electrics teacher could have explained it this simply
Why are the lights still flickering if there's capacitor?
One of the things I've learned is that nearly all the work done by the fly wheel is from the mass at the outer edge. You could cut away much of the inner mass and still be good. As far as replacing the shaft, try cutting it off and drilling it out. Most drive shafts aren't force fit. Try a design where the tolerance is such that it's locked in by a set screw or a key.
This. The theoretically ideal flywheel has asymptotically-close-to-zero mass and an infinite diameter. One could store much more energy by adding a ring of steel around the edge and remove the same amount of mass from the center.
@@LilMissMurder3409 actually wrong on the mass part. It's the momentum of mass that keeps it going. The ideal has an extremely high mass concentrated in an atom thick layer with no mass between the "ring" and the axle beyond what's needed to connect the two. Without mass you could not have momentum and cannot use that momentum to do work. The true challenge with the mass is figuring out how much is enough to do the work without requiring too much work to get it up to speed and keep it there. Infinite mass may seem to be the ideal until you realize that it will take infinite energy to move it. Near zero mass seems the ideal until you realize that it can't perform much work. The true ideal is somewhere in between the two extremes and varies depending on the work that needs to be done in combination with continuously needing to overcome friction.
@@ianbelletti6241 isn't aluminum a poor material choice for the outer ring then as it's fairly light? I suppose you would want to use something denser like bronze with carbon fiber spokes connecting it to the drive shaft?
Did you try measuring how long it spins with and without a load?
I wondered that too. The greater the load, the fewer revolutions. If you take a ton of rechargeable gadgets on a road trip, your fuel economy will suffer.
@@waspbloke why is that?!

He made a frame with 80/20 that was 2"x2" and other sizes for a machine that wrapped foam with material that conducts electricity. The newest cell phone, plasma televisions, and even antennas (for GM/NorthStar) use these technologies. Everything needed to make the flexible copper-plated material except the foam was made in-house. Afterward, I was tasked with making maybe30+ more in my six-year stint. They shipped these inexpensive foam wrappers all over the globe. Retired now for 15 years.
Wow your explanations are simply awesome! So glad I found this channel
This was the first time I've ever understood how a full bridge rectifier actually works.
Exactly! Same here.
6:21 notice the arrangement of the diodes, and the source and load. You can use a bridge to protect the input of your project from reverse polarity, If the battery was installed "the correct way" the power would flow properly. If the battery was installed "the wrong way" the power would STILL flow properly. Unfortunately, there is some voltage loss. Bridges typically use diodes that lose 0.7V each, so 2 * 1.5 = 3V loses possibly 1.4V If you build you own bridge using Schottky diodes the loss is less 0.3 to 0.4V. en.wikipedia.org/wiki/Schottky_diode Note: I previously referred to 4 diodes, which is incorrect

Since I'm the "push it until something breaks" type, all I can think is "I wonder how fast it'd spin if he spun it up with an air compressor..."
I was thinking: how much more efficient would it be operating in a vacuum? We need both questions answered.
yes
@@ericlotze7724 i dont think they use hydrogen though. Kinda explosive.
@@bertjesklotepino This is overstated in the public, and MANY industrial gasses are explosive/flammable (see petrochemical / crude oil distillation industry etc) It is all about safety systems etc, and even then pressure, and fuel-air mixture/ventilation are factors (a propane stove blowing out a match in a shed vs outside with a gentle breeze, which will produce more of an explosion when the next match is lit and that cloud forming ignites etc) Hydrogen-cooled turbo generators are a similar application. People probably tend to use helium, but hydrogen is "faster" if that makes any sense (granted i am not an expert, just a nerd, so if anyone has more on this subject i'd love to hear more (i *love* FES as a concept) )
@@I-0-0-I Commercial flywheel backup systems are in vacuum cans. Quite efficient, a little more expensive (if I'm remembering correctly the quote we got a year and a half ago) than a battery back up system of the same capacity. On the other hand, you never need to replace your UPS batteries!

@@samykamkar you just changed the game forever
I really want tom to short the whole thing so we can see how induction brakes work :D
It's pretty close to that at 13:10. Notice how it starts wobbling as the motor stops, I think that's due to uneven braking resonating with the magnetic bearing.
Throw in a mechanism to drag start it like a lawn mower to juice up with extra spinning power, throw on optical rpm counter to know how much energy is in the system at any one moment, and measure the braking current, figure out the force and efficiency of the braking. Bonus. Make a small electric engine for spinning up the disc, charge up a capacitor for braking after it's hit max rpm and use the capacitor to run the electric motor again. Figure out the roundtrip efficiency of the energy storage system from the drop in rpm
As soon as you draw power, it does that. It doesn't need to be a dead short.
@@sbkenn1 Yes, sure but the higher the current the more visible the braking
In my opinion, you could increase your coil count from 4 to 8, by slightly reducing the size of existing coils, while keeping the same thin gauge copper wire. This would keep a more stable current and should give even more voltage output. Then you should hook up a low voltage arduino board to it that pulses a motor that would spin the flywheel automatically. I would be interested in seeing how these changes/additions impact the overall design and efficiency and whether or not it would work.
The goverment might have gotten him
To make it self-sufficient? This is what I proposed in addition to putting it in a vacuum chamber to further reduce friction.
@@SeynGod you wouldn't dare break the actual laws of physics now would you
That would make it a perpetual motion machine which is not possible. The only way you can have a machine that recycles energy like that is to have a 100% efficient transfer of energy which is almost impossible itself. And that's if you don't extract any energy from it yourself. So the arduino would have to have a separate power input source, which kind of defeats the purpose of this contraption which is to be an easy and efficient hand crank generator. The arduino could signal for a motor using external power to spin it using the power from the generator which would work kinda like a car engine's alternator and battery
William John Macquorn Rankine would have a field day with that proposal- An he was standing on the shoulders of Giants in 1850! He helped to more fully develop the Laws of Thermodynamics- a great Wikipedia read… I do Love this display of how power is generated! Mr Stanton has done an excellent job!!
I watched this when it came out and tried to put together what would basically be infinite rotation energy. Obviously easier said than done. I lost my notes for it but it basically had to do with bismuth, magnets, fly wheels and some other stuff. Great video btw.

Honestly I learned more out of this video than I did all my school years... Yes, I know I'm to blame but still, you really make it fun to learn!
Try configuring the coils into three phase this will increase the voltage .you have options of “star” or “delta”
Now you need circuitry to reverse the alternator, making it a motor to spin up the shaft. This turns it into an actual battery, storing external energy.
How about: wind powered flywheel
Would that actually work? I'm very interested to see an actual like demonstration
@@certifiedpossum1638 Yes! But there could be the possibility that it ends up being too heavy to work very well.
@@Sam-fq5hc No the torque will be a function of the surface area and geometry of the blades. With large enough blades you can power something extremely heavy. That is why industrial wind mills are so freaking massive and ugly
In the current configuration it is still a battery, the external force is just him. It stores the energy he inputs as kinetic energy and the alternator outputs that as AC
WOW, that slow motion of alternator powring LED at 11:17 is so SATISFYING to watch!
Great explanation and presentation (also dialectical way of lecturing, 3D visualization). Thank you!
Im making this with some minor alterations to make a fun desktop Pomodoro timer! One thing I am focusing on is controlling the length of time the alternator will run. When the flywheel is spinning, LEDs will light up and as the spin rate decreases the lights will dim. When the flywheel stops the lights go off and that indicates it is time to take a break from work!

>Flywheel powering small motor Well, that’s the strangest gear ratio setup I’ve seen
I feel the overwhelming need to get myself a version of this with a straightend shaft, and a geared down crank shaft that disengages as soon as you let go of it on the right site to spin it up to really high rpm
A one way bearing driving the shaft would work. Or even better, use magnets to drive it and pull the magnets away somehow when not turning.
@@ADBBuild perhaps a centrifugal clutch? You could gear the output of a hand crank to increase the RPM, and the rotation pushes magnets out to engage the coupling. When you stop turning the magnets retract and decouple.
Like pedaling a bike except magnets on all gear teeth
I'm disappointed he didn't use the generator as a motor.
Love your fun concept! measure your drill battery charge level before and after you spin it up, and also measure the total output from the fly wheel all the way to the point it stop spinning :)
If you had slight friction stability on both ends and a ring of magnetic levitators on both sides of the fly wheel, it would be more stable and be able to go much faster. Your frequency is probably really low too but that's obviously just due to instability. Great video!!!

Now you just need to make a magnetic gearbox to rotate the shaft. Pretty amazing stuff 😁
To straighten a shaft in a lathe : spin at around 500rpm. Start with about a hands width protruding from the chuck. Check for wobble and pull the bar towards you. You will feel the bar vibrate as you pull the bar past centre slightly. Do it the right amount and you will overcome the tensile strength of the material just enough for it to remain on center. Pull the rod out another hands width and repeat. Always check by rolling the bar on a known flat surface. Wet hands for extra lubrication.
Ummm, or just use a dial indicator. My old boss taught me the quickest way to get something roughed in is to use a sharpie and brush the high spot as object spins. Benn a machinist for about thirty years. His best bet is to cut off the shaft , drill out the center, and bush it for a new shaft. Pity it warped on him.
I would say never put your hands near a lathe spinning material at 500rpm. Better to buy silver steel which should be true

He should make a much bigger one on a bike frame so you could really get it going with pedals. That might actually have some real world uses like charging your devices in a power outage.
My vote is for AVE
I’ve watched this video a couple times and I’ve always wondered if how it would perform if you used materials that didn’t interact with the magnets. The steel is obviously ferrous but the aluminum also responds to the magnets in the same way that copper does by creating eddies. I’ve also been curious about what would happen if you spun the flywheel a lot faster with a drill or something.
I can imaging a spinning Christmas tree powering its own lights! Very elegant demonstration, btw
I always hear "FUUULLLL BRIDGE RECTIFIEEER" with electroboom voice in my head
No reply’s?
A 4 diode bridge is a full wave rectifier.
Lmao same.
YEEEEAHHH!
THE RECTIFIER
This was much cooler than I expected. Love the demonstration of the full bridge rectifier. I had no idea converting from AC to DC was that simple.
Fortunately, I learned that 40+ years ago. With coils that are at different positions, they will produce AC peaks at different times (phases). In the 1800s they found out that 3 coils making 3 phases can provide smooth power without wobbling, which is really nice when the flywheel etc. all weigh multiple tonnes. Converting 3 phase AC to DC just needs an extra pair of diodes for the extra input wire.

@@johndododoe1411 a Hex bridge!
the reverse is much more useful and complex, inverters are sophisticated thing
@@elysonpanolino1162 what makes the lines on the road sizzle under the big power lines? After the rain.
There are some many things that I can appreciate about this video, thank you!
You should make one of these connected to a bicycle wheel hooked up to headlights or something. super entertaining and educational channel. love it.
“on my grandads lathe” is so gratifying

Thank you for all yout videos. I have so much fun watching them.
This is pretty quality, thank you my friend. Going to try this for my porch light, for fun
This description of a full bridge rectifier was one of the clearest I've seen. That was really well done!
The French telephone system used this to provide emergency backup power more than 50 years ago.
Hospitals use these today, IIRC, to provide steady backup power for life supports etc. during the first few seconds of a power outage that their main back up generators take to power up.
@@epamaarainenroina220 Dont they use a diesel or petrol generators?
Use of the internal combustion engine should be on the way out. Solar, used to heat molten metal with external combustion engine hopefully developed soon and too use widely.
you could sandwich as many coils and magnets as you want and use more negative opposing magnetic fields to make it so the shaft does not have to touch anything and can float. you can also seal this in a low pressure chamber to achieve near zero resistance spinning and full efficency
Excellent demo of a system of energy transforms and storage! WOOT!
I wasn't expecting to gain an understanding of Full Bridge Rectifiers today, but here we are! Thanks!
Yeah, this makes a lot more sense than my physics textbook did.
Not to put too fine a point on it, but the proper term is "Full wave bridge rectifier" for the device made up of 4 diodes. They can also be purchased as a package with 4 leads coming out. "Half wave bridge rectification in the case of this circuit could be accomplished with one diode.

Same
I still dont understand diodes at all
