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!

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.

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.

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
Peter goes to Hollywood
@Monkey D. Luffy 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.

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.

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.

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!

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.

Hi Tim I really like watching your builds and listening to your presentation of this field of study. May I offer you a better alternative for efficiency I would have the magnets in the middle then have the coils either side. The field strength of the magnets would induce the coils as they are not very deep in the bobbins. Also maybe try finer gauge wire if you want volts as tesla said make your turns many for volts. I watch countless videos of people not utilizing or being efficient it's like they have too much money and not enough mother of necessity.

Haven't read all the comments, so I don't know if this has been suggested yet, but to further minimise energy loss to friction at the left-hand end, you could use opposing magnets to eliminate the left-hand shift instead. I will accept refinement royalties when this takes off, thanks.

You could add a hand crank to the end of the rod that is able to quickly disengage from the rod holding the flywheel (so that friction doesn't slow it down), that way you could manually get lots of power without using a drill.

This is cool! Like others have said, I bet you could get better performance with a thicker tool steel shaft that's just smaller than a precisely reamed hole in the disc elements, then use glue to fix them... And then at each end (and even at intermediate points) you could use high quality bearings with the grease removed, and lubricated with WD-40 only. Then put the whole thing into a vacuum chamber and get the pressure down as much as possible. I'd love to see a part 2!!

5:52 - You must be pronouncing FULL BRIDGE RECTIFIER incorrectly, the camera didn't shake. BTW, with a flywheel, the energy stored depends on the mass and speed. If you make another wheel, thin down the centre, and concentrate the mass on the outer edge, you will be able to store more energy without increasing the total mass.

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

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.

I think it would have helped to put the magnets out of phase, so the magnets on one side face the in between the magnets on the other side, which once rectified should result in a more even output

The way you visually explain the working of electricity, magnetism, lavitation is osumn and easy to grasp onto and fun watching these things working live in your interesting experiments. It's so satisfying to watch a flywheel powering things around. This is exactly how I'd expected my teachers to be but unfortunately they weren't such enthusiasts and were focused only on our grades and the boring black board teaching.

What a cool project!! Please keep on doing cool things like this. Some remarks regarding turning AC to DC: LEDs themselves are diodes so you can make a rectifier with just LEDs. Even more, LEDs will also light on AC, they will strobe on half period. Motors can have the simplest designs with AC. DC motors have to use "tricks" to make them work ;)

As an improvement. Angular momentum is a product of mass and radius and some other variables, so you can increase momentum without increasing mass. Second, look into induction generator. Third, what if you also use magnets on both sides to restrict motion?

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!

Some interesting facts: According to the U.S. Department of Energy, the United States had more than 25 gigawatts of electrical energy storage capacity as of March 2018. Of that total, 94 percent was in the form of pumped hydroelectric storage, and most of that pumped hydroelectric capacity was installed in the 1970s. The six percent of other storage capacity is in the form of battery, thermal storage, compressed air, and flywheel. The flywheels store 58 mega watts of that total capacity. Some flywheels use magnetic bearings, operate in a vacuum to reduce drag, and can attain rotational speeds up to 60,000 revolutions per minute.
I A Reid
I A Reid 2 yıl önce
Phobos, storage is not measured in Megawatts, but megawatt hours, i.e the duration that the storgae can provide power for. What the DoE have not included is the amount of flywheel energy in all of the thermal and hydro power plants connected to the grid. These large machines have a very large amount of inertia from the roational speed and large mass of the generators. (Something wind and solar do not have) This flywhel effect has astabilising effect on grid frequency. Incidentally a test to measure how long this rotational inertia would last if power was lost was the reason that the chernobyl accident occurred. That is a problem with storing energy in a flywheel, as soon as you use it to generate power it starts to slow down and power and frequency drops off. It doesn't seem a promising way to store energy for a grid.
Maps 2 yıl önce
@I A Reid right, with each load, you need more force... That applies to about anything related to generating power.

@I A Reid It's output was the same in watts (from thicker and then thinner wire).. so he knows what he's doing but it's all for YT income. We're all done here, we're all done with energy.
@Daniel Daniel If there was functional free energy, not even the massive fossil fuel lobby could hide it. Any country which has access to unlimited free energy would have a massive advantage over any other country, revolutionizing every aspect of technology and industry practically overnight; there's no way that neither the US or USSR would have ignored such a game changer during the cold war.

I’m curious as to what problems arise if the magnets are all oriented the same (all like poles facing outward instead of alternating them). It seems like you could get rid of the rectifier, since it would be a DC output, and just use a voltage regulator if you needed to protect against DC over-voltage. I would think it would have a higher efficiency since you would eliminate the voltage drops from the diodes. What am I missing or unaware of? Nice project BTW! Great stuff!

Idea to make this better is to build a sub part to the axle that's hanging out this section will have a clamp that can grip to the rod at any time that's attached to a high speed gear crank a gear going from any crazy high number to a small one for max speed per revolution and the handle of the crank has a trigger much like a bike has and treat the system like the breaks do but with a clamp to the rod and when you spin the crank for a while let go and the flywheel will keep spinning like it is now and the crank makes it easier to start it up at will and if need be speed it back up this would increase the voltage output due to it spinning much faster and last longer due to more speed stored in the flywheel
Zack Yıl önce
Use a string wrapped around the shaft to get it to spin fast. Also if you want a nice straight shaft you need to get a bigger one than you need of a hard material like tool steel. Then machine grind it to thousands spec. Then machine the flywheel and balance it on a flywheel jig by drilling it. Then fit the shaft in the center with a few thousands spec press fit.

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.

@Elyson Panolino what makes the lines on the road sizzle under the big power lines? After the rain.

As a precision engineer I'd love to make this with perfectly balanced machines parts. Maybe with a geared right up pullstart to get it going mad speeds.

This video simplifies a lot of things….should be shown in basic electrician school. Better than what most teachers/professors try to explain in trade school.

very very cool indeed. the only thing I would suggest to do differently is to change around places for gen and flywheel. you would get less to no wobble.

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

@Ian Lainchbury what about with leather gloves

@Hellfire missile salesman Never wear gloves when using a lathe. The gloves can wrap round the part and pull you in.

@Ian Lainchbury That is a lesson that you do NOT want to learn the hard way, I have seen people getting degloved doing that as well... OUCH!

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.

*Main point he forgot to mention is:* Case 1: If you rotate manually the freewheel which is levitating on the magnet, say, for example, it will rotate for 20 minutes (as there is no mechanical friction) Case 2: If the same rotating free wheel is subjected to rotate between copper coils in order to get electric current, it will rotate for less than 5 minutes Previously in case 1, when no copper coils were connected, the wheel freely rotates for 20 more minutes when subjected to take electric current thru Cu coils, there the free wheel faces resistance, the free wheel should use more of its mechanical energy to overcome the resistance thereby the rotating wheel loses its RPM and eventually stops rotating

You efficiently made a dual rotor axial flux motor, which I suggested to you in your e-bike project before. Just wind a couple more copper wires and stick a VESC to it and see how good it performs in terms of torque. Awesome work & video!

You sure that the design is efficient? I have very much trouble figuring out the orientation of the magnetic fields and how to make their interaction as efficient as possible. Also magnetic field diagrams make me dizzy.
