The magnets need to be in the middle of the radius of the copper disk. Then you get your current from the axis and the rim. The second disk is an idea from Tesla: use different magnet polarity on both disks so that on one the rim becomes positive and on the other negative when rotated in the same direction. Then you use a metallic band (or chain) around the outside of both disks so they rotate together. Then you can get your current from one axis to the axis of the other disk (as both disks are now in series). For more info: check out Tesla's article from Sep 2nd, 1891 "Notes on an Unipolar Dynamo"

The copper discs used in Dr. Stone's generator seem to be a couple of metres in diameter, at least bigger the height of the characters. Judging from the way the copper was beaten flat and how rigid it seemed, probably at least 2mm (to maybe 4mm) in thickness. That would have made an exact replica a bit pricey to construct, just from the cost of copper sheet used.

Also the fact that he placed the magnets wrong, senku placed the magnets as per teslas design, meaning instead of just positive or negative charge, it can generate both at the same time depending on wether the disks are spinning in the same direction or opposite directions, this would be significant enough to change the output, including the size of the magnets, the size of the sheets and the slight change in design, i would argue senku's version could output anywhere from 1 to 2 bolts, and thats without taking into account the speed at which the copper plates were spinning, its also woth noting senku's copper plates are thicker and are more grounded, the axis they rotate on being more fixated helps in the rotation, its also why senku needed 2 people who were very strong and could work in synchrony, he wasn't going for too much efficiency with that first design, that was just part of his sadistic nature given he could have introduced gears in the first place because he already had shown a pulley earlier in the show

I think the thinness of the copper is definitely part of it. Even in the Dr. Stone clips, you can see that the copper discs are about 3/8" thick- and the hammering process means that they're work hardened, and probably a lot more even and flat than yours. As with a lot of what you make, the difference is, I think, in the precision of the construction. Wobbling stuff is less efficient stuff. Of course, the best sort of generator would be a cylinder style, if you have the magnets.

I believe the generator does actually have a couple of "practical" albeit uncommon applications. They are used for high amperage discharges, I think the US navy's railgun was supposed to use on of these, because the ship's power plant didn't have the instantaneous power output capacity. You can store a lot of kinetic energy in the rotor, then quickly discharge it all at once as a high current (but low voltage, as you saw) pulse.

An electrical potential is created by change in the magnetic field. If you have a load of magnets all with the polarity in the same orientation (I'm guessing you've done so, because of the steel plates you've put on top) it's not going to work properly. If the magnets are alternating you should get much better results. I'm quite curious on how much power you would get from it 😁

With a homo-polar generator you are exploiting the Faradays law -> Voltage =Length*speed*Magnetic strength. The mental model I use for this is imagining the disk as a bunch of individual wires. When moving a wire through a magnetic field you get charge separation at the ends. In principle this means that if you dragged a very long straight strip through a magnetic field you could get a current if you tapped the sides but spinning it is easier. Suggestions for improvement: 1) Very strong magnets on both sides placed along the radius of the generator all the way from edge to middle. Placing the magnets on the edge won't help because unless you have a pickup all around the outside edge the electrons have to fight the other currents to reach the pickup which only touches in one place. Also the placement along the radius lets you maximize the length of the copper passing through the field. 2) Thicker disk, 1/4 inch or so. This should make the turning more stable and make for a better connection at the edge. Also the momentum should help as the generator gets moving. 3) Use graphite to lubricate brushes, as a conductor a thin film of graphite could help with better brush connectivity if things are a bit wobbly 4) speed, the faster the movement the greater the force for charge separation. Two ways to get speed, bigger circle or some kind of gearing on the crank. p.s. adding the plate steel effectively killed your magnetic field as there is a significant shielding effect from steel. While it probably did even out the field it also made it weaker.

the amount of copper atoms passing through the magnetic field will also increase the Magnetic strength variable in your formula. So a thicker disk has more dense magnetic field. Also, the hammer marks made in the Anime version create more surface area and areas of change as they pass through the magnet. This could also significantly increase the power generated.

Isn't the issue that you're not collapsing a magnetic field in the presence of a copper coil? You're just keeping the coil exposed to a constant magnetic field. Didn't you make that worse by creating a homogenous field with the plates? This is why generators have to be run through a bridge rectifier no? I'm no expert btw, this is just my understanding. :)

If the magnets are alternating polarity, then it's not a homogenous field; Andy didn't say one way or the other, so we don't know whether or not he did that. As I understand it, alternating the structure of the copper itself can also help, so counterintuitively, punching holes along the path of the magnets could also help. Since Andy was just trying this out before moving on to more effective methods, though, I imagine he's just going to go with copper wire coils, which simultaneously gives the structural variety and a larger volume and surface area passing through the magnetic field. Edit: brain fart, accidentally wrote batteries instead of magnets

In the rotating copper disc the Lorenz-force is letting the electrons spiral inwards towards the axle and as such creating a a negative voltage at the axle and a positive at the outer rim. The rotation velocity, the strength of the magnetic field, the homogenity of the field, the resistance of the metal (kind of metal and thickness and temperature), the surface contact etc. are playing a role in creating the voltage.

Ignoring the electrical connections to the rotating disc and the magnet polarity issues for a moment; He also literally shielded the copper from the magnetic field with the "upgraded" version, while simultaneously creating such an astoundingly inefficient magnetic circuit (by forcing the magnetic fields to close through the air), that even the immense B-fields and volumetric energy products of modern Neodymium magnets was choked down to almost nothing! If he just replaced the wood supports used in the small-scale versions (showed around 13:50 and 13:56) with iron or even mild steel, it would probably have worked, though a larger copper disc would also help. Well, that is as long as he kept the thickness the same as the wood (or going even thicker) and doesn't just slap a 5mm steel sheet on and call it good.

@@alexwang982 changing magnetic field is necessary for AC but homopolar generator generates DC, so the magnetic field doesn't have to change.

Just FYI, hammering the copper sheet stiffens it via work hardening. The same is done to the edge of bronze swords to help them stay sharp. Also, stacking multiple layers of copper and magnets would allow you to stack voltages in kind. Just attach all of the copper layers to the same shaft and be precise about your spacing. For better brushes, try using copper sponges (used for cleaning copper kitchenware) or carbon based materials. While graphite has excellent conductivity, the lamp black carbon that remains on burnt wood can be fairly conductive if there is enough of it present. Adhering a wire to this surface could give a very crude form of brushed contact. But, this may not last long if the copper sheet rubs through the layer of carbon. To make the lead into sheets, you can use two pieces of wood as rollers and make a basic rolling press. Lead is soft enough and it can be annealed at relatively low temperatures if it gets work hardened. For the rollers, bigger is better. Let the weight of the wood do the work for you. Two 12" diameter rounded slabs that have been properly oiled should give a decent mass per length. Use rollers that are much wider than the sheet you want to produce to increase the pressure in proportion.

A very crude commutator bar with roughly made graphite brushes will work very well. Dried shellac still has some give and also decent insulating properties.

Hell, the fact you made batteries that can take a charge is pretty impressive. I do agree with you I think you made your sheets too thin; going back and looking at the original clip, they grind the edges with corrundum (and likely the sides too, all for the sake of polishing I assume) which tells me it can't be a thin sheet of metal they're working with, probably something like a quarter-inch or centimeter thick piece of copper they've got there. Assuming how intelligent Senku is supposed to be, I also assume he devised a bearing system to hold everything much more stable, which you'd pointed out was a possible problem. Lastly, I'm by no means an electrical engineer but it looks like as presented (and shown several times) they've wired both disks together in some manner (I assume in series since there's only three cables) and the middle one crosses over in some fashion obscuring where it attaches but likely the two cables coming off the disks are on the outside and the connectors on the inside for... some reason. You're very obviously on the path to something, and if you had to make this in a world with nothing you'd be looked at like a magician after all. Can you try cooking a bamboo filament next?

Creating a DC generator without magnets can be challenging, but you can use a design that involves a coil, a rotating armature, and a commutator to generate direct current (DC) or pulsed DC. Here's a simplified design: 1. Coil: Wind a coil of insulated wire (copper) around a cylindrical form to create a solenoid. This coil will be the primary component for generating electricity. 2. Armature: Inside the coil, place a cylindrical armature made of a conductive material such as copper or iron. This armature should be free to rotate within the coil. 3. Commutator: Attach a split-ring commutator to the armature. The commutator consists of two separate segments that are insulated from each other. Brushes (typically made of graphite) will press against the commutator segments. 4. Brushes: Position two brushes in contact with the commutator segments. The brushes will conduct the generated current to an external circuit. 5. Mechanical Energy Source: You'll need a mechanical energy source to rotate the armature. This can be achieved through a hand-crank, a small turbine, or another method. 6. Induction and Commutation: As the armature rotates within the coil due to the mechanical energy input, it induces a changing magnetic field within the coil. The brushes press against the commutator segments, and as the commutator rotates, it switches the direction of the current in the coil, effectively converting the induced alternating current (AC) to direct current (DC) or pulsed DC. This design emulates the action of a commutator in a DC motor, ensuring that the output is DC or pulsed DC. However, the voltage and power output will depend on the design and size of the generator, and you may need to fine-tune the design to meet specific requirements.

A big problem I see with this type of generator used to charge a battery is that when not being spun (or spun too slow), the battery will just discharge right back into the metal disk since the terminals are effectively a dead short through the contacts and the copper disk. Remember that to charge a battery the voltage source has to be higher than the voltage of the battery for current to flow in the right direction and charge the battery. A way to prevent this is to use a series diode, but that has it's own losses (and a forward voltage drop) so you need the generator voltage to be a bit higher still to ensure the batteries charge and not discharge or do nothing.

A couple things could possibly help with the generator and battery. 1. More rigid copper rotors, preferably work hardened, should give more consistent area passing through the magnetic field. 2. A 2nd magnet with reverse pole on the opposite side of the rotors. We know senku had 2 magnets at his disposal so why not. 3. I know its incredibly dangerous, but its worth mentioning, the acid they used actually exists. The lake itself is known as lake yugama. The water there is the strongest acid water in the world with a PH of 1.0. A stronger acid would provide more of a potential charge. 3. Keep in mind, senku did this on a much, much bigger scale so the voltage produced is gonna be alot less in comparrison. If i had to guess forthe batteries themselves , they appear to be in at least 1-3 gallon containers. All in all what were seeing here, is that Dr.Stone knocked it out of the park 10 billion percent with the science behind every invention, this is just the small scale that backs it up.

Stone age method to precisely measure volts and amps: Galvanometers are fairly easy to build, and so is an expansion voltmeter. You can use a known resistive value substance (i.e. 50% saline solution of a given volume) for calibration. Homopolar Generator:These are primarily high current generators, but the voltage can get up to 500v for a big machine. The design from the show reflects an improvement from one of Nicola Tesla's patents. Having a direct conduction between the centers or the periphery allows you to take voltage from the non shorted sides. For your example, it would have been better to use thicker copper disks and let them scrape against each other or against the magnet (or electrical contacts attached to the magnet). The orientation of your magnets is an issue, since one pole being closer to the center is the key. They used to be called N-pole machines, because the common standard was to put the north pole close to the centers. Back when they were cool, some companies were even making ring magnets that had the north at the center. Naturally the faster they turn, the more electricity you'll get out of them, so using a pulley system would help.

You’re actually really close to creating a Bedini SG generator! You should definitely take a look at that here on YT! The wheel design with the magnets that you came up with is very similar to how the Bedini SG generates electricity. It instead uses a coil consisting of two insulated wires charged to differing polarities that are twisted around one another, wrapped around the coil, and placed at the base of the wheel contraption right below the free-hanging wheel. This would create an electromagnetic attraction towards the magnets and the coil when given power. The wheel would then be spun and when a magnet on the wheel passes over the coil, they first attract each other, and with the momentum of the wheel and continued attraction of the following magnets, it is swept past the coil creating a brief influx of electricity sent through the wires in the coil that can be harnessed into a separate battery. This does require the use of other components so it’s not the simplest layout; regardless it is pretty simple and definitely worth looking into, and you may even be able to draw inspiration from this design! Wishing you the best!

A homopolar generator is a current device. I do not know why they choose that configuration in that animation; they may have had concerns about making a device that a child could replicate and cause injury to themselves. If you are doing the rebuild society route. You might first want to start with primary cells before going to secondary cells. If you have any metal and activated charcoal you can make mechanically recharged cells. For example iron reacting with oxygen would make "rust" and that rust could later be refined into iron again using available materials found all over the planet. I did want to mention counter rotation can be an effective means of extracting useful power. I suspect that device in the animation is purposely "failed" to keep a child from injury. There are many other "ancient" electricity generators that can make exceptional voltage. For example a Wimshurst generator. Again, its a show that young ones will likely watch; the more I think of it is a purposeful fail.

Or it might have been an experiment conducted by the author when they were younger. We should contact the author and find out what they were thinking? Anyway, if you can generate 3 or 4 volts and 10 amps of current using a homo-polar in series. That would be more than enough to charge a lead cell.

For the copper disk generator. The magnets should be pulling on each other instead of pushing. Pushing would mean the change in field lines are parallel to the disk. Pulling would make the magnet field perpendicular to the disk which by the right hand rule would push electrons inward or outward. Also putting the drag wires near the magnet and on both sides would be better since in no magnetic field, the electrons would flow back to equalize any voltage potential.

You can actually use a lead acid battery to generate sulfuric acid. Simply add distilled water and Epsom salt, also known as magnesium sulfate to an uncharged, also known as discharged battery. Charge the battery and it will create sulfated lead, which will leave the Magnesium behind. Remove the excess sediment, and add distilled water. Discharging the battery will then generate sulfuric acid. Also, when first charging a battery using pure lead, it is not the same as a normal charge cycle. It takes much longer, because you must convert the lead into sulfated lead. It is unclear exactly how long, it is more than 1 week, possibly months. The battery manufacturers keep it secret. Also, you must consider the depth of charge based on the thickness of your plates, because if you convert all the lead, it will become very fragile and crumble.

Based on the concepts in magnetic braking, I think you basically need the conductor to be moving in and out of the magnetic fields. Having the relatively solid loop of magnets won't help, unless you reverse every other one. But then, in order to capture the voltage differential, I think you'd need one pickup within the field, and one outside the field. A coil of wire, moving through a horseshoe magnet will generate power according to the right hand rule while moving into the field, but then the left hand rule while moving out of the field. Interestingly, while the coil is right in the middle (it was a huge horseshoe magnet that we used) it generates no current. So moving into and out of the field is where the current is generated.

Fire would still he the go to for light untul you got enough batteries to cycle through and charge up while the lights are on. Hell, in Dr. Stone the intended use for Electricity was communication. The lights were just to show off how powerful electricity is and to boost moral. So regarldess of how weak it is, the fact that it generates any electricity at all, and the fact that the baterries work and be recharged, means that the whole thing douse work. It works incredibly inefficiently, but it works. And qgen you are just stepping into new technology, "it works" is all you are looking for.

I think the generator you used is a good proof of concept, but the fact that you have to use contacts that aren't attached and potentially not conducting all the time is the biggest downfall. If you use the same setup but just spin the magnets you might see better results because you can guarantee the contacts on the copper. Also I might be wrong about this but it may be worth looking into: current is generated by magnetic fields moving through the copper, so if I interpret that correctly then more magnetic fields means more current. I think the plates you added to the magnet wheel made all those fields into one that is in the same direction of the movement therefore limiting your current. If you're actually reading this hello!
