do both wheels spin the same direction? how many amps/watts does it make? how efficient is it for energy in/energy out? could you put a belt or something so you only have to put the drill on one of them? can u hook an led or something to it? maybe charge a phone?

amazing

Don't know anything about amps and that, what can you power with that?

Una pregunta cuanta energía gastan los taladros

How to build it

Nah he was only warning you about gunpowder

either way you can not do much with 7mA not even turn on an led

@@danthepapertowelman9255 I think they warned about the copper discs being sharp but that's all lol

@@mentalinlaw1265 Kids *shouldn't* have access to power tools unsupervised, and that's an important distinction.

They not warning them because the thing in the show will work in real life, they warning because they afraid kid will try to replicate that with real tools that might cause serious injuries to them if it go under unsupervised. Kid don't have access to power tools and no one will sell them or they even have the money to buy it. But their parent does, and who can say that they can have a vision on their kids 24/7? If you says that you're not a real parent, don't say like you could when you aren't even one. I do have access to power tool when i was a kid, although i don't have the permission to because i'm a smartass kid and it a blessing that i know what i'm doing and don't end up being crippled.

You're about 9 billion percent off

@@jengaman7688 woah didn't noticed that

@@sahiljadhav3553 one of the examples is you cant make a magnet by just 1 lightning you need 10000 lightning

The lightning magnet is absolutely legit. Former Nasa researcher turned rocks into magnets using that same method

@@onionguy1 lol no! do u know how much electricity does a bolt lightning produces? It produces about 300 million volts about 30,000 Amps, Dr. Stone is absolutely right on the magnet scene in comparison, a typical household current is about 120 volts 15 in Amps

I love that your pp matches with your comment

no homo polar

It'd be a waste of time considering the sheer amounts they got wrong, how much of it is flat out impossible and generally wouldn't actually work.

@@Coecoo “they” being Dr. Stone or Mythbusters?

@@connorgrynol9021 Dr Stone mostly but mythbusters fuck up a lot as well

@@Coecoo I would disagree. There are no mistakes in the pursuit of science. They presented a hypothesis, performed experiments, and drew a conclusion from said experiment. Just because it wasn’t the conclusion someone else got doesn’t mean it was wrong. I will say, however, that the whole Busted, Confirmed, and Plausible things were a bit much. It was more like, “from what we learned from our experiments ______ does/doesn’t seem possible.” But the whole Busted/Confirmed thing was certainly more marketable.

@@connorgrynol9021 I never said they were wrong in pursuing science. I pointed out that they have a history of failure when it comes to creating things to test any given hypothesis, misunderstanding conditions of certain myths (like the tooth filling one) and even drawing the wrong conclusions on some shit.

P.S., it also looks fantastic

Ikr

He used neodymium magnet that’s why

Um..... Waht 😕 Is there a part two where the hamster wheels are attached🤔did I miss the video where he replaced the discs with fidget-spinners... 🦊🚬~ur welcome..i left a dislike for my troubles . .

@@intermodus2180 what hamster wheels? whats fidget spinners? tf you talking about

There is no stronger permanent magnet than neodymium. The generator's bearings has much larger frictions than modern ball bearings. So the efficiency would be totally shit just like we've seen from the video where he used 18v nominal electricity to generate around 7v and this is with modern bearings and neodymium magnets, but it gets the job done.

I'm gonna throw this out. At the larger scale, the wheel diameter makes the speed of the circumference of the wheel much larger as Pi*Raduis*RPM. Since the voltage is actually dependent on the speed of the disk under the magnet, could not a larger wheel with slower RPM generate the same (or higher) voltage?

@@kaikart123 Actually there is competition with Neodymium in the form of Iron Nitride & Samarium Cobalt. There are more recent research papers that suggests these materials are both more available & create magnets with higher energy density than Neodymium. Samarium Cobalt even has a much higher temperature range of usability. Also this isn't the best generator design and you will always get out less energy than you put in given the law of entropy.

@@kaikart123 dont need to worry about efficiency when you got meat powered generators!

@@seanshomeshop325 yea, as long as it got the job done with the things you have, efficiency is not the priority.

It was already half of the episode, besides they had the master craftsman do it, senku was hopeless at it

@@codebracker that's true but not the point of was making, the KZfaq channel how to make everything showed how difficult it is to make glass from raw (emphasis on the raw part) materials even with knowledge of the process, also sure he's a master craftsman but that was mostly wood carving and stuff, glass is way different and nothing like anything he'd seen before because it's such an advanced technique

@@jobdunnright1932 true, dr stone mostly handwaves this with the main cast being the apotheosis of whatever their craft it

I loved the show til they made a vehicle in like one episode … felt like the further in the season I got the more rushed to story was I loved learning and seeing him take his time not just … Screen transition… here we are new car

Hey this should be Dr. Xeno catchphrase.

@@bhirawamaylana466 your right

haha manga reader! science is truly elegant

@@pratikkarale8541 10 Billion points for your amazing answer.

I mean, not all of it. There are some really dumb things, like casting iron (iirc?) in wooden forms.

@@VieneLea I mean it's not the best way to do it. But in a situation like that you do what you can

they test it first they showed it

There are very-very many dumb things in the show, and only the working examples are tried, that were taken from books to begin with. Some things you should definitely not try.

@@VieneLea didn't he do lost wax casting tho? Thats a real thing. and you do use a wooden box for that edit: yeah my bad he does cast in wood which is kinda stupid

and they needed a DC current source.

No they did have copper wires, otherwise they would not be able to have the light bulb above chromes hut while the generator is below.

@@pandarojodronero2919 monopolar generators generate DC on their own that’s why they chose this one for the show

It would be the same. Hooking it up to a river or stream is just so it can run automatically, any time, and you don’t need to sore your muscles just to run a simple lightbulb now. So it’s basically tricking nature to harvest “infinite, automatic power”, but not “extremely fast power” (It’s infinite power with no problems if the mini hydroelectric plant is used for a small village, to build thousands of these plants to support an entire country like America is a different story.

@@potatoboy549 The output would actually vary depending on the rivers flow rate and gear ratios used when hooking it up, but overall the main benefits are as you stated.

Homopolar generators, like more, need to run fast. With the right gearing you could do it, but without precision engineering you'd be replacing a lot of bearings.

A diod at best would light up from 7V

nobody likes click baited title cards, why would you want them ?

I come here thumbnail not very interested but the title make me click this video and see again thumbnail make me remember I already see in anime. I want see someone real life build something similar with Dr stone.

@@Kirusion Because they work.

Right now, I'd be more interested in the adoption ( and possible continuation ) of the short *Reboot: Byakuya* spinoff Series... I mean... Considering where the mainline story is going ( up ) they kind of have to merge ( already there ) with each other 🤔

@@Duraltia hmmmm I'm not sure what you mean... But If you mean the side comic of senkus father in the space... I think they already put it in the anime So I kinda skipped it... Should I read it? I red the Manga while ago

Somebody had continues the legacy of the Mythbusters

@@stanleyronblake1646 agreed.

I'll be posting an update video with more information soon :)

@@Sammzor and he never did. The end.

@@openlink9958 Would you watch one if there was one? This is a homo-polar generator, unique in that it generates DC current directly. If you spin the wheel fast and then short the wire, the thing will discharge a huge amount of current. Heres one with a 4 meter disk that weighed several tons which they used to conduct experiments. kzfaq.info/get/bejne/r82aoMWpmbixh3k.html

@@MediumPointBallPoint nice

Try it urself, watch the anime again or read a book I mean YOU cant be that lazy dude....

That would demagnetize the magnet fairly quickly. Great if you've got a large amount of magnets lying around, not so great if you dont

It's a step-down transformer!

*0.007, it's a multimeter with millivolts :)

i've thought about it, if i can get it to be more stable when it spins i'll try to make one

hahahhaha

Larger disks means you don’t have to turn them as fast to get the same output. But it’s way harder
