About the gold, they have a material collector (Chrome) that collects random minerals

As a mech engineer, this episode was seriously hype for me knowing the technological advancement they just achieved

I believe the gold ore is actually in high quantity available to them for an amazingly cool reason that I definitely think the author considered when writing the show. You see, Japan in the modern age has very very poor ore quality, which may make it seem very stupid that they have so many resources available to them that are seemingly of pretty good quality, given how clear their minerals look. But you have to consider that Japan is in fact located right above a converging tectonic plate boundary (think about how many earthquakes and tsunami's Japan gets, or how even the word tsunami is Japanese), now think about how Japan is an island and how islands get formed; by tectonic shifts and collisions. Now this is where it REALLY gets interesting: Researchers have discovered that while on Japan's surface the ore quality is poor, the sea bed is a whole new story, the bottom of the sea riiiight next to Japan is enriched in ores and minerals of very high quality. This has even led to the development of underwater mining machines and facilities, though they're not quite there yet. Now we know Senku and his buddies are on the coast (which btw has huge walls surrounding it, meaning the sea floor has risen!). Hurray! Minerals for days! But it gets more interesting, and this makes me absolutely certain the author knew about this. When we look at a map of the land that is Japan in the furure, we see that Senku's camp is right on the area of most tectonic stress! TL;DR: Senku hit a literal gold mine. Now I don't feel comfortable sharing any links here as they might auto-delete my comment so I'll just say that if you search for the words "Niigata-Kobe Tectonic Zone", "Dr. Stone map Japan" and search a bit on wikipedia about Japan's ore deposits and mines then you'll get there for sure.

I love that senku is like "I'm not using none of that coper crap, I'm using gold for my cable"

The next episodes can make you 10 billion percent hype. More Dr. Stone~!

Still couldn't find "Real Assassin reacts to Assassin Creed" video.

this is so exhilarating

The water wheel idea came from chrome when he saw the gears and saw how it stays in the same speed and spins forever. Then he told the old man his idea and they made a water wheel that they were going to use for cotton candy.

I wanna go to sleep but I also wanna watch this.

Me as a student of electrical engineering loved the show

He get all this gold because Chrome non-stop find every materials he collect in his cave he explore for years...he just get lucky

I like this show bc it makes you appreaciate all the inventions we take for granted. And I like how Senku is superhumanly smart but he's not a mary sue. And this episode with the waterwheel shows that Crome is also incredebly smart. He only lacks the knowledge Senku has. Sry if this sounds weird I'm not good with words.

To be fair, the old man and Chrome didn't come up with an idea for hydroelectric energy, they only came up with an idea to harness the _kinetic_ energy of the river, just like the original invention of the water wheel. Senku was the one who knew of a better way to use it. It was still an amazing intuitive leap for them though, mind you.

This is where the fun begins.

The cell tower explanation was the first time I’ve been confused throughout the whole series

As a former EE student now turned Physics teacher this really takes me back to my days as a communications specialist. i love this series

Whenever i see your wow reactions to senku's ability to make something, i always felt really proud of Senku and DrStone anime in general!

Fun fact, dialing 9-1-1 will ignore everything of other carriers so you can make the call, in other words if you have say, T-mobile, but you don’t have any signal, and there’s a Verizon tower nearby, if you dial 9-1-1 your call will go through the Verizon tower because it’s an emergency line

I recently stumbled on your channel thanks to Dr. Stone. It is really great to have someone with a bit of knowledge confirm these concepts that seemed right to me, but what do I know :-D

Your comments are so unique and precise. Thank you for another extacy for this show has to offer.

Gold is a metal that stands the test of time. If there was a bank vault with lots of gold in it, the bank would crumble away but the gold would remain under a fairly thin layer or rock and dirt. Or be washed away by weather over time.

100 percent, that's how you smelt wire. It's really easy with gold and copper due to their low melting point and malleability, under both hot and cold conditions. You use the momentum of the bowl to create basically a whirlpool, wich will naturally bleed out the wire. The molten metal should cool as it gets forced through the hole into the open air.

Im studying Mechatronics and i can clarify that gold threads are able to be maked like that because steel melt after 3000 celsius and gold melts after 1000 celsius approximatly. The problem ist the cooling though

10,000,000,000% entertaining

Its almost like spin casting or centrifugal casting but instead of a holding vessel its extruded out of the small holes. Usually wire is made through a reductive process of rolling mills, consecutively squeezing the rod stock more and more, thinning and lengthening it into wire. Insulation is done by essentially pulling the wire through liquid plastic/rubber baths or cascades. You can do a similar process at home with bare wire and plastidip(the kind for rubberizing tools) The way its presented in the show is actually pretty clever. I don't think it would work without having the casted wire secured onto feed rolls to pull it through, preventing it from bunching up. It'd be neat to see someone try to recreate some of the things in the show.

as always, awesome review! you're gonna love the upcoming episode, most especially the last one, more dr stone please!

If there's three cell towers near you, and you try to make a phone call...*ads comes in"*.. Me: oh, looks, interference

late comment, but I absolutely loved this episode! we are so fortunate to have easy access to everything so when i watched dr stone i was in complete awe since the sense of achievement from scientific advancements was so refreshing! Watching your reaction reminded me of when i first watched dr stone!! It definitely became my favourite anime (for the past few months it's been so difficult to find other anime because i enjoyed dr.stone way too much😅) the bond between senku and his dad, and senku with his friends is also very touching.

That is the filing of this show see what we take as granted and think about how to make from zero, and you have to keep up the show the last two episodes is just magnificent

2bh with our current knowledge, making a water wheel for perpetual motion energy would be one of the first things you would build, it doesn't need a huge amount of tech and will help with almost all other developments. It was something I was kinda anoyed by when watching the show especially how 'smart' Senku is. He builds extremely elaborate machines but not something relatively simpel like this thats been used since the Roman times. Brw love the reactions, this year season 2

Engineer-sensei gives heart for early people?

this guy is gonna get addicted to anime

8:16 be like CHIDORI

Love this!

The most conductive metal is actually silver, but silver is highly reactive. Gold is actually a worse conductor than coper, it's just extremely inert so it doesn't corrode.

I love this series

Please do more episodes !!!! nice job

As an engineer you know there is no Centrifugal force. Bro.

“Everyone be talking about how chrome got the gold” **Should’ve Mined in the nether**

i like how honest you are

MOREEEE DR STONE

This is just a guess on my part but one reason for them having so much gold is due to it being left behind by the old world. Yes natural sources of gold are hard to come by, but the old civilization already mined and extracted lots of it and then left it lying around when they turned to stone. Combine that with humans tendency to want to collect shiny things and it isn't surprising that they have collected a supply of it.

# more DR STONE

This episode was badass

Way to tell us how to avoid the FBI's triangulation algorithm lmao

Rather than saying how much the thing cost its how rare the thing is, that is the worth to the world right now.

the titel says "real" engineer. the first thing i hear in this video is "...im an electrical engineer". this is why i have trust issues.

The genius was stumped by cotton candy

More doctor stone, watch all eps to be amaze

more dr stone ep by the way like your videos

@5:10 "I don't know how they make that wire". Haha this seems cute. Though even me, an IT can't really explain or understand how does the basics from basics of my course works. Watch these with Discovery Channel and you'll get brainy :)

This makes more sense than a doctor watching it

3:49 That's why I never turned on my phone's location if not in use.

8:10 that is really awesome 👏👏

I'm over tripping thinking that the video wont play

More dr stone

the village is sitting on the remains of tokyo japan. gold never decays. therefore all the gold in tokyo is sitting just a few feet under the ground. the same can be said for iron. anywhere there used to be a skyscraper, there should be a massive vein of high quality iron ore.

can't wait for season 2 to drop

more please

I get the impression that for the Gold it is just that they DEPICT the gold wire to be fairly big (rather than the "Smaller than a length of hair" it would be) to make it easier to animate. . So it just looks like a LOT more gold than it actually is. . Think a spider and its web. A small spider can produce several kilometers of silk in a single go (Some as much as 1000km for a single web in a single day... which funny enough would be enough to go to the mountain and back)... . Edit: I also did the math... Cotton candy strands are so tiny that 30 grams of sugar can create 4km of cotton candy. So, it isn't THAT much gold (at least not the treasure chest full of gold coins you are thinking).

me listening to his cellphone tracking explanation and thinking that he went police in secret before being engineer watching this 2nd time after dr. stone stone wars ended thanks for highly knowledgeable content .

The cotton Candy machine is actually similar to a techique that can be used to produce fibers... we used it in lab to produce polymeric fibers so i guess it could be the best way he could get it

He is more creating a radio transmitter that is more akin to the radio that truckers use instead of the shorter frequency band often used for cellphones. AKA long-range radio communication system.

I like the background

6:40 plus, you know that whole "diamond cartel" thing, which is why diamonds are so expensive? (basically, the same people who sell you the Jewelry will tend to own the mines and such) Yea, applies to gold too somewhat.

I would like to point out, that the villagers do seem to have dogs, so they have actually domesticated animals, just not multiple species, or on a very wide scale.

The gold could be from a gold reserve that was around before stone wave.

2:00 there's still gonna be environmental noise though. And all the effects of transmitting are gonna be things you have to work around. Reflection, refraction, absorption

Sorry, you missed a couple things here. The wheel senku already invented. Used it in his pulley system then immediately after made a wagon thing. Also the village has pet dog (Ramen episode) But yeah this is cool

By the way an interesting touch in the manga that correlates to this episode, in chapter 52, when he says the time limit is spring to make a cell phone, the imaged he is holding, the phone screen is cracked, just like every phone I have ever owned. 🤣

I WANT MORE THIS ANIME IS AWESOME.

8:15 soundtrack actually chilling

Imagine his reaction when senku said they are gonna make rocket 😂😂

Remember the soda waterwheel? I think they study from it.

Didn’t they mention gold at first and then decided it would take too many resources and made it out of copper instead?

I always wonderd why senku did not create hydrogen with the electricity.

It only ramps up from here

Its like bloodline stronger than their "learning ability"

I got into science because of bill nye and senku

Try this tongue thing now, Senku!

The wheel was introduced in the beginning bro.

Perry if you are the first one to break free of petrification

as a 9 year old I understood 87% of what he said AREN'T YOU EXITED FOR SEASON 2

They have no concept of currency Ryusui go brrrt

"There's no other technology on earth" :0

Imagine if somebody dams up the river...

the gold probably comes from the river or they found a medium-sized gold vein in the mountain, Japan is a volcanic island so its not outlandish for them to find that much gold as an untapped resource

The one thing I dont get about this anime is how people descending from astronauts got to think that soap bubbles are sorcery

title could be technology explained in Dr. Stone

man doesn't know what a cotton candy machine is bruh

Chrome might have been collecting from a gold bank or jewelry thats been degraded into a cave over 3000 years lol

Why did the writers choose gold. Copper is proven to be super common for them

3:57 that is from a cotton candy machine

Don't get too attached to any machines... They all usually get recycled

of course we know what hydro pump is... it's a water pokemon attack.

I wanna see a mechanical engineer reacting to the same thing 🥺

i wish there is no other anti scientist guy and we can watch more crafting consept episode

They don't do cell phones it's land lines

So good at 1 billion persent omg

Can we reach higher grounds if we cut the idea of cost of resources? Gold in the stone world?
