[00:11] Senku
    With gears and a waterwheel,
    the age of human power is over.
[00:20] Senku
    With an infinite contraption
    that requires no fuel...
[00:26] Senku
    We're finally harnessing
    the power of nature.
[00:34] Senku
    We're overcoming manpower and
    entering the age of energy!
SIGN    Hydroelectric power plant acquired!!
[00:45] Kohaku
    Wh-What is this?
[00:47] Senku
    It's a hydroelectric generator.
[00:49] Kinro
    Hydroelectric?
[00:50] Ginro
    Generator?
[00:52] Gen
    This is insane, Senku-chan.
[00:56] Senku
    Save your praise for Chrome
    and Grandpa Kaseki here.
[01:00] Senku
    They built this huge-ass waterwheel.
[01:04] Senku
    It's not done yet, though.
[01:06] Senku
    All our precious electricity
    is still leaking away.
[01:11] Kohaku
    What does that mean?
[01:13] Senku
    We're building a box to store the electricity.
[01:16] Ginro
    We can store that spinning power?
[01:19] Senku
    Yeah, although it'll be a bit of a pain to build.
[01:23] Senku
    Get off your asses.

[01:26] Senku
    We have a ton of high-difficulty crafting to do
[01:30] Senku
    before we get to our cell phones.
[01:35] Chrome
    Damn...
[01:37] Senku
    It's the start of our Spartan crafts club.
[01:41] Senku
    Damn, this is exhilarating.
SIGN    Spartan Crafts Club
[03:22] Senku
    To make a box for storing electricity,
    a battery, all we need to do
[03:26] Senku
    is dip two sheets of lead in our old
    two-faced goddess friend, sulfuric acid.
[03:34] Gen
    Ryu-san?
[03:36] Gen
    Oh, sulfuric acid.
[03:37] Senku
    Send electricity into this,
    and it'll store power on its own.
[03:42] Senku
    It's simpler than you'd think, huh?
[03:44] Chrome
    It's not simple at all.
[03:45] Chrome
    This is pretty brutal.
[03:46] Senku
    We'll make five more of these
    and connect all of them.
[03:50] Kaseki
    Don't you think the crafts team has
    been working a bit too hard lately?
SIGN    Batteries acquired!!
[04:01] Ginro
    Is it really being stored
    in these tiny containers?
[04:05] Ginro
    All the spinning power from those disk—
[04:08] Kohaku
    It's definitely in there.
SIGN    Battery
[04:15] Ginro
    Does that mean I don't have to do all
    that painful turning with Kinro anymore?!
[04:21] Senku
    Yep. Never again.
[04:24] Senku
    I told you, it's the age of energy.
[04:28] Ginro
    Hooray for energy!
[04:31] Kokuyo
    I'm not surprised about lazy Ginro,
[04:33] Kokuyo
    but even super-diligent Kinro is excited.
[04:36] Suika
    Turning that thing must've been really hard.
[04:39] Senku
    It's not meant to make your lives easier.
[04:41] Senku
    It just means we're using
    your manpower elsewhere.
[04:43] Kohaku
    The fighters can focus on training.
[04:47] Kohaku
    Put your back into it!
[04:51] Kohaku
    We only have a few months until the big battle.
[04:54] Kohaku
    You need to be in shape to
    defeat Tsukasa and Hyoga!
[04:58] Senku
    This isn't the time to be
    taking a break, you two.
[05:01] Chrome
    This is way too Spartan!
[05:03] Suika
    Grandpa Kaseki's going to die!
[05:05] Senku
    There's one more vitally important
    use for the waterwheel.
[05:11] Senku
    It's time for some fun gear-making.
[05:13] Senku
    It'll work magic on the waterwheel's motion.
[05:18] Senku
    Damn it. It broke again.
[05:20] Senku
    Back to copying the designs again.
[05:27] Chrome
    The teeth on just half of the disk
    catch the top and bottom in turn,
[05:33] Chrome
    and that turns a rotational motion
    into a back-and-forth motion.
[05:37] Chrome
    These ideas humanity came
    up with are incredible.
[05:40] Chrome
    This is insane.
[05:42] Kaseki
    The craftsman in me is
    getting way too excited.
[05:45] Kaseki
    It's pissing me off.
[05:47] Kaseki
    Here, leave the intricate work to the pro.
[05:52] Suika
    They were so worn out when
    they saw the diagram,
[05:55] Suika
    and now they're being all tough.
[06:07] Ginro
    I-Is this...
[06:10] Chrome
    It's the air-blowing machine for building fires!
[06:13] Chrome
    Level one!
SIGN    Level 1
[06:15] Chrome
    Level two!
SIGN    Level 2
[06:17] Chrome
    And finally, level three!
SIGN    Level 3
[06:24] Ganen
    This was the hardest work we had
    to do in exchange for ramen.
[06:29] Gen
    The hellish iron-making
    work is finally mechanized!
[06:32] Ganen
    Hooray for energy!
[06:35] Senku
    I told you, this doesn't
    mean you can slack off!
[06:37] Kokuyo
    The non-fighters can focus
    on preparing for the winter.
[06:46] Kokuyo
    Everything I see, I see for the first time.
[06:50] Kokuyo
    This is called bottling, huh?
[06:52] Gen
    It's the ancestor of canning.
[06:55] Ganen
    I can't believe we can preserve meat
    for the winter. I must be in heaven.
[07:00] Gen
    What's the Spartan crafts
    club making this time?
[07:04] Senku
    Light bulbs.
[07:07] Gen
    Sure, that's crazy enough.
[07:10] Gen
    I'm starting to get used to it, though.
[07:13] Senku
    It gets up to about 2,000
    degrees once it's lit.
[07:16] Senku
    That makes the metal connections melt apart.
[07:19] Senku
    We're going to have to use
    glass as a tiny adhesive.
[07:24] Kaseki
    This is so intricate, it's tough even for me.
[07:30] Chrome
    Damn it! This is so hard!
[07:34] Senku
    What's the matter? Giving up already?
[07:37] Kaseki
    Not at all.
[07:38] Kaseki
    Although my body gave up a long time ago.
[07:41] Senku
    I always know I can count on a craftsman.
[07:44] Kaseki
    Sheesh.
[07:45] Kaseki
    I've lived such an easy life
    here for the past sixty years.
[07:50] Kaseki
    But Senku, ever since you showed up,
[07:54] Kaseki
    it's been so much harder,
[07:57] Kaseki
    and so much more fun.
[08:01] Kaseki
    Aside from a few, I bet everyone
    in the village feels the same way.
SIGN    Ramen
[09:42] Chrome
    Wow.
[09:43] Chrome
    Last time we made a light, though,
    it burnt out instantly.
[09:51] Chrome
    What do we do?
[09:52] Senku
    What do you do to make things burn fast?
[09:56] Chrome
    You give it a ton of air
    with a blowing machine.
[09:58] Chrome
    Like we did with the waterwheel, right?
[10:00] Senku
    Then what do you do to
    keep things from burning?
[10:06] Chrome
    You get rid of the air?
[10:12] Senku
    We use the hefty weight of mercury
    to catch the air as it falls,
SIGN    Air
SIGN    Air
[10:19] Senku
    creating a vacuum.
[10:34] Senku
    No matter how hot it gets,
    if there's no air, it won't burn.
[10:40] Senku
    That's how it can last a long
    time without burning out.
[10:53] Kohaku
    Senku, I've brought everyone here.
[10:56] Senku
    Okay, hang on.
[10:59] Senku
    It's almost time.
[11:03] Chrome
    Damn, it's snowing.
[11:05] Chrome
    Are we calling off the test?
[11:06] Senku
    No, I'd like to do it today.
[11:11] Kaseki
    We're all set.
[11:15] Senku
    All right, let's turn it on.
[11:36] Suika
    They're like twinkling stars!
[11:39] Gen
    Decorative lighting.
[11:41] Gen
    I feel like I'm back in the modern world.
[11:45] Kaseki
    It took two months to get here.
[11:48] Kaseki
    That took a while.
[11:49] Senku
    Nah, we're right on schedule, really.
[11:55] Gen
    Hang on, is today Christmas?
[12:00] Senku
    Oh, yeah, now that you mention it...
[12:05] Senku
    What a coincidence.
[12:07] Gen
    Yeah, right.
[12:30] Chrome
    Oh, damn! I have an idea!
[12:32] Chrome
    We can go deep into the caves,
    farther than we could with torches!
SIGN    'sup?
[12:38] Senku
    Right, with batteries and light bulbs,
    we could go ten billion times deeper.
[12:42] Chrome
    I bet there are tons of cool
    rocks deep in the caves!
[12:46] Chrome
    Let's go, science spelunkers!
[12:48] Chrome
    We're going to find some
    awesome mineral resources!
[12:51] Chrome
    Yo, Senku, you may be way
    ahead of me in science,
[12:55] Chrome
    but when it comes to exploring,
    I'm tens of billions of times better than you!
[12:58] Senku
    I'm sure. You've had years at it.
[13:00] Chrome
    What do you want?
[13:02] Chrome
    Captain Chrome will go get it for you!
[13:05] Chrome
    There's gotta be stuff on the cell phone
    road map that we don't have, right?
[13:09] Senku
    Oh, materials we're missing?
[13:13] Senku
    Nothing.
[13:13] Chrome
    There's nothing?!
[13:15] Senku
    We have everything we need.

[13:17] Senku
    Thanks to our hard work in our past missions.
[13:21] Kohaku
    Then is there a reason to go exploring now,
[13:24] Kohaku
    when we're so short on labor?
[13:26] Ginro
    I bet he just wants to go exploring,
    now that he has some new gear.
[13:31] ---
    Gulp!
[13:34] Senku
    Well, it would be nice to have a ton of copper.
[13:37] Senku
    There's no telling how much we're going to
    use during our next brutal crafting session.
[13:41] Chrome
    That's it!
[13:43] Chrome
    I got this!
[13:44] Senku
    Come home soon.
[13:46] Senku
    At least by New Year's next week.
[13:50] Kaseki
    So what's this brutal crafting?
[13:53] Kaseki
    I want to have it done by the time
    Chrome's back so we can surprise him.
[13:58] Senku
    The next-level light bulb.
[14:01] Kaseki
    The light bulb was already brutal.
[14:04] Kaseki
    This sounds exciting.
[14:06] Senku
    We're making computer eggs.
[14:09] Senku
    The gears of electrons...
[14:11] Senku
    Vacuum tubes.
[14:17] Gen
    Vacuum tubes, huh?
[14:20] Gen
    We're getting to the point where
    I have no idea what you're making.
[14:23] Gen
    I mean, I do.
[14:24] Gen
    I know of the name, but if you
    asked me what exactly they do...
[14:30] Senku
    They emit electrons at high temperatures,
[14:33] Senku
    letting us control the direction of
    the current and make it stronger.
[14:37] Senku
    Just think of them as the gears
    of the electricity world.
[14:41] Senku
    It's the heart of a cell phone.
[14:44] Kaseki
    This is tough work, but it's almost
    the same as making a light bulb.
[14:49] Senku
    Yeah.
[14:50] Senku
    But as the name suggests, it's a vacuum tube,
[14:54] Senku
    so we really need to get rid of all the air.
[14:58] Senku
    So we put phosphorus on the
    filament, where it gets hot.
[15:02] Senku
    It'll burn with heat, suck up
    all the air around it, and...
[15:08] Kaseki
    I didn't do anything.
[15:10] Suika
    It cracked at the base.
[15:14] Senku
    The wires are expanding...
[15:18] Senku
    The metal line going through the glass
[15:21] Senku
    expands just a little from the
    heat of burning phosphorus.
[15:24] Senku
    That size difference of just
     a few microns broke the glass.
[15:27] Gen
    Is that the level of intricacy we're dealing with?
[15:30] Gen
    What do we do, then?
[15:35] Kaseki
    Nothing ever works right
    on the first try, does it?
[15:40] Senku
    It's nothing but trial and error.
[15:43] Senku
    When is it ever anything else?
[15:47] Chrome
    I'm back!
[15:51] Chrome
    And I copped some copper!
[15:54] Chrome
    No pun intended.
[15:57] Senku
    This is just the right time for that copper.
[16:06] Gen
    A copper tube?
[16:09] Senku
    A tube will just expand inward without
    cracking the glass around it.
[16:15] Kaseki
    Finally! Man, making that
    vacuum tube was hard work.
[16:26] Chrome
    Damn... The bamboo filament
    burnt out instantly.
[16:43] Senku
    Damn it.
[16:44] Senku
    Bamboo filaments are just fundamentally
    too weak for vacuum tubes.
[16:50] Kohaku
    I don't get the science, but bamboo
    is too weak, is that right?
[16:55] Chrome
    What do we need?
[16:56] Chrome
    If we need something tougher, I'll go find it!
[16:59] Senku
    No...
[17:04] Senku
    There's nothing better in this age.
[17:16] Chrome
    These are all the minerals I
    found lying around in the caves.
[17:20] Chrome
    There must be something in here that's
    strong enough to hold up to the heat.
[17:25] Ruby
    This one's like a gem!
[17:27] Senku
    That's a jewel bug corpse.
[17:30] Ginro
    What about this rock? It's really dark,
[17:33] Ginro
    but light as a feather!
[17:34] Senku
    Raccoon poop.
[17:35] Ginro
    Well, poop!
[17:42] Senku
    I guess we're stuck.
[17:43] Senku
    After we came so far...
[17:53] Suika
    I'm not a rock doctor like Senku,
[17:57] Suika
    but I've seen a lot of rocks while
    playing in the mountains and forests.
[18:02] Suika
    I'm going to find an unusual
    rock that might be helpful
[18:06] Suika
    and be useful to everyone.
[18:24] Senku
    If we can't do cell phones,
    we can't do cell phones.
[18:27] Senku
    I don't have time to be bummed out.
[18:30] Senku
    Think of something else.
[18:33] Gen
    Senku-chan, wakey-wakey!
[18:37] Gen
    It's the new year.
[18:39] Gen
    We should all watch the sunrise together.
[18:44] Gen
    It's important to have a change
    of pace and a fresh mindset.
[18:47] Gen
    That's my line of work, right?
[18:49] Senku
    Mentalists are such a pain.
[18:53] Suika
    I-I'm coming, too!
[18:57] Chrome
    Wait, Suika, were you going
    through rocks all night?
[19:00] Ruri
    You want to be useful too, huh, Suika?
[19:03] Suika
    That's right.
[19:05] Gen
    New Year's, huh?
[19:07] Gen
    Our internal clocks are messed up
    from the petrification, though.
[19:11] Gen
    I don't even know how old I am anymore.
[19:14] Senku
    Think about how many days you've been alive.
[19:18] Kohaku
    Why would we remember that?
[19:22] Gen
    What about you?
[19:24] Senku
    6,268 days.
[19:31] Ruri
    We're almost there.
[19:42] Kokuyo
    The sun's rising.
[20:03] Senku
    It's blue.
[20:06] Senku
    A gemstone...
[20:09] Ruri
    It's pretty.
[20:13] Suika
    Why... is it glowing?
[20:17] Senku
    It's called scheelite.
[20:19] Senku
    It glows blue when exposed
    to ultraviolet light.
[20:24] Senku
    Reactions to ultraviolet
    light are especially visible
[20:27] Senku
    right before the sun rises.
[20:29] Senku
    In other words, only right now.
[20:32] Gen
    A magic stone that glows
    just for this moment...
[20:37] Chrome
    I've never seen anything like it.
[20:40] Senku
    Me neither.
[20:42] Senku
    It's an ultra-rare gem.
[20:45] Senku
    You guys did an incredibly
    good job, Chrome and Suika.
[20:49] Senku
    This stuff is used in modern filaments.
[20:54] Senku
    Atomic number 74...
[20:56] Senku
    Tungsten!
[21:06] Senku
    Heat's got nothing on it.
[21:08] Senku
    It's the strongest metal in the universe!
[21:14] Chrome
    This small chunk won't be enough,
    but it came down the stream in the cave.
[21:18] Chrome
    There must be tons further inside.
[21:21] Chrome
    Tons of this heat-resistant
    treasure called tungsten!
[21:25] Senku
    We only have one set of
    materials left to make a light.
