Sorry, hon.

對不起，親愛的。

In simple terms, every atom has a nucleus

簡單地說，每個原子都有一個原子核

that contains positively charged protons and neutral neutrons

含有帶正電的質子和中性的中子。

which are surrounded by negatively charged electrons.

被帶負電的電子所包圍。

These electrons "orbit" the protons and neutrons

And there's a lot more complexity to this,

而且這裡面還有很多複雜的東西。

but we're gonna keep it quite simple for now

但我們現在要保持它的簡單性

and not try to enter the quantum realm.

而不是試圖進入量子領域。

Now electrons, in particular the outer electrons,

現在，電子，特別是外層電子。

can move between atoms.

可以在原子之間移動。

Generally that movement is in all directions,

一般來說，這種運動是在各個方向。

but if we can make them move collectively in one direction,

但如果我們能使它們集體向一個方向移動。

that becomes an electric current.

變成電流。

What's, like, the hottest way to hold a shovel?

什麼是，比如說，最熱的拿鏟子方式？

Like, over your back?

比如，在你的背上？

So we're on our way to get some anaerobic bacteria.

是以，我們正在獲取一些厭氧菌的路上。

Mitch: In some mud!

米奇。在一些泥漿裡！

Greg: We're looking for Geobacter bacteria

Greg: 我們正在尋找Geobacter細菌

as well Shewanella bacteria.

以及Shewanella細菌。

Basically, anaerobic bacteria exists in environments

基本上，厭氧菌存在於環境中

where there is no oxygen,

so not only do we have water covering this here,

是以，我們不僅有水覆蓋在這裡。

we're gonna dig down under the stream, pull up a bunch of that mud,

我們要在溪流下面挖，把那些泥巴拉上來。

and hopefully we'll be finding anaerobic bacteria.

並希望我們能找到厭氧菌。

- Imagine we found, like... - A terrifying animal?

But the absence of oxygen,

但是沒有氧氣。

some special anaerobic bacteria

For our bike experiment, we have built this rig here

對於我們的自行車實驗，我們已經在這裡建立了這個裝置

to hold onto the back wheel,

and we have it connected down here to a little skateboard wheel,

我們把它連接到下面的一個小滑板輪上。

and that skateboard wheel is actually spinning our generator.

而那個滑板輪實際上是在旋轉我們的發電機。

Generators use magnetic fields to move electrons through metals such as copper.

發電機利用磁場使電子在金屬（如銅）中移動。

This principle is tied to Faraday's law of induction,

這一原則與法拉第的感應定律相關聯。

which states that when you move or change a magnetic field

其中指出，當你移動或改變一個磁場時

in the vicinity of a coil wire,

在線圈線的附近。

it induces an electrical current in that wire.

它在該導線上感應出電流。

Greg: And copper is a very conductive material

Greg: 而銅是一種很好的導電材料

'cause there's only one little measly electron

因為只有一個小小的電子

here in the outer shell that can be easily moved.

這裡的外殼，可以很容易地移動。

That's why copper wire is so good at having electrons

這就是為什麼銅線在擁有電子方面如此出色的原因

move in one direction along it

I thought you were just trying to figure out how to charge your phone with pee.

我以為你只是想知道如何用小便給手機充電。

I know. We got carried away.

We'll do this chamber with two electrodes.

我們將用兩個電極做這個試驗室。

Electrodes are conductors inserted into a substance

電極是插入物質中的導體

where electricity can enter or exit.

電力可以進入或離開的地方。

The electrons move in one direction

電子向一個方向移動

from the negative electrode to the positive one,

從負極到正極。

and then that creates an electric current.

然後就會產生電流。

Well, I'm so excited. Like, when do we put the pee in?

嗯，我太興奮了。比如，我們什麼時候把小便放進去？

I mean, I have to pee.

我的意思是，我得去尿尿。

'Tis a coffee pee. Don't judge any coloration.

So I'm in here.

所以我在這裡。

- It should be coming! - Oh, there's pee!

- 它應該來了！- 哦，有小便！

Oh, it's not too yellow.

哦，這不是太黃。

This is kinda gross, Greg.

這有點噁心，格雷格。

Boom, boom, boom. Pee.

轟隆隆，轟隆隆，轟隆隆。小便。

Okay.

It was a bit of a mess in there.

那裡面有點亂。

Okay, so we got some leakage.

好的，所以我們有一些洩漏。

So already we are getting electrons

是以，我們已經在獲得電子

passing through our direct circuit,

通過我們的直接電路。

which we can tell from this volt meter.

我們可以從這個電壓表看出。

And you're gonna see that it went from zero to two volts.

你會看到，它從零變成了兩伏。

So that's power coming from here?

所以那是來自這裡的力量？

Yes, and hopefully the bacteria's gonna go absolutely ham

是的，而且希望細菌會完全變成火腿。

- and release those electrons. - Okay.

- 並釋放這些電子。- 好的。

The pee construction is really cool.

小便的構造真的很酷。

The question remains, okay, Greg, does it work?

問題仍然是，好吧，格雷格，它有用嗎？

Hopefully we can pull it off,

希望我們能把它拉下來。

and hopefully we'll get some phone power.

並希望我們能得到一些電話的電量。

It's "Blair Witch." Aah!

( wolf howls )

( 狼嚎聲 )

The one part I didn't fully count on in the beginning

was just how much I personally would have to bike.

就是我個人要騎多少自行車。

Greg's gonna charge a phone, but I'm tasked with all the light bulbs, the laptops,

格雷格要給手機充電，但我的任務是負責所有的燈泡和筆記本電腦。

like, everything else in our cabin.

就像，我們機艙裡的其他東西。

As it's spinning, we're generating electrons

在它旋轉的過程中，我們產生了電子

that come through these wires and enter into a rectifier,

通過這些電線並進入整流器。

which is essentially pushing the electrons in one direction.

這實質上是將電子推向一個方向。

And then they hit our charger or regulator,

然後他們撞上了我們的充電器或調節器。

and this is gonna help us stabilize the voltage.

這將幫助我們穩定電壓。

'Cause I might be pedaling slow when I'm lazy...

因為我可能在偷懶的時候踩得很慢......。

Or fast when I have a lot of energy.
