- 格雷格：世界是溫暖的。  - ( 嘆氣 )

情態副詞

Our cooling has officially been shut off.

我們的冷卻系統已經正式被關閉了。

程度副詞

- I'm so hot. - I'm making an off-grid fridge.

- 我太熱了。- 我正在做一個離網冰箱。

It's going to be complicated,  possibly amazing...

這將是複雜的，可能是驚人的...

- 真理的時刻。- ...或巨大的失敗。

Mitchell:  And I'm gonna cool  our bunky with paint.

米切爾。  我要用油漆來冷卻我們的床鋪。

But this isn't your  grandparents' white paint.  It's high tech stuff.

但這不是你祖父母的白漆。  這是高科技的東西。

Where's Greg? He's better at the manual labor.

格雷格在哪裡？他更擅長體力勞動。

- 哦！--那實際上是涼爽的空氣。

格雷格：我們真的可以冷卻我們的星球嗎？

Mitchell and Greg:  This is "Shut It Off ASAP."

米切爾和格雷格：這是 "儘快關閉它"。

Mitchell:  The world is warming,  and that excess heat

米切爾。  世界正在變暖，而這些多餘的熱量

is causing frequent wildfires,  droughts, crop failures,

正在造成頻繁的野火、乾旱和作物歉收。

optimized conditions  for disease vectors,

thermal-induced pollution--  the list goes on.

熱引起的汙染--這個名單還在繼續。

We need to keep ourselves cool.  And that is a problem.

我們需要讓自己保持冷靜。  而這是一個問題。

which is around three times  as much as shipping

So we have two universal,  potentially sustainable

是以，我們有兩個普遍的、可能是可持續的

off-grid cooling experiments  we want to try.

So there's been a trend in roofs in particular

是以，特別是在屋頂方面出現了一種趨勢

to think about the color they actually are,

and to figure out how much light and heat they are actually absorbing.

並計算出它們實際吸收了多少光和熱。

So I decided I'm going to find the whitest paint I can

是以，我決定要找到最白的油漆。

to see if we can get a big temperature drop inside

看看我們是否能讓室內溫度大幅下降

White paint has been used  to cool buildings

for thousands of years  across the Mediterranean,

幾千年來，在整個地中海地區。

to reflect the heat of the sun  away from their homes.

將太陽的熱量從他們的家裡反射出去。

These white structures,  although picturesque

這些白色的結構，雖然風景如畫

and quaint in the modern era,  serve a practical purpose.

而在現代社會中，古色古香的東西也有其實際用途。

I actually spoke with the creator of the whitest paint ever,

我實際上與有史以來最白的油漆的創造者談過。

including UV light, that we can't even see.

包括紫外線，我們甚至無法看到。

- about white paint   in particular. - It's my pleasure.

- 特別是關於白色油漆。- 這是我的榮幸。

We used a few different sort of innovations

我們使用了一些不同的創新方法

我們在七年內想出了這個辦法。

Sunlight has many different  wavelengths.

We eventually found that using different particle sizes will help you.

我們最終發現，使用不同的顆粒大小將有助於你。

Each particle size can scatter one wavelength.

每種顆粒大小都能散射一個波長。

它們能很好地反射所有的波長。

with cooling cities and potentially helping

against climate change and global warming?

We did an interesting analysis that you just need 1%

我們做了一個有趣的分析，你只需要1%的

of the Earth's surface covered with white paint.

Then that is enough  to cool the Earth down  back by 1 degree,

Our ice caps naturally reflect  incoming solar radiation,

我們的冰蓋自然地反映了進入的太陽輻射。

但隨著地球變暖，它們會融化。

the effect is hugely reduced, which warms the Earth further.

的效果大大降低，從而使地球進一步變暖。

Painting the top of buildings,  roadways, and even cars

在建築物、道路、甚至汽車的頂部作畫

can make up for this  and help fight climate change.

可以彌補這一點並幫助應對氣候變化。

I'm gonna be focusing on cooling our food.

I'll be putting it underground, under the soil,

我將把它放在地下，放在土壤下面。

We're also going to be having some evaporative cooling aspects,

我們還將有一些蒸發冷卻的方面。

in order to create this underground fridge.

- I have so many questions. - They'll be answered in   the video. Keep going.

- 我有這麼多問題。- 它們會在視頻中得到解答。繼續前進。

- 好的。 格雷格：哦，我們走吧。

The complexity of my build  means I need help

我的建築的複雜性意味著我需要幫助

我不僅需要他的電動工具技能。

They need electricity,  so we are powering them

他們需要電力，所以我們為他們提供電力。

The Peltier models help  to take heat away

從冷卻器裡面出來，並將其分散開來。

cools the outside  of the Peltier modules

And, lastly, for some  geothermal cooling,

we're burying the cooling box and evaporative cooling device

我們正在埋設冷卻箱和蒸發冷卻裝置
