The first  fuel-powered automobile  was invented in 1885

1885年發明了第一輛以燃料為動力的汽車。

由梅賽德斯-奔馳的卡爾-奔馳。

who applied for a patent  for his three wheeled,

他為自己的三輪車申請了專利。

gasoline-powered Motorwagen  the following year.

翌年，以汽油為動力的Motorwagen汽車正式上市。

like this electric car that was invented in the 1830s,

比如這種19世紀30年代發明的電動車。

which had been rolling around  France way back in 1769.

早在1769年就已經在法國滾滾而來。

that the world's first  solar-powered vehicle  was demonstrated.

展示了世界上第一輛太陽能汽車。

a drivable solar-powered car  was finally unveiled.

一輛可駕駛的太陽能汽車終於亮相了。

Turns out, building a vehicle that's powered by the sun

原來，製造一輛以太陽為動力的汽車。

Or really old carbon, also known as fossil fuel.

或者真正的老碳，也就是化石燃料。

But while  commercially available  solar cars

但是，雖然商業化的太陽能汽車

what seems like an impossible piece of technology

And these solar cars  are capable of going faster

而且這些太陽能汽車能夠跑得更快

What's more, the technology  in today's solar vehicles

更重要的是，今天的太陽能汽車的技術。

could drive us all toward  a cleaner, greener future.

可以推動我們所有人走向一個更清潔、更綠色的未來。

So in this episode, we take  a look under the hood

所以在本期節目中，我們來看看引擎蓋下的情況。

of one of the world's  fastest solar cars

世界上最快的太陽能汽車之一，其生產過程也是如此。

太陽能汽車到底是如何工作的？

Like me, you've probably thought of solar cars

和我一樣，你可能已經想到了太陽能汽車。

Like, a technology  so futuristic and complex

就像，一個如此未來主義和複雜的技術。

that it feels like  it can't actually exist  in the real world.

這感覺就像它不可能真正存在於現實世界中一樣。

好吧，這是一輛太陽能汽車模型。

It's about 8cm long, just over three inches,

so it's even smaller than that Sunmobile.

But it's got all the same major components.

that converts those photons into electricity.

We actually covered that whole process in detail

其實整個過程我們都有詳細介紹

in a previous chapter, so check that out.

into mechanical energy, which propels the car.

轉化為機械能，推動汽車的發展。

Now, as long as the car's solar cells are exposed to sunlight,

現在，只要汽車的太陽能電池暴露在陽光下。

there's enough power to keep the wheels turning

and yes, it is a very basic demonstration,

是的，這是一個非常基本的示範。

it shows how solar cars of the past worked.

它顯示了過去的太陽能汽車是如何工作的。

So you can see why solar cars of the past

所以，你可以看到為什麼過去的太陽能汽車。

have not been considered a viable option.

尚未被認為是一個可行的選擇。

Luckily, today's solar cars are a bit more sophisticated.

幸運的是，如今的太陽能汽車已經比較成熟了。

The solar racers competing in the world Solar Challenge, for example,

例如，參加世界太陽能挑戰賽的太陽能賽車手。

don't just use the latest in photovoltaic technology,

in design, engineering  and battery technology.

在設計、工程和電池技術方面。

of the racing team  from Stanford University.

My name is Cori Brendel. I was the team lead

for the 2019 Stanford Solar Car Project cycle.

為2019年斯坦福太陽能汽車項目週期。

and throughout  the race preparation time,

I ended up in a kind of  jack-of-all-trades role.

我最後成了一種萬事通的角色。

Julia was actually behind the wheel for the 2019 race,

which, unfortunately,  didn't go so well  for the Stanford team.

其中，不幸的是，斯坦福大學隊並沒有那麼順利。

I think, like, right as we got outside the city,

我想，就像，當我們到了城外。

I remember watching  as they pulled the panel off,

我記得我看著他們把面板拉下來。

had a disappointing  performance in 2019,

所以我們總是帶著想贏的心情去的。

But I think one of the big principles underlying the team

但我認為，團隊的一個重要原則就是

for what we can do with engineering and technology.

為我們能用工程和技術做什麼。
