未来的电能驱动飞机!

Electric Airplanes for the Future!

I hate to break this to you
我本不想告诉大家
but airplanes use a lot of gas
飞机用掉了大量的气体
and I’m saying gas, but they call it fuel when it’s airplanes
我所说的气体 在飞机上称之燃料
but basically it’s made from petroleum just like gasoline is.
它们像汽油一样 基本都是由石油提炼出来
A Boeing 747, for example,
拿波音747举个例子
uses about one gallon of fuel every second.
每秒大约用掉1加仑
So say you’re on a 10-hour long flight.
这样讲:如果你在一个十小时航程的航班上
That’s 36 000 gallons of fuel combusting under your butt
那么在你屁股下烧掉了36000加仑燃油
while you’re sitting there wishing you weren’t watching
而你正坐在它的上面 希望你没看到它
Water for Elephants or whatever you’re doing.
大象的眼泪或任何你正在做的事情
So, NASA, the Comparative Aircraft Flight Efficiency Foundation, and Google
所以,美国国家航空航天局(NASA)飞机飞行效率基金会,还有谷歌
put their heads together and they were like "Yikes, guys, we gotta do something about this.
把他们的精英聚在一起,打算 就像\n“是的 朋友们 在这件事儿上我们打算做些什么”
Surely there are some smart people in this great nation of ours that can improve this situation."
当然在我们这个伟大的国家\n有一些聪明人可以改变现状
And you know what?
你知道什么吗
When NASA and Google holler, all those smart aerospace engineer-y types
当NASA和谷歌抱怨时 \n所有这些聪明的航空工程师失败了
they come running.
他们开逃了
And you better believe there’s a contest involved.
你最好相信其中的这个争论
And here are the rules:
下面是一些规则:
The aircraft has to be able to travel 200 miles.
飞机必须能够飞行200英里
The aircraft has to be able to do that in less than two hours.
飞机必须在小于两个小时内完成它
And the aircraft has to use less than one gallon of fuel per occupant
而每个飞机乘员使用的燃料少于一加仑
or the equivalent in electricity.
或者同等电力
Of the three finalists who competed in the 2011 Green Flight challenge,
在2011年的绿色飞行挑战中的3位决赛选手
the 1st and 2nd place contestants both used electricity
一二名竞争者不约而同的使用了电力
and they both only used the equivalent of half a gallon of fuel per occupant.
他们都用了每个乘员少于同等一加仑燃料的能量
The winning aircraft, the Pipistrel Taurus G4 –
冠军飞机——the Pipistrel Taurus G4
which by the way looks like an aircraft that a really creative
顺便说一下看起来像一架非常形象的
8-year-old would draw minus the guns –
八岁的小孩子能画出来的枪
won both the speed and the efficiency categories of the event.
同时在速度和效率类别中赢得了比赛
Clocking a top speed of 107 miles per hour
最高速度达到107英里每小时
and an efficiency of 403 miles per gallon per occupant
每个成员403英里每加仑的同等效率
equivalent, of course, because remember it’s electric.
当然 因为记住它是电力的
That’s four times more efficient than a Boeing 747
那比波音747的效率高出了4倍
but not as fast and not as big, certainly, but way more efficient per passenger.
但没有那么快没有那么大 当然 \n但对每个乘客来说更加高效
And it’s not even using any gas! I mean fuel! Fuel, sorry.
而且他甚至没有用任何燃气 \n对不起我的意思是燃料 燃料
And that is why NASA just gave them $1.35 million and said
那就是为什么NASA给了他们135万美元
"Hey. Go start making electric planes."
说“嘿 来做电力飞机吧”
This is Hank Green and that was today’s Sci Show dose.
我是Hank Green 这是今天的Sci Show
