The Mind Behind Tesla, SpaceX, SolarCity
Chris Anderson: Elon, what kind of crazy dream
克里斯·安德森:埃隆,这是一个多么疯狂的梦想
would persuade you to think of trying
会说服你考虑尝试
to take on the auto industry and build an all-electric car?
挑战汽车行业并制造全电动汽车?
Elon Musk: Well, it goes back to when I was in university.
埃隆·马斯克:嗯,这可以追溯到我上大学的时候。
I thought about, what are the problems that are most likely
我思考了一下,最有可能出现的问题是什么
to affect the future of the world or the future of humanity?
影响世界的未来还是人类的未来?
I think it's extremely important that we have sustainable transport
我认为我们拥有可持续的交通极其重要
and sustainable energy production.
和可持续能源生产。
That sort of overall sustainable energy problem
这种整体可持续能源问题
is the biggest problem that we have to solve this century,
是我们本世纪要解决的最大问题
independent of environmental concerns.
独立于环境问题。
In fact, even if producing CO2 was good for the environment,
事实上,即使产生二氧化碳对环境有好处,
given that we're going to run out of hydrocarbons,
考虑到我们即将耗尽碳氢化合物
we need to find some sustainable means of operating.
我们需要找到一些可持续的运作方式。
Most of American electricity comes from
美国大部分电力来自
burning fossil fuels.
燃烧化石燃料。
How can an electric car that plugs into that electricity help?
插入电力的电动汽车有何帮助?
Right.
正确的。
There's two elements to that answer.
这个答案有两个要素。
One is that, even if you take the same source fuel
一是,即使你采用相同来源的燃料
and produce power at the power plant
并在发电厂发电
and use it to charge electric cars, you're still better off.
并用它来给电动汽车充电,你的情况还是更好。
So if you take, say, natural gas,
所以如果你使用天然气
which is the most prevalent hydrocarbon source fuel,
这是最普遍的碳氢化合物源燃料,
if you burn that in a modern
如果你用现代的方式烧掉它
General Electric natural gas turbine,
通用电气天然气涡轮机、
you'll get about 60 percent efficiency.
您将获得大约 60% 的效率。
If you put that same fuel in an internal combustion engine car,
如果你将同样的燃料放入内燃机汽车中
you get about 20 percent efficiency.
您将获得大约 20% 的效率。
And the reason is, in the stationary power plant,
原因是,在固定发电厂中,
you can afford to have something that weighs a lot more,
你可以买得起更重的东西,
and you can take the waste heat
你可以利用余热
and run a steam turbine and generate
并运行蒸汽轮机并产生
a secondary power source.
辅助电源。
So in effect, even after you've taken transmission loss into account and everything,
所以实际上,即使你考虑了传输损耗和所有因素,
even using the same source fuel, you're at least twice as better off
即使使用相同的来源燃料,您的情况至少会好两倍
charging an electric car, then burning it at the power plant.
为电动汽车充电,然后在发电厂燃烧。
That scale delivers efficiency.
这种规模带来了效率。
And then the other point is, we have to have sustainable means
另一点是,我们必须有可持续的手段
of power generation anyway, electricity generation.
无论如何,发电。
So given that we have to solve sustainable electricity generation,
因此,鉴于我们必须解决可持续发电问题,
then it makes sense for us to have electric cars
那么我们拥有电动汽车就有意义了
as the mode of transport.
作为运输方式。
So we've got some video here
所以我们这里有一些视频
of the Tesla being assembled,
正在组装的特斯拉,
which, if we could play that first video --
如果我们可以播放第一个视频——
So what is innovative about this process in this vehicle?
那么这款车的这一工艺有何创新之处呢?
Sure.
当然。
So, in order to accelerate the advent of electric transport,
所以,为了加速电动交通的到来,
and I should say that I think, actually,
我应该说,我认为,实际上,
all modes of transport will become fully electric
所有交通方式都将实现全电动化
with the ironic exception of rockets.
具有讽刺意味的是,火箭除外。
There's just no way around Newton's third law.
没有办法绕过牛顿第三定律。
The question is how do you accelerate
问题是如何加速
the advent of electric transport?
电动交通的出现?
And in order to do that for cars, you have to come up with
为了在汽车上做到这一点,你必须想出
a really energy efficient car,
一辆真正节能的汽车,
so that means making it incredibly light,
所以这意味着让它变得非常轻,
and so what you're seeing here
所以你在这里看到的
is the only all-aluminum body and chassis car
是唯一一款全铝车身和底盘的汽车
made in North America.
北美制造。
In fact, we applied a lot of rocket design techniques
事实上,我们应用了很多火箭设计技术
to make the car light despite having a very large battery pack.
尽管有一个非常大的电池组,但仍使汽车变得轻。
And then it also has the lowest drag coefficient
然后它还具有最低的阻力系数
of any car of its size.
任何其尺寸的汽车。
So as a result, the energy usage is very low,
因此,能源使用量非常低,
and it has the most advanced battery pack,
并且它拥有最先进的电池组,
and that's what gives it the range that's competitive,
这就是它具有竞争力的范围,
so you can actually have on the order of a 250-mile range.
所以你实际上可以拥有大约 250 英里的续航里程。
I mean, those battery packs are incredibly heavy,
我的意思是,那些电池组非常重,
but you think the math can still work out intelligently --
但你认为数学仍然可以聪明地计算出来——
by combining light body, heavy battery,
通过结合轻机身、重电池,
you can still gain spectacular efficiency.
您仍然可以获得惊人的效率。
Exactly.
确切地。
The rest of the car has to be very light
汽车的其余部分必须非常轻
to offset the mass of the pack,
以抵消包装的质量,
and then you have to have a low drag coefficient so that you have good highway range.
然后你必须有一个低阻力系数,这样你才能有良好的高速公路行驶里程。
And in fact, customers of the Model S
事实上,Model S 的客户
are sort of competing with each other
有点互相竞争
to try to get the highest possible range.
尝试获得尽可能高的范围。
I think somebody recently got 420 miles out of a single charge.
我想最近有人一次充电就跑了 420 英里。
Bruno Bowden, who's here, did that,
布鲁诺·鲍登(Bruno Bowden)在这里,他做到了,
broke the world record.EM: Congratulations.
打破了世界纪录。 EM:恭喜。
That was the good news.
这是个好消息。
The bad news was that
坏消息是
to do it, he had to drive at 18 miles an hour constant speed
为了做到这一点,他必须以每小时 18 英里的速度匀速行驶
and got pulled over by the cops.
并被警察拦下。
(Laughter)
(笑声)
I mean, you can certainly drive --
我的意思是,你当然可以开车——
if you drive it 65 miles an hour,
如果你以每小时 65 英里的速度行驶
under normal conditions,
在正常情况下,
250 miles is a reasonable number.
250 英里是一个合理的数字。
Let's show that second video
让我们展示第二个视频
showing the Tesla in action on ice.
展示特斯拉在冰上行驶的情况。
Not at all a dig at The New York Times, this, by the way.
顺便说一下,这根本不是对《纽约时报》的挖苦。
What is the most surprising thing about the experience
这次经历中最令人惊讶的事情是什么
In creating an electric car,
在创造电动汽车时,
the responsiveness of the car is really incredible.
汽车的响应能力确实令人难以置信。
So we wanted really to have people feel as though
所以我们真的想让人们感觉好像
they've almost got to mind meld with the car,
他们几乎要和汽车融为一体,
so you just feel like you and the car are kind of one,
所以你会感觉你和车是一体的,
and as you corner and accelerate, it just happens,
当你转弯并加速时,它就发生了,
like the car has ESP.
就像汽车有ESP一样。
You can do that with an electric car because of its responsiveness.
您可以使用电动汽车来做到这一点,因为它的响应速度快。
You can't do that with a gasoline car.
汽油车无法做到这一点。
I think that's really a profound difference,
我认为这确实是一个深刻的区别
and people only experience that when they have a test drive.
人们只有在试驾时才会体验到这一点。
I mean, this is a beautiful but expensive car.
我的意思是,这是一辆漂亮但昂贵的汽车。
Is there a road map where this becomes
有没有一个路线图可以实现这一点
a mass-market vehicle?
大众市场车辆?
Yeah.
是的。
The goal of Tesla has always been
特斯拉的目标一直是
to have a sort of three-step process,
有一个三步过程,
where version one was an expensive car at low volume,
其中第一个版本是一辆价格昂贵但产量较低的汽车,
version two is medium priced and medium volume,
第二版是中等价格和中等数量,
and then version three would be low price, high volume.
然后第三版将是低价、高销量。
So we're at step two at this point.
所以我们现在处于第二步。
So we had a $100,000 sports car, which was the Roadster.
所以我们有一辆价值 10 万美元的跑车,那就是 Roadster。
Then we've got the Model S, which starts at around 50,000 dollars.
然后是 Model S,起价约为 50,000 美元。
And our third generation car, which should hopefully
还有我们的第三代汽车,希望它能够
be out in about three or four years
大约三四年后就会出局
will be a $30,000 car.
将是一辆价值 30,000 美元的汽车。
But whenever you've got really new technology,
但每当你拥有真正的新技术时
it generally takes about three major versions
一般需要三个主要版本左右
in order to make it a compelling mass-market product.
使其成为引人注目的大众市场产品。
And so I think we're making progress in that direction,
所以我认为我们正在朝这个方向取得进展,
and I feel confident that we'll get there.
我相信我们会实现这一目标。
I mean, right now, if you've got a short commute,
我的意思是,现在,如果你的通勤时间很短,
you can drive, you can get back, you can charge it at home.
你可以开车,你可以回来,你可以在家充电。
There isn't a huge nationwide network of charging stations now that are fast.
现在还没有庞大的全国性快速充电站网络。
Do you see that coming, really, truly,
你是否看到那即将到来,真的,真的,
or just on a few key routes?
或者只是在几条关键路线上?
There actually are far more charging stations
实际上有更多的充电站
than people realize,
比人们意识到的
and at Tesla we developed something
在特斯拉,我们开发了一些东西
called a Supercharging technology,
称为超级充电技术,
and we're offering that if you buy a Model S
如果您购买 Model S,我们将提供此优惠
And so this is something that maybe a lot of people don't realize.
所以这可能是很多人没有意识到的。
We actually have California and Nevada covered,
我们实际上覆盖了加利福尼亚州和内华达州,
and we've got the Eastern seaboard
我们有东海岸
from Boston to D.C. covered.
从波士顿到华盛顿特区。
By the end of this year, you'll be able to drive
到今年年底,你就可以开车了
from L.A.
来自洛杉矶
to New York
飞往纽约
just using the Supercharger network,
只需使用 Supercharger 网络,
which charges at five times the rate of anything else.
其收费是其他任何费用的五倍。
And the key thing is to have a ratio of drive to stop,
关键是要有一个驱动停止的比率,
to stop time, of about six or seven.
停止时间,大约有六七点。
So if you drive for three hours,
所以如果你开车三个小时
you want to stop for 20 or 30 minutes,
你想停下来20或30分钟,
because that's normally what people will stop for.
因为这通常是人们会停下来的地方。
So if you start a trip at 9 a.m.,
所以如果你早上9点开始旅行,
by noon you want to stop to have a bite to eat,
到了中午你想停下来吃点东西,
hit the restroom, coffee, and keep going.
去洗手间,喝杯咖啡,然后继续。
So your proposition to consumers is, for the full charge, it could take an hour.
因此,您向消费者提出的建议是,充满电可能需要一个小时。
So it's common -- don't expect to be out of here in 10 minutes.
所以这很常见——不要指望在 10 分钟内离开这里。
Wait for an hour, but the good news is,
等一个小时,但好消息是,
you're helping save the planet,
你正在帮助拯救地球,
and by the way, the electricity is free.
顺便说一句,电是免费的。
You don't pay anything.
您无需支付任何费用。
Actually, what we're expecting is for people
其实我们所期待的是人
to stop for about 20 to 30 minutes, not for an hour.
停下来大约20到30分钟,而不是一个小时。
It's actually better to drive for about maybe 160, 170 miles
实际上最好行驶大约 160、170 英里
and then stop for half an hour
然后停半个小时
and then keep going.
然后继续。
That's the natural cadence of a trip.
这就是旅行的自然节奏。
All right.
好的。
So this is only one string to your energy bow.
所以这只是你能量弓上的一根弦。
You've been working on this solar company SolarCity.
您一直在 SolarCity 这家太阳能公司工作。
What's unusual about that?
这有什么不寻常的吗?
Well, as I mentioned earlier,
嗯,正如我之前提到的,
we have to have sustainable electricity production
我们必须拥有可持续的电力生产
as well as consumption,
还有消费,
so I'm quite confident that the primary means
所以我非常有信心主要手段
of power generation will be solar.
发电将是太阳能。
I mean, it's really indirect fusion, is what it is.
我的意思是,这确实是间接融合,就是这样。
We've got this giant fusion generator in the sky called the sun,
我们在天空中有一个巨大的聚变发生器,称为太阳,
and we just need to tap a little bit of that energy
我们只需要利用一点能量
for purposes of human civilization.
为了人类文明的目的。
What most people know but don't realize they know
大多数人都知道但没有意识到他们知道的事情
is that the world is almost entirely solar-powered already.
世界几乎已经完全由太阳能驱动。
If the sun wasn't there, we'd be a frozen ice ball
如果没有太阳,我们就会变成一个冰冻的冰球
at three degrees Kelvin,
在三开尔文温度下,
and the sun powers the entire system of precipitation.
太阳为整个降水系统提供动力。
The whole ecosystem is solar-powered.
整个生态系统都是由太阳能供电的。
But in a gallon of gasoline, you have,
但在一加仑汽油中,你有,
effectively, thousands of years of sun power
有效地利用了数千年的太阳能
compressed into a small space,
压缩成一个狭小的空间,
so it's hard to make the numbers work right now on solar,
所以现在很难让这些数字在太阳能上发挥作用,
and to remotely compete with, for example, natural gas,
并与天然气等进行远程竞争,
fracked natural gas.
水力压裂天然气。
How are you going to build a business here?
您打算如何在这里开展业务?
Well actually, I'm confident that solar
事实上,我对太阳能很有信心
will beat everything, hands down, including natural gas.
毫无疑问,它将击败一切,包括天然气。
It must, actually.
事实上,它必须如此。
If it doesn't, we're in deep trouble.
如果不这样做,我们就有大麻烦了。
But you're not selling solar panels to consumers.
但你并不是向消费者出售太阳能电池板。
No, we actually are.
不,我们确实是。
You can buy a solar system
你可以买一个太阳能系统
or you can lease a solar system.
或者你可以租用一个太阳能系统。
Most people choose to lease.
大多数人选择租赁。
And the thing about solar power is that
关于太阳能的事情是
it doesn't have any feed stock or operational costs,
它没有任何原料或运营成本,
so once it's installed, it's just there.
所以一旦安装完毕,它就在那里。
It works for decades.
它可以工作几十年。
It'll work for probably a century.
它可能会工作一个世纪。
So therefore, the key thing to do is to get the cost
因此,关键是要获取成本
of that initial installation low,
初始安装较低,
and then get the cost of the financing low,
然后降低融资成本,
because that interest -- those are the two factors that drive the cost of solar.
因为这种兴趣是推动太阳能成本的两个因素。
And we've made huge progress in that direction,
我们在这个方向上取得了巨大的进步
and that's why I'm confident we'll actually beat natural gas.
这就是为什么我相信我们实际上会击败天然气。
So your current proposition to consumers is,
所以你目前向消费者提出的建议是,
don't pay so much up front.
不要预先支付那么多费用。
Zero.CA: Pay zero up front.
Zero.CA:预先支付零费用。
We will install panels on your roof.
我们将在您的屋顶上安装面板。
You will then pay, how long is a typical lease?
然后您将付款,典型的租约是多长?
Typical leases are 20 years,
一般租期为 20 年,
but the value proposition is, as you're sort of alluding to, quite straightforward.
但正如您所提到的,价值主张非常简单。
It's no money down, and your utility bill decreases.
无需首付,您的水电费也会减少。
So that seems like a win for the consumer.
所以这对消费者来说似乎是一场胜利。
No risk, you'll pay less than you're paying now.
没有风险,您支付的费用将低于现在支付的费用。
For you, the dream here then is that --
对你来说,这里的梦想是——
I mean, who owns the electricity from those panels for the longer term?
我的意思是,从长远来看,谁拥有这些电池板的电力?
I mean, how do you, the company, benefit?
我的意思是,你和公司如何受益?
Well, essentially,
嗯,本质上,
SolarCity raises a chunk of capital
SolarCity筹集大量资金
from say, a company or a bank.
例如,来自公司或银行。
Google is one of our big partners here.
谷歌是我们这里的重要合作伙伴之一。
And they have an expected return on that capital.
他们对该资本有预期回报。
With that capital, SolarCity purchases and installs the panel on the roof
SolarCity 利用这笔资金购买了太阳能电池板并将其安装在屋顶上
and then charges the homeowner or business owner
然后向房主或企业主收费
a monthly lease payment, which is less than the utility bill.
每月支付的租金,少于水电费。
But you yourself get a long-term commercial benefit from that power.
但你自己可以从这种力量中获得长期的商业利益。
You're kind of building a new type of distributed utility.
您正在构建一种新型的分布式实用程序。
Exactly.
确切地。
What it amounts to
它相当于什么
is a giant distributed utility.
是一个巨大的分布式实用程序。
I think it's a good thing, because utilities
我认为这是一件好事,因为公用事业
have been this monopoly, and people haven't had any choice.
一直如此垄断,人们没有任何选择。
So effectively it's the first time
这么有效这是第一次
there's been competition for this monopoly,
存在着对这种垄断的竞争,
because the utilities have been the only ones
因为公用事业是唯一的
that owned those power distribution lines, but now it's on your roof.
曾经拥有这些配电线路,但现在它在你的屋顶上。
So I think it's actually very empowering
所以我认为这实际上非常有力量
for homeowners and businesses.
对于房主和企业。
And you really picture a future
你确实描绘了未来
where a majority of power in America,
美国的大多数权力,
within a decade or two, or within your lifetime, it goes solar?
一两年内,或者在你的一生中,它会变成太阳能吗?
I'm extremely confident that solar will be at least a plurality of power,
我非常有信心太阳能至少会成为多种能源,
and most likely a majority,
并且很可能是大多数,
and I predict it will be a plurality in less than 20 years.
我预测不到 20 年就会实现多数派。
I made that bet with someone —CA: Definition of plurality is?
我和某人打了赌——CA:复数的定义是?
More from solar than any other source.
太阳能比任何其他来源都更多。
Ah.
啊。
Who did you make the bet with?
你和谁打赌了?
With a friend who will remain nameless.
和一个将保持匿名的朋友。
Just between us.
就在我们之间。
(Laughter)
(笑声)
I made that bet, I think, two or three years ago,
我想,两三年前我就下了这个赌注
so in roughly 18 years,
所以在大约18年的时间里
I think we'll see more power from solar than any other source.
我认为我们将看到太阳能比任何其他来源都多。
All right, so let's go back to another bet that you made
好吧,让我们回到你的另一个赌注
with yourself, I guess, a kind of crazy bet.
我想,和你自己打赌是一种疯狂的赌注。
You'd made some money from the sale of PayPal.
您通过出售 PayPal 赚了一些钱。
You decided to build a space company.
您决定建立一家太空公司。
Why on Earth would someone do that?
到底为什么有人会这么做?
I got that question a lot, that's true.
我经常被问到这个问题,确实如此。
People would say, "Did you hear the joke about the guy
人们会说,“你听过关于这个人的笑话吗?
who made a small fortune in the space industry?"
谁在航天工业中发了一笔小财?”
Obviously, "He started with a large one," is the punchline.
显然,“他从一个大的开始”是笑点。
And so I tell people, well, I was trying to figure out
所以我告诉人们,好吧,我试图弄清楚
the fastest way to turn a large fortune into a small one.
将大笔财富变成小笔财富的最快方法。
And they'd look at me, like, "Is he serious?"
他们会看着我,就像,“他是认真的吗?”
And strangely, you were.
奇怪的是,你确实是。
So what happened?
那么发生了什么?
It was a close call.
这是一次千钧一发的机会。
Things almost didn't work out.
事情几乎没有进展。
We came very close to failure,
我们非常接近失败,
but we managed to get through that point in 2008.
但我们在 2008 年成功度过了这一关。
The goal of SpaceX is to try to advance rocket technology,
SpaceX的目标是尝试推进火箭技术,
and in particular to try to crack a problem
尤其是尝试解决问题
that I think is vital
我认为至关重要
for humanity to become a space-faring civilization,
让人类成为太空文明,
which is to have a rapidly and fully reusable rocket.
这就是拥有一个快速且完全可重复使用的火箭。
Would humanity become a space-faring civilization?
人类会成为太空文明吗?
So that was a dream of yours, in a way, from a young age?
所以从某种程度上来说,这是你从小就有的梦想?
You've dreamed of Mars and beyond?
您梦想过火星及更远的地方吗?
I did build rockets when I was a kid,
我小时候确实造过火箭
but I didn't think I'd be involved in this.
但我没想到我会参与其中。
It was really more from the standpoint of
这确实更多是从
what are the things that need to happen in order for
需要发生哪些事情才能
the future to be an exciting and inspiring one?
未来会是一个令人兴奋和鼓舞人心的未来吗?
And I really think there's a fundamental difference,
我真的认为有一个根本的区别
if you sort of look into the future,
如果你展望未来
between a humanity that is a space-faring civilization,
在一个太空文明的人类之间,
that's out there exploring the stars, on multiple planets,
在那里探索恒星,在多个行星上,
and I think that's really exciting,
我认为这真的很令人兴奋
compared with one where we are forever confined to Earth
与我们永远被限制在地球上的地方相比
until some eventual extinction event.
直到一些最终的灭绝事件。
So you've somehow slashed the cost of building
所以你以某种方式削减了建筑成本
a rocket by 75 percent, depending on how you calculate it.
火箭提高了 75%,具体取决于你如何计算。
How on Earth have you done that?
你到底是怎么做到的?
NASA has been doing this for years.
美国宇航局多年来一直在这样做。
How have you done this?
你是怎么做到的?
Well, we've made significant advances
嗯,我们已经取得了重大进展
in the technology of the airframe, the engines,
在机身、发动机技术方面,
the electronics and the launch operation.
电子设备和发射操作。
There's a long list of innovations
有一长串的创新
that we've come up with there
我们在那里想出了
that are a little difficult to communicate in this talk, but --
在这次演讲中沟通有点困难,但是——
Not least because you could still get copied, right?
尤其是因为你仍然可能被复制,对吧?
You haven't patented this stuff.
你还没有为这个东西申请专利。
It's really interesting to me.
这对我来说真的很有趣。
No, we don't patent.CA: You didn't patent because you think it's
不,我们不申请专利。CA:您没有申请专利,因为您认为它是
more dangerous to patent than not to patent.
申请专利比不申请专利更危险。
Since our primary competitors are national governments,
由于我们的主要竞争对手是各国政府,
the enforceability of patents is questionable.(Laughter) (Applause)
专利的可执行性值得怀疑。(笑声)(掌声)
That's really, really interesting.
这真的非常非常有趣。
But the big innovation is still ahead,
但大创新仍在前方,
and you're working on it now.
而你现在正在努力。
Tell us about this.
告诉我们这件事。
Right, so the big innovation—
是的,所以重大创新——
In fact, let's roll that video and you can talk us through it, what's happening here.
事实上,让我们播放该视频,您可以向我们讲述这里发生的事情。
Absolutely.
绝对地。
So the thing about rockets is that
所以关于火箭的事情是
they're all expendable.
他们都是消耗品。
All rockets that fly today are fully expendable.
今天飞行的所有火箭都是完全消耗性的。
The space shuttle was an attempt at a reusable rocket,
航天飞机是对可重复使用火箭的一次尝试
but even the main tank of the space shuttle was thrown away every time,
但连航天飞机的主油箱每次都被扔掉,
and the parts that were reusable
以及可重复使用的部件
took a 10,000-person group nine months to refurbish for flight.
一个 10,000 人的团队花了九个月的时间才完成飞行翻新。
So the space shuttle ended up costing a billion dollars per flight.
因此,航天飞机每次飞行最终花费了 10 亿美元。
Obviously that doesn't work very well for —
显然这对于——
What just happened there?
那里刚刚发生了什么?
We just saw something land?
我们刚刚看到了陆地上的东西?
That's right.
这是正确的。
So it's important that the rocket stages
所以火箭级很重要
be able to come back, to be able to return to the launch site
能够回来,能够回到发射场
and be ready to launch again within a matter of hours.
并在几小时内准备好再次启动。
Wow.
哇。
Reusable rockets.EM: Yes.
可重复使用的火箭。EM:是的。
(Applause)
(掌声)
And so what a lot of people don't realize is,
所以很多人没有意识到的是,
the cost of the fuel, of the propellant, is very small.
燃料、推进剂的成本非常低。
It's much like on a jet.
这很像在喷气式飞机上。
So the cost of the propellant is about .3 percent
所以推进剂的成本约为 0.3%
of the cost of the rocket.
火箭的成本。
So it's possible to achieve, let's say,
所以可以说,
roughly 100-fold improvement in the cost of spaceflight
航天成本降低约 100 倍
if you can effectively reuse the rocket.
如果你能有效地重复利用火箭。
That's why it's so important.
这就是为什么它如此重要。
Every mode of transport that we use,
我们使用的每一种交通方式,
whether it's planes, trains, automobiles, bikes, horses,
无论是飞机、火车、汽车、自行车、马匹,
is reusable, but not rockets.
可以重复使用,但不能火箭。
So we must solve this problem in order to become a space-faring civilization.
所以我们必须解决这个问题才能成为太空文明。
You asked me the question earlier
你之前问过我这个问题
