马斯克谈专利与火箭回收

字幕原文

Since our primary competitors are national governments, the enforceability of patents is 由于我们的主要竞争对手是各国政府，专利的可执行性是

questionable. 值得怀疑的。

It's really interesting. 这真的很有趣。

But the big innovation is still ahead, 但真正的重大创新还在前方，

and you're working on it now. 而你现在正在为此努力。

Tell us about this. 给我们讲讲这个。

Right. 好的。

So 那么

the big innovation... 那个重大创新...

Let's roll that video, and you can talk us through it, 我们来播放那段视频，你可以给我们讲解一下，

what's happening here. 这里发生了什么。

Absolutely. 当然。

So 那么

the thing about 关于

rockets is that... 火箭的特点是...

They're all expandable. 它们都是一次性的。

All rockets that fly today are fully expandable. 今天所有飞行的火箭都是完全一次性的。

The space shuttle was an attempt at a reusable rocket, 航天飞机曾是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 但即使是航天飞机的主燃料箱每次都会被丢弃

time. 掉。

And the parts that were reusable 而那些可重复使用的部件

took a 需要一个

10,000-person 一万人的

group nine months to refurbish for flight. 团队花九个月时间进行翻新才能再次飞行。

So the space shuttle ended up costing a billion dollars per flight. 所以航天飞机最终每次飞行的成本高达十亿美元。

Obviously, that doesn't work very well for... 显然，这对...来说效果不佳。

So what just happened there? 那么刚才发生了什么？

We just saw something land? 我们刚才看到有东西着陆了？

That's right. 没错。

So 所以

it's important that the 重要的是，那些

rocket stages be able to come back, 火箭级能够返回，

to be able to return to the launch site 能够返回发射场

and be ready to launch again within a matter of hours. 并在数小时内准备好再次发射。

Wow. 哇。

Reusable rocket. 可重复使用的火箭。

Yes. 是的。

And so what a lot 很多人没有意识到的是，

of people don't realize is the cost of the fuel of the propellant 推进剂燃料的成本

is very small. 非常小。

It's much like on a jet. 这很像喷气式飞机。

So the cost of the propellant is about 0.3% of the cost of 所以推进剂的成本大约是火箭成本的0.3%

the rocket. 。
