1
00:00:00,320 --> 00:00:02,560
or twenty-eight, how long before impact?

2
00:00:04,160 --> 00:00:08,320
Yeah, the so yeah, maybe just just went time on open five.

3
00:00:09,840 --> 00:00:16,000
Yes, there's there there's currently people have tested NVIDIA GPUs.

4
00:00:16,080 --> 00:00:30,000
So there's a satellite with an NVIDIA GPU up there that relaunched and and there's satellite in the recent release with a satellite in the recent release with a satellite and these are and bum bum bum bum bum bum bum bum bum bum bum bum bum bum bum bum bum bum bum

5
00:01:00,160 --> 00:01:10,800
Scale, you really need to go to space because there just isn't enough power in on the ground to realistically get to those levels per year.

6
00:01:11,440 --> 00:01:20,080
Just as a frame of reference, the power output, the average power average power consumption in the United States is just over 500 gigawatts.

7
00:01:21,680 --> 00:01:26,480
So if you look, if you if you know the the the the peak power in the United States is roughly 1.

8
00:01:26,720 --> 00:01:29,840
2 terawatts, but average power consumption.

9
00:01:30,080 --> 00:01:31,680
Is just over 500 gigawatts.

10
00:01:31,920 --> 00:01:44,320
So you can really see that like if if you're doing, say, 200 gigawatts a year of AI, that would be like doing a 40% increase in the entire US power grid every year.

11
00:01:45,120 --> 00:01:47,360
Which is simply not feasible.

12
00:01:49,680 --> 00:01:59,760
And when you take solar panels and you and you put them in space, because it's essentially it's always sunny in space, and the solar panels can always face the sun directly.

13
00:02:00,320 --> 00:02:02,560
They're not off angle to the sun.

14
00:02:06,160 --> 00:02:10,320
And you don't have atmospheric attenuation of solar power.

15
00:02:10,720 --> 00:02:14,160
So you get 30% more solar power in space.

16
00:02:14,240 --> 00:02:15,120
It's sunny all the time.

17
00:02:15,200 --> 00:02:16,400
There's no seasonality.

18
00:02:16,800 --> 00:02:22,320
You don't really need you can have you can get away with a very tiny battery pack because you don't need to last through the night.

19
00:02:23,520 --> 00:02:29,120
The cost of of intelligence in space is dramatically less than the ground.

20
00:02:29,200 --> 00:02:29,840
Once you have

21
00:02:30,320 --> 00:02:32,480
A low cost per ton to orbit.

22
00:02:32,720 --> 00:02:43,840
So Starship, because it will be the first fully reusable rocket, will lower the cost of access to space by a factor of a hundred, or maybe more.

23
00:02:44,320 --> 00:02:57,440
I I I think actually, in the limit, the w I mean maybe we're within the same probably two or three years, the cost of a ton to orbit will be less than the cost of air freight from California to Australia.

24
00:02:57,680 --> 00:02:58,640
From California to Australia.

25
00:03:00,400 --> 00:03:07,760
From that 2010, the cost to get to orbit was $18,500 a kilogram.

26
00:03:08,240 --> 00:03:10,640
That was because you use a rocket one time.

27
00:03:11,040 --> 00:03:20,960
And then when we came up with a rocket Falcon 9, you could use over and over again, it became, I think it was $2,500, and then it went to $1,500.

28
00:03:21,280 --> 00:03:24,240
And now it's going to go to $100 or $15 or $15?

29
00:03:24,880 --> 00:03:28,720
I think we'd get to under $100 a kilogram to orbit.

30
00:03:30,000 --> 00:03:37,920
So that i it's it's important to just appreciate how profound full reusability is.

31
00:03:38,240 --> 00:03:45,520
so with with Falcon nine, we have I I guess probably around eighty percent of usability.

32
00:03:45,600 --> 00:03:48,000
So the booster is you know comes back and lands.

33
00:03:48,080 --> 00:03:51,280
If you've probably seen the videos of the Falcon I booster landing.

34
00:03:51,360 --> 00:03:59,840
And then the fairing or NOSCone that contains the satellites, that that th those th those fairing halves land by parachute in the ocean.

35
00:04:00,080 --> 00:04:01,440
And we refly those.

36
00:04:01,680 --> 00:04:04,400
But we do not refly the upper stage.

37
00:04:04,880 --> 00:04:07,920
So we're unable to recover the upper stage of Falcon 9.

38
00:04:08,000 --> 00:04:11,680
And the cost of the upper stage is roughly the cost of a medium-sized jet.

39
00:04:12,000 --> 00:04:17,040
So that means the the minimum cost per flight from Falcon 9 is a medium-sized jet.

40
00:04:17,120 --> 00:04:19,360
Now that's still much better than anything else.

41
00:04:19,920 --> 00:04:26,400
But it's safe to say that there wouldn't be a lot of air travel if every time you flew somewhere you had to throw away a medium-sized jet.

42
00:04:28,800 --> 00:04:29,760
But like I think I'll drive.

43
00:04:35,760 --> 00:04:42,320
So so now with with Starship, the the entire system is designed for reusability.

44
00:04:42,960 --> 00:04:48,720
So the and and and and not just reusability but but extremely rapid reusability.

45
00:04:48,960 --> 00:04:57,520
The the reason to to to catch the booster and the ship with the tower arms, we call the chocolate the chopsticks, it's kinda like Mr.

46
00:04:57,680 --> 00:04:59,840
Miyagi and Karate Kid catching the fly.

47
00:05:00,160 --> 00:05:01,600
It just make it bigger.

48
00:05:01,840 --> 00:05:08,080
and the the reason for that is is is that the rocket takes off from the launch pad.

49
00:05:08,640 --> 00:05:18,080
So the rocket is placed on the launch pad by the tower, and then it is caught by those same tower arms and placed back on the launch pad when it returns from space.

50
00:05:19,120 --> 00:05:23,680
So you don't just have full reusability, you have extremely rapid reusability.

51
00:05:23,840 --> 00:05:28,480
You really couldn't get faster reusability than landing back where you took off.

52
00:05:30,640 --> 00:05:41,120
And th thus in principle would would allow us to re-fly the the rocket, the giant booster, the super heavy booster, once an hour.

53
00:05:42,320 --> 00:05:44,560
10,000 launches a year.

54
00:05:46,400 --> 00:05:46,900
Yes.

55
00:05:47,120 --> 00:05:49,280
Probably more in the in the end, but yes.

56
00:05:49,520 --> 00:05:51,360
more than a launch an hour.

57
00:05:52,880 --> 00:05:59,280
So when I was young, people would line up to watch every now, very rarely, a rocket.

58
00:06:00,080 --> 00:06:01,440
We can do one in an hour.

59
00:06:01,680 --> 00:06:04,080
Doesn't even make newspapers anymore.

60
00:06:05,120 --> 00:06:05,680
Yes.

61
00:06:06,080 --> 00:06:10,160
Well, this will be quite in quite I mean, you really want to watch this one.

62
00:06:10,320 --> 00:06:11,360
This one's cool.

63
00:06:11,520 --> 00:06:18,640
I mean it's it's the largest flying object ever made.

64
00:06:18,800 --> 00:06:24,800
And and it's the highest thrust object ever made by humans of any kind whatsoever.

65
00:06:25,840 --> 00:06:29,840
so yeah, this thing weighs over five thousand tons.

66
00:06:30,320 --> 00:06:32,400
on lift wolf and it's going straight up.

67
00:06:37,280 --> 00:06:42,960
and and then and then that then that then that giant thing comes back you know fly comes back from space.

68
00:06:44,000 --> 00:06:46,400
You know like five minutes after lift wolf.

69
00:06:46,560 --> 00:06:49,040
That that booster is coming down one way or another.

70
00:06:49,280 --> 00:06:53,120
It's gonna you know hopefully in a good way, but it's coming down one way or another.

71
00:06:53,200 --> 00:06:54,560
So excitement is guaranteed.

72
00:06:54,640 --> 00:06:59,840
Success success is not always guaranteed, but excitement's always it's very cool when you see it come back.

73
00:07:00,240 --> 00:07:02,800
And lands in the same place where it took off.

74
00:07:03,520 --> 00:07:04,020
Yeah.

75
00:07:06,800 --> 00:07:08,240
It looks crazy.

76
00:07:10,720 --> 00:07:14,560
when I first proposed this to the team, they looked at me like I was lost my mind.

77
00:07:14,640 --> 00:07:16,720
But I'm like, look, I think this can be done, you know.

78
00:07:16,880 --> 00:07:20,800
there's there's nothing that's preventing it from happening from a physics standpoint.

79
00:07:21,600 --> 00:07:27,600
And and back in the phone, the only thing I can think of that would be slightly better than crashing it with the tower, which would be literally landing.

80
00:07:30,240 --> 00:07:31,680
Or whatever you think is best for the project.

81
00:07:37,520 --> 00:07:41,360
So if we if we just catch it with the arms, that's that's a little better.

82
00:07:41,440 --> 00:07:45,680
because we don't smash the launch pad necessarily if if something goes wrong.

83
00:07:45,920 --> 00:07:55,600
but it's that's the difference of minutes between catching with the arms, catching with the and simply landing in the actual launch pad it took took off from.

84
00:07:55,920 --> 00:07:59,840
now the the the much harder than

85
00:08:03,440 --> 00:08:11,040
And the you know the the the ship we we've gotta have also we there there's a lot of things that have to be done that have never been never been done before.

86
00:08:11,200 --> 00:08:15,440
No one has ever made a truly reusable orbital heat shield.

87
00:08:15,680 --> 00:08:16,720
So the the the the
