00:00U.S. power usage on average is 500 gigawatts. China, just in solar, just in solar that can provide steady state power and batteries, can do half of the U.S. electricity output per year just with solar.
00:19Solar is by far the biggest source of energy. And actually, when you look beyond, even on Earth, but certainly beyond Earth, the sun rounds up to 100% of all energy. This is an important thing to consider.
00:37So, the sun is 99.8% of the mass of the solar system. Jupiter is about 0.1%, and everything else is miscellaneous.
00:48Now, even if you were to burn Jupiter in a thermonuclear reactor, the amount of energy produced by the sun would still round up to 100%, because Jupiter is only 0.1%.
01:03If you teleported three more Jupiters into our solar system and burnt three more Jupiters and everything else in the solar system, the sun's energy would still round up to 100%.
01:18So, it's really all about the sun. And that's why one of the things we'll be doing with SpaceX, you know, within a few years, is launching solar-powered AI satellites.
01:33Right.
01:33Because the space is really the source of immense power. And then you don't need to take up any room on Earth. There's so much room in space. And you can scale to enormous – I mean, you can scale to, I think, ultimately hundreds of terawatts a year.
01:55You and I have had these conversations before, but why don't you tell the audience what would it take for the United States and what type of geography would it take to have that solar field to electrify the United States?
02:12And then let me ask a question. Why aren't we doing it?
02:14Yeah. So, I mean, I guess a rough way to think about it is 100 miles by 100 miles, we'll call it 160 kilometers by 160 kilometers of solar is enough to power the entire United States.
02:29So, yeah, 100-mile by 100-mile area is – I mean, you could take basically a small corner of Utah, Nevada, New Mexico.
02:41Obviously, you wouldn't want it all in one place, but it is a very small percentage of the area of the U.S. to generate all of the electricity that the U.S. uses.
02:52And the same is true, actually, for Europe. You could take a small – you could take relatively unpopulated areas of, say, Spain and Sicily and generate all of the electricity power that Europe needs.
