Here’s Elon Musk explaining that SpaceX could launch up to one terawatt per year of AI compute capacity into Earth orbit — equivalent to the power output of roughly 1,000 nuclear power plants. “The next step beyond Earth data centers is our Earth orbital data centers. And we'll be...

🚨NEW: Elon Musk explains the reason behind the SpaceX and xAI merger. "In order to understand the universe, you must explore the universe. That's the motivation behind the combination of SpaceX and xAI is to accelerate humanity's future in understanding the universe and extending the light of consciousness to the stars. So in the grand scheme of things, when you look at how much energy Earth is actually using for civilization, we're only right now using, call it roughly 1% of the potential energy of Earth. And if we wanted to use even a millionth of the sun's energy, that would be roughly a million times more energy than civilization currently uses. The only way to access that energy, the energy of the sun is to extend beyond Earth. Earth is really a tiny, tiny dust Mote in a vast darkness. The sun is 99.8% of all mass in the solar system, so you have to expand beyond the tiny dust mode that is earth to make any significant dent in using the sun's energy like says, you'd have to expand roughly a million times just to get to 1,000,000th of our sun's energy, and then going beyond that, exploring extending to the Galaxy. So the the next step beyond Earth data centers is our Earth orbital data centers, and we'll be launching with SpaceX orbital data centers at the 100 to 200 gigawatt per year level, not cumulative, I mean, per year. And ultimately, we see a path to maybe launching as much as a terawatt per year of compute from Earth."

Bro… Elon just laid out the blueprint on how xAI and SpaceX are getting to 1,000+ gigawatts per year and beyond, in his closing statement at the xAI all-hands! IMO, this is why there will be no competition in space. 1/ Earth Supercomputers (Now) Build Memphis cluster to get us to >1 GW of power. “We’re only right now using roughly one percent of the potential energy of Earth.” Plan: • 330,000+ Grace Blackwell GPUs • ~1M H100-equivalent compute • 1 gigawatt draw at full scale • Built in <1 year • Tesla Megapacks stabilizing energy FYI, most AI companies are operating in hundreds of megawatts, yet xAI is already at a utility-scale gigawatt compute. 2/ Orbital Datacenters (Soon) Get to 100-200 GW per year launched into orbit with a path to ~1 terawatt (1,000 GW) total from Earth launches. “The next step beyond Earth data centers is our Earth orbital datacenters… launching at the 100-200 gigawatt per year level. Not cumulative, I mean per year.” Benefits: • Continuous solar exposure • No land constraints • No terrestrial grid bottlenecks • Virtually unlimited horizontal expansion FYI, 100–200 GW per year is equivalent to adding multiple large nation-scale grids annually. 3/ Moon Factories + Mass Driver (Mid Future) Get to 1,000+ GW per year, several orders of magnitude beyond Earth. “In order to do that you have to go to the Moon… We are actually going to have a mass driver on the Moon.” Plan: • Lunar factories build AI satellites • Electromagnetic mass driver launches them without fuel • Low lunar gravity reduces launch energy requirements • Scales far beyond Earth’s physical constraints FYI, this is when industrialized compute begins manufacturing off Earth. 4/ Solar System & Beyond (Long Term Future) Today the sun outputs ~3.8 × 10²⁶ watts “If we wanted to use even a millionth of the Sun’s energy, that would be roughly a million times more energy than civilization currently uses.” This means • 0.000001 of the Sun’s output = ~1,000,000 × today’s global Earth energy usage. 🤯 “Earth is really a tiny, tiny dust mote in a vast darkness… The Sun is 99.8% of all mass in the solar system.” To access that scale: • Moon manufacturing • Mars expansion • Solar-orbit compute clusters • Eventually tapping meaningful fractions of stellar output So… the blueprint to get here is 1/ Start at 1 GW. 2/ Scale to 1 TW. 3/ Scale to 1,000+ GW per year. 4/ Then expand toward fractions of the Sun itself. It’s clear that xAI + SpaceX is building the AI infrastructure and pathway to a stellar-scale energy civilization. I really hope I’m still alive to witness all this.

elon musk just sat down with his SpaceX team and explained exactly how they're going to turn humanity into a kardashev type 2 civilization it's one of the most insane things i've ever watched: 1. humanity currently uses less than one trillionth of the sun's energy output. a trillion is a million times a million. on the kardashev scale, the one physicists use to measure how advanced a civilization actually is, we are not even registering. we are effectively non-existent. 2. starship is the first rocket in history designed to be fully reusable. every other mode of transport, cars, planes, ships, bicycles, you take reusability for granted. rockets have always been thrown away after one use. if you had to throw away the plane after every flight, almost nobody would be flying. 3. spacex currently launches 85 to 90% of all mass to orbit on earth. the rest of the world, including most of the us, accounts for maybe 5 to 7%. that's before starship even gets going. 4. the plan is to go from 2,500 tons to orbit per year to a million tons per year. in roughly 3 years. that's not a projection. that's the internal target. 5. data centers are moving to space. by end of next year spacex is targeting 1 gigawatt of ai compute in orbit. then 10x every year after that. 10 gigawatts in 2.5 years. 100 gigawatts in 3.5 years. a terawatt eventually, which is twice the entire electricity consumption of the united states. 6. the ai satellite is actually simpler to build than a starlink satellite. it's mostly solar panels, a radiator, and a rack of gpus. the hard part was already solved building starlink. they're just making it bigger. 7. latency from orbit is about 3 milliseconds. light travels 300 km per millisecond. some people assume orbital compute means high latency. it doesn't. it's 3 milliseconds away. 8. the terafab will be 100 million square feet. ten times the size of the tesla gigafactory texas. the entire global chip industry is on track to hit maybe 100 gigawatts of ai compute per year. a terawatt requires a completely different order of manufacturing. that's why they're building it themselves. 9. to go beyond a terawatt you have to go to the moon. no atmosphere. one-sixth earth's gravity. you manufacture solar panels and radiators directly from moon materials. then you launch ai satellites into deep space using an electromagnetic rail gun. no rocket needed. musk calls this the mass driver. this is the next step on the actual roadmap. 10. if enough mass is going to the moon to run a rail gun operation at that scale, it also means regular people can go. musk's exact words: "i think everyone should go to the moon at least once." 11. the ai satellite has about a terabit of laser link connectivity. it connects to the starlink constellation which then sends data to the ground using frequencies that penetrate clouds and even roofs. the connection never drops regardless of weather. 12. the reference design for the first ai satellites is built around nvidia rubin and GB300 chips. but the architecture is open. google TPUs, amazon trainium, any chip can go up. spacex is building the infrastructure, not locking in the compute. 13. spacex is the only operator on earth with experience running a constellation at the scale of 10,000 satellites. nobody else is even close. that operational knowledge is a moat that cannot be replicated quickly.
