ELON MUSK PREDICTS SPACE WILL BE THE CHEAPEST PLACE TO RUN AI INFERENCE “I think the case is a no-brainer for building solar-powered AI data centers in space” In space, you get unlimited solar power with panels facing the sun In the shadow, it’s freezing cold - just 3... Kelvin - giving you an incredibly efficient natural cooling system with a radiator pointed away from the sunshow more

He's also discussed the use of satellites to 'beam' that solar energy down to the Earth in a much more efficient and multiplied way. Within a generation, we very well could be running all of our country's energy and electrical needs from satellites 'beaming down' intense levels of solar energy to collection points on the surface.

@elonmusk Space is the future.

@elonmusk And the space data centers don’t use water a critical resource for humanity

Space data centers will be the cheapest

@elonmusk Plus the little aliens will work for free. Bonus 👽

@elonmusk Musk at WEF with Fink: space AI farms, endless sun, 3K cooling for free. No-brainer if you're dodging Earth's blackouts and regs. Ties right to his lunar mass drivers for 1000GW compute, xAI off-planet before regulators blink. Gates' bunkers got nothing on orbital overlords.

Unlimited solar power. Natural cooling at 3 Kelvin. Sounds futuristic. But let’s talk reality. Launching hardware to space is still insanely expensive. Maintenance? Near impossible. Upgrades? Complicated. Cosmic radiation? A real threat to chips. Earth already has deserts for solar. Oceans for cooling. And infrastructure that doesn’t require rockets. Before moving AI to orbit, maybe we should fix energy grids on Earth. Space isn’t automatically cheaper. It’s just further away. Innovation is powerful. But physics, logistics, and economics still vote.

@elonmusk Let’s get less retarded and play some video games @elonmusk ?

@elonmusk Or RENT IT from the Pi Network: @PiCoreTeam 🤝 The AI & DePIN Revolution (Mind-Blowing!): How Pi’s 410,000 nodes and 17.7M KYC-verified humans are the exact infrastructure trillion-dollar AI companies desperately need. 🤖

This might work!

@elonmusk AI in space? Only Elon would make cooling and solar power sound like a master plan.

How it started: 'Our data center is underwater for cooling.' 🌊 How it's going: 'Our AI is currently orbiting Mars to save on the electricity bill.' 🤡🛰️ Tim Cook is worried about 15% tariffs, while Elon is just moving the entire supply chain to zero-G. Level 99 efficiency.

@elonmusk He will do it

@elonmusk We’re literally moving from 'The Cloud' to 'The Cosmos.' Solving the two biggest scaling bottlenecks energy and heat...by simply leaving the atmosphere is the ultimate engineering flex. Earth for training, the Heavens for inference....

Space-based AI inference is such a clean physics win: unlimited solar 24/7 + free 3 Kelvin cooling in the shade. No Earth constraints at all. Starship is the unlock — when heavy lift becomes truly cheap, orbital clusters become the default for massive-scale Grok inference. xAI + SpaceX executing this vision is going to be unstoppable. The cheapest intelligence in the solar system is coming.

@elonmusk We will need unlimited solar power for all the robots. Let's go and get the solar energy in space!

Over 20 years on.. And here on Earth we have people who think they're furry animals, men in dresses randomly killing people, a religion stuck in the Dark Ages trying to take over the world, Hollywood celebrities preaching morals to us, while practicing Satanism.. & The Kardashians ! Quick- Beam us up, Elon !!

Absolutely agree unlimited solar + near-zero-K cooling in orbit is a game-changer for AI costs. Starship makes it feasible soon. Earth data centers can't compete long-term

Unlimited solar & 3K cooling sound epic until you add $100–500/kg launch costs, rad-hardening penalties, and massive radiative panels needed in vacuum (no convection!). 'Free' cooling becomes the priciest part. Physics says not a no-brainer yet.

@elonmusk To the space we go $melon musk

@elonmusk Exactly

Elon Musk is a rare human being, super smart and has contributed a lot to the good of the earth.

@elonmusk Seems like radiation will be a big hurdle for these data centers

@elonmusk Now this is something unreal, but the fact remains that it is real.

Exactly 👍

Why does Elon keep shilling this account? Is it run by his cousin or something?

Unlimited solar power: In space, solar panels can capture sunlight almost 24/7 without atmospheric loss, meaning theoretically near-free energy compared to Earth-based data centers where electricity is a major cost. This is especially attractive for AI, which is extremely energy-hungry. Extreme cooling advantage: Heat is the enemy of computation. In space, the shadowed areas are near absolute zero (~3 Kelvin). Radiators facing away from the sun could potentially reject heat extremely efficiently. On Earth, cooling servers consumes a significant fraction of operational costs. Space could almost eliminate that. Scalability: If you have a modular, orbiting AI data center, you can potentially scale massively without worrying about land, local energy limits, or environmental constraints. Major challenges: Launch costs: Even with SpaceX’s Starship ambitions to reduce cost per kilogram to orbit, sending thousands of tons of AI hardware into space is currently astronomically expensive. Until launch costs drop dramatically, it’s hard to imagine this being economically feasible. Maintenance and repairs: Hardware in space is exposed to radiation, micro-meteoroids, and cosmic rays. Servicing servers is far more complicated and expensive than swapping a faulty component on Earth. Even with autonomous robots, redundancy and durability would be major design hurdles. Latency and connectivity: AI inference often requires fast communication with users or other systems. Orbiting data centers will face unavoidable communication delays, especially for Earth-based applications. For some AI tasks (like local cloud inference), this could be a dealbreaker. Engineering complexity: Power storage, radiation shielding, thermal management

@elonmusk 😁

I cant wait to see him make this dream come true as well, he is such a genius

Space isn't just a destination; it’s the ultimate thermal solution. 3 Kelvin of natural cooling and infinite solar power to scale AI where Earth no longer can. 🛰️❄️ Computational sovereignty will be orbital, or it won't be at all.

@elonmusk Yes

That is a pretty simplistic way to look at it. There is more to radiative cooling such as Earth albedo, solar panel heating due to inefficiency. The loss of two cooling methods (conductive can be made to work) introduces thermal load transfer issues. Not now, but maybe later.

Cheap AI? The hot ticket! Unlimited solar, free cooling, Starship unlocks it. Who's hyped? #MAGA🦅🇺🇸
