@patrickc@bchesky can we not do this please. no matter what you rich guys do, they will still steal and complain about taxes. it will never fix the commie problem.
@nicbarkeragain How are living in a different world? At what point do you travel to the reality?!! I confused. I hope there is still market for man-made code.
He has. Multiple times on X, podcasts and interviews…
The core physics he stresses is radiative cooling into the ~3 K cosmic background via the Stefan-Boltzmann law, aluminum radiators oriented away from the Sun, higher operating temperatures reducing radiator area, solar panels at ~250 W/m² needing ~5× the radiator area, and the fact that once mass-to-orbit is cheap (Starship), the system is simpler/passive compared with terrestrial liquid cooling + chillers.
November 3, 2026 – Primary numbers post “Yeah, much easier to cool in space. ~1300 W/m² is easily achievable for an aluminum radiator pointed away from the Sun, as it is mostly just seeing cosmic background radiation at ~3 degrees above absolute zero! Solar panels generate ~250 W/m², so you should expect them to have ~5 times the area of the radiator. Most of the mass of the satellite is solar panels.” Link: A direct reply to Shaun Maguire’s detailed technical post (aluminum structure + ammonia phase-change loop, passive circulation, (T^4) advantage). Full thread starts around Maguire’s post: https://t.co/Krt8LDE0aD.
November 3, 2026 – Follow-up reply on scaling “Yup, T^4 scales super fast.” Link: https://t.co/bAVr1q3glT (Responding to discussion of how sharply radiation rises with temperature.)
October 24, 2025 – (T^4) and Kardashev scale “Radiative cooling rising as (T^4) really favors higher operating temperatures. Ultimately, solar-powered AI satellites are the only way to achieve a Kardashev-II civilization.” Link: https://t.co/e7nKtmH4nr
August 31, 2026 – Critique of critics “When someone who claims they’re super smart says that orbital AI is impossible due to cooling or whatever, but doesn’t even know things as basic as heat rejection of the radiator per m², coolant temp or max operating temp of the GPU 🤦♂️” Link: https://t.co/lcRHdPIdZB
January 20, 2026 – Higher GPU temperature advantage “Within a few iterations, we can probably get AI satellites to <100 kW/ton, inclusive of all components, especially if the GPU is designed to operate at ~370 Kelvin.” Link: https://t.co/7E1DpRli7C
SpaceX AI1 / Starmind design references (publicly discussed around June 2026): ~110 m² deployable liquid radiators, ~1,400 W/m² (both sides, knife-edge to Sun), 120 kW sustained / 150 kW peak, solar ~250 W/m². Elon has referenced these numbers in the context of the posts above.
Podcasts & Interviews
•Dwarkesh Patel podcast (with John Collison), February 5, 2026 Elon discusses continuous solar (always sunny, ~5× effectiveness, no batteries), radiative cooling advantages, designing chips to run hotter to cut radiator mass, radiation resilience of neural nets, and overall orbital economics. YouTube: https://t.co/UZECfm2pDc
•U.S.-Saudi Investment Forum / related appearances (around November 2025) – Explicit remarks that “the cooling is just radiative,” solar panels are cheaper without glass/framing, continuous solar. Often paired with Jensen Huang noting that terrestrial racks are mostly cooling mass.
•Other interviews / conferences (2025–2026) – Repeated points on radiative cooling being simpler once mass-to-orbit is cheap, higher operating temperatures helping via (T^4), and Starship as the enabler.
@broudsov@elonmusk Youtube can a place for entertainment and educational but be aware of whom you listen to. There is no shortage of arm chair "pick a topic".
@matthewstoller@bscholl You are using too many words for such a simple thought. Let me help you. Say it like this, and people will understand much quicker: "I want to seize someone's assets because I am a commie."
Scott Galloway wants Elon Musk executed. Kara Swisher wants Big Balls imprisoned.
The left hates men who embody the “great man” archetype and wants to make an example of them.
@scrowder Do you own one? Don't get me wrong, the liberals hate cybertruck because elon sided with trump but I don't recall seeing a lot of conservatives driving and supporting. Its a victim of politics.
@TaylorLorenz The problem is, they haven't been antagonist enough to fight socialism/communism. Atleast elon is fighting the good fight with the fear of backlash.
