Yeah, much easier to cool in space. ~1300 W/m^2 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/m^2, so you should expect them to have ~5 times the area of the radiator. Most of the mass of the satellite is solar panels.

Anybody want to see a tour of the inside of Aalo Atomics pilot factory? Had a full interview with them that went up a few days ago as well. @JoeTegtmeyer @TesLatino
This might be the fastest moving company in nuclear energy right now. @FutureAZA went inside the @AaloAtomics pilot factory, a 40,000 square foot space where small modular reactors are built in weeks, not years. The whole idea is to build nuclear reactors like products on an assembly line. The tour covers design for manufacturing, nuclear quality assurance, and how they built a reactor so fast. You also get a close look at the sodium steam generator, duplex tubes with micron sized gaps, and automated welding. Then there's the AI powered autonomous control, and a reactor designed to fit the footprint of a shipping container. If you care about abundant clean energy, this one is worth watching all the way to the criticality section. youtu.be/4lAxocs6ASo

So you want to send data wirelessly? Starlink does it. 5G (cellular) does it. Wi-Fi does it. What do they all have in common? QAM modulation. Data is just 1s and 0s. Eight bits make a byte. A byte can represent something as simple as a character or part of a pixel in a digital photograph. Put enough bytes together and you have sentences, images, video, and just about everything else we send digitally. But how does all of this travel "through the air"? Via radio signals, of course. More specifically, through a technique called Quadrature Amplitude Modulation (QAM). Here's how it works. The transceiver generates a radio wave whose amplitude and phase can be precisely controlled. Each unique combination represents a symbol. The receiver reads that symbol and translates it back into bits. This isn't unique to Starlink. 5G and Wi-Fi use the same basic technique, often employing higher-order modulation schemes such as 256-QAM or even 1024-QAM, depending on the technology and signal conditions. The key is signal quality. The higher the signal-to-noise ratio (SNR), the more reliably a receiver can distinguish between closely spaced symbols. That allows the system to use higher-order QAM, packing more bits into each symbol and increasing data throughput. Starlink does the same thing. It uses adaptive modulation, dynamically shifting between QAM schemes based on the quality of the connection. When SNR is high, it can use higher-order QAM and transmit more bits per symbol. When conditions deteriorate, it shifts to a more robust, lower-order scheme. Let's look specifically at 64-QAM. The "64" refers to the number of unique symbols, or states, that can be transmitted. QAM combines two carrier signals that are 90 degrees apart in phase (hence "quadrature"). By varying their amplitudes, the system creates 64 unique combinations. Since 64 = 2⁶, each symbol represents 6 bits of data. For example, the binary sequence 110011 maps to one specific point in the QAM constellation. A constellation diagram illustrates this nicely. It plots the 64 possible symbols in a two-dimensional space. Each point represents a unique combination of the two carrier signals, and therefore a unique 6-bit value. Now let's put some numbers around this. At a symbol rate of 90 million symbols per second, with 64-QAM carrying 6 bits per symbol, the theoretical data rate is: 90 million × 6 = 540 Mbps. That's before accounting for coding overhead and other protocol details. But there's another interesting aspect: the bandwidth is shared between transmitting and receiving data. In the example we're looking at, approximately 74 milliseconds of each second is allocated to uploading data from the subscriber terminal, while the remaining 926 milliseconds is allocated to downloading data from the satellite. In other words, the link is asymmetric, with considerably more capacity allocated to downloads than uploads.

Quality FSD behavior right here.
My Tesla saw the police's rear brake lights that flashed so my car assumed he had his lights on and slowed on a green then proceeded. Wondering what he was thinking?

Poteto just ABSOLUTELY COOKED Tibo. This rivalry is turning into actual cinema 😭 For anyone who missed the lore: - Tibo launched poteto.com, a simple finding game that redirects to ChatGPT. - Alex Wang responded with thibaultsottiaux.com, redirecting to Muse. - Now Poteto has fired back with tibo.dog, a whole survival game built in just 4 DAYS using Grok bot and Cursor. And the game is INSANE. You play as Tibo, fighting hordes of zombies (literally users begging for resets 💀), leveling up, surviving different stages, and facing a Muse-themed boss based on Alex Wang. - ~1,150 PRs in 4 days - Supports 10 languages - Custom engine, music, and pixel art - 500 enemies at 60 FPS - Just ~124 KB gzipped - Playable directly inside an X post - Easter eggs EVERYWHERE Poteto absolutely cooked with this one. I'm Team Poteto for this round. This rivalry has been way too entertaining LMAO. Who are you supporting: Tibo, Alex, or Poteto?
Day 28/ tibo's game has landed i spent $5.99 on this domain, but i had a blast making it with grok bot and cursor! i hope you enjoy it and find all the easter eggs 🤍 if i did it right you should be able to play it inside of X too tibo.dog

NEWS: Japan's MLIT to approve "steering-wheel-free" autonomous vehicles across the board from December. • Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) is considering blanket approval of driverless vehicles that have no steering wheel or brake pedal. • It plans to revise its vehicle safety standards and apply the new rules from December. • The aim is to support mass production, with the spread of robotaxis in mind. • The rules cover Level 4 vehicles, which drive fully autonomously under specific conditions, and Level 5 vehicles, which are fully autonomous everywhere. • Until now, each vehicle's safety has been certified case by case. • The plan will be discussed at the ministry's vehicle safety committee meeting on the 4th.

Grok Bot tip 💡 Got a task you repeat every day? Don't ask Grok Bot to do it from scratch each time! Ask it to write a Python script for it, then have a routine run that script. Same result, way less usage!

I think AI compute cost-per-watt prices are going to stay elevated a lot longer than many people expect. Less than 5% of U.S. consumers even pay a subscription for an AI product, with some putting the estimate <2%. People are clearly finding Grok Bot to be very useful because @SpaceX just had to significantly cut back usage capacity due to overwhelming demand. But we're still so early in the AI adoption curve. Existing users are going to eat up significantly more compute as models get better and agents start handling increasingly complex tasks and jobs. Inference will increasingly become a larger and larger share of compute capacity. People are seriously underestimating how much demand is still ahead of us and how long it'll take supply to catch up. I think this is partly why Elon thinks SpaceX could exit 2027 with an annual recurring revenue rate of $500 billion to $1 trillion. They can deploy the compute faster than anyone else, and the demand for that compute is insatiable, and likely will be for a long time to come.

Vermilion Parish has 5,139 oil and gas wells. Only 109 are still producing. Everyone talks about what Starbase Louisiana might bring to our parish, but fewer people talk about what we've already lost. When I was growing up, oil and gas in the south end of Vermilion Parish helped pay for a lot of things here at home. It also put food on the table for most of the families I knew, including mine. My mom and dad both worked jobs tied to the oilfield, and my own work is still tied to it today. I wanted to see what those numbers look like now, so I decided to do some research. I began with the parish as a whole. The state collects a severance tax on oil and gas pulled out of the ground. In fiscal year 2018-19, the state collected $19.1 million in severance tax on oil and gas produced in Vermilion Parish. In fiscal year 2025-26, it was about $10.3 million. That is down about 46 percent in seven years, according to Louisiana Department of Revenue reports. I also looked at our schools. Much of the Vermilion Parish School Board's oil and gas money came from leases and royalties on its Section 16 land, which is land set aside to support our schools. A lot of it sits in the south end of the parish. In 2014, the School Board collected over $6 million in oil and gas revenue. In the 2024-25 school year, it collected about $150,000. That is a drop of roughly 97 percent. As far back as 2021, the local paper reported there was no drilling on that land and the district was losing millions. The money swings so much that board policy keeps it out of the general fund. Then there is the Police Jury, which runs parish government. Its severance tax money actually went up, from about $1 million in 2017 to about $1.24 million in 2023. The reason is in the state constitution. A parish gets one-fifth of the severance tax collected on its production, but only up to a cap. That cap was $850,000 in 2007 and rises with inflation each year. It was about $1.33 million in 2024-25. One-fifth of what Vermilion produces is well above that cap, so the Police Jury's share is held down by the cap, not by how much we produce. It's a small, steady slice of the money that comes out of our ground. Most of the rest goes to the state. Even the Sheriff's Office feels the shift. It doesn't get oil and gas royalties, but wells here are taxed as property, and they have lost a lot of value. In 2015, the parish's 604 taxable wells were assessed at about $42.3 million. By 2023, 555 wells were assessed at about $22.7 million. Oil and gas wells went from about 9 percent of the parish's assessed value in 2015 to about 5 percent in 2023. Homes and other property now carry a bigger share of the load for local services. You can see it on the map. Most of those wells are now plugged, dry, or idle. That is the bigger picture behind a lot of the conversations happening in our parish right now. The income our parish leaned on for decades has gotten smaller and less predictable. New industry, including Starbase Louisiana, could help fill some of that gap over time. But the slide in oil and gas money is a story of its own, and it is worth knowing. Thank you to @LAGovJeffLandry and Louisiana Economic Development for working to bring new opportunity to the south end of our parish. Places like ours have given a lot to this state, and it means something to see someone invest back in it.

Elon resurrects Spam. Hormel was destined to be remembered for unwanted emails and text messages. But apparently, Spam means something entirely different now. It's the name of a data center within the Colossus complex. And the building? It was once a warehouse for Hormel products. Now it will house ~200,000 GB300s. Talk about a rebranding.
Macroharder and Minihard both have 220k GB300s with 800 gig nics configured for training. Gun Range will have the same. Spam (used to house Hormel products) will have ~200k GB300s, but configured for inference, so much simpler networking and less than half the fiber. I walked the whole Colossus 2 site around midnight and again this morning. Good progress by the SpaceX team and contractors. Gun Range is tracking to be operational by end of November and Spam in December.
