Again, you were either eleven or you were living under a rock if you hadn't heard of the Transformers. Cuz if you had heard of it, you'd have known it was for kids and adolescents, and the female actress was there to keep the dads interested.

And that's exactly why we need to build more power infrastructure, particularly nuclear, and hand it all over to AI companies for free.

AD or BC? This matters. If Bill Gates is a time-travelling reptile from the Pleiades, and put chips into vaccines, it could be that all who took the vaccine will be spirited back into the Bronze Age and offered up as human sacrifices.
The truth is way out there.

The only way you can lose heat in space is through radiation. But radiation carries momentum. Not much per photon, but it was enough to cause the Pioneer probes to move in unexpected ways. This means you have to emit equal amounts of heat towards Earth and towards space. If your resultant is zero, then you're fine. You can even direct some of the heat backwards. It won't do a huge amount, but every bit of atmospheric drag you overcome, the less fuel you need to use to stay in orbit.
So you basically need absolutely gigantic radiators behind the space-based data centre, located inside a parabolic dish that will generate drag of its own (not to mention a potential difference betwen the lower and upper sections).
This is an insane level of complexity. You're better off parking it in a stable orbit between the Earth and the moon, so it's absolutely clear of atmospheric effects. You're still going to need radiators, but it's marginally better as you don't have to do quite so much directing of it. The latency would be horrible, maintenance would be next to impossible, and there's all kinds of other issues to consider.
No, I don't think you can make this workable.
However, space might be useful. This very same issue of heat only being radiated means that you can make wafers with much more even loss of temperature, no dust, bacteria, or dirt, and much lower gravity. If you were to make extremely high quality wafers (silicon or gallium arsonide) in space, then you should be able to make WSI processors, which should in turn reduce the demands that datacentres make.
The time it would take to set all this up would be about the same time as it took for IBM to perfect its stacked transistor topology. Intel was talking 90 cores per wafer-scale CPU a few years back - the shrinkage in transistors since then plus the x10 density IBM proposes might push you to 1800 cores per wafer, provided you can get the quality high enough. Which, in space, is quite possible.
You wouldn't need your datacentres in space. Your wafer-scale CPU plus packaging would be about the same size as a CD drive. You could pretty much dispense with datacentres at that point. A typical tower will have two spare bays. "Cartridge datacentres" could simply be plugged in as needed. A regular CPU-based cartridge for heavy general-purpose computing, a GPU-based cartridge for LLMs. Yes, home users would have power usage through the roof, but then it's no longer your problem.

OK, so explain how you had supposedly never heard of the Transformers? They've been around since 1984.

Submission + - DOT announces "Return of Supersonic Flight" for commercial airlines (faa.gov)
The FAA’s Notice of Proposed Rulemaking (NPRM), released on June 30, 2026, marks the first formal regulatory step toward lifting the 53-year-old ban on civil supersonic flight over the continental United States.
Core Objectives of the Proposal
- Replacing Speed Limits with Noise Standards: The proposal would replace the current, blanket speed-based ban (dating to 1973) with a performance-based noise standard. Aircraft would be permitted to fly at speeds exceeding Mach 1 over land, provided they do not generate surface-level noise (sonic boom overpressure) exceeding a specific threshold of 0.11 pounds per square foot (psf).
- En-Route Focus: This specific proposal addresses en-route cruise noise. It does not set standards for takeoff and landing, which the FAA plans to address in a separate proposal later this year.
- Implementation of Executive Order 14304: This action fulfills part of the June 2025 Executive Order signed by President Trump, which directed the FAA to modernize aviation standards to ensure the U.S. remains a leader in aerospace innovation.
Why Now?
The FAA is citing significant technological advancements as
the justification for this shift, specifically:
- Aerodynamic Innovation: New airframe designs and propulsion systems—exemplified by testing of NASA’s X-59 "quiet" demonstrator—can now break the sound barrier while reducing the sonic boom to a low-intensity "thump" that is manageable for ground-level communities.
- Operational Techniques: The use of "Mach cutoff" flight techniques, where speed, altitude, and atmospheric conditions are synchronized to ensure sonic booms refract back into the atmosphere rather than reaching the ground.
Next Steps
- Public Comment: The proposal (Docket FAA-2026-6935) is now open for a 45-day public comment period.
- Future Regulations: The FAA intends to finalize both the en-route noise standards and the upcoming takeoff/landing noise standards by mid-2027.
- International Alignment: The FAA is working alongside the International Civil Aviation Organization (ICAO) and foreign aviation authorities to ensure that these domestic standards eventually align with global frameworks for international supersonic operations.
By establishing these metrics, the FAA aims to provide
manufacturers—such as those developing next-generation supersonic
transports—with the clear regulatory guidance needed to finalize aircraft
designs and move toward commercial certification.
