In fairness, solar cells can be about 5x more efficient in space (irradiance, uptime).
The quoted "1 TW of photovoltaic cells per year, globally" is the peak output, not the average output. They're only about 20% higher peak output in space… well, if you can keep them cool at least.
The Goalpost shift continues, If elon were working for me, I would have fired him for having never delivered on any of his projects. Hyperloop > Neuralink > Self-Driving Cars > Robotaxi fleets > Personal Robots > Orbital Datacenters > [Insert next]
hmm Tesla shipped millions of cars SpaceX launches 90% of space payloads, Starlink is working well. Thats hard to categorize as never delivered on any of his projects
> it is possible to put 500 to 1000 TW/year of AI satellites into deep space, meaningfully ascend the Kardashev scale and harness a non-trivial percentage of the Sun’s power We currently make around 1 TW of photovoltaic cells per year, globally. The proposal here is to launch that much to space every 9 hours, complete with attached computers, continuously, from the moon. edit: Also, this would capture a very trivial…

From the Big Short (movie) Jared Vennett (narration): "In the years that followed, hundreds of bankers and rating agency's executives went to jail. The SEC was completely overhauled, and Congress had no choice but to break up the big banks and regulate the mortgage and derivatives industries." "Just kidding. Banks took the money the American people gave them, and they used it to pay themselves huge bonuses, and lobby…
If you had told me 4 years ago that Twitter would be merged into SpaceX I would have called you crazy. Yet here we are..
A former NASA engineer with a PhD in space electronics who later worked at Google for 10 years wrote an article about why datacenters in space are very technically challenging: https://taranis.ie/datacenters-in-space-are-a-terrible-horri... I don't have any specialized knowledge of the physics but I saw an article suggesting the real reason for the push to build them in space is to hedge against political pushback pr…
We don’t even have a habitable structure in space when the ISS falls, there is no world in which space datacenters are a thing in the next 10, I’d argue even 30 years. People really need to ground themselves in reality. Edit: okay Tiangong - but that is not a data center.

The crucial thing is that Tesla's valuation has the hype projects baked in. The fact that it never delivered self driving or a robotaxi fleet and is now being saved solely by an import ban on Chinese EVs means that any success he had with Tesla is now an illusion.
Once again pointing out Tesla has around 300 robotaxis running in 2 cities (Austin/SF).

put it back on the market for 1.5 trillion.
