What a clever trick to throw more money (governmental subsidies) into a sinking ship (xAI and "AI" in general). Perplexingly this maneuver will probably boost stock prices thus creating more monopoly money to burn resources with.

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…

It's much easier to find a country or jurisdiction that doesn't care about a bunch of data centers vs launching them into space. I don't get why we aren't building mixed use buildings, maybe the first floor can be retail and restaurants, the next two floors can be data centers, and then above that apartments.

In Switzerland infomaniak built a data center under apartments and DC heat is used for heating. There are some videos about it.

Those interesting things won't pump up the perceived value of Musk companies to stratospheric levels - or dare I say - to the moon. He needs the public to believe that to earn the trillion-dollar package from the Tesla-Twitter-SpaceX conglomerate, even if the latter turns out to be the only profitable arm of the conglomerate.

Photovoltaic production has been doubling every year. That's not a huge amount of doubling!

> 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 It's curious that we live in a world in which I think the majority of people somehow think this ISN'T complicated. Like, have we long since reached the point where technology is suitably advanced to average people that it seems like magic, wh…

you can’t tell me the microwave isn’t magic. it’s magic.

I can put things in a box that uses spooky electromagnetic waves to tickle water molecules to the point that they get hot and maybe boil off, given the chance? Sounds like magic to me

Americans have trouble understanding something like that. We believe anything short of a 3bdrm house with a lawn and backyard is communism.

I'd love to live in a dense city. My office within waking distance. A Cafe in my apartment building, etc.

Hey now. Huperliop was designed to scuttle California’s light rail project. Which it did. Mission accomplished.

Still failed and missed every projection. I think he said we would be on Mars too?

You're not considering some important multipliers. In space you're already getting a substantial immediate boost due to greater solar irradiance - no atmosphere or anything getting in the way of those juicy photons. You can also get 24 hour coverage in space. And finally they mention "deep space" - it's unclear what that means but solar irradiance increases on an inverse square law - get half way to the sun and you're getting another 4x boost in power. I'm sure there's other factors I'm not considering as well - space and solar just go quite well together.
