!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

Unless I missed something, all of his math assumes 20kW of computers, that's not even one rack for heavy stuff, of course you can run a data center in space if you send one satellite up for each computer, that's just unpractical.
Let me put this into perspective, what you're saying is like someone has an idea for a revolutionary parking plaza, and they're showing you it's feasible to spend millions of dollars to park one motorcycle in it.
The actual Starmind satellites will have 175kW of compute on them, Scott made that video before the specs were released so he assumed a minimum package. But all of this scales linearly, if you double the power usage you just double the size of the solar panels and double the size of the radiators. If a 20kW satellite works then you can bolt ten of them together and get a 200kW satellite that works too.
Cool, so we moved from a single motorcycle to a couple of cars, still a long way from a parking lot. You're not understanding the issue, the scale is not feasible, you'll spend millions of dollars to launch a single satellite that's not even 1/10th of a tiny data center.
They're not putting up just one satellite. It's going to be a constellation. The constellation as a whole will be equivalent to a data center.
Also, it won't cost them millions of dollars to launch a single satellite. That's why this project is paired up with Starship development, the two go hand in hand. Starship makes the launches cheap, Starmind gives Starship the scale of demand a ship like that needs for its economics to work.
Even by their own estimates it's 2-10 million dollars per launch, imagine thinking that spending 6 million dollars to get a single rack in space where it can't be maintained and will become garbage in a couple of years is a good investment. And that's just the launch price, you still need to build the satellite, with its hundreds of square meters of solar panels and radiators. There's no point arguing this any more than there was a point arguing hyperloop, until they present a feasible product it's just big talk.
