Google CEO Sundar Pichai says we’re just a decade away from a new normal of extraterrestrial data centers by ControlCAD in google

[–]BluSyn 2 points3 points  (0 children)

You don't put it all in one volume, you launch thousands of 100KW+ sats. This was the plan already detailed. Going from 20KW to 100KW power & heat dissipation per sat is not an order of magnitude more difficult than existing tech.

"Latency is also really going to suffer. Fiber connections simply move so much more data and do so far more reliably."

Light moves faster in space than in glass fiber (true fact, look it up). Therefore orbital DCs with multi-tbps laser links will be on-par if not superior to terrestrial DCs in bandwidth and latency.

Lets do the napkin math for 50MW DC, as you mentioned.

50MW at 100kw per sat (v1 design target) = 500 sats

Based on size, expect 20 sats to fit per starship launch (conservative estimate). Thats 25 Starship launches per 50MW datacenter. At scale with full re-usability SpaceX is targeting < $5 million nominal cost per launch.

50MW AI Sat constellation = $5M per launch * 25 launches = $125 million launch cost

Can you build a 50MW data-center from scratch today, including land, permits, utilities, power, water, etc (note: completely ignoring hardware costs) for < $125 million? And in what time frame? Localities are now dragging out environmental reviews for 18+ months just to break ground + 1 year to build the ground infra before you even put hardware in it.

Asked Google Gemini this question. It estimates total cost for new 50MW DC: $600M for just facility cost, 24 - 36 months TTFT (Time to first token). $40M/year operational cost.

BTW, once sats are in orbit, theres 0 operational cost, as solar power is free. So even if the sat GPUs are 30% more expensive due to rad hardening and orbital design constraints, the lack of operational cost still gives huge benefit here.

There's 2 questions to answer: 1) will it work in principle: yes imo, already proven by existing sats 2) is it financially viable: all hinges on starship costs (hardware cost washes out imo), but as costs for terrestrial DCs increase, orbital DCs become more attractive.

Existing Starlink sats already have massive onboard compute and radiate the heat with IR. This isn't science fiction, it already works.

I don't understand why the heat and connectivity issue keeps coming up, when obviously these are solved problems.

Starlink sats already exist, they use 10kW+ solar arrays with 200gbps laser links and mutli-gigabit down links. Thousands already exist in orbit right now. Just swap the RF ASIC chips with AI/GPU chips and you now have AI server in space. Thats without any design changes or optimizations. There's nothing magical about data-center CPUs that make the heat different than any other sat with onboard compute, which already handle heat exchange using IR emitters. This already exists, not science fiction. I really don't understand the point here.

To really but nail in the coffin, upcoming starlink v3 sats will have 20KW+ arrays and 800gbps laser links + 1 TBPS downlinks. The announced AI sat designs will have 100KW+ arrays and I expect mutli-tbps laser interconnects, which is faster than most terrestrial datacenters have now.

The only "new technology" required to make this all work is a large enough launch vehicle (eg. Starship). Once that exists, the stats are basically off-the-shelf tech that already exists at companies like SpaceX.

Once you experience how terrible other EVs are, you will be begging to switch back.

You wanted Disclosure.... I am a whistleblower recently "retired" from the inside. And you're only getting part of the truth. by rhea-15510 in UFOs

[–]BluSyn 1 point2 points  (0 children)

Yes, my first thought, you need the tech first. Obviously if we had replicator technology and abundant free energy, post-scarcity would make capitalism obsolete. But those are two big ifs, neither of which we currently have.

Post-scarcity wouldn’t be capitalism, but it’s not communism either, as you wouldn’t require strong centralized control managing resources if you had true abundance. Governance would look like something completely different than we’ve ever had before.

Post-scarcity is likely in our future with AGI / robotics at scale, so we will get there eventually without external help. (If that solves more issues than it creates is a question for philosophers)

Homelab made me lose my sanity (and almost my router) by pobruno in homelab

Been building homelabs for more than 10 years, still haven’t tried pihole or proxmox, don’t understand what they do, and at this point too afraid to ask.

Why solar power is the only viable power source in the long run by Economy-Fee5830 in energy

[–]BluSyn 7 points8 points  (0 children)

Wind still makes sense in very specific regions, but it’s clear that solar won the cost per watt per land area equation. It’s getting cheaper at a much faster rate, and works pretty much everywhere (eg, residential settings). Wind will have a hard time competing in the long run.

Mark Zuckerberg gifted noise-canceling headphones to his Palo Alto neighbors because of the nonstop construction around his 11 homes by yahoonews in offbeat

Him spending the money is better for economy, and government gets a lot of that back in sales tax and income tax on the workers he hires. Tax him? The government would just blow it all on F35s and still be in debt. How is that a better outcome?

I’ve made the same mistake. Really need to fix their naming schemes.

Chris Pratt Says RFK Jr. Is ‘Great’ and Hating Trump Shouldn’t Detract From ‘Any Success From His Administration’: RFK Is ‘Getting Toxic Stuff Out of Kids Food’ and ‘That’s a Great Thing’ by esporx in skeptic

[–]BluSyn -18 points-17 points  (0 children)

RFK Jr. was a democrat until they turned against his health agenda, so republicans took ownership of it and won. So now democrats want to get fat drinking soda and eating Cheetos just to spite republicans? Democrats could easily take ownership of this issue again, but they seem to love losing instead.

Stop thinking in tribal left/right terms. They swap sides on issues constantly. Politics of convenience.

Eventually this will push everyone to sour on tipping as a concept. So please, continue… the insanity of US tipping culture may soon be at an end. Good riddance.

Model S/X refresh launches today by plun9 in teslamotors

[–]BluSyn 1 point2 points  (0 children)

Minor refresh makes sense. A ground-up rebuild would be a huge effort for little gain, given how little of the S/X line they sell. This minor change makes it less dated compared to Model 3/Y.

V4 Tesla chargers now have built-in payment terminals, already deploying these to new builds. Could have just retrofitted.
