Technology@lemmy.world•SpaceX Stock Plunge Wipes Out $600 Billion After Cursor Deal Spooks InvestorsEnglish
6 daysMy favorite part about data centers in space is it may actually be impossible from a physics standpoint to build the heat radiators large enough for even a small one. Even though space is cold and would seem to make sense, it is also a destructive vacuum and to radiate even a small amount of heat outside of a shielded core would take a huge array of radiators

Asklemmy@lemmy.ml•According to Lemmy Users: Blockchain was a grift, AI is a grift, Quantum computing will be a future grift. So according to you what new and emergent technologies are not / will not be a grift?English
6 daysCalling blockchain a pure grift ignores the serious enterprise-level work being done to solve real logistical problems. The technology behind NFTs isn’t just for JPEGs it’s used to create a unique and immutable digital identity for stuff like physical shipping containers and pallets as digital twins. In a global supply chain where a single shipment passes through dozens of untrusted parties like factories, freight forwarders, ports, customs, and warehouses a distributed blockchain ledger provides a single source of truth that replaces manual emails, scanned paper documents, and spreadsheets. Smart contracts can automate releases upon verified scans, directly reducing the demurrage and detention fees that cost millions of dollars. The big hurdle isn’t that the tech doesn’t work or is a grift, it’s getting competing companies to agree on common standards and invest in the infrastructure. The speculation was a sideshow, but the underlying utility for tracking physical assets across trust boundaries is a real thing
Take that, China!

If you think that is because of Maduro and not decades of being illegally sanctioned and blockaded by their northern neighbor then I have a bridge to sell you.

These are rich upper class white skinned gusanos who are claiming Maduro is a dictator so they can have the US overthrow the government and resume their ownership class status. They want to privatize all the natural resources and live off the profit in Miami.













Yeah, maybe not impossible, but I mean extremely unlikely. I found a thread on reddit that had examples and a spreadsheet https://www.reddit.com/r/IsaacArthur/comments/11kp7s4/how_large_of_a_heatradiator_would_a_spacecraft/
To run a data center in space you would need some kind of reactor producing around 100 MW. If rejecting 100 MW at 800 K
A= 100,000,000 / 0.85×5.670374419e−8×800
The number is the Stefan-Boltzmann constant (σ) https://physics.knox.edu/OnlineHW/zTest-PhysicalConstants.html
A≈5,065 m²
So roughly:
5,100 m² of radiating surface
That is a square about:
√(5065) ≈71 m per side
If it is a double-sided radiator panel, the physical panel area could be about half:
2,530 m² of panel, about 50 m × 50 m, assuming both sides radiate effectively.
Also temperature matters enormously so
At emissivity 0.85:
So the answer is about 5,000 m² (lol this is like “a football field” on each side) at 800 K, but balloons to absurd levels like hundreds of thousands of m² if you are trying to dump room-temperature waste heat which there would be a significant amount of. That is for a single small data center at current power needs. In the US alone data centers use 176 TWh (https://www.congress.gov/crs-product/R48646), so there is no chance we are going to be migrating a significant portion of it into space.
