      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:

      Radiator temp Area for 100 MW
      300 K ~256,000 m²
      500 K ~33,200 m²
      800 K ~5,100 m²

      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.

        My 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

          Calling 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

                                  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.
