Energy, heat and connectivity
Why the cold of space does not mean free cooling, where the real advantage of orbital energy lies, and what limits the connection to Earth imposes.

1. Why the cold of space does not mean free cooling
On Earth, a data center can reject heat using moving air, chilled water and cooling towers. All of that already exists around the installation and works continuously, but in space there is…
The real scale of radiators
In a 2 MW installation operating at reasonable temperatures, each square metre of radiator rejects only around 500 W. That requires deploying almost 4,000 m² of radiator surface, roughly…
Why in-orbit validation is still limited
What has been demonstrated well in orbit so far is still modest in scale: systems handling thousands of watts, not millions. That difference matters because moving from a powerful GPU or…
