Evaporative cooling is the way it happens down on earth - and that shuttles h2o molecules from dense useful clumps like aquifers and rivers to a less useful form spread out in the air. But evaporating h2o isn’t an option in space afaik - since there’s a shortage of air to take up the h2o. In fact I think radiative cooling is the only actual option in space.
Fucking hell - do you all think ISS is cooled by hopes and prayers?
Starlink V3 sats have to dump ~20kW of pure waste heat just to exist. Going from that to the stated 100kW is an engineering task, not some sort of impossible arcane rite.
Looking forward to watching spacex defeat physics.
Starlink V3 bus already has to dispose of ~20kW of waste heat from the electronics - because RF amps aren't that great at what they do. That's a ~2020 server rack, in SPACE.
Going from that to a 2026 server rack is engineering, not magic.
