Heat is radiated into the vacuum for free

When you combine that with a mesh network like Starlink, the need for laying fiber lines disappears entirely

Citation needed.

And on water usage, I will point out that gas generators and evaporative cooling are only used on Earth because other methods (geothermal, big radiators, heatpumps) are somewhat more expensive… Not, like, orders of magnitude more expensive like pure radiative cooling in space.
