>Cooling will be a big issue

a 1m2 at 70C radiates 785 Watt. Seems thet cooling will be more simple than on Earth.

A 1m2 heatsink/fan on earth can sink kWs. My heatpump is about 1m2 area and can sink 15kw. Seems earth is at least 20x times better.

		If you build a pyramid with the base pointing to the sun (as solar), and a "height" about 5 times the base in constant shadow, with decent internal circulation, that will operate at sub-20C just from the two radiative sides pointing away from Earth (you make the earth pointing sides reflective) Cooling isn't an issue.

		in space 1m2 of thin metal will radiate those 785 watt. No fan, no heatpump, nothing. Only the launch cost. Which given the projected Starship launch cost will be cheaper than installation on Earth.
