It does seem kind of resource-wasting to use lots of fuel to transport materials from existing foundations to build an artificial planet, instead of just building on an existing one. If we had some sort of nuclear engine, or dilithium crystals or something, then it might make sense, but as long as propulsion requires vast amounts of rocket fuel, moving mass is not a good solution. And yes, rocket fuel can be produced on the moon etc, but that requires vast solar arrays and refining stations to be launched, and the cost just increases exponentially.

Nascar during a caution lol

@danm4320 since these have to constantly face the earth, the orientation can't be changed, so angles of reflection will occur. The problem with coating them in Vantablack or something totally non reflective is that they would absorb much more heat from the constant sun exposure, and overheat. So some balance of heat rejecting, and diffusion to reduce direct reflection is needed.

Part of the reflectivity issue is heat abortion. If you make them Vantablack, it will overheat from constant sun exposure. Some sort of diffusive coating is what's needed, to reduce reflection while dispersing energy.
