Space-based reflectors on the scale of 600,000 square miles could cost about $800B if we could get transport costs down to $50/kg, it'd cost about $400 Trillion

Space-based reflectors on the scale of 600,000 square miles could cost about $800B if we could get transport costs down to $50/kg, it'd cost about $400 Trillion at the current cost.
