Suppose the swarm parasol actually works, and you manage to bring the
average temperature on Venus down substantially. What would you do
about the day? Venus' "day" is 243 days, retrograde; and the orbital
period is about 225 days- one side will face the sun for over 100
days straight.

Simpler is better, less prone to fault.

We should leave the moon airless: more efficient solar power, better
telescope views. We buld skyscrapers on the earth, why
not "corescrapers" on the moon?
