I love the concept of colonizing Venus. Thanks for bringing up some new points I hadn’t considered before! Something to note, however, is that because of Venus’ slow rotation, it too has no magnetic field. From this respect, though the solar power potential is 4x that of Mars, the radiation intensity is also 4x that of Mars as well. Going deeper into the atmosphere can counteract some of this, but this also lowers your solar power potential as well. Thanks for this thought provoking article!
