Eh, maybe we figure out a way to mimic one gigantic magnetic field with a sphere of small component fields. Maybe it’s a swarm of satellites each of which has its own little field and somehow they’re powering themselves with the momentum from the diverted solar wind. Like, the problem is too much kinetic energy input from the sun. And then the other problem is too little energy. All we gotta do is make sure the kinetic energy gets absorbed by the lithosphere, not the atmosphere. Ultimately that could be the swarm using gravity to transfer captured solar wind energy from orbit, through the atmosphere without interference, to the lithosphere.

Like, you know, people think of shit they didn’t think of before. Our engineering scales over time. It scales in scale. We’ll get it done.
