Reply to comment by holmgangCore in Would building a Dyson sphere be worth it: We ran the numbers. by filosoful

If made of individual drones rather than a solid shell, the drones could attempt to evade? Might not get out of the way successfully often, but maybe a little. I don't know the scale and speed of such events to know if evasion is possible. Maybe I'm talking about trying to dodge a bullet.

So a serious CME could hit Earth in 20 hours. 1 AU in 20 hours. That’s ~4.6 million mph and literally billions of tons of charged particles.

Anton Petrov had a recent episode on the CME of March 13th with some video from the SDO that might give you some sense of scale & speed.

How close would these drones be to the Sun? 1/2 AU? 1/4 AU?
