If science were to create an artificial magnetosphere to block solar winds, how much power would be required to generate the field?

OK, back of the napkin time: Let's say (from some oldish data from the late 1980s), that it needs to be strong enough to repel a solar storm with 5 x 10^17 joules, which is 5x10^17 watts/sec or 1.39x10^12 Wh or 139 billion kWh. And we'd need to sustain that for a few days, in the case of a solar storm, let's say we'd need about: 46 billion kWh of power a day for three days to repel a solar storm. Let's say our current electrical generation capabilities are about 20 trillion kWh a year, or about 54 billion kWh a day So, sure, theoretically, if scientists could build a planet-sized magnetic field generating device and plug all of the world's electrical plants into it, we'd be safe.

Of course, there' be no mahalo or refrigerators or even lights for the rest of us, but that would be a small sacrifice to avoid being fried in a solar storm (unless of course, we'd all get super powers from it).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
