A Plan to Stop Solar Storms From Sending Us Back to the Stone Age

[The Madcap]

4. Just find a nice cave, some flints, and an axe.

I think it's going to take more than six school bus-sized satellites to spread this stuff around the earth in an effective manner, given the altitude of 22000 miles.

The area of a sphere is 4 x pi x r^2. As the earth is roughly 7900 miles in diameter, the radius becomes 22000 + 7900 / 2 = 25950 miles. So the surface area of the covered area is approximately 4 x 3.141 x 25950 ^ 2 ~ 8,460,629,000 square miles. It had better be a very thin layer.

I can't imagine having enough control for the substance to spread evenly when originating from a half dozen satellites.
