>Solar Power Satellites have been a workable concept ... "It's raining soup out there. Time to invest in making some bowls. . . "

Remember that scene
in Young Frankenstein, when the
blind guy pours hot soup

in the monster's lap?
Wait until you feel the heat
from the microwave

transfer beams when they
go off target a little...
Whole cities could die...

Sorry, that was thought about and solved three decades ago.

The microwave beam suggested to beam the power has a peak power density sufficient to raise the temperature of a bird flying completely though the densest part of the beam by about .1 degree centigrade.

A rectenna complex for a SPS is approximately 10-15 kilometers is diameter (it would be oval, due to angular considerations: SPS would be in geosynchronous orbit over the Equator, and since the rectenna, at least in the US and Canada, would be in higher northern latitudes, simple geometry determines the shape. . .).

Besides, if you want to zap cities, just drop big rocks on them from orbit. . . .
