Cross "Solar Power Satellite" from your list.

It is economically absurd. It would cost more to put a single 1 Gwe SPS into operation that to build ALL of the powerplants in the World. Just look at dollar per kilogram costs for synchronous orbit. Then figure out how much the thing will weigh. Then forget it.
