Overall, the surface of Earth receives about 89,000 terawatts, while the worldwide average power consumption rate was 15 terawatts in 2008. We receive approximately 5,933 times more energy from the sun at Earth’s surface than we currently consume globally.
(source : the sources cited at the bottom of http://en.wikipedia.org/wiki/World_energy_consumption)

What would $21 billion worth of solar panel installations on the roofs of Japanese factories, buildings, and houses output ? I can’t imagine there would be need for space based power generation after that.

I read Sunstroke and was impressed that David Kagan predicted that a space-based solar power station would be built and deployed by not only the US, but also by other nations, under the pretense of being a “purely alternative energy source to supply unlimited power to major cities”. Kagan spells out quite clearly that such space solar power stations employing high-intensity microwave beams could also be used as a devastating multi-pronged weapon: it can supply electricity to the military, be used to fry enemy ground troops, aircraft, ocean-going vessels, and also be used to disrupt enemy communications as well as destroy their agricultural capabilities. And the US EPA agrees.

LOL

Just think of all the sunny deserts we have. Not to mention wind and tidal power. Why not concentrate instead on developing space habitats and prepare for exodus? We shall prepare for a possible (and probable) future cataclysm, such as being hit by an asteroid. We shall also move human expansion into space to preserve Mother Earth as a museum for future generations; just as old downtowns in Europe are preserved and new development occurs in satellite communities.

If there are no cost overruns, and if that includes all costs!

Space solar sure isn’t cheap. Why doesn’t that surprise me?

Hopefully they can get the cost down a LOT in the future. They need a cheap way to put things in orbit.

Ah yes, the Microwave power plants. Those were fun.

Except when they misfired and caused total destruction… wait, that was funny too :P

No Ben, like Charles said, a 2×2 satellite would be very small. I think a postage stamp would be an overstatement. It would be more like a very large star or two put together.

No worry about shadow. Besides, light curves aroung objects.

It’s definitely gonna cost more than $21 billion in total.
