Whilst I agree that this glosses over a huge number of technical obstacles, space based solar power could scale more easily than that on earth. Lack of variable weather and gravity means rather than using photovoltaic cells, you can just set up paper thin huge mirrors to focus light and generate steam.

Caveat: my understanding of this largely comes from the book The High Frontier, which is really old and probably inaccurate. I can't think of a reason why this particular point would be wrong though.
