I've got a piece up at The Space Review: "How to energize the space economy." It involves space solar power and space property rights, and related topics.
UPDATE 5/7: A lot of interesting comments at my post, and I got some positive feedback privately from someone experienced in moving stuff around in space. The Space Review has a readership that's very focused on space policy, a subject that doesn't get its due in the media world at large. I'll write for the site again sooner or later. Meanwhile, posting may be light here at Quicksilber in the near term.
UPDATE 5/7: Flashback to 2003: "Choices in Space." This piece is dated but still has some relevance in summarizing different viewpoints as to what to do (and not do) in space. I'm less of a Humans to Mars (anytime soon) believer than I was then, though.
UPDATE: Someone likes this in Portugal.
