<...Now visualize a future billionaire enthusiast infected by the space bug. It is possible that someday, someone writes the check. It gets easier to do technologically each decade.
We spent a lot of years trying to find such an "angel." It's harder than you might think. There are a few: Walt Anderson invested heavily in our Roton project, and in the attempt to commercialize Mir. Andy Beal made a start with his rocket project, but for his own reasons, gave up before he finished. Bigelow is working on space station ideas.
More may follow as the technology improves.
