I've thought for quite a while that one approach might be to find
(perhaps in NASA's archives) a product that requires 0/micro gravity to
be produced and attempt to capitalize on that as a means of jump-starting a private space effort.
Another possibility might be to devise a _cheap_ way of accessing asteroid resources.
i.e.: solar sail probes to locate promising bodies and light weight
(mylar?) mirrors combined with solar powered MHD separators and either
rail gun or sail return of refined materials to LEO. Regardless of progress in other field we _must_ have a way off this mud ball!
BTW, I've heard that NASA has a fairly complete project worked out for a
Lunar processing facility. Does anyone know anything about this or is it just another rumor?
