Foolish man. It has nuclear in the title and is doomed to becoming a doomsday weapon that will end the world, not an efficient and cutting edge propulsion system.SPOOFE wrote:I think the OP misses the fact that most Space Elevator concepts are planned for decades from now, at the earliest.

I mean, really... $75,000 isn't going to build a new Saturn.
And if you REALLY want a feasible, cheap, and powerful heavy-lifting system, what about the old Omega nuclear-propulsion idea?
As for the space elevators, there's so many variations on the same theme, that it'll take a while just to see which is the cheapest and most practical. And that's forgetting the political and ecological issues that will rear their ugly heads.
