I read recently, though it is not an old topic in science circles, of scientists and private investors planning on making a functioning space elevator to replace the fule powerd rockets to reach our atmosphere. Would the space elevator be a good application to replace the space shuttles since NASA wants to retire the space shuttles, or are the scientists and private investors barking up the wrong carbon nanotube?

This idea cannot replace the shuttle, though it is what we should be investing in for the future. The technology is not near ready yet. I am not just speaking of the carbon nanotubes. There are other problems to solve such as protecting the climber from radiation and protecting the nanotubes from tiny particle sized meteorites.

I think we are best looking elsewhere. I think we would be better of inventing a craft which can fly us easier and safer to the space station and behond. Even though i'm not remotly close to being a astronomist the idea of an elavator directly to the space stations seems like a waster of money and intelectual brain power.

the space elevator concept is quite viable and nearly within current technical bounds. Essentially you need a very strong and very light monofilament cable and a lift station in a geosynchronous orbit.

The costs of setting this up are pretty astronomical though and we haven't quite got the cable required, but once set up, the energy required to get equipment into orbit is minimal compared to a rocket launch and in the long run it's the practical way to move industry into orbit in a large scale or form the bridgehead to build spaceships in orbit for cheaper exploration of more distant space.

Was it on this forum I first heard about the Aerovator?

It sounds like an interesting idea, anyway, and has some pretty big advantages over the space elevator.

Personally, I love the idea of a cable reaching up into space. Sounds like the sort of thing I want to see photos of.

Zwilnik just likes the idea because he expects to play Airburst up there [Smile]

I think as with most things the right people need to put their money in the right place. I can see this happening more readily than anything useful being done with the shuttle (other than joy rides, if you count that as useful).
