You could throw a quarter out the window and see how far it lodged itself in the street.

That said quarter will never lodge itself anywhere because it will not fall as fast as you may think it would and combined with its negligible mass you could probably drop it on somebody's head and little will happen.

This isn't going to happen. At least not by the hands of this company.

Vagrant, your grasp of the physics and math here is atrocious. Go read the wiki article please, all the geeks and scientists who know calculus already figured out the math. It'll be educational and you'll have actual facts to base your opinion on instead of just a single poorly written news spot.

Hydrogen. LHe is inert. Rockets use LH2 for fuel and LOX for oxidizer.

I think a 400km very strong cable system would be easier than a 96,000km cable system that would only be slightly less as massive.

Yes, by being in geosynchronous orbit the cable isn't held taught by centrifugal force, which would be too much for the cable to bear. The counterweight would be orbiting in place without the need for a cable. So now you have a cable between two objects that are stationary relative to each other.

I'd pay good money just to get in one of those and cut the cheese.

It's about time. Rockets are just way too expensive. This''ll also open the door to larger craft, able to get us further than ever biggrin.gif

The logistics and materials necessary to build something long enough to wrap around the earth more than 2 times, the technology required to make it trong enough to withstand the extreme pressures exerted over something so huge extended that far into space, and the technology to even begin to figure out how to build it in the first place would seem to offset any savings we would incur by not having to use rockets.......
