Re: Space Elevators
The cost in rockets of putting the material up is massive. The cable materials have to be extended from the geosynchronous platform. Also we have no proven material for the cable.
The Space Elevator's ongoing maintenance is considerable too. A fusion / plasma torch rocket is frankly more believable than a space elevator on Earth.
An Elevator WILL work on the Moon.
Kevlar might actually be strong enough for a space elevator on Mars.
