Everyone has heard of the space elevator using a cable(s) that attaches to a geosynchronus satellite. Now trying to lift things is always a very energy expensive process, since just making a payload weightless cost energy and you get zero velocity and travel. Also how fast could an elevator travel using friction to move up the cable? An elevator moving 200 mph would take five days or more to get to orbit! What if the cable positioned wasn't striaght up? What if the cable actually ran accross the earth to the horizon striaght to the satellite? When the cable is actually horizontal then you're only having to push mass. Obviously as the cable rises because of the earth's curvature the angle with respect to the ground increases and there is some gravity that must be overcome but its still a lot less effort when compared to moving striaght up. If the cable could be magnitized then the space train could use a solinoid principle for propulsion and actually move at supersonic speeds since there is no contact with the cable the travel is fictionless across the cable! My first question is would the cable droop? My impression is perhaps not since the tension from the attached satellite should hold the cable taught.
