Rumor has it that an experiment was tried with such a cable in space not 
as an elevator but as a massive current generator to power some kind of 
SDI device. Reportedly the cable broke and the experiment failed. Who 
knows if they tried it again. Maybe Sergio knows. He seems tuned into 
such things.
