Let's say the cable gets detached really close to the geosynchronous tether point (that's the worst case, right?). How much of the cable will burn up in the atmosphere? What is the density of the carbon nano-tube / graphene ribbons? And what is their terminal velocity? Has anyone proposed dimension of a graphene ribbon tether? Like it is 300 mm wide by 0.01 mm thick?
