High Altitude Elevator as a Tether for a Space Elevator

Physicists are trying to create a material that has a tensile strength great enough to create a cable to haul an object into space. The problem is, no material exists that is strong enough to support its own weight over such a great distance.

Here is the problem: Each length of cable must support the weight of all the length of cable below it. Scientists have been worrying over trying to create a cable array that can support its own weight as well as cargo over the entire distance.

My contribution: We need to support the weight of the cable in the lower 90kilometers of cable with high altitude balloons. At varying distances below that point (the 90km section), there will be a series of high altitude balloons supporting the cable.
