Given enough debris at different orbital heights, maybe Woz company can collect it at one location and use it as a launch platform, using the debris as the reaction-mass, then they can use solar power as the energy source to launch to higher orbits, rather than ejecting rocketfuel for thrust. Does this seem feasible? Given certain rocket trajectories, the debris could be made to fall back to earth, solving 2 problems at once - escape velocity energy needs as well as excessive space debris.

*Using space debris as railgun payload, but the railgun (rocket ship) is what you want to accelerate.
