two issues immediately come to my mind : 1. it will 'clean up' which is now-a-days an important thing 2. at the least it will give a lot of wieght in terms of...

... I think ground based lasers are a better scheme. Wait for the junk to fly overhead then ablate the side closest to you. That gives a push that changes the...
how about a space borne array of lasers? with precise posistioning a central computer can organize such an array to burn at will at anything in the space...

... I got a better idea: no. That's a weapon. Siteing a laser on the ground makes it impossible to fry cities with it. Besides, it's cheaper on the ground. -- ...
The roving spacecraft idea could only be practical if the space junk itself was used as propellant. Use a precision spring to kick the junk out of orbit, and...
this kind of maneuving is of limited application because the impluse provided, however bulky your spring may be, is very little, and the junk it can process...

You are right. However, if there is enough junk, it should be possible to always find a piece with an orbit sufficiently similar to the previous piece such...

... Actually, no. The minimum lunar elevator is just a few tonnes. That's sufficient to repeatedly soft-land hundreds of kilograms of equipment on the moon. ...
