Years ago when I first heard of the idea (beaming energy back to Earth from space) it made me wonder what would happen if such a device were to be hit by a bit of rock or space debris. If even for a split second the beam was knocked out of alignment, would it fry everything in its path? A 1-degree jitter from that distance would cover quite a lot of area on the ground.
Also, what about aero flight paths? Although, I suppose this could be a similar issue to the realization of a space elevator. You'd probably have to implement a no-fly zone to prevent serious damage.
