I actually agree(d) with that reasoning, I also initially assumed random placement. Others on this page suggested them being steerable. But we're both very wrong- I read the whole paper. Some aspects are well thought out and highly technical, while others are glossed over as requirements tbd. Briefly: He does intend to steer/ orient the discs using radiative pressure from a network of control satellites and gps-like navigation "beacons", but overlap is also required to take into account the required oblique angles and transparency of the discs. I'm left being very impressed with the provided technical details of the disk constellation, but even more skeptical overall, mostly due to lack of detail on some major supporting elements. He offers no detail of the required deployment method, or even the scope of the required navigation and control network. He also states each disk will require a gps-like receiver, 2 cameras, some power and processing capability, and a method of communicating with said networks, all while still assuming 1g per disc and no added cost... It's not conceptual level, so much as it's conceptual for maybe one out of dozens of required massively scaled elements. Also, it addresses no risk management / mitigation concerns.
