I kind of like this concept. You'd need some type of receiver as well, obviously, and the real issue would be lining up the beam. What if the projector was on a turret and could "lock on" to the nearest receiver within range? I'd say the max range would be about 30% of the farthest distance at which techs are normally active. In co-op it would probably be anywhere within the red ring. Then you could just attach more projector turrets to techs and create a relay system. Here's the big problem, though: right now only the part of the world that's relatively near you is active. The rest is basically hibernating and "wakes up" when you start traveling through it. So parts of this power system that were beyond your active zone would essentially be idle.
What if once a connection was established the power relays would load the blocks connected to the initial one and link them to the final output so it would permanently load the tech producing power as well as the final tech in the chain, with the rest needed to create the connection.
