The video shows some examples — as far as I can tell, the firing animation is a little glitchy. I don't know if you're aware of this
As an idea for the turret, you could make it function like the artillery in the game. That is, if controlled manually, it would have a massive range, but there would also be an autonomous mode (perhaps as an unlockable research) with a much shorter range. Or maybe some beacon-scanners that, if they detect enemies nearby, would direct the turret toward them.
You could also use the generator to place a few stones on the map that contain a huge amount of ore, so that they can only be broken using this turret (which will drop the ore) or with explosives (which won’t drop anything).
