If I wanted to create some technology that, when researched, changed the cooldown time for the laser turrets, how would I go about doing that?

I think I would create a set of technologies that had an empty object for the effect, but would do something on the "on_research_finished" event? Can I somehow modify the cooldown property of all turrets that a player has placed/places? Do I have to create new entities and replace all existing with the new one and replace all newly placed ones with the new one as they place them?

unless anyone else has some magical knowledge, I will assume I will have to replace every instance of the placed turret with a slightly modified entity. A rather poor design.

Yes, you need to replace entities unless your property is attached to LuaForce.

Laser turret cooldown seems like a good addition to LuaForce, maybe you can make a modding interface request.
