funky idea for a feature for a factorio overhaul mod (think krastorio-ish)
makes all turrets that aren't artillery-type require a material called optical sensors. these turrets become less accurate in low-light conditions and for optimal base protection at night you need to line your walls with floodlights, which also contribute to pollution a bit (light pollution)
these turrets now also have passive power draw (though in the case of non-laser turrets they dont need additional power to fire). to power their servos, sensors and such. it's not much per turret but adds up
