Adds concentrated solar energy based around heliostat mirrors, which can point at solar power towers to generate heat for heliothermal energy production, or solar lens towers to generate giant lasers.
Are the current ballistics of solar laser towers the same as those of laser towers?
What do you think about changing the trajectory to something like a flamethrower-turret where the trajectory is a ray instead of a parabola? A scorching light continuously illuminates the target area, causing fire damage to all enemies at the target location and igniting the ground.
