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.
+1 on that. The tower feels too weak for its size (72x72 tiles) & cost (3.5k steel only + other resources).
My suggestion would be:
1. Reduce damage period
2. Increase DPS (1200/s is less than ONE upgraded uranium-bullet gun turret)
3. Make better visuals & sound (powerful laser beam with loud noise)
4. Add burning ground effect
