French scientists have found a way to laser-designate Zeus's wrath. Lightning strikes occur when the potential difference between sky and Earth builds up enough to ionize the air, and ionizing air is what lasers do. So by lasering the air, the scientists create a path of least resistance for the lightning -- a priority lane for Thor. In tests, the system was able to steer lightning strikes away from otherwise guaranteed victims of Skyblasting and even redirect bolts that had already started to form. These laser lightning rods produce positive charge streamers -- the pre-lightning paths that both sound and destroy like Ghostbuster proton packs, 10 times faster than nature.
This system is intended to protect buildings more effectively than metal lightning rods. The ability to weaponize the gods the next time the sky darkens is presumably an incidental bonus.
