By zapping the air with a pair of powerful laser bursts, researchers at the Univ. of Arizona have created highly focused pathways that can channel electricity through the atmosphere.
The technique can potentially direct an electrical discharge up to 33 feet away or more, shattering previous distance records for transmitting electricity through air. It also raises the intriguing possibility of one day channeling lightning with laser power.
