Earlier this spring, the U.S. Army revealed the existence of a project underway to build a device that could shoot lightning bolts down laser beams to take out a target. Now the military's boffins report success in their first tests.
The technology -- known as laser-induced plasma channel -- is designed to seek out targets that conduct electricity better than the air or ground that surrounds them.
Although scientists and engineers working on the weapon's development expressed confidence in the physics behind their work, George Fischer, who is the lead scientist on the project, nonetheless cautioned about the technical challenges still ahead. … Read more
