In a word… HOLY CRAP!!
“Researchers mounted the Maritime Laser Demonstrator, a solid-state laser, aboard the USS Paul Foster, a decommissioned destroyer. Off the central California coast near San Nicholas Island on Wednesday, the laser fired a 15-kilowatt beam at an inflatable motorboat a mile away as both ships moved through the sea. As the above video shows, there was a flash on the boat’s outboard engines, igniting both of them in seconds, and leaving the ship dead in the choppy waters.”
