Famed yacht-fanatic Roman Abramovich added a new feature to his 557-foot, $1.2 billion monstrosity, Eclipse: A laser shield that sweeps the boat's surroundings for paparazzi and then fires a bolt of light at the camera to destroy any photo.
The lasers detect CCDs, or charge-coupled devices, which are used in most (but not all; CMOS chips are also around) photoelectric sensors. Guards can activate the lasers when they spot any suspicious glint of a camera's lens, which will then shoot a bright, focused light directly at the camera, ruining any photography.
