(Phys.org) —A UK company's prototype has shown how cars can be immobilized by blasting electromagnetic waves. RF Safe-Stop is a system that stops engines. Its ability to send electronic pulses out towards targeted vehicles forces those vehicles' engines to cut out. As a non-lethal weapon, the unit can disable the engines of not only cars but also small boats, doing the job, in just seconds, at a distance up to 50m. One suggested defense use, in temporarily disabling a vehicle's electronic systems, would be to thwart drivers using their vehicles as car bombs as well as to defend sensitive locations from cars that refuse to stop.
