New product shuts car engines off with a radio pulse
The company E2V has developed a prototype device that uses a radio-frequency pulse to shut down a car’s engine at range, according to a report from the BBC. While the range of the device is fairly short, it worked on a handful of cars and motorbikes and could also potentially be used on boats.
The product, named the RF Safe-stop, works by sending an RF pulse to a car at up to 50 meters (164 feet) away. The pulse “confuses” the car’s electronic systems, which the BBC said made the “dashboard warning lights and dial [behave] erratically.” The engine then stalls, and the car comes to a stop. How safely and quickly the vehicle would stop depends on the vehicle, and this technique would not work on older vehicles.
