Video: Nato demonstrates suicide bomber defence beam Scientists working for Nato in Norway have released a video demonstrating how a new shield could prevent a vehicles laden with explosives from reaching their targets. Using a high-intensity electromagnetic beam, the device can stop cars, jet skis, and even drones by interfering with the vehicles' controls. In the video above, the beam halts an approaching car in a simulation of a military checkpoint. In another test, the beam-emitting device is mounted inside the back of a vehicle, and stops another car approaching from behind. The electromagnetic beam also works against remotely detonated bombs, by jamming radio signals. Testing is set to conclude in 2014.
