Stopping Cars With Microwave Radiation

Ponca City, We Love You writes "Researchers have created an electromagnetic system that can quickly bring a vehicle to a stop by sending out pulses of microwave radiation to disable the microprocessors that control the central engine functions in a car. A 200-pound unit attached to the roof of a police car can be used to stop fleeing and noncooperative vehicles. The average power emitted in a single shot is about 10 kilowatts at 100 hertz and since each radiated pulse lasts about 50 nanoseconds, the total energy output is 100 joules at a distance of 15 meters. One concern with the device is that it could cause an accident if a car is disabled and a driver loses steering control. The device could also disable other vehicles in the area so the most practical application may be for perimeter protection at remote areas. Criminals have a work-around too. Since electronic control modules were not built into most cars until 1972, the system will not work on automobiles made before that year."

    What happens when criminals get their hands on this and start disabling police cars as well? :D

    Cops say microwaves can be used safely,
    But as for me and Grandpa, we disbelieve.

    Shield the microprocessor with some left-over casserole. Microwaves never fully penetrate the the center of that mass.

    Is a device that causes those obnoxious Bass units that shake every car for 3 blocks to implode. Now that would be a useful gadget.
