RF Safe-Stop Shuts Down Car Engines With Radio Pulse
An anonymous reader writes with news of a device built by a company in the U.K. which uses pulses of electromagnetic energy to disrupt the electronic systems of modern cars, causing them to shut down and cut the engine. Here's a description of how it works:
"At one end of a disused runway, E2V assembled a varied collection of second-hand cars and motorbikes in order to test the prototype against a range of vehicles. In demonstrations seen by the BBC a car drove towards the device at about 15mph (24km/h). As the vehicle entered the range of the RF Safe-stop, its dashboard warning lights and dials behaved erratically, the engine stopped and the car rolled gently to a halt. Digital audio and video recording devices in the vehicle were also affected.''It's a small radar transmitter,' said Andy Wood, product manager for the machine. 'The RF [radio frequency] is pulsed from the unit just as it would be in radar, it couples into the wiring in the car and that disrupts and confuses the electronics in the car causing the engine to stall.'"
Pacemakers and implanted defibrilators monitor the function of the heart by detecting voltage gradients of milivolts. This weapon can reliably knock out electronics in a car - electronics designed to operate in a very harsh EMI environment due to the presence of the nearby igntion system and contained within the metal body of the car. An enclosure that provides a bit more protection than 5mm of glass and 70cm of flesh.
So when they say this device poses no risk to those with a pacemaker, consider me a bit skeptical of that claim.
There will be a lot of blowback from this device:
1: As mentioned above, if it fries pacemakers, insulin pumps, or heart plugs, how will wrongful death lawsuits be handled?
2: If used on a motorcycle, it can mean the rider can lose control, causing a crash, fatality, and lawsuits.
3: If used on a car, most cars are drive-by-wire. This means that brakes and steering will be made inoperable in some cars, causing an instant wreck... and subsequent lawsuits. Other cars will still have mechanical brakes and steering, but most people are used to power-assisted brakes and steering... and having their vehicle handle way differently can also cause a wreck... and lawsuit.
4: What happens if another car is hit? Radio waves can be directed in unexpected places. Yet another wreck possiblity and lawsuit.
5: Of course, the bad guys will have this technology sooner or later. Now, watch stretches of I-10 become nice kill zones for thieves who are desiring either pickup trucks for Mexican drug runs, or just to pop caps in people once their car is stopped to get soldier status in their gang.
Bad idea all around... well all but for the attorneys who will make a mint from this.
A simple Google search for "non-nuclear EMP"...
and as an added bonus probably gets you added to several lists maintained by govt agencies, such as the no-fly list
I want to mod you funny for this. But somehow it's not really funny anymore.
