6. Automobile Burglar Alarm Consisting of a Detection Circuit and a Flamethrower

C harl Fourie and Michelle Wong (Johannesburg, South Africa) invented an automobile burglar alarm consisting of a detection track and a flamethrower, to provide a deterrent to carjacking. With a rising crime rate, carjacking became a serious concern in South Africa. The Blaster car modification functions as a liquefies petroleum gas flamethrower; when a carjacking occurs, the driver steps on an additional pedal next to accelerator and flames erupt from outer sides of both front doors, “neutralizing” the assailant. The inventor claims it is unlikely to kill but would “definitely blind” the assailant. In South Africa, it is legal to use lethal force in self-defence if in fear of one’s life, and ownership of flamethrower is unrestricted.
