| Water Cannon
The liquid stun gun has significant advantages over the handheld electric stun devices or the electric stun devices with attachment wires capable of being projected toward targets up to 15 feet away. The liquid stun gun can engage one or more persons, and does not require attachment wires with barbed tips, which often must be surgically removed. The water stream may be moved among targets until the selected target is positively engaged before the high voltage is applied. This feature can be used to avoid stunning innocent bystanders or hostages.
This wireless stun gun technology can also be used in conjunction with a vehicle-mounted water cannon for use in crowd or riot control. Water can be sprayed on the crowd, delivering debilitating but not lethal shocks. In certain military applications the electrical current could be controlled to deliver potent electrical shocks to equipment as well as individuals.
A high-voltage electrical signal with low current is generated in a compact electronic package with 9-volt batteries. The impedance of the water stream is sufficiently low that it cannot be relied on to limit current to sure-safe levels; consequently current-limiting resistors are used to limit currents to sure-safe levels. A single stream is used to deliver the current. The return path from the target is through the capacitive impedance between the gun and the target.
The stun gun can be developed in a handheld package for use on individuals, or mounted in a vehicle for riot control or military applications. Clearly, longer ranges and longer run times can be achieved in a vehicle-mounted configuration. In the vehicle-mounted configuration, substantially higher voltages and currents can be used to attack electronic targets such as vehicle ignitions, communications, and landmines.
