Scientists at Battelle have filed a patent application for a device that shoots out rings of gas—an invention that could aid firefighters in suppressing smoke.

The vortex ring gun, which fires short, circular pulses of high pressure gas instead of bullets, has long been considered one of the most promising technologies. However, field tests have shown ...

Scientists have developed a vortex gun that delivers electrically-charged rings of gas, and that could have numerous applications.

The vortex gun fires rings that reach a high speed of 90 mph upon exiting the muzzle and travel at 60 mph over more than 150 feet. The rings revolve as they fly through the air, but remain calm ...

Inspired by the toy, Battelle scientists took the technology to the next level. Over 20 years, they have tinkered with a "vortex ring gun" that they say can be used in a number of emergency scenarios.

The gun fires rings which revolve as they travel but, like the eye of a hurricane, remain calm within the interior, allowing them to carry a payload of electrically charged air.
