Depending on the size of the gun, Battelle data confirms that a ring vortex can exit a generator at 90 miles per hour and maintain a speed of at least 60 mph for more than 50 yards. Vortex rings ...

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, ...

According to Battelle's data, a big enough version of its gun could deliver an electrically-charged ring vortex initially traveling at 90 mph (145 km/h), that would be able to maintain a speed of ...

A vortex gun which can fire doughnut-shaped rings of electrically charged gas could be by firefighters to clear hallways clogged with smoke. The gun fires rings which revolve as they travel but ...

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.

Its new gun has a special cylinder on the end that creates vortex rings that leave the barrel at 90 miles per hour, and travel for more than 50 yards at a speed of at least 60 miles per hour.

Vortex guns capable of firing doughnut-shaped rings of air have sat around as toys or oddball gadgets for years. Now a U.S. lab has added an extra kick with electrically charged rings that could ...

Engineers at the Battelle Memorial Institute are patenting a special vortex gun they developed ...

Each tororidal vortex drags a trail of fog or smoke through the air until the ring itself contains hardly any fog at all. The addition of fog makes aiming your 'gun' much easier.
