The Need
Current firefighting methods often rely on water, toxic foams, or pre-installed systems, which can strain resources, pose environmental hazards, and limit portability. There is a growing demand for safer, non-toxic, and portable fire suppression solutions that can be rapidly deployed in diverse settings, including areas with limited water access or where environmental impact is a concern.

The Technology
This technology, developed by OSU researchers, utilizes a handheld device that generates vortex rings carrying conductive aerosols to suppress fires at a distance. By extending the reach of an electric arc through aerosolized conductive materials, the device can reliably extinguish flames up to nearly 2 meters away. The system combines vortex ring propulsion with electrically assisted “ionic wind” fire suppression, offering a novel, portable approach to fire control without reliance on water or toxic chemicals.

Commercial Applications
• Portable fire extinguishers for residential, industrial, and outdoor use
• Fire suppression in aerospace and transportation sectors
• Point-defense systems for manufacturing and metallurgy
• Safety testing and maintenance of electrical infrastructure

Benefits/Advantages
• Non-toxic and environmentally friendly
• Portable and easy to deploy
• Effective at a distance, enhancing user safety and operational flexibility
• Reduces reliance on water and toxic foams
