'Ionic wind' vortex ring launchers extinguish fires cleanly and safely | Engineers at Ohio State University have now developed handheld tools that cleanly extinguish fires with 'ionic wind’ and vortex rings.
Fighting fire usually involves water or foam, but they can be messy and environmentally destructive. Engineers at Ohio State University have now developed handheld tools that cleanly extinguish fires with 'ionic wind’ and vortex rings.
Engineers at Ohio State University have now developed handheld tools that cleanly extinguish fires with 'ionic wind’ and vortex rings. In practice, firefighters would aim the business end of a handheld cannon at a fire, and launch these ‘ionic wind’ vortex rings to put it out. The compressed air version was found to be more efficient, and intriguingly the vortex rings alone seemed to do the job – the team saw no significant improvements when the conductive aerosols were used.
