The Department of Mechanical Engineering at Toyohashi University of Technology has developed an inside-out fire extinguisher for use inside spacecraft. Instead of spraying out extinguishing agents at a fire, the Vacuum Extinguish Method (VEM) sucks the flames and burning materials into a vacuum chamber, where they can be safely suffocated or extinguished.
