Whether in Canada, California or around the Mediterranean — forest fires are becoming more frequent and, above all, more severe around the world. Especially in summer, heat, drought and wind often turn such fires into raging infernos, and the climate crisis is certainly not helping. Researchers at the Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut, EMI, and start-up CAURUS Technologies GmbH are responding to the increasing global threat. Together, they are developing an innovative extinguishing method that can be used to fight large-scale fires more efficiently from the air.
