Come on, this is Dungeons and Dragons brought to life, thanks to the mad scientists of DARPA: a Wand of Fire Suppression!
The Defense Advanced Research Projects Agency, known to its friends as DARPA, has announced their latest innovation: Instant fire suppression. The goal of the research project, which was part of a joint venture with Harvard University, was to find a better way to put out fires. Instead of conventional tactics, DARPA wanted a high-tech tool that would attack the very physical make up of fire using acoustics and electromagnetism.
You might be asking, “But DARPA, we already have perfectly good means of extinguishing fires, don’t we?” Sure, but each method has some pretty major drawbacks. Chemical suppressants, which interrupts the combustion process, are only effective against some types of fires, often result in collateral damage through their use, and are usually toxic. Water and CO2 suppression work well enough by smothering fires, but they still require a physical delivery system — the logistics of which can be hampered by the tight spaces one might encounter onboard a ship, for instance.
Through their research, DARPA wanted to use the physics of fire against itself. In their own words, they sought, “a novel flame-suppression system based on destabilization of flame plasma with electromagnetic fields and acoustics techniques.” Their research paid off in the form of a handheld “wand” device which snuffs out flames.
Click through for video. The big problem is scalability (perhaps power requirements or the size of the fire), but I imagine that can be fixed with enough research. Regardless, this is beyond way-cool. It’s science fiction brought to life, technology as magic.
