Fight fire with fire

We all know it is not because of the greek myth 'water element beats fire element' that fires can be extinguished. Rather, it is oxygen deprivation -such as pouring a non-flammable substance on the fire source- that achieves combustion stop. Here I present an idea that may beat any fire-extinguishing device. Bombs can be used in two efficient, fire-stopping ways: 1) Blowing fire down. That is the sample principle applied whenever we strongly, quickly breathe out on a candle flame. The sudden break in the constant, low rate of oxygen consumption shuts down the combustion process. Sure, outbreath air still has oxygen in it, but the 'knock out strike' blows the flame out as if some solid object had fell on it. 2) Either the standard bomb's vacuum after-effect or, a set of vacuum bombs along a fire front, would make the perfect 'fire can't breathe' strike we need for any fire-extinguisher to work properly. The small vacuum devices have yet another advantage in that they may be deployed on forest grounds long before any fire starts.

Kind of funny, evolution has provided some pine trees species with a very subtle form of 'survival of the hottest': in Mediterranean environments, where summer fires occur quite often, these 'pyrophytic' pine trees develop 'heat activated reproduction'. That is, the ground around them is a pool of sterile, grenade-like pine-fruits, which DEPEND on fire to become fertile, crack open and let pine seeds out. No fire, no problem. Fire alarm? Then, wait until the moment everything else has been burned above the ground level; those heat-activated seeds will re-conquer the land and sprout up, well in advance of any other species' seeds.
