In the days of the horse and buggy, when there was a fire, they put it out with water. Since those days, we can now fly, have gone to the moon, have gone from capturing and preserving sound from cylinders, wire, tape, now digi, and how do we "still" put out a fire? We put water on it. It seems that technology has not caught up to fire fighting. Sure we use Fostek mixed with water, but the key principle is the same. It blows my mind seeing these giant aircraft skimming just inches off the water, gear up with full flaps scooping up water from a large lake. Those pilots must have nerves of steel. A few inches too low, the drag would force the aircraft into the lake. Water seems the only feasable way because the flame needs to be extinguished and the hot embers prevented from flaring up again. I remember a guy Red ? put out oil well fires with a bomb that sucked out all the O/2, but unlike these wild fires, there were no glowing embers to reignite. The loss here is devestating. Fire fighting technology needs to reinvent itself. perhaps dropping a mixture that produces CO/2 when exposed to flame/fire? Could that starve all the O/2 out long enough to extinguish the hot glowing embers? Water works, but so did cylinders, wire, and tape. There must be a better more efficient way that has still yet to be explored. There IS a better way, it just hasn't been thought up yet.

I can appreciate your point that we still use a high-tech version of a "Bucket Brigade" only with planes as bigger buckets.  But as audio people our job is not to put out the fire but to record it to best advantage.  We have not yet gotten to a point where we autotune the fire.  Being a purist in this matter I suggest we mic the fire with a vintage Shure 57, just slightly to the right of center.  How closely we mic is due to heat and proximity effect.

LOL There are some here who would say put the 57 close mic'd, and let it burn. I have some friends who lost everything up in smoke. He was out with a water hose doing what he could up to the very end and was forced to leave, Can't imagine what was going through his mind

With any technology comes a trade off. The vast amount of rude chemicals needed to put out a wildfire would likely trigger another ecological disaster as bad or worse than the fire. And then there's the cost. A bottle of retardant in our computer center is several thousand dollars.

Maybe someone could invent a device that creates a temporary force field structure that would surround the fire, fill with smoke and put it out with oxygen starvation?

Yes, if they could somehow come up with a way to have the low frequencies cover a massive area this could work.  From what I've read it is being worked on.

Or slowly creep across the fire area--like a rolling pin 'flattening down' the fire as it goes.  It seems to me an acoustician described low frequency standing waves as "low velocity, high particle" waves and that's why, energy-wise, the main low frequency problems in a room can be effectively dealt with near walls--where the particles build up.  Maybe the low frequencies create an impenetrable 'blanket' that starves the base of the fire as the sound energy is applied.  (Still haven't heard the YouTube with the sound on--in case this is what they already said).

I think if I lived in a wooded area, I would have a fireproof blanket to cover the structure. Almost every house was ignited by burning embers flying through the air
