Researchers Experiment With Explosives To Fight Wildfires
aesoteric writes: "Australian researchers are a step closer to demonstrating whether explosives — rather than water — can be used to extinguish an out-of-control wildfire. The research uses a blast of air to knock the flame off its fuel source — a technique used in the oil & gas industry for decades. The latest tests were conducted in New Mexico. Firefighters are reported to be quietly optimistic about the research's potential."
The reason it works with oil fires is that the oil cools rather FAST once the flame is out.
Wood... not so much. It is a good insulator and will preserve the heat - thus the vapor from wood will still be there - and HOT. Once the oxygen gets to it, it will flame again.
