Sound fire extinguisher is possible

Someday forest fires can be destroyed by drones that will direct loud noises at the trees below.

Fire is also a huge problem in space.

In space, when used, the contents of the fire extinguisher would spread everywhere, but you can direct sound waves without gravity.

The 20-kilogram prototype developed by Tran and Robertson does not contain toxic chemicals and eliminates side damage from sprinkler systems.

Because sound consists of pressure waves, it can be used to destroy the air surrounding the fire, essentially blocking the supply of oxygen to the fuel.

The fire extinguisher uses low-frequency sound waves to extinguish the flame, as researchers from George Mason University in Virginia recently demonstrated with their sound fire extinguisher.

A preliminary patent application filed by the inventors gives them a year to talk publicly about the invention, test the market, and determine if it makes sense to obtain a patent.
