Boeing files patent to convert airplane noise into electricity
Boeing has recently filed a patent to convert the noise generated by aircraft during takeoffs and landings at airports into electricity. Commercial aircraft jet engines produce noise at around 140 decibels, not to mention the noise of the wheels during landing, the wind being cut by the wings, etc. Chin Toh, a company employee, decided to develop a method to harvest electricity from all this “wasted” acoustic energy.

By installing a number of “acoustic wave collectors” along the edge of the runways, the noise generated by the airplanes would become a source of energy, which would then be used to power some of the airport systems.
