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.
