This is a great idea. The device is able to generate energy from any kind of noise and that energy could be used for virtually anything, for example street lamps. The designers that worket on this project are: Jihoon Kim, Boyeon Kim, Myung-Suk Kim, and Da-Woon Chung.One Sonea unit measures 450mm by 450mm by 80mm and weights 7 kilograms. It is able to convert 30 watts of power per decibel of sound that it catches.
The device is made using polycarbonate elements, ABS, and some other components.
Let's say that one airplane liftoff generates a noise around 140dB. Thus, using Sonea, it would be possible to produce about 240kW of energy. Considering about 500 airplanes each day, it would be possible to generate about 120MW of energy. In one year Sonea will be able to generate the amount energy that is equivalent to energy produced by 8000tons of oil.
