A group of designers Jihoon Kim, Boyeon Kim, Myung-Suk Kim, and Da-Woon Chung have designed Sonea, a device that converts sound to energy. A single Sonea unit is 450mm by 450mm by 80mm, weighing in at a whole 7kg. It converts 30 watts of power per decibel of sound it intercepts. It’s made of Poly Carbonate elements, ABS, and other.
As one airplane liftoff makes noise around 140dB, the amount of energy created with the SONEA would be about 240kW. Multiplying it with 500 airplanes per day will yield 120MW total of energy. In one year it could be compared to the same amount of energy generated by 8000tons of oil.
