And thus, noise need not be pollution anymore. According to the Telegraph, engineers at the Sungkyunkwan University in Seoul, South Korea, have developed a technology that can transform sound waves into electrical power. When applied to a cellphone, the source of power may come from all types of sound from speech, music or traffic. Charging can be done whether or not the cellphone is in use. The technology lies in a battery which has a sound-absorbing pad that converts sound vibrations into energy. Currently, the battery developed can only power sensors and other small devices, although according to its developers, applying this to smartphones is well underway in the near future.
