Charge your phone with noise

Believe it or not, Scientists have developed a device powered by noise to charge a phone battery.
Lets say you are about to make an urgent phone call, retrieve a phone number or read an urgent text message. But just as you make to reach for your phone, you discover that its battery is down. Read more


As frustrating as this experience may be, you may not always have to fumble to the nearest electric power point – which may not really be there, especially if you are in Nigeria where electricity supply is epileptic. All you have to do is let out a deafening scream which automatically charges your phone battery. The idea sounds funny but it is actually the result of a new invention by a researcher at the Institute of Nanotechnology at Sungkyunkwan University in Seoul, South Korea, Dr. Sang-Woo Kim.



This discovery was made after new methods for using environment energy had been investigated. The thrust of the report of the research is that electricity can be generated to charge phones using human voice or the walls that insulate sound on highways.

The new device will allow mobile phones to be recharged simply by talking into them. According to Kim, it turns sound into electricity, allowing a mobile to be powered up while a conversation is in progress – and the greater the volume the greater the charge. He also hints that with future projects, “Sound power can be used for various novel applications, including cellular phones that can be charged during conversations and sound-insulating walls near highways that generate electricity from the sound of passing vehicles.”
