talk more, charge less

The next time you feel your phone is running out of power, call up your best friend or head to the nearest teen hangout.

The Guardian reports that researchers at Sungkyunkwan University in Seoul, have developed an approach that aims to harness sound energy from speech, music or noise and turn it into electrical power.

For sure, this ain’t a silent revolution.

Electrical engineers have developed a new technique for turning sound into electricity, allowing a mobile to be powered up while its user holds a conversation.

The technology would also be able to harness background noise and even music to charge a phone while it is not in use.

However, there could be a downside to the innovation, if it gives people a new reason to shout into their phones as they attempt to squeeze in every extra bit of power they can.
