For mobile phone users, a flat battery or a lost charger are among the frustrations of modern life.

Now new research promises a way to recharge phones using nothing but the power of the human voice.

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.

When does the iPon powered by methane come out (or go in depending how you look at it)?

It'd also be a great way to have phones constantly on to pick up every conversation and every activity even when you're not using it..... conspiracies abound.
