Natter power

Here at Digitaledge, we don't normally tell you about some of the more hifalutin scientific breakthroughs we read about in the tech press. After all, many of them never produce a product we mere mortals will get to play with.

But this sounds so awesome we had to share it. According to the Korea IT Times (yeah, we know), a South Korean researcher is working on a method to recharge mobile phones using sound.

That's right, sound! We'll let CNET take care of the science bit:

The technology turns sound into electricity by employing strands of zinc oxide sandwiched between electrodes. "A sound-absorbing pad on top vibrates when sound waves hit it, causing the tiny zinc oxide wires to compress and release," Kim reports. "This movement generates an electrical current that can then be used to charge a battery."

In other words: you walk down the street, you natter to your mates, you charge your battery in the process. In theory, we're talking infinite charge here.

This would clearly be awesome, though we're sure it's a few years away from sitting in the iPhone 10. But we can think of a problem - we increasingly use our phone more as an internet contraption than an actual phone, and the way things are going in a few years time we'll hardly actually talk into it at all. Maybe Google Voice Search will have improved enough to make up the difference...
