Wireless Charging at its Best?

Wireless charging - not a stranger. Wireless charging through ambient sound? Sounds like an ingenious idea. If this news were to appear on 1 April I'd definitely pass it as an April Fools joke.

The prototype device was built by a team of scientists at the Queen Mary University of London, and it’s about the size of a Nokia Lumia 925, Phys.org reports. It can generate five volts of electricity using ambient sound, which is enough to keep your device topped up throughout the day and could possibly even eliminate the charger altogether.
