In the future, you could yell and charge your phone

Nokia and scientists at Queen Mary University of London have been working on a prototype charger that can charge itself using human voices, music or background noise.

"Being able to keep mobile devices working for longer, or do away with batteries completely by tapping into the stray energy that is all around us is an exciting concept," researcher Dr Joe Briscoe said in a statement released by the university.

"We hope that we have brought this technology closer to viability."

So how does it work?

They're making use of nanorods, a type of technology that captures energy from sound through vibrations that generates electricity.

Researchers have been able to generate five volts of electricity with the device so far, which is enough to charge one phone.

Replacing normal chargers might still be difficult. 

Briscoe admits that sound vibrations may not be strong enough to eliminate current charging methods entirely.

"I believe charging phones this way could be a part of the future, but there probably isn't enough energy in sound to remove the need for conventional charging completely," Briscoe told Mashable.

"It could help to reduce how often we need to charge our phones, though."

Though this type of technology has been talked about before, this is the first time companies have started to work on it.
