Recharge cell phones by talking

Researchers have successfully created a prototype battery that can turn sound waves into electricity, a technology that could one day recharge everything from cell phones to electric cars.

Of the most important features in a mobile device, a solid battery life remains key. Luckily for us all, researches in South Korea have reportedly discovered a new way to recharge cell phones using nothing more than the power of the human voice. That’s right, talking — how convenient!

According to the Telegraph, engineers at Sungkyunkwan University in Seoul, South Korea, have developed a new type of battery that’s capable of transforming the energy in sound waves into electrical energy that can be used to power a wide range of devices. When used with a mobile phone, the technology can gin up a charge using not only speech, but all background noise — the louder the better. It even works when the cell phone is not in use.

“A number of approaches for scavenging energy from environments have been intensively explored,” said Dr. Sang-Woo Kim, who has been involved in developing the technology . “The sound that always exists in our everyday life and environments has been overlooked as a source. This motivated us to realise power generation by turning sound energy from speech, music or noise into electrical power.”

The sound-power technology wouldn’t only be useful for powering up your iPhone, says Dr. Sang-Woo Kim. It could also hold the answer for a more practical recharging method for electric cars.

“Sound power can be used for various novel applications including cellular phones that can be charged during conversations and sound-insulating walls near highways that generate electricity from the sound of passing vehicles,” he says. “The latter development would have the additional benefit of reducing noise levels near highways by absorbing the sound energy of vehicles.”

The new type of battery works using a sound absorbing pad that vibrates when hit by sound waves. This vibration is then transferred to tiny strands of zinc oxide wire, which contract and release with the vibrations, turning the energy of sound into electricity.

The battery is still in small-scale form, meaning it only works with very low-power devices. But the research team is confident that its energy-scavaging creation will eventually find its way onto a smartphone spec list in the not-too-distant future.

The louder you speak, the more it will charge.

cool, that means no car chargers or shitting bricks when your blackberry is almost out of batteries in the middle of the day.

Talking louder to recharge the battery? This would be a real hit in Mainland China! :lol

as long as people on the skytrain or buses dont start talking louder at their phones.

"I CANT HEAR YOU, THAT MEANS I MUST YELL TOO"

>;C

So in the future take that same technology, put it in a music operating w/ new battery tech + play it really loud = infinite battery power? :troll:

Infinite mileage electric car, infinite garberator, jackhammer :troll:

What if you have two phones equipped with that battery playing really loud music side by side, infinite power forever!

Troll science lol. Power an entire house on nearby noise, if its large scale enough it can work as off the grid power.

With technology moving as it is, I am looking forward to zero point energy.

Put the phone near the 3" exhaust while driving when you're girl friend is bitchin' out over the phone. "Sorry baby I had to charge my phone with loud sounds so that I can listen to you longer, I swear!"

ZPM?

????

wire a dynamo and brace to your jaw. every time your jaw moves up and down, the dynamo spins and makes power.

look like a retard with bad brace, but you can keep your cell on non stop.

EDIT: lol at new mod aproved icon^^^
