This was argued to death on Slashdot over a week ago.

But the main thing is that there are various rules of physics which mean this simply isn't possible. Even if the noise energy from the mouth could be tapped with 100% efficiency (LMAO) then the encoding and transmission energy required would be too much.

Paris, because she gives out a lot of energy through her mouth.

I'm in an art gallery.

NO ITS RUBISH.

I JUST CALLED YOU TO CHARGE MY PHONE.

Pffft, lightweight.

My daughter could power the whole house.

When having a conversation with my girlfriend only her phone would get charged and mine would run out..... Wait a minute thats genius when can i get one!

In order to keep your phone charged, you have to yak all the time. Yeesh, people talk too much as it is.

Paris, because, man, she really vibrates it...
