Hi This is in continuation to: http://www.madsci.org/posts/archives/2006-04/1145316546.Ph.r.html Can mobile phones be charged (to a small extent) by using sound to electrical transducers? There are two reasons I am asking this:  The dispersion of sound will be lesser as the distance of mouth is close to the mobile.  The more a person talks, the more it can get charged. So it gets charged as per usage. Assumptions:  I am considering very basic mobile phones which dont have any multimedia features etc., which means lesser battery consumption.  I am mentioning this as an complement to Solar mobile phones chargers. Thanks Niket.
