| Cellphone rechargers through phone talks 
Sound is a form of energy. And phones use cell/battery to run. They store electrical energy. While we talk over the phone we give out sound energy. We can have a small device which converts sound energy to electrical energy and charges the cellphone batteries while we speak. It can even be charged in a theatre, pub, discos, traffic signals basically anywhere with a decibel level.

| Handling loud music at night
I read about people complaining about neighbours that take music to a high level, or car that passes at night and disturbs the neighborhood with its boom boom woofers.There is a way to handle this problem and it's in using the new technologies provided. By linking every sound system in a city by a gprs connection, volume off sound sytems can be controlled and a law can prevent users of sound systems of increasing the volume so the volume can be locked to a certain max at night, and there would not be any way to take it higher. And at day a higher volume is permitted .In the case of a party the owner of the sound system must get a permission with the approval of neighbors or a certain fee he has to pay for them, so he can increase the sound system for max. volume for only one night or a few hours.Reward: leave my stereo without the gprs controlling device.

| Beeper inside the TV remote control
This device should be like that in some models of cordless phones: you press a button on the base( the fixed part of the phone) and the mobile part of the phone make a sound, a beep. By analogy you press a button on the TV, and the remote control (a device that I usually forget where it is in the room ) makes a beep... :)
