Cellphone rechargers through phone talks Printer Friendly Version
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.

Kinetic Mouse Printer Friendly Version
There are kinetic wrist watches that need no battery. They just have an internal capacitor which is charged by the arm's movements. I have one such watch myself. :-)
My idea is to use the same principle for a wireless computer mouse. We move the mouse around all day long as we work. Those movements could charge the mouse's internal capacitor. This way the mouse would not need batteries! Clean, environmental-friendly energy for our moving pointer device!
How about that? ;-)

Handling loud music at night Printer Friendly Version
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.
