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.

How about a service that would enable us to key in a phone number and send a message to the phone provider's server and it would reply with the details of that user. Just like online people tracking.

How about a light as an accessory on a cell phone. You would press a button on the side of the phone and the light would go on, thereby allowing you to read a menu, a show program, or see your key hole at home or at your car in the dark. I know that many cell phones have "lighted" faces, but it's not enough light and is not easy to direct it to an area to help you see in the dark. This light would run on the cell telephone battery. This would be a very simple addition, and would be very...

The present hands-free cables using for mobile phones may became twists on usage. Like head phones to walk-man. Everytime we need to unwind the twists. For this, if we can have built-in hands free in a circular box, which will be like measuring tapes (winds internally in a circular box). One side, the jack could be kept outside which plugs into the cell and the other side speakers. This compact like hands-free box could have facility to attach with mobile phone hand set or could carry...

Compact the size of a womans powder kit, with folded over elastic edged, sanitized disposable, biodegradable phone covers, (or nets), to be stretched over any phone, ex....hotel phones, hospital phones, telephone booth phones, or any phone you may use, home, or away from home.

For the fashion conscious mobi-lady of 2004, mobile phone is no longer a communication device, it is a fashion statement. Why not provide a pocket mirror in the clamshell (samsung clamshells waste that space!) for that last minute dab of lipstick! Also a mobile which is shaped circular and can be fitted within a compact circular powder case? Would that be asking for too much?!

Most mobile phones seem to suffer from severe depressions. Owners of cheaper models won't notice, but if yours has a vibration alert, you can put it to the test: Simply place your phone on a high table and dial your own number. See how your phone slowly inches towards the edge and tries to jump off the cliff? Smart manufacturers could put and end to this lemming-like behavior by using a non-vibrating cover (e.g. rubber) for the back of the phone.

One of the biggest drawbacks of headphones is that they block oxygen supply to the ears. Hence when you use them more than a few hours a day you start getting ear related problems. So my idea is a head phone that won't give you any problems, even if you use them for 8 hours+ or more ( you know people in the service industry call centers etc , basically those people who are not audiophiles.) These head phone will have two modes, simple (no amplification) and powered mode (sound...

How many times does someone hand you a printed business card that you can never find when you need it? Imagine a slot on your mobile that you slip the card into that scans/copies it for future reference?

Create a cell network whereby each cell phone "forwards" the call to the recipient. Example: I am location A and want to speak to my friend in location B, X miles away, let's say 10 miles. I call him/her and the cell phone transmission hops and skips through other users' idle phones until it finds my friend. Network would take advantage of users whose phones are idle - on, but not in use - to transmit and amplify the calls. Each cell phone is connected to the network and is standing...
