Wireless Music Pencil Printer Friendly Version
I know that lots of people would like to listen to music during class in a very secret, efficient way. I know how it can be done.
All you need is a MP3 player, Mini Disc player, CD player or any audio device with a stereo/headphone jack. There is a small antenna that plugs into your audio device's stereo/headphone jack. You also get a specially designed pencil which has a built-in receiver and speaker at the end. So what happens is you turn on your audio device and the music is sent from the antenna and picked up by the receiver in the pencil and you hear the music from the pencil. The pencil will look almost exactly like the PhD pencils. To get the eraser, you pull on the small speaker and a cartridge about 2 inches long comes out with an eraser on the other end. When the speaker is out, it twists to turn it on/off and for volume control. The range of the antenna should reach around 6 feet.
I think this would be really sweet invention because you could just put your head on your hand with the pencil tip by your ear and you could listen to music during class or anytime since there aren't any wires to deal with.
Reward: A free antenna with pencil so i can listen to tunes during class.

Increasing battery life Printer Friendly Version
The new MacBook Pros by Apple have LED screens, instead of the traditional LCD screen. LED screens consume much less power, therefore increasing battery life. How about doing the same for the mobile phones' screens?
In fact, why not changing ALL the screens in every electronic device to LEDs?
By the way, I posted another idea yesterday about kinetic wireless mouse for the computer, and I think it could be generalized to almost every kind of electronic device. I'll explain.
Some wrist watches have no battery, they just have a small electricity generator made out of a small moving magnet attached to a soneloid and a capacitor. I own one such watch. :-) They are generally known as "kinetic".
Why not use the same kind of electricity generator/accumulator for mobile phones, for wireless mice, for whatever that moves and consumes electricity. We humans move all the time, we should be taking advantage of all that motion to generate (environmental-friendly) electricity.
Reward: As a reward for these ideas I just want one item of each of these products, i.e., one "kinetic" self-charging mobile phone; one "kinetic" wireless mouse, etc. I guess it's only fair. :-)
