Increasing battery life
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. :-)
