Automatic Toothbrush Printer Friendly Version
I did a science fair project on this one... A tooth brush that had tooth paste in the handle which would dispense through a tube into the bristles. Of course to market such a thing it would either need to be disposable or refillable. I had a proto-type at the fair and everyone liked it. What do you guys think?
Reward: Just the satisfaction that I had a good idea.

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. :-)

Play ball with your dog, without you! Printer Friendly Version
If you have really energetic dogs at home, but you never have time to play with them, or you're too tired, this is perfect for you. It is a machine that plays fetch with your dog(s). Place it in a corner of your yard, put a time you want it to play, then let it loose. It has 10 tennis balls in a compartment inside it. Inside those balls are powerful magnets that get attracted to the machine when the machine runs out of balls. Like the machines you see in tennis courts, it will throw the balls in many directions at intervals of 20 seconds, plenty of time for your dog to chase them. Then it will neatly pick the balls up, leaving your yard balls-free.
Reward: get it for free, the ability to use it in a science fair without getting sued.
