Computers with coffee warmer Printer Friendly Version
Newer processors are larger, faster and consume more power. Power consumption equates largely with heat generation, and keeping them them cool can be a major concern. So my idea is, use this heat generated to keep your coffee warm. Every computer has a coffee cup holder and when you turn on the switch the generated heat is used to keep your coffee warm.

Invisible Keyboard Printer Friendly Version
They need to make a keyboard that you can't see. It's just a little a pyramid type thing that stand up in front of you and when you turn on your computer. It shines the keyboard on your desk. When you type you hit the projected keys on your desk and it senses the position of your fingers.

New Computer Mice Printer Friendly Version
Mice have come a long way in the last few years with the invention of the optical mouse e.t.c. The optical mouse still has several problems.
1) They are still surface dependent - will not work on glass e.t.c.
2) Cordless optical mice drain batteries very fast, especially when playing games. (Solar panels add around 25% more life)
My idea is to use an accelerometer to measure the changes in direction, and hence the position of the cursor on the screen. I believe that the accelerometer would be far more efficient than optical mice, and it would not be surface-dependent. A similar one used in radio controlled helicopters could be used.
With the chance that 3d monitors may be appearing in the future, an additional accelerometer could be introduced to allow positioning of the cursor in three space.
The only downside I could see of using an accelerometer is that you couldn’t used it in a car or plane and that the device would need to be very sensitive.
