'Crackle' button on mobile phones Printer Friendly Version
Have you ever been talking to somebody on your mobile and wish you could cut them off without making it too obvious? It would be nice if mobile phones had a button that would introduce a realistic random crackle and fade to your end of the link. That way, it would sound just like you were entering a bad reception area and you could cut people off without hurting their feelings.
Reward: None. I just want one on my phone.

CPU power/heat recycling Printer Friendly Version
OK the idea is this, people have found many ways of cooling down that hot CPU and some people have used it for positive ideas like makeing coffie of the heat from the cpu or keeping their food warm. Well what im wondering is why no one has taken the heat from the CPU and contained it so the computer stays cool while the contained heat is used to power the computer. Taking the heat from the CPU and turning it into energy that the computer can use instead of wasting all that energy that the computer is giving off.

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.
Reward: a free one...
