Step 3: METHOD 3
The reason why I thought up these ideas is beacause of a mouse I bought that is powered by induction, the same technique used to charge electric toothbrushes. As you would've guessed it runs off the power supplied by the USB port. I thought that if its possible to run a mouse on a weak magnetic field produced by alternating current, then it is surely possible to have an array of thin hardrive magnets to produce the field (the mouse would only work when moving but thats okay). For this to work the magnets would have to alternate in polarity. Yeah I know that it is probably a not a good idea to have a super powerful array of magnets sitting on your desk, especially not close to a CRT monitor. Instead of magnets you could still use a coil to produce the magnetic field, but powered by a solar panel. An even better idea would be to integrate the solar panel into the induction pad.
I will try the array of magnets and post it later on
