Power your laptop wireless!

In the day of wireless devices, why has no one come up with a novel solution for recharging electronic devices like the laptops, iPods and mobile phones? Something I've always loved to see and use - to be able to recharge my laptop without having to connect it to the power point.

Here were some of the possible ways of getting this done...digging some of my basic physics knowledge here...

• Generate power for your laptop from key strokes - We spend some energy for very key stroke! (Remember Newton's law?? - Every action has an equal and opposite reaction!)
• Generate power from the heat expelled by your laptop's battery and the other hardware
• Use the screen's brightness to regenerate power
• Use sound from an MP3 song to generate power
• Use ambient light to generate power

Give it a thought! If the bulb glows, buzz me!
