As Bluetooth, wifi, and other “freeing” wireless technologies become affordable and widely used we will begin to depend more and more on batteries. The battery life of a laptop is a significant buying point. The same goes for MP3 players, cameras, and computer accessories. While I lust for a Bluetooth mouse I cringe at the thought of the batteries in it running out while on the last level of Half-Life 2. This dilemma got me thinking (a dangerous thing).
We have all seen the marketing hype around kinetic powered watches. The watch captures the energy of it being moved about by your arm. It then uses that stored power to continuously power your watch. Why can’t we do that for a wireless computer mouse?
If the capturing of your hand’s kinetic energy is not a possibility how about a roller(s) or maybe a way to create static electricity?
Are there any engineers willing to enlighten me on the brilliance or stupidity of this idea?
Let the royalties pour in!
