Popular Science News | Shake ‘n Power

Popular Science News – it ain’t new, the idea of using movement to charge a device. Some of the readers might be old enough to remember the introduction of the self-winding watch in the 1960s. My friend had one but he was so lazy it kept stopping – boom, boom! Please yourself.

Now this idea is being transferred to mobile phones as a source of backup power should the phone have no charge. Shashank Priya and his colleagues at Virginia Tech in Blacksburg are designing an emergency charger  which charges itself using force generated by your fingertips clicking the keypad, or just by giving the phone a shake. Unfortunately, the power generated is not enough to keep the phone charged for anything more than emergency use, say for a quick text.

To do that you would have to angrily shake the thing for 10 minutes and then quickly text “My phone is…”, shake it for another 10 minutes, “…dead,” Shake it another 10 minutes and then send the message just before men in white coats come to take you away.
