Vibration absorbing, self-charging batteries

Catwell
New self-charging AA and AAA batteries are about to be introduced by Brother Industries Ltd. This "Vibration-powered Generating Battery," as the company labeled it, uses electromagnetic induction to generate power. The faux battery body houses the generator and a 500mF capacitor. Currently, the AA-size generator produces about 10-180mW.The target use is for devices that don't always draw power, like remote controls or flashlights. The output sounds fairly weak in the press release, but hopefully the technology will improve before launch, and battery waste will be a thing of the past.
 
 
If you are in Tokyo around July 21-23, 2010, be sure to check out Brother Industries's booth at the Techno-frontier 2010 Expo.

  • interesting read, and of course the use of batteries in a Vibrating environment (if we ignore the perpetual motion idea), I`m sure there`s a joke in there somewhere!? 3678.contentimage_403.png

     

    the Mountain bike is a good idea, but you`re more likely to get more from a simple Dynamo, so maybe the 2 combined, or a cars glove compartment?

    perhaps a keychain LED device?

     

    I was quite surprised when I read only a 500mF cap though? I have a pair of 10F caps rated 2.5V that would easily fit into an AA batt (both of them at the same time with room left), I can run a PIC chip with 20 LEDs set up as a "Larson scanner" for a good 47 minutes before fail with these.

    the idea`s Great! the applications are Few but non the less there, I like it!
