Last week we showed you a review of some AA batteries that could be recharged by using a USB port on your computer. While it’s great to not need a special charger for your batteries, wouldn’t it be great if they could recharge themselves without being hooked up to another power source? That’s exactly what Brother is trying to do with these Vibration-Powered Generating Batteries.
Essentially the technology inside these batteries is similar to the flashlights that can be powered by shaking them. Since both the battery and generator are both packed into a AA-sized enclosure, the output is very minimal. Currently they can only produce around 100mW of unsustained power. While that may not seem like much, it would be perfect for TV remotes, which generally use less than 100mW. This could mean having a remote that never needs the batteries changed. I’m down with that.

I finally found a use for my hyperactive cousins. Its the green technology wave of the future. No seriously, this sounds practical and if it takes off for say, tv remotes as mentioned, its only a matter of time before they are able to scale it more practical 'sustained' energy uses
that'll put my random shaking to good use
Now, the million dollar question is: Will they rechage while being used? If so, will using them in my kids Wii remotes make them last forever?
@robroot I totally agree. These battries are pretty impressive though regardless if they can that though.
i want to buy a battery like this,where can i go?
