The next time you walk down the street and see some suit spazzing out, don't assume he's crazy (unless he's foaming at the mouth), maybe he's just recharging his digital camera, or any other electronic device that uses AA or AAA batteries. That's because the eggheads at Brother Industries Ltd. have put together vibration-powered generators capable of giving the company's prototype batteries a shot of juice when shaken.

"The new generator will semi-permanently eliminate the need to replace batteries and contribute to reducing the amount of wastes," Brother Industries explains.

Brother Industries' AA-size prototype with the generator and rechargeable battery installed in different cases.
In their current form, these aren't going to replace AA or AAA batteries in high-powered gadgets, but for things like remote controls and other low-power devices that don't constantly consume power, these AA/AAA lookalikes offer a serviceable replacement. According to Brother Industries, these new batteries can be used in devices with a maximum power consumption of around 100mW.

Unlike other promising battery technologies, this could actually see the light of day, and soon. Already in prototype form, Brother Industries has been showing off the vibration-powered Generating Battery at the Techno-Frontier 2010 exhibition in Tokyo.

Back in my youth-- I'm dating myself, but that's just because no one else will date me-- we had self-winding watches. Through the action of moving, the mainspring was wound, and released slowly to provide the clock's functions.

Nice to see this idea still in use! And we can ressurect an old joke: The guy who's so lazy his self-winding smartphone always runs out of power.

I always preferred wind up watches myself. The same with wall clocks.

@ClemSnide My father still have one self-winding Seiko watch. I think watch is about 20 years old and still works perfectly.

This reminds me of that flashlight from the infomercials that you shake up to keep powered.

I can think of one vibrating device these would protentially be perfect for :-x

I possibly would. I wouldn't want to replace my batteries when they die, how wasteful would that be?

Well the impact from walking is going to cause vibration. How do you think pedometers(no not the ones used to detect pedophiles) work? :-P

Also, shaking a remote around wouldn't bother me much.

Or maybe a gaming controller? the vibration function alone would help re-energize the batteries plus if you really get into the game(or really suck at it) i'm sure you'll be moving around a lot and making plenty of vibrations lol

lol acarzt, you be throwing it around the room cause your losing... but hey its for a good cause, your helping the world by using those rechargeable battery! :D. i would probably only use it for home devices cause i don't want to look stupid out doors shaking say a camera... :)

Also, im sure just walking isn't going to generate anything much or anything at all :)

Well then you're not walking right! lol

Yea... I get angry and frustrated at stupid platformers with bad camera angles where I keep falling to my doom. So I start dropping f bombs and smashing the controller into stuff lol

Then my GF pokes her head around the corner like "wtf mate?"

Yeah fat78, that only works if somebody calls the cops; also it wouldn't be considered a domestic disturbance, it'd be considered "inconsiderate to neighbors" because it takes place inside and not on an outside place.

This remindes me of that Shake-Weight you see on TV!

Someone is going to get alot of practice, or be to tired for later sitting in front of that nice Apple after the porn is done downloading!

Or you could just invent a strap to go around your dogs leg or tail for when you scratch his belly!
