The new tech gadget showed up in tokyo in the Techno frontier 2010 this week.The new battery developed by the Japanese company Brothers Industries which is a rechargeable cell. The tinkling feature of this cell is that it can be recharged by just shaking it. The variants come as the AA and AAA batteries usable in the remotes, hand-held players etc.
       The generator comes in either a single case or as a battery attached to a generator(as can be seen). It can produce up to 3.2 volts with a coil, magnet and condenser.But reports make it unclear that how long we have to shake it to recharge the battery. But as a Eco-friendly alternative we have big hopes with it.
