Self charging batteries

Sometimes even we can be stunned by new technology. This newbie from Moixa Energy floats somewhere between the useless invention and utter genius camps but we're siding with the latter. It's a rechargeable battery with a built-in USB charger – no kidding.When the AA cell starts flagging, just pop the cap to reveal the USB plug. Slip it into a handy USB port and it starts charging. A full charge takes around seven hours and each battery has only 1300mah capacity, which puts them in the mid range of rechargeables. It's still sufficient for most power-hungry digital cameras and MP3 players and beats lugging a hulking great charger around.We can honestly say we've never been this excited by a battery. In fact, have we ever been excited by a battery?
