Okay, so this green gadget from designer Weng Jie is still only a concept, albeit a good one.  Charge your camera while you shoot.  With an adapter you could also probably charge your phone.

Soon many everyday objects will be tapping into the sun’s solar power to extend battery life, or power their operation.  You’ll be freed from turning your domicile upside-down in search of that elusive phone charger.  And driving around with a dozen devices plugged into your car’s cigarette lighter will be a thing of the past.  I’m so old I still remember when a car’s cigarette lighter was actually used for lighting cigarettes….
