The Mobile World Congress saw the launch of a variety of eco-friendly cellphones, which were either powered by renewable sources of energy or were made from sustainable materials. While most of us think that a solar-powered cellphone is a great green gadget, Chinese industrial designer Leon Zhu thinks that integrating solar panels isn’t practical since cellphones are mostly kept in bags or pockets.
The designer has come up with a solution – Green Badge. The device is an independent solar cell module that carries a photo-electric conversion coat and an ultrathin battery pack to store solar energy. The device is designed to be equipped with a pun at its leafstalk that can be used to conveniently clip the device onto clothes and bags.
