Cell cranks for green energy

It is not a scoop, the batteries are also green. After the batteries, solar cells could crank up a way forward for the batteries.

Indeed, the Chinese designer Qian Jiang presented his concept of rechargeable batteries to handle. They arise and are used like regular batteries, except that for the load, the crank is unfolded and it is rotated. The batteries operate then the mechanical energy generated during the movement to feed. Turning the crank for 5 minutes, the battery regains 45% of its charge. An LED light indicates the level of the load. Furthermore, the batteries can be charged with a regular battery charger.
Only downside: the crank and they include the generator take up space, sacrificing their autonomy in passing.
