Power pack / green design

The concept of portable solar energy generator is to arrange soft solar energy panel ( CIGS standards) on the interior of a ball with three dimentional order. Moreover, bendable lenses are equiped to facilitate sun light focusing. Experiments have proved that the solar energy panel with three dimentional arrangement will generate 26% more power than the traditional two dimentional solar panel. ( 3D: 41% vs. 2D: 15% )
