Sphelar is prettier and more efficient than flat solar cells

E_tokucho_zu3

Where flat solar cells depend on angle to maximize how much energy they extract from sun, the Sphelar solar cell has an efficiency of nearly 20%, because it places 1mm ball-like solar cells in a flower-like pattern which can extract energy from all directions. It's also thin, flexible and transparent enough that it could be placed on regular window glass, turning those monster skyscrapers self-sufficient. Its production process is also vastly more efficient than flat solar, making it cheaper and reducing silicon waste enormously. [GT]
