IBM with alternative battery solution

Sometimes I wonder why didn't I came with this kind of simple yet effective ideas. All I did in kid was kill an insect with those magnifying glass but oh how I did not see that it could effectively charge batteries. Yes with 230 watts solar energy per square centimeter producing about 70 watts of useful electric power creating five times more powerful cell than common ones it is most effective way of charging the battery with solar power. Gooo IBM!!
