well,i designed (((( automatically moving to build an angle of 90 degrees with sun lights as the sun moves)))))small cells to be put on every bulding from the top or even used as decoration around the bulding..they will be flower shaped..so imagine flowers moving with the sun to absorb its energy..not one but sooo many of them
Note:if you go on you will see a picture of the one i made it is great..........
Step 1: Buy photovoltaics
Photovoltaics is the direct conversion of light into electricity. Some materials exhibit a property, known as the photoelectric effect, that causes them to absorb photons of light and release electrons. When these free electrons are captured, an electric current results that can be used as electricity.although they are expensive but what a small coast to save mother earth!!!
