The word of the day is “heliotropic.” That’s a fancy way of describing something that has the ability to track the movement of the sun across the sky, from east to west. Leonardo da Vinci first discovered heliotropism in plants, hundreds of years ago.
Today, solar technology has advanced to maximize the amount of energy absorbed from UV light with heliotropic solar panels. You can make your own DIY sun tracking solar panels, using directions on this video.
All you need are some solar panels from garden solar lights, an Ardunio, some CD disks, styrofoam and hot glue:
